Export from php mysql to excel

Recently I published an article How to Read CSV and Excel File in PHP Using PhpSpreadsheet.  One of the readers asked how to use PhpSpreadsheet to export MySQL database records to the Excel file. The user may need their MySQL data in the Excel or CSV file to read or share it easily. In this article, we discussed how one can export data from a database to Excel and CSV files. In addition to this, we will also study how one can send this exported file as an attachment in the email.

Getting Started

For getting started, you first need to install the PhpSpreadsheet library. I recommend using Composer for the installation of the library. Open the terminal in your project root directory and run the command:

composer require phpoffice/phpspreadsheet

PhpSpreadsheet is the library that provides support for reading and writing different types of file formats. Below is the screenshot of supported file formats.

Our end goal is exporting database table records to the Excel/CSV file. For this, we require a few entries in our database. As an example, I am creating the ‘products’ table by running the below SQL query.

CREATE TABLE `products` (
 `id` int(11) NOT NULL AUTO_INCREMENT,
 `product_name` varchar(255) NOT NULL,
 `product_sku` varchar(255) NOT NULL,
 `product_price` varchar(255) NOT NULL,
 PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1;

Next, add some dummy entries in the table so you will see a few records in the exported file.

INSERT INTO `products` (`product_name`, `product_sku`, `product_price`) VALUES
('Apple', 'app_111', '$1000'),
('Lenovo', 'len_222', '$999'),
('Samsung', 'sam_689', '$1200'),
('Acer', 'ace_620', '$900');

After this create a config.php file where we write the code for database connection.

config.php

<?php
$db_host = 'DATABASE_HOST';
$db_username = 'DATABASE_USERNAME';
$db_password = 'DATABASE_PASSWORD';
$db_name = 'DATABASE_NAME';
 
$db = new mysqli($db_host, $db_username, $db_password, $db_name);
 
if($db->connect_error){
    die("Unable to connect database: " . $db->connect_error);
}

Make sure to replace the placeholders with the actual values in the above code. This file will be included later to fetch records from the ‘products’ table.

In the next part of the tutorial, I am allocating a separate section for exporting data to Excel, exporting data to CSV, and sending the email with an exported file as an attachment.

Export MySQL Database Data to Excel Using PHP

You have installed the library and also have a database table with few entries. Now you can go ahead and write the actual code which will export an Excel file with data filled in it.

Create a <code>export-to-excel.php</code> file in the root directory. In this file, I will write a SQL query to fetch data from the database, write this data to Excel, and finally send the Excel file to the browser to download automatically.

export-to-excel.php

<?php
require_once "vendor/autoload.php";
require_once "config.php";
 
use PhpOfficePhpSpreadsheetSpreadsheet;
use PhpOfficePhpSpreadsheetWriterXlsx;
 
$spreadsheet = new Spreadsheet();
$Excel_writer = new Xlsx($spreadsheet);
 
$spreadsheet->setActiveSheetIndex(0);
$activeSheet = $spreadsheet->getActiveSheet();
 
$activeSheet->setCellValue('A1', 'Product Name');
$activeSheet->setCellValue('B1', 'Product SKU');
$activeSheet->setCellValue('C1', 'Product Price');
 
$query = $db->query("SELECT * FROM products");
 
if($query->num_rows > 0) {
    $i = 2;
    while($row = $query->fetch_assoc()) {
        $activeSheet->setCellValue('A'.$i , $row['product_name']);
        $activeSheet->setCellValue('B'.$i , $row['product_sku']);
        $activeSheet->setCellValue('C'.$i , $row['product_price']);
        $i++;
    }
}
 
$filename = 'products.xlsx';
 
header('Content-Type: application/vnd.ms-excel');
header('Content-Disposition: attachment;filename='. $filename);
header('Cache-Control: max-age=0');
$Excel_writer->save('php://output');

When you run this code on the browser, an Excel file will be downloaded automatically and the Excel sheet will have the following entries.

Export MySQL Database Data to CSV Using PHP

In the previous section, we exported data to an Excel file. If someone is looking to export data in a CSV file then you need to change a few lines in the above code.

export-to-csv.php

<?php
require_once "vendor/autoload.php";
require_once "config.php";
 
use PhpOfficePhpSpreadsheetSpreadsheet;
use PhpOfficePhpSpreadsheetWriterCsv;
 
$spreadsheet = new Spreadsheet();
$Excel_writer = new Csv($spreadsheet);
 
$spreadsheet->setActiveSheetIndex(0);
$activeSheet = $spreadsheet->getActiveSheet();
 
$activeSheet->setCellValue('A1', 'Product Name');
$activeSheet->setCellValue('B1', 'Product SKU');
$activeSheet->setCellValue('C1', 'Product Price');
 
$query = $db->query("SELECT * FROM products");
 
if($query->num_rows > 0) {
    $i = 2;
    while($row = $query->fetch_assoc()) {
        $activeSheet->setCellValue('A'.$i , $row['product_name']);
        $activeSheet->setCellValue('B'.$i , $row['product_sku']);
        $activeSheet->setCellValue('C'.$i , $row['product_price']);
        $i++;
    }
}
 
$filename = 'products.csv';
 
header('Content-Type: application/text-csv');
header('Content-Disposition: attachment;filename='. $filename);
header('Cache-Control: max-age=0');
$Excel_writer->save('php://output');

Send an Email with File as an Attachment

We have seen how to download the file with data in Excel/CSV format. Some users may want to send the exported file as an attachment in the email. Let’s see how to achieve it.

First, install the PHPMailer library using the command:

composer require phpmailer/phpmailer

After installing the library, you can use any SMTP server to send an email. It’s up to you. You may use your hosting SMTP server, AWS SES, or Gmail SMTP server. If you are going with the Gmail SMTP server read our article Send Email Using Gmail SMTP Server from PHP Script which explains the configuration needed for it.

The previous code download Excel/CSV file automatically. But now, instead of making it downloadable, we will save the file in the directory and then send it as an attachment. In short, we will write the code below for saving the file.

...
...
$filename = 'products.csv';
 
if (!file_exists('files')) {
    mkdir('files', 0755);
}
$Excel_writer->save('files/'.$filename);

Our final code to send the attachment in an email will be as follows:

<?php
require_once "vendor/autoload.php";
require_once "config.php";
 
use PhpOfficePhpSpreadsheetSpreadsheet;
use PhpOfficePhpSpreadsheetWriterCsv;
 
//Import PHPMailer classes into the global namespace
use PHPMailerPHPMailerPHPMailer;
use PHPMailerPHPMailerException;
 
$spreadsheet = new Spreadsheet();
$Excel_writer = new Csv($spreadsheet);
 
$spreadsheet->setActiveSheetIndex(0);
$activeSheet = $spreadsheet->getActiveSheet();
 
$activeSheet->setCellValue('A1', 'Product Name');
$activeSheet->setCellValue('B1', 'Product SKU');
$activeSheet->setCellValue('C1', 'Product Price');
 
$query = $db->query("SELECT * FROM products");
 
if($query->num_rows > 0) {
    $i = 2;
    while($row = $query->fetch_assoc()) {
        $activeSheet->setCellValue('A'.$i , $row['product_name']);
        $activeSheet->setCellValue('B'.$i , $row['product_sku']);
        $activeSheet->setCellValue('C'.$i , $row['product_price']);
        $i++;
    }
}
 
$filename = 'products.csv';
 
if (!file_exists('files')) {
    mkdir('files', 0755);
}
$Excel_writer->save('files/'.$filename);
 
// send as an attachment
$mail = new PHPMailer(true);
try {
    $mail->isSMTP();
    $mail->Host = 'SMTP_HOST';
    $mail->SMTPAuth = true;
    $mail->Username = 'SMTP_USERNAME';   //username
    $mail->Password = 'SMTP_PASSWORD';   //password
    $mail->SMTPSecure = 'ssl';
    $mail->Port = 465;
 
    $mail->setFrom('FROM_EMAIL_ADDRESS', 'FROM_NAME');
    $mail->addAddress('RECEPIENT_EMAIL_ADDRESS', 'RECEPIENT_NAME');
 
    $mail->addAttachment('files/'.$filename);
 
    $mail->isHTML(true);
    $mail->Subject = 'Products Sheet';
    $mail->Body    = 'Products Sheet';
 
    $mail->send();
    echo 'Message has been sent';
} catch (Exception $e) {
    echo 'Message could not be sent. Mailer Error: '. $mail->ErrorInfo;
}

Replace the placeholders with the actual values and an email will be sent with an attachment to the recipient’s email address.

Export MySQL Data To Excel in PHP

Because Excel is the finest format for storing data in a file, exporting data in Excel format is a very important tool that allows users to save data for offline use. You’ll learn how to use PHP and MySQL to export data to Excel.

So the file structure for this example is the following:

• index.php: This is the entry file.
• connection.php: This file is used to connect MySQL with PHP
• generate_excel.php: This is the main PHP file that’ll have an export method to export data into the excel.

Create MySQL Database Table

Let’s create a tasks table that ll all tasks records which will export later on in excel format.

CREATE TABLE `tasks` (
  `id` int(11) NOT NULL,
  `Name` varchar(255) NOT NULL,
  `Status` varchar(255) NOT NULL,
  `Priority` varchar(255) NOT NULL,
  `Date` date NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=latin1;

--
-- Indexes for table `tasks`
--
ALTER TABLE `tasks`
  ADD PRIMARY KEY (`id`);
--
-- AUTO_INCREMENT for table `tasks`
--
ALTER TABLE `tasks`
  MODIFY `id` int(11) NOT NULL AUTO_INCREMENT, AUTO_INCREMENT=5;
COMMIT;

Now, I’ll insert some sample data into the tasks table.

INSERT INTO `tasks` (`id`, `Name`, `Status`, `Priority`, `Date`) VALUES
(1, 'Task1', 'Completed', 'Low', '2021-09-01'),
(2, 'Task2', 'InProgress', 'High', '2021-03-17'),
(3, 'Mysql', 'Hold', 'Low', '2021-09-22'),
(4, 'API', 'Pending', 'Low', '2021-09-06');

Create MySQL Connection With PHP

We’ll create a connection.php file and add the below code. in this file, We’ll pass the database hostname, database username, database password, and database name.

<?php
Class dbObj{
	/* Database connection start */
	var $dbhost = "localhost";
	var $username = "root";
	var $password = "";
	var $dbname = "test";
	var $conn;
	function getConnstring() {
		$con = mysqli_connect($this->dbhost, $this->username, $this->password, $this->dbname) or die("Connection failed: " . mysqli_connect_error());

		/* check connection */
		if (mysqli_connect_errno()) {
			printf("Connect failed: %sn", mysqli_connect_error());
			exit();
		} else {
			$this->conn = $con;
		}
		return $this->conn;
	}
}
?>

Get the Tasks Data from MySQL Database Table

We’ll receive entries from a MySQL database table tasks and put them in an array so we can show them and export them to an excel file. Added below code into the top of the generate_excel.php file.

include_once("connection.php");
$db = new dbObj();
$connString =  $db->getConnstring();

$sql_query = "SELECT * FROM tasks";
$resultset = mysqli_query($connString, $sql_query) or die("database error:". mysqli_error($conn));
$tasks = array();
while( $rows = mysqli_fetch_assoc($resultset) ) {
	$tasks[] = $rows;
}

Export Data to Excel

Let’s create export features using PHP and export data into excel. We’ll also force the to browser download the file instead of display it. We’ll add the below code into the generate_excel.php file.

if(isset($_POST["ExportType"]))
{
	 
    switch($_POST["ExportType"])
    {
        case "export-to-excel" :
            // Submission from
			$filename = "phpflow_data_export_".date('Ymd') . ".xls";		 
            header("Content-Type: application/vnd.ms-excel");
			header("Content-Disposition: attachment; filename="$filename"");
			ExportFile($tasks);
			//$_POST["ExportType"] = '';
            exit();
        default :
            die("Unknown action : ".$_POST["action"]);
            break;
    }
}
function ExportFile($records) {
	$heading = false;
		if(!empty($records))
		  foreach($records as $row) {
			if(!$heading) {
			  // display field/column names as a first row
			  echo implode("t", array_keys($row)) . "n";
			  $heading = true;
			}
			echo implode("t", array_values($row)) . "n";
		  }
		exit;
}

the code shown above, The switch case block will execute based on the parameter value and the method invoked.
Browsers are being forced to download an excel file.

Create HTML and Display Records with Export Button

Define html layout for display data in table and button to fire export-to-csv action. Added below code into the index.php file.

<?php 
include_once("generate_excel.php");
?>

            <tbody>
                <?php foreach($tasks as $row):?>

                <tr>
                    <td><?php echo $row ['Name']?></td>

                    <td><?php echo $row ['Status']?></td>

                    <td><?php echo $row ['Priority']?></td>

                    <td><?php echo $row ['Date']?></td>
                </tr>

                <?php endforeach; ?>
            </tbody>
        </table>
    </div>
</div>

We’ve imported the ‘generate_excel.php’ file at the top of the code, which will yield task data for display in the HTML table. We’ve established a dropwodn with a ‘export to excel’ option. All task data will be displayed in an HTML table.

Submit Form Using jQuery

We’ve included a dropdown and need to catch and fire events so that when a user selects an option, the form is submitted. We’ll paste the code below at the bottom of the index.php file.

<script type="text/javascript">
$(document).ready(function() {
jQuery('#Export to excel').bind("click", function() {
var target = $(this).attr('id');
switch(target) {
	case 'export-to-excel' :
	$('#hidden-type').val(target);
	//alert($('#hidden-type').val());
	$('#export-form').submit();
	$('#hidden-type').val('');
	break
}
});
    });
</script>

Result:

I hope its help you!.

Export Data to Excel is a popular feature of web applications to allow dynamic data export to Excel file to save locally for further use. If you’re a PHP developer and thinking to implement data export to excel, then you’re here at right place. You will learn here how to implement data export to excel using PHP & MySQL.

In our previous tutorial you have learned how to export data to excel in CodeIgniter, now in this tutorial we will explain how to export data to excel with PHP and MySQL.

We will cover this tutorial step by step to create live demo to implement data export to excel with PHP and MySQL. You can also download complete source code of live.

Also, read:

• Export Data to Excel with PhpSpreadsheet using CodeIgniter
• Export Data to CSV File with PHP and MySQL
• Export HTML Table Data to Excel, CSV and Text with jQuery, PHP and MySQL

So let’s start implementing data export to excel with PHP and MySQL. Before we begin, take a look on files structure for this example.

• index.php:
• export.php:

Step1: Create MySQL Database Table

As we will cover this tutorial with example to export data to Excel file, so first we will create MySQL database table developers to store developer records.

CREATE TABLE `developers` (
  `id` int(11) NOT NULL,
  `name` varchar(255) NOT NULL,
  `skills` varchar(255) NOT NULL,
  `address` varchar(255) NOT NULL,
  `gender` varchar(255) NOT NULL,
  `designation` varchar(255) NOT NULL,
  `age` int(11) NOT NULL,
  `image` varchar(255) NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=latin1;

We will also insert few records to this table.

INSERT INTO `developers` (`id`, `name`, `skills`, `address`, `gender`, `designation`, `age`, `image`) VALUES
(1, 'Smith', 'Java', 'Newyork', 'Male', 'Software Engineer', 34, 'image_1.jpg'),
(2, 'David', 'PHP', 'London', 'Male', 'Web Developer', 28, 'image_2.jpg'),
(3, 'Rhodes', 'jQuery', 'New Jersy', 'Male', 'Web Developer', 30, 'image_2.jpg'),
(4, 'Sara', 'JavaScript', 'Delhi', 'Female', 'Web Developer', 25, 'image_2.jpg'),
(5, 'Shyrlin', 'NodeJS', 'Tokiyo', 'Female', 'Programmer', 35, 'image_2.jpg'),
(6, 'Steve', 'Angular', 'London', 'Male', 'Web Developer', 28, 'image_2.jpg'),
(7, 'Cook', 'MySQL', 'Paris', 'Male', 'Web Developer', 26, 'image_2.jpg'),
(8, 'Root', 'HTML', 'Paris', 'Male', 'Web Developer', 28, 'image_2.jpg'),
(9, 'William', 'jQuery', 'Sydney', 'Male', 'Web Developer', 23, 'image_2.jpg'),
(10, 'Nathan', 'PHP', 'London', 'Male', 'Web Developer', 28, 'image_2.jpg'),
(11, 'Shri', 'PHP', 'Delhi', 'Male', 'Web Developer', 38, 'image_2.jpg'),
(12, 'Jay', 'PHP', 'Delhi, India', 'Male', 'Web Developer', 30, 'image_3.jpg');

Step2: Get Records from MySQL Database Table

In export.php file, we will get developer records from MySQL database table developers and store into an array.

include_once("db_connect.php");
$sqlQuery = "SELECT name, gender, age, skills, address, designation FROM developers LIMIT 10";
$resultSet = mysqli_query($conn, $sqlQuery) or die("database error:". mysqli_error($conn));
$developersData = array();
while( $developer = mysqli_fetch_assoc($resultSet) ) {
	$developersData[] = $developer;
}	

Step3: Display Records with Export to Excel Button

In index.php file, we will display developer records from $developersData array. We will also add data export button to export data.

<div class="container">		
	<div class="well-sm col-sm-12">
		<div class="btn-group pull-right">	
			<form action="<?php echo $_SERVER["PHP_SELF"]; ?>" method="post">					
				<button type="submit" id="dataExport" name="dataExport" value="Export to excel" class="btn btn-info">Export To Excel</button>
			</form>
		</div>
	</div>				  
	<table id="" class="table table-striped table-bordered">
		<tr>
			<th>Name</th>
			<th>Gender</th>
			<th>Age</th>
			<th>Skills</th>			
			<th>Address</th>
			<th>Designation</th>
		</tr>
		<tbody>
			<?php foreach($developersData as $developer) { ?>
			   <tr>
			   <td><?php echo $developer ['name']; ?></td>
			   <td><?php echo $developer ['gender']; ?></td>
			   <td><?php echo $developer ['age']; ?></td>  
				<td><?php echo $developer ['skills']; ?></td>			   
			   <td><?php echo $developer ['address']; ?></td>
			   <td><?php echo $developer ['designation']; ?></td>   
			   </tr>
			<?php } ?>
		</tbody>
    </table>		
</div>

Step4: Implement Data Export to Excel

Now we will implement export data to excel when export button clicked. We will use $developersData array for data exported and saved into an xlsx file.

<?php
if(isset($_POST["dataExport"])) {	
	$fileName = "webdamn_export_".date('Ymd') . ".xls";			
	header("Content-Type: application/vnd.ms-excel");
	header("Content-Disposition: attachment; filename="$fileName"");	
	$showColoumn = false;
	if(!empty($developersData)) {
	  foreach($developersData as $developerInfo) {
		if(!$showColoumn) {		 
		  echo implode("t", array_keys($developerInfo)) . "n";
		  $showColoumn = true;
		}
		echo implode("t", array_values($developerInfo)) . "n";
	  }
	}
	exit;  
}
?>

Export data feature is very useful where the data is saved on the local drive for offline uses. Export data to file functionality provides a user-friendly way to maintain a large number of data in the web application. There are various file formats are available to export data and download it as a file. Microsoft Excel is a widely used spreadsheet format that organizes and maintains data.

Generally, export data functionality is used in the data management section of the web application. Excel is the best format to export data in a file and you can easily export data to excel using PHP. In this tutorial, we will show you how to export data to Excel in PHP.

The example PHP script lets you integrate export data to excel functionality. With one click, the user can export data from the MySQL database to Excel and download it in MS Excel file format (.xls/.xlsx).

Export Data to Excel with PHP

In this example script, we will export data from the array (defined in the script) to an excel file.

The $data variable holds the data in array format which will be exported to Excel using PHP.

$data = array( 
    array("NAME" => "John Doe", "EMAIL" => "john.doe@gmail.com", "GENDER" => "Male", "COUNTRY" => "United States"), 
    array("NAME" => "Gary Riley", "EMAIL" => "gary@hotmail.com", "GENDER" => "Male", "COUNTRY" => "United Kingdom"), 
    array("NAME" => "Edward Siu", "EMAIL" => "siu.edward@gmail.com", "GENDER" => "Male", "COUNTRY" => "Switzerland"), 
    array("NAME" => "Betty Simons", "EMAIL" => "simons@example.com", "GENDER" => "Female", "COUNTRY" => "Australia"), 
    array("NAME" => "Frances Lieberman", "EMAIL" => "lieberman@gmail.com", "GENDER" => "Female", "COUNTRY" => "United Kingdom") 
);

The filterData() function is used to filter string before added to the excel sheet row.

function filterData(&$str){ 
    $str = preg_replace("/t/", "\t", $str); 
    $str = preg_replace("/r?n/", "\n", $str); 
    if(strstr($str, '"')) $str = '"' . str_replace('"', '""', $str) . '"'; 
}

The following code helps to export data in excel and download it as a file.

• The $fileName variable defines the name of the excel file.
• The Content-Disposition and Content-Type headers force the excel file to download.
• Run the loop through each key/value pair in the $data array.
• Display column names as the first row using the $flag variable.
• The PHP array_walk() function is used to filter the data together with filterData() function.

// Excel file name for download 
$fileName = "codexworld_export_data-" . date('Ymd') . ".xlsx"; // Headers for download 
header("Content-Disposition: attachment; filename="$fileName""); 
header("Content-Type: application/vnd.ms-excel"); $flag = false; 
foreach($data as $row) { 
    if(!$flag) { 
        // display column names as first row 
        echo implode("t", array_keys($row)) . "n"; 
        $flag = true; 
    } 
    // filter data 
    array_walk($row, 'filterData'); 
    echo implode("t", array_values($row)) . "n"; 
} 
 exit;



  


                       
  

Export Data from Database to Excel with PHP and MySQL

In this example script, we will export data from the MySQL database in an excel file using PHP.

Create Database Table:
For this example, we will create a members table with some basic fields in the MySQL database. The members table holds the records which will be exported to excel.

CREATE TABLE `members` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `first_name` varchar(25) COLLATE utf8_unicode_ci NOT NULL,
  `last_name` varchar(25) COLLATE utf8_unicode_ci NOT NULL,
  `email` varchar(50) COLLATE utf8_unicode_ci NOT NULL,
  `gender` enum('Male','Female') COLLATE utf8_unicode_ci NOT NULL,
  `country` varchar(20) COLLATE utf8_unicode_ci NOT NULL,
  `created` datetime NOT NULL,
  `status` tinyint(1) NOT NULL DEFAULT 1 COMMENT '1=Active | 0=Inactive',
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci;

Database Configuration (dbConfig.php):
The following code is used to connect the database using PHP and MySQL. Specify the database host ($dbHost), username ($dbUsername), password ($dbPassword), and name ($dbName) as per your database credentials.

<?php 
// Database configuration 
$dbHost     = "localhost"; 
$dbUsername = "root"; 
$dbPassword = "root"; 
$dbName     = "codexworld"; // Create database connection 
$db = new mysqli($dbHost, $dbUsername, $dbPassword, $dbName); // Check connection 
if ($db->connect_error) { 
    die("Connection failed: " . $db->connect_error); 
}

Export Data from Database:
The following code helps to export data from the MySQL database and download it as an excel file.

• The filterData() function is used to filter string before added to the excel data row.
• $fileName – Define the name of the excel file to be downloaded.
• $fields – Define the column named of the excel sheet.
• $excelData – Add the first row to the excel sheet as a column name.
• Fetch member’s data from the database and add to the row of the excel sheet.
• Define headers to force the file to download.
• Render data of excel sheet.

<?php 
// Load the database configuration file 
include_once 'dbConfig.php'; // Filter the excel data 
function filterData(&$str){ 
    $str = preg_replace("/t/", "\t", $str); 
    $str = preg_replace("/r?n/", "\n", $str); 
    if(strstr($str, '"')) $str = '"' . str_replace('"', '""', $str) . '"'; 
} // Excel file name for download 
$fileName = "members-data_" . date('Y-m-d') . ".xls"; // Column names 
$fields = array('ID', 'FIRST NAME', 'LAST NAME', 'EMAIL', 'GENDER', 'COUNTRY', 'CREATED', 'STATUS'); // Display column names as first row 
$excelData = implode("t", array_values($fields)) . "n"; // Fetch records from database 
$query = $db->query("SELECT * FROM members ORDER BY id ASC"); 
if($query->num_rows > 0){ 
    // Output each row of the data 
    while($row = $query->fetch_assoc()){ 
        $status = ($row['status'] == 1)?'Active':'Inactive'; 
        $lineData = array($row['id'], $row['first_name'], $row['last_name'], $row['email'], $row['gender'], $row['country'], $row['created'], $status); 
        array_walk($lineData, 'filterData'); 
        $excelData .= implode("t", array_values($lineData)) . "n"; 
    } 
}else{ 
    $excelData .= 'No records found...'. "n"; 
} // Headers for download 
header("Content-Type: application/vnd.ms-excel"); 
header("Content-Disposition: attachment; filename="$fileName""); // Render excel data 
echo $excelData; 
 exit;
