Count number of word in string

// Jonny 5's simple word splitter

<?php

$str = "Hello fri3nd, you're

       looking          good today!

       look1234ing";

print_r(str_word_count($str, 1, '0..3'));

?>



will give the result as

Array ( [0] => Hello [1] => fri3nd [2] => you're [3] => looking [4] => good [5] => today [6] => look123 [7] => ing )

}

I removed some of the separators which don't work well with Hebrew ("x20", "xA0", "x0A", "x0D", "x09", "x0B", "x2E"). I also removed the underline.

This is a fix to my previous post on this page - I found out that my function returned an incorrect result for an empty string. I corrected it and I'm also attaching another function - my_strlen.

<?php function count_words($string) {
    // Return the number of words in a string.
    $string= str_replace("'", "'", $string);
    $t= array(' ', "t", '=', '+', '-', '*', '/', '\', ',', '.', ';', ':', '[', ']', '{', '}', '(', ')', '<', '>', '&', '%', '$', '@', '#', '^', '!', '?', '~'); // separators
    $string= str_replace($t, " ", $string);
    $string= trim(preg_replace("/s+/", " ", $string));
    $num= 0;
    if (my_strlen($string)>0) {
        $word_array= explode(" ", $string);
        $num= count($word_array);
    }
    return $num;
}

function

my_strlen($s) {
    // Return mb_strlen with encoding UTF-8.
    return mb_strlen($s, "UTF-8");
}?>

It returns a string with a certain character limit, but still retaining whole words.
It breaks out of the foreach loop once it has found a string short enough to display, and the character list can be edited.

<?php
function word_limiter( $text, $limit = 30, $chars = '0123456789' ) {
    if( strlen( $text ) > $limit ) {
        $words = str_word_count( $text, 2, $chars );
        $words = array_reverse( $words, TRUE );
        foreach( $words as $length => $word ) {
            if( $length + strlen( $word ) >= $limit ) {
                array_shift( $words );
            } else {
                break;
            }
        }
        $words = array_reverse( $words );
        $text = implode( " ", $words ) . '&hellip;';
    }
    return $text;
}$str = "Hello this is a list of words that is too long";
echo '1: ' . word_limiter( $str );
$str = "Hello this is a list of words";
echo '2: ' . word_limiter( $str );
?>

1: Hello this is a list of words&hellip;
2: Hello this is a list of words

//To get the word count for any European language using a Roman alphabet:
$count = str_word_count($str, 0, 'äëïöüÄËÏÖÜáǽćéíĺńóŕśúźÁǼĆÉÍĹŃÓŔŚÚŹ'.
   'àèìòùÀÈÌÒÙãẽĩõñũÃẼĨÕÑŨâêîôûÂÊÎÔÛăĕğĭŏœ̆ŭĂĔĞĬŎŒ̆Ŭ'.

<?php

$characterMap = 'áéíóúüñ';
$count = str_word_count($text, 0, $characterMap);

?>

----------------------------------------------

<?php

function trim_text($text, $count){

$text = str_replace("  ", " ", $text);

$string = explode(" ", $text);

for ( $wordCounter = 0; $wordCounter <= $count;wordCounter++ ){

$trimed .= $string[$wordCounter];

if ( $wordCounter < $count ){ $trimed .= " "; }

else { $trimed .= "..."; }

}

$trimed = trim($trimed);

return $trimed;

}

?>



Usage

------------------------------------------------

<?php

$string = "one two three four";

echo trim_text($string, 3);

?>



returns:

one two three...

<?php

//count words

$words_to_count = strip_tags($body);

$pattern = "/[^(w|d|'|"|.|!|?|;|,|\|/|--|:|&|@)]+/";

$words_to_count = preg_replace ($pattern, " ", $words_to_count);

$words_to_count = trim($words_to_count);

$total_words = count(explode(" ",$words_to_count));

?>



Hope I didn't miss any punctuation. ;-)

<?php

function Truncate($input, $numWords)

{

  if(str_word_count($input,0)>$numWords)

  {

    $WordKey = str_word_count($input,1);

    $PosKey = str_word_count($input,2);

    reset($PosKey);

    foreach($WordKey as $key => &$value)

    {

        $value=key($PosKey);

        next($PosKey);

    }

    return substr($input,0,$WordKey[$numWords]);

  }

  else {return $input;}

}

?>



The idea behind it? Go through the keys of the arrays returned by str_word_count and associate the number of each word with its character position in the phrase. Then use substr to return everything up until the nth character. I have tested this function on rather large entries and it seems to be efficient enough that it does not bog down at all.

Cheers!

<?php

function num_words($string){

    preg_match_all("/S+/", $string, $matches);

    return count($matches[0]);

}

?>

<?php
function my_meta_description($text,$n=10)
{
$text=strip_tags($text);  // not neccssary for none HTML
// $text=strip_shortcodes($text); // uncomment only inside wordpress system
$text = trim(preg_replace("/s+/"," ",$text));
$word_array = explode(" ", $text);
if (count($word_array) <= $n)
return implode(" ",$word_array);
else
{
$text='';
foreach ($word_array as $length=>$word)
{
    $text.=$word ;
    if($length==$n) break;
    else $text.=" ";
}
}
return $text;
?>

In reality, I wanted a preview of the first hundred words of a blog entry which was well over that.

I found all of the other functions which explode and implode strings to arrays lost key markups such as line breaks etc.

So, this is what I came up with:

<?php

function WordTruncate($input, $numWords) {

if(str_word_count($input,0)>$numWords)

{

    $WordKey = str_word_count($input,1);

    $WordIndex = array_flip(str_word_count($input,2));

    return substr($input,0,$WordIndex[$WordKey[$numWords]]);

}

else {return $input;}

}

?>



While I haven't counted per se, it's accurate enough for my needs. It will also return the entire string if it's less than the specified number of words.

The idea behind it? Use str_word_count to identify the nth word, then use str_word_count to identify the position of that word within the string, then use substr to extract up to that position.

Josh.

<?php
function count_words($text) {
    $text = str_replace(str_split('|'), '', $text); // remove these chars (you can specify more)
    $text = trim(preg_replace('/s+/', ' ', $text)); // remove extra spaces
    $text = preg_replace('/-{2,}/', '', $text); // remove 2 or more dashes in a row
    $len = strlen($text);

        if (

0 === $len) {
        return 0;
    }$words = 1;

        while (

$len--) {
        if (' ' === $text[$len]) {
            ++$words;
        }
    }

        return

$words;
}
?>

it strips the pipe "|" chars, which antiword uses to format tables in its plain text output, removes more than one dashes in a row (also used in tables), then counts the words.

counting words using explode() and then count() is not a good idea for huge texts, because it uses much memory to store the text once more as an array. this is why i'm using while() { .. } to walk the string
