Reversing letters in word

Use this text reverser to quickly reverse text online. This free generator tool can also convert your text message into a backwards text version of your words.

This reverse text generator will take a word like «reverse» for example and change the letter order so that it now reads «esrever».

This is also a mirror mode option where the letters are mirror backwards versions of themselves but can also be put in reverse order. So for example, the word «MIRROR», would now look like «MIЯЯOЯ» when the mirror text option is chosen. It’s like you’re writing backward.

You can now copy and paste the text from this converter for use on Twitter, Instagram, or wherever the fun is.

Reverse Text Tool

I’ve made some revisions to this backwards text generator so it generally functions faster and better. I hope it works well for you.

An Interesting Fact about Backwards Text

Leonardo Da Vinci wrote backwards in what people call mirror writing style. Mirror writing is when the letters are not just in reverse order so that you have to read them backward but the orientation of each letter is also changed.

This backward writing can easily be deciphered by looking at it in a mirror. It’s similar to the way the word ambulance becomes legible if you see the word written on a vehicle in your rear-view mirror.

It’s been postulated that Da Vinci wrote in reverse not to hide his written ideas from people as there are far better ways for him to encode his work but to prevent him from smudging his notes.

The main theory right now is that, as a left-hander, Da Vinci found writing backward was the most efficient way to avoid smearing his notes. Plus it made him seem cool and who doesn’t want to seem cool?

For anyone with contrived limitations on the use of sensible native PHP functions

I’ll offer a snippet which leverages only for(), strlen(), and strpos(). My snippet assumes that the input string will:

• not have leading or trailing spaces, and
• have its «words» delimited by a single space, and
• be comprised exclusively of single-byte characters

Code: (Demo)

$string = "I am a boy like desired and expected";

for (
    $offset = 0, $length = strlen($string);
    $offset < $length;
    ++$offset
) {
    $offset += $string[$offset] === ' ';
    for (
        $swaps = 0, $wordEnd = (strpos($string, ' ', $offset) ?: $length) - 1;
        $offset < $wordEnd;
        ++$swaps, ++$offset, --$wordEnd
    ) {
        [$string[$wordEnd], $string[$offset]] = [$string[$offset], $string[$wordEnd]];
    }
    $offset += $swaps;
}
echo $string;

Output:

I ma a yob ekil derised dna detcepxe

This nested looping approach only calls strpos() once per word in the input text. It works by swapping the first letter with the last letter, then (as many times as needed) it «steps in» one position from the front and end, and swaps the next pair of letters. For example, like becomes eikl then ekil.

The character «swapping» syntax is call «array destructuring» (from PHP7.1). On the right side of the =, the variables to be swapped are declared as a two-element array. On the left side of the =, two-element array syntax is used again, but this time the values from the right side will be written into the variables on the left side. This technique avoids the need for a temporary variable to be declared.

Before entering the nested for() block, $offset += $string[$offset] === ' '; is called as an optimization to avoid unnecessary strpos() calls on a delimiting space (non-word character). When the nested for() block resolves, the offset is increased based on the number of swaps executed ($offset += $swaps;) — this keeps the offset integer moving forward and prevents an infinite loop.

This snippet was built with a focus not on brevity or readability, but on minimizing total function calls and computational time while avoiding temporary reversed substrings and concatenation. strlen() is only called once and strpos() is called once for every word in the input text.

This snippet is absolutely a purely academic endeavor and I would never put this in a professional application. The contrived limitations imposed will only be encountered in development challenges such as job interviews.

Maintaining a temporary reversed substring and conditionally concatenating offers a far more readable snippet with no iterated function calls as demonstrated by @thetaiko.

Code: (Demo)

$string = "I am a boy like desired and expected";

$result = '';
$reversedWord = '';
$length = strlen($string);
for ($offset = 0; $offset < $length; ++$offset) {
    if ($string[$offset] === ' ') {
        $result .= $reversedWord . ' ';
        $reversedWord = '';
    } else {
        $reversedWord = $string[$offset] . $reversedWord;
    }   
}
$result .= $reversedWord;
echo $string;

While processing consecutive non-whitespace characters, store them in as a temporary string variable — prepending each newly encountered character to the variable effectively reverses the word. Whenever a space is encountered, concatenate the temporary variable to the result string along with the delimiting space; then empty the temporary variable so that it can be used again. After the loop resolves, append any remaining temporary string to the result.

If you regularly use Microsoft Word with a language that reads from right-to-left, you may find that the right-to-left format remains when you try to write in English. This is because the text direction defaults to right-to-left in versions of Microsoft Word sold in some regions.

Luckily, if you’re using a Windows computer, changing the direction of text is easy via the “left-to-right” command. Only the most recent versions of Word for Mac support this feature, so if you encounter this problem, the best option is to copy and paste the text into a new document.

Customizing the Quick Access Toolbar

The first thing you need to do is add the “left-to-right” command to the Quick Access Toolbar. To do this, click the arrow next to the “Redo” button and choose “More Commands” from the dropdown list.

On the next screen, you have the option to choose commands to add to the toolbar. If you can’t see the “left-to-right” command, chose “All Commands” from the top menu.

Next, scroll down and choose “Left-to-Right Text Direction.” The name of the command here may depend on the version of Word you’re using. In Word 2010, this command is called “Ltr run,” while Word 2003 lists it as “Ltr para.”

Now the button will be displayed on the toolbar (you can use a similar process to add it to the main ribbon if you right click on the ribbon and select “Customize the Ribbon”).

Now select the text that is showing right-to-left, click the button, and it should switch to left-to-right. Repeat this last step anywhere in your document, including footnotes and comment boxes, where the text direction displays from right-to-left.

It’s also worth noting that you can select the “Right-to-Left Text Direction” command using the same method. This is useful if you need to switch back to the original format at any point.

Reversing Your Text

This is a simple translator I made that simply reverses your words or phrases. Note that you may be looking for a translator which mirrors your text (oƨ ɘʞil) — if so, click that link.

The way it does it is quite simple. Since you’re viewing this online in your browser, JavaScript is used as follows:

> «my example text».split(«»).reverse().join(«»);

The letters of the string are first split into individual array components, then the handy «String.reverse()» method is used, then we join the elements back up into a string, resulting in the same characters, but i a reverse or backwards direction.

Reverse Words

Writing text backwards is a great way to add a very light layer of cryptography to the things you write — reverse the word and character order, and make it slightly messy, and you may find that no one can understand it at all! You can also make other rules like leaving out the last vowel or something like that to make it harder.

A few quick examples of what this translator produces:

• yellow = wolley
• dog = god
• sheep = peehs
• park = krap
• racecar = racecar
• supercallifragilisticexpiallidocious = suoicodillaipxecitsiligarfillacrepus

Try reverse a word or phrase and post it in the comments below

I hope this little online tool helps you with whatever you’re doing. If you’ve got any suggestions for how I could improve this translator please let me know by putting them in the suggestions form. Thanks!
