PHP Text Flipper Library

Have you seen some cool webapps where you can write English texts upside down?

I have found out the techniques. They just use some Unicode characters to do the trick. Unicode has a vast collection of characters and you have to find the right one that looks like an upside down english character.

I have written a PHP library to do the job .
Visit the demo at:

Download the Library at:
http://masnun.googlecode.com/files/flipper.php 🙂

Here’s the source code of the demo:

<?php
header("Content-type: text/html; charset='utf-8'");
echo "<html><head>
<meta http-equiv=\"Content-Type\" content=\"text/html; charset=utf-8\">
<title>maSnun's string flipper</title><body>
<form action=\"index.php\" method=\"POST\">
<b>Enter a string:</b><br />
<input type=\"text\" name=\"string\" value=\"{$_POST['string']}\">
<input type=\"submit\" value=\"flipNow()\">
</form><br /><br />";

if(isset($_POST['string'])) {
include('flipper.php');
$stringFlipper = new StringFlipper;
$str = $stringFlipper->flipString($_POST['string']);
echo "<b>Flipped String:</b><input type=\"text\" value=\"$str\"> <br /><br />";

}

echo "</body><html>";

?>

<?php

header("Content-type: text/html; charset='utf-8'");

echo "<html><head>

<title>maSnun's string flipper</title><body>

<b>Enter a string:</b><br />

</form><br /><br />";

if(isset($_POST['string'])) {

include('flipper.php');

$stringFlipper = new StringFlipper;

$str = $stringFlipper->flipString($_POST['string']);

echo "<b>Flipped String:</b><input type=\"text\" value=\"$str\"> <br /><br />";

}

echo "</body><html>";

PS: PHP and web browsers have some issues regarding Unicode data. So please ensure the “Content-type” is set to “text/html” and the charset is “utf-8” 🙂

Happy flipping 😀
