Another funny class with no serious use. This is a class I wrote to determine the numerical positions of letters in the English alphabet.
How to use ?

<?php include('alphabet.php'); $a = new alphabet(); // construct the alphabet object echo $a->getNum('z'); // outputs 26 echo $a->getChar(3); // outputs 'c' ?> |
As you can see, using the getNum() method, you can feed a letter and get the serial number or numerical position of that letter. Again in the same way, use the getChar() method to input a number and get the character/letter in that position.
I use it very often while breaking alphabet related codes.
