This simple function will add st, nd, rd or th to a cardinal number (the suffix acts as an ordinal indicator). There are plenty of these functions floating around but only a few take the subtle variances into consideration that can screw up the result.
If you're using PHP 5 >= 5.3.0 and you have PECL intl >= 1.0.0 installed, consider PHP's class.numberformatter
.

return $cardinal . $extension;

Usage
To append the appropriate suffix to the ordinal number, use the following:
The resulting cardinal number will print as 14th.
If you would like to test the code, use the following loop that'll print the 1st through to the 99th.
