How can I change letters or words from small letters to capital letters?

[zamzam]

I am asking for a PHP code that can be used to change letters or words from small letters to capital letters? Please help

[logic_earth]

Read the manual much? http://us3.php.net/manual/en/function.strtoupper.php

Use strtoupper function. like this

<?php
$str = "Mary Had A Little Lamb and She LOVED It So";
$str = strtoupper($str);
echo $str; // Prints MARY HAD A LITTLE LAMB AND SHE LOVED IT SO
?>
