PHP: convert string to uppercase / capitals

PHP provides a simple function to convert all letters to uppercase / captials: strtoupper();

code snippet:


<?php

$str = "Mary Had A Little Lamb and She LOVED It So";

$str = strtoupper($str);

echo $str;

?>

sample output:

MARY HAD A LITTLE LAMB AND SHE LOVED IT SO

notes:

see also strtolower() for the opposite effect (convert to lower case).
