PHP Comment

When it comes to altering the case of a string, PHP makes it easy with four built-in functions. Two of them are illustrated previously: the strtoupper() function uppercases all the characters in a string, while the strtolower() function lowercases all the characters in a string.

For more precise control, consider the ucfirst() function, which capitalizes the first character of a string (good for sentences), and the ucwords() function, which capitalizes the first character of every word in the string (good for titles).

<?php
// define string
$rhyme = "and all the king's men couldn't put him together again";
// uppercase first character of string
// result: "And all the king's men couldn't put him together again"
$ucfstr = ucfirst($rhyme);
echo $ucfstr;
// uppercase first character of every word of string
// result: "And All The King's Men Couldn't Put Him Together Again"
$ucwstr = ucwords($rhyme);
echo $ucwstr;
?>
