<?
$mixed_case_word = "Lower Case and Upper Case";

Initial-capping words is a very common task
<?php
$first_name = "jeremy";
$last_name = "allen";
$middle_init = "w";
$first_name = ucfirst($first_name);
$last_name = ucfirst($last_name);
$middle_init = ucfirst($middle_init);
print("$first_name $middle_init $last_name<br />");
$name = "jeremy w allen";
$name = ucwords($name);
print($name . "<br />");
?>
