PHP: Capture the requested URI and Clean up global variables

<?php

$requestURI = 'http://'.$_SERVER['SERVER_NAME'].$_SERVER['REQUEST_URI']';

echo $requestURI;

?>

This snippet is more of an example of how to convert strings to lowercase characters, and then clean them up for use in scripts, etc

<?php

$_POST["name"] = strtolower(stripslashes(trim(htmlspecialchars($_POST["name"])))); $_POST["message"] = strtolower(stripslashes(trim(htmlspecialchars($_POST["message"]))));

?>
