Here's a simple function I wrote for parsing form data.

It checks if it's an array and it is recursive (it calls itself).

It also decodes things that have already been encoded so it doesn't change & to &

<?php

function formspecialchars($var)
	{
		if (is_array($var)) {
			$out = array();
			foreach ($var as $key => $v) {
				$out[$key] = formspecialchars($v);
			}
		} else {
			$out = htmlspecialchars_decode($var);
			$out = htmlspecialchars(stripslashes(trim($out)), ENT_QUOTES);
		}
		
		return $out;
	}

?>

I encourage people to improve upon this for other purposes! All I use it for is cleaning up form data, hence the name of the function.
