// This function is used to clean POST variables.	
function clean($value) {

	// If magic quotes not turned on add slashes.
	if(!get_magic_quotes_gpc())
	
	// Adds the slashes.
	{ $value = addslashes($value); }
	
	// Strip any tags from the value.
	$value = strip_tags($value);
	
	// Return the value out of the function.
	return $value;
