Clean up POST und GET

Zusätzliche Sicherheit für Post und Get.

function clean($elem) {
	/* used to add some security to get and post vars */
	if(!is_array($elem)) 
		$elem = htmlentities($elem,ENT_QUOTES,"UTF-8"); 
    	else 
		foreach ($elem as $key => $value) 
			$elem[$key] = $this->clean($value); 
    	return $elem; 
} 

$_CLEAN['GET'] = clean($_GET); 
$_CLEAN['POST'] = clean($_POST);

IP Adresse Abfragen

		public static function get_ip() {
			$REMOTE_ADDR = $_SERVER['REMOTE_ADDR'];
			if ( ! empty( $_SERVER['X_FORWARDED_FOR'] ) ) {
				$X_FORWARDED_FOR = explode(',', $_SERVER['X_FORWARDED_FOR'] );
				if ( ! empty( $X_FORWARDED_FOR ) ) {
					$REMOTE_ADDR = trim( $X_FORWARDED_FOR[0] );
				}
			}
			elseif ( ! empty($_SERVER['HTTP_X_FORWARDED_FOR'] ) ) {

				if ( ! empty($HTTP_X_FORWARDED_FOR ) ) {
					$REMOTE_ADDR = trim($HTTP_X_FORWARDED_FOR[0]);
				}
			}
			return preg_replace('/[^0-9a-f:\., ]/si', '', $REMOTE_ADDR);
