Simplification de code de traitement de données formulaire

Bonjour,

Comment pourrais-je simplifier au maximum ce code :

$nom = addslashes(mysql_real_escape_string(htmlentities(trim($_POST'inputNom']))));
        $prenom = addslashes(mysql_real_escape_string(htmlentities(trim($_POST'inputPrenom']))));
        $email = addslashes(mysql_real_escape_string(htmlentities(trim($_POST'inputEmail']))));
        $tel = addslashes(mysql_real_escape_string(htmlentities(trim($_POST'inputTel']))));
        $sexe = addslashes(mysql_real_escape_string(htmlentities(trim($_POST'sexe']))));
        $moncas = addslashes(mysql_real_escape_string(htmlentities(trim($_POST'monCas']))));       
        $origine = addslashes(mysql_real_escape_string(htmlentities(trim($_POST'PaysOrigine']))));
        $jnaiss = addslashes(mysql_real_escape_string(htmlentities(trim($_POST'jnaiss']))));
        $mnaiss = addslashes(mysql_real_escape_string(htmlentities(trim($_POST'mnaiss']))));
        $anaiss = addslashes(mysql_real_escape_string(htmlentities(trim($_POST'anaiss']))));        
        $jrdv = addslashes(mysql_real_escape_string(htmlentities(trim($_POST'jrdv']))));
        $mrdv = addslashes(mysql_real_escape_string(htmlentities(trim($_POST'mrdv']))));
        $ardv = addslashes(mysql_real_escape_string(htmlentities(trim($_POST'ardv']))));
        $heure = addslashes(mysql_real_escape_string(htmlentities(trim($_POST'hrdv']))));
        $minute = addslashes(mysql_real_escape_string(htmlentities(trim($_POST'minrdv']))));
        $nomfichier = addslashes(mysql_real_escape_string(htmlentities(trim($_FILES'photo_client']'name']))));
        $nomphotoclient = addslashes(mysql_real_escape_string(htmlentities(trim($_POST'nom_photo_client']))));

Avec une boucle peut être ou en créant une fonction ?
