php checking if empty fields

i have form submits 10 fields, , 7 of them should filled, here how chek in php:

if (!$name || !$phone || !$email || !$mobile || !$email || !$state || !$street || !  $city) {         echo '<div class="empty_p">you have empty fields!!!</div>';} else{         //process order or }

my question is: there more simple way this? because have more strings check (12-15)

<input type="text" name="required[first_name]" /> <input type="text" name="required[last_name]" /> ...   $required = $_post['required']; foreach ($required $req) {    $req = trim($req);    if (empty($req))       echo 'gotcha!'; }

/* update */

ok! guys, easy...

you can make more secure, type casting programmers out coming data, $id = (int) $_get['id'], $username = (string) addslashes($_post['username']) , on...;

$required = (array) $_post['required'];

and then, ever comes post fields let them come, code seek need. it! uhh...
