PHP checking if empty fields

I have form that submits 10 fields, and 7 of them should be filled, here is how i chek it now 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 do something
}

My question is: is there more simple way to do this? Because sometimes I have even more strings to check (12-15)

Answer 1

<input type="text" name="required[first_name]" />
<input type="text" name="required[last_name]" />
...


$required = $_POST['required'];
foreach ($required as $req) {
   $req = trim($req);
   if (empty($req))
      echo 'gotcha!';
}

/* update */

OK! guys, easy…

You can make it more secure, just with type casting as all we programmers do for out coming data, like $id = (int) $_GET['id'], like $username = (string) addslashes($_POST['username']) and so on…;

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

And then, what ever comes from post fields let them come, this code just seek what it need.
That is it! Uhh…
