[RESOLVED] How to change this code to a simple loop with different variables

[elemelas]

Hi guys,

Have a good few lines of the code, which I would like to throw in to the loop, instead of doing it all manually. I'm not sure how to do it with the changeable variables though. Should I use an array for different variable names? Does anyone have an idea?

if(isset($_POST['contact_name'])) { $contact_name = htmlentities($_POST['contact_name']); } else { $contact_name = ''; }
if(isset($_POST['contact_phone'])) { $contact_phone = htmlentities($_POST['contact_phone']); } else { $contact_phone = ''; }
if(isset($_POST['email'])) { $email = htmlentities($_POST['email']); } else { $email = ''; }

$postKeys = array('key1', 'key2', 'key3');
foreach($postKeys as $key) {
  // do something with $_POST[$key]
}

Thanks for your reply NogDog,

The bigger problem than feeding an array into the loop is to assign the variables though. Here is what I have so far (not working though)

$postKeys = array('contact_name','contact_number','email');
foreach($postKeys as $key) {
$variable = "$'$key'";
if(isset($_POST["$key"])) { 
$variable = htmlentities($_POST["$key"]);
}
else {
$variable = '';
}
}

Try using just $$key (no need for $variable at all).
