title: Multiple $_GET from a link parameters
body: <p>I'm sending values to php file using js like that:</p>
  
  <pre><code>validation.php?firstName=test?lastName=test?email=test?contactNumber=test?title=test?description=test
  </code></pre>
  
  <p>And in validation.php I've created array with these values like that:</p>
  
  <pre><code>$data[0] = $_GET['firstName'];
  $data[1] = $_GET['lastName'];
  $data[2] = $_GET['email'];
  $data[3] = $_GET['contactNumber'];
  $data[4] = $_GET['title'];
  $data[5] = $_GET['description'];
  </code></pre>
  
  <p>unfortunately php returns me errors, why?</p>
