title: PHP - check / compare input from textfield
body: <p>Until now I had a PHP Kontaktform with empty textfields and checked the needed fields with:</p>
  
  <p><code>$name = check_input($_POST['name'], "Please enter a Name.");</code></p>
  
  <p>Now the lable "your name" is in it the textfield itself. So the value is not empty anymore.
  How do I check if there's still only "your name" in the field instead of a real name?</p>
  
  <p>Thank you
  (sorry php-noob)</p>
