title: Form filling helper
body: <p>I want to program a "form filling helper" with PHP, which fills out forms on different websites, but does not send the form (it should be proved manually, if everything is correct).</p>
  
  <p>I read that cURL can fill out forms and send them, but I want to check them first, before they are sent.</p>
  
  <p>Is this possible in PHP?</p>
  
  <p>Thanks for suggestions!</p>
