title: PHP: Maximum number of form (FILE) fields
body: <p>I want to upload 50 files at the same time (well, a clients wants this 'amazing feature'). However, PHP only processes the first 20 form fields; after that, they just do not exist for PHP.</p>
  
  <p>I've had this problem before but did not document properly how to solve it. I believe it's a PHP setting, but I can not find it.</p>
