title: Can a value from $_POST *not* be a string?
body: <p>In PHP, can a value from the global $_POST array be something else than an array or a string?</p>
  
  <p>The goal is to not have to check if everything is something else than an array or string in a script. If I know what type a variable has, I don't have to do some weird validation. If I expect a string, I don't have to cast everything to a string to make sure it is one.</p>
