Actually, the section "Determining variable types"[1] is even rather misleading.

Your will edit the form like as <form action="?" method="post"> or <form action="?" method="get"> test it again. ------------------------------------------------------------------------ [2017-06-09 11:34:09] requinix@php.net As the new summary says, values in $_GET and $_POST are strings. Well, strings or arrays. Naturally that is the same for $_REQUEST. And it's the case for $_COOKIE too. And even $_SERVER and $_ENV. Anyways, PHP will not try to determine integers or floats, and definitely will not interpret the string "null" to be literally NULL.
