In PHP, a superglobal is a built-in variable that always available in all scopes.

Description

Several predefined variables in PHP are "superglobals", which means they are available in all scopes throughout a script.

These superglobal variables are:

  • $GLOBALS
  • $_SERVER
  • $_GET
  • $_POST
  • $_FILES
  • $_COOKIE
  • $_SESSION
  • $_REQUEST
  • $_ENV
