import_request_variables - Import GET/POST/Cookie variables into the global scope

SYNOPSIS
       bool import_request_variables (string  $types, [string  $prefix])

DESCRIPTION
	Imports  GET/POST/Cookie  variables into the global scope. It is useful if you disabled register_globals, but would like to see some vari-
       ables in the global scope.

	If you're interested in importing other variables into the global scope, such as $_SERVER, consider using extract(3).

       Warning

	      This function has been DEPRECATED as of PHP 5.3.0 and REMOVED as of PHP 5.4.0.

PARAMETERS
	      o $types
		- Using the $types parameter, you can specify which request variables to import. You can use 'G', 'P' and 'C'  characters  respec-
		tively for GET, POST and Cookie. These characters are not case sensitive, so you can also use any combination of 'g', 'p' and 'c'.
		POST includes the POST uploaded file information.

	      Note

		      Note that the order of the letters matters, as when using " GP", the POST variables will overwrite GET  variables  with  the
		     same name. Any other letters than GPC are discarded.

	      o $prefix
		-  Variable  name  prefix, prepended before all variable's name imported into the global scope. So if you have a GET value named "
		userid", and provide a prefix " pref_", then you'll get a global variable named $pref_userid.

	      Note

		      Although the $prefix parameter is optional, you will get an E_NOTICE level error if you specify no  prefix,  or  specify	an
		     empty  string  as a prefix. This is a possible security hazard. Notice level errors are not displayed using the default error
		     reporting level.

RETURN VALUES
	Returns TRUE on success or FALSE on failure.
