import_request_variables

(PHP 4 >= 4.1.0, PHP 5)import_request_variables -- Import GET/POST/Cookie variables into the global scope

bool import_request_variables (string types [, string prefix])

Imports GET/POST/Cookie variables into the global scope. It is

useful if you disabled

but would like to see some variables in the global scope.

Using the types parameter, you can

specify which request variables to import. You can use

'G', 'P' and 'C' characters respectively 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 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.

The prefix parameter is used as a 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.

If you're interested in importing other variables

into the global scope, such as SERVER, consider using

Замечание:

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

level.


<?php
// This will import GET and POST vars
// with an "rvar_" prefix
import_request_variables("gP", "rvar_");

echo $rvar_foo;
?>
