Description

bool import_request_variables (string types [, string prefix])

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

useful if you disabled

register_globals,

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

extract().

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
error reporting
level.
