Syntax

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

Parameter description:

• $types: Specify the variables to be imported, which can be represented by the letters G, P, and C for GET, POST, and Cookie, respectively. These letters are case-insensitive, so you can use any combination of g, p, and c. POST includes file information uploaded through the POST method. Note the order of these letters; when using gp, POST variables will overwrite GET variables with the same name. Any letter other than GPC will be ignored.

• $prefix: The prefix of the variable name, placed before all variables imported into the global scope. So if you have a GET variable named userid and provide pref_ as the prefix, you will get a global variable named $pref_userid. Although the prefix parameter is optional, if you do not specify a prefix or specify an empty string as the prefix, you will get an E_NOTICE level error.

Return value

None.

Online example

// Here GET and POST variables will be imported
// using w3codebox_ as prefix
import_request_variables("gP", "w"3codebox_);
echo $w3codebox_foo;
?>
