import_request_variables -- Import GET/POST/Cookie variables into the global scopeImports 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 uploaded file informations. Note, that the order of the letters matters, as using "gp", the POST variables will overwrite GET variables with the same name. Any other other letters then GPC are discarded.
Note: Although the prefix argument is optional, you will get a 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.
// This will import GET and POST vars
// with an "rvar_" prefix
import_request_variables("gP", "rvar_"); |
