Manual:WebRequest.php

Details
The WebRequest class which encapsulates getting at data passed in the URL or via a POSTed form, handling remove of "magic quotes" slashes, stripping illegal input characters and normalizing Unicode sequences.

You can access the standard WebRequest through .

You should not create additional instances of this class.

Instead create a DerivativeRequest or use FauxRequest if there is no user request context.

Functions

 * - get a string, or null if the parameter was not set.
 * - get an integer, or null if the parameter was not set.
 * - same as getVal, but [https://php.net/language.types.boolean#language.types.boolean.casting converts] the value to a boolean. To know if a parameter is set, use   instead.
 * - get an array or null if the parameter was not passed. If the parameter is a scalar, it will return an array with a single element.
 * - return a boolean whether the parameter was passed, this is useful for checkboxes.

WebRequestUpload
WebRequestUpload is an object to access the [https://php.net/reserved.variables.files $_FILES] array. It should only be called by WebRequest. A WebRequestUpload object is generated by WebRequest::getUpload.

FauxRequest
FauxRequest is a class extending WebRequest. Its purpose is to emulate a request for testing or prototyping. FauxRequest should be avoided in production code.
