Manual:$wgRequest

$wgRequest is used as a global singleton that contains an instance of the WebRequest class. The WebRequest class encapsulates getting at data passed in the URL or via a POSTed form, handling removal of "magic quotes" slashes, stripping illegal input characters and normalizing Unicode sequences. See the WebRequest class documentation and Manual:WebRequest.php for more details.

This code can be useful within hook functions when you want to return without executing additional function code if the user is editing, rather than viewing, the current page.

global $wgRequest;
if ( $wgRequest->getText( 'action' ) == 'edit' ) {
	return true;
}

As with other globals, the use of $wgRequest should be avoided when alternative methods are available. For example, when writing a special page, use the getRequest() method provided by the SpecialPage class, e.g.:

$request = $this->getRequest();

When you work with various hooks you can usually get the WebRequest object from the context, for example:

$output->getRequest(); // here $output is an object of OutputPage class
$article->getContext()->getRequest(); // getting WebRequest from the Article object
$editpage->getArticle()->getContext()->getRequest(); // getting WebRequest from the EditPage object

In a special page context, one can use $this->getRequest().

In an API module context, one can use $this->getMain()->getRequest().
