eval.php is a maintenance script that is located in the maintenance directory that you can use to play live with MediaWiki objects and functions.

$ php maintenance/eval.php
> print wfMessage("Recentchanges")->plain();
Recent changes

MediaWiki classes are automatically autoloaded:

$ php maintenance/eval.php
> echo Xml::label( 'My label', 'someInput', array( 'class' => 'pink' ) );
<label for="someInput" class="pink">My label</label>

Some debugging is also possible:

$ php  maintenance/eval.php --d 3
> print wfMessage("Recentchanges")->text();
