Manual:eval.php

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. It is now considered deprecated and has been replaced by shell.php which is more robust (does not abort on fatal errors) and has more features (auto-printing return values, reflection, documentation viewer, tab completion etc).

$ 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();
