手册:Eval.php

MediaWiki文件： eval.php
位置：	maintenance/
源代码：	master • 1.41.1 • 1.40.3 • 1.39.7
类：	查找代码 • 查找帮助文档

eval.php是位于maintenance目录中的维护脚本，您可以使用该文件实时播放MediaWiki对象和功能。 现在认为它已被弃用，并已由shell.php 取代，它更可靠（不会因致命错误而中止），并具有更多功能（自动打印返回值，反射，文档查看器，制表符补全，等等）。

$ 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>

也可以进行一些调试：

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