Manual:Shell.php/ja

$file は、 ディレクトリにあるメンテナンス スクリプトであり、MediaWiki のオブジェクトや関数を試すために使用できます. It is based on PsySH; it replaces which is less robust and has fewer features.

Beyond the ability to evaluate PHP statements, functionality includes handling errors and fatals in a way that does not break the shell, examining object internals, source code and documentation via reflection, external editor integration and more.

Command execution and error handling

Editline integration
PsySH can integrate with readline / editline (PHP usually comes pre-built with the latter).
