The operating system of this tutorial: Windows 10 system, phpcms v9 version, Dell G3 computer.

To display error information in phpcms, you can use PHP's built-in `error_reporting()` and `ini_set()` functions.

The following is a sample code that displays all error messages:

<?php
// 显示所有错误
error_reporting(E_ALL);
// 除了提示级别之外的所有错误
error_reporting(E_ALL & ~E_NOTICE);
// 关闭所有错误报告
error_reporting(0);
?>

<?php
// 显示所有错误
ini_set(&#39;display_errors&#39;, 1);
// 隐藏所有错误
ini_set(&#39;display_errors&#39;, 0);
?>

<?php
// 显示所有错误
error_reporting(E_ALL);
ini_set(&#39;display_errors&#39;, 1);
?>
