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:
1. Set the error reporting level
<?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); ?>
These options will tell PHP to display different levels of errors. For example, if you set error_reporting() to E_ALL, PHP will display all errors, including warnings, fatal errors, etc.
2. Modify the INI settings at runtime
<?php // 显示所有错误 ini_set('display_errors', 1); // 隐藏所有错误 ini_set('display_errors', 0); ?>
By calling the ini_set() function and setting the first parameter to display_errors, the second parameter is the specific value of the setting ( 0=hide, 1=show).
Combining these two features, you can implement the following in your code:
<?php // 显示所有错误 error_reporting(E_ALL); ini_set('display_errors', 1); ?> <!DOCTYPE html> <html> <head> <title>Error Reporting Example</title> </head> <body> <?php // Your PHP code here ?> </body> </html>
In this example, PHP will display all errors and set display_errors to 1 so that An error message is output to the browser.
