Usage and examples of php error_reporting() function

error_reporting() FunctionKneel down and tell you what kind of PHP error should be reported. This function enables setting the error_reporting directive at runtime.

PHP has many error levels. Use this function to set the level when the script is running. If the optional parameter level is not set, error_reporting() will only return the current error reporting level.

Syntax

error_reporting(level);

Parameters

Description

level

Optional. Specifies the new error_reporting level. Can be a bitmask or a named constant. Note: It is strongly recommended to use named constants to ensure compatibility with future versions. Due to the addition of error levels and the increase in the integervalue range, older integer-based error levels will not always behave as expected. The available error level constants and their actual meanings are described in predefined constants.

Example:
Any number of the above options can be connected with "OR" (using OR or |), so that all required options can be reported Wrong level.
For example, the following code turns off user-defined errors and warnings, performs certain operations, and then returns to the original error level:

<?php
//禁用错误报告
error_reporting(0);
 
//报告运行时错误
error_reporting(E_ERROR | E_WARNING | E_PARSE);
 
//报告所有错误
error_reporting(E_ALL);
?>
