How to use the php error_reporting() function?
The error_reporting() function sets the error reporting level of the current script and specifies what kind of PHP errors are reported.
This function can set 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 level argument is not set, error_reporting() simply returns the current error reporting level.
Syntax
error_reporting(report_level)
Parameters:
● 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 range of integer values, 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.
Reporting level
Return value: Return the old error reporting (error_reporting) level, or in Returns the current level when the level argument is not given.
Let’s take a look at how to use the php error_reporting() function through an example.
Example:Specify different error level reporting
<?php // 关闭错误报告 error_reporting(0); // 报告 runtime 错误 error_reporting(E_ERROR | E_WARNING | E_PARSE); // 报告所有错误 error_reporting(E_ALL); // 等同 error_reporting(E_ALL); ini_set("error_reporting", E_ALL); // 报告 E_NOTICE 之外的所有错误 error_reporting(E_ALL & ~E_NOTICE); ?>
