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); ?>
