PHP error_reporting: Purpose and Usage Guide

The error_reporting function in PHP is used to specify the level of error reporting during script execution. By setting different error reporting levels, you can control whether PHP displays and logs error messages during runtime.

The error_reporting function can take an integer parameter representing different levels of error reporting. Common error reporting levels include the following:

1. E_ALL: Display and log all error and warning messages.
2. E_ERROR: Only display and log fatal errors (such as syntax errors).
3. E_WARNING: Only displays and logs warning errors.
4. E_NOTICE: only displays and logs notice messages.

By using the error_reporting function, you can control the level of error message display and logging according to specific needs, making it easier to debug and handle errors.
