PHP Error Reporting Calculator
In PHP, error reporting controls how PHP handles and displays errors and warnings during code execution. The error reporting level determines the severity of errors that will be displayed.
You can set the error reporting level using the error_reporting function or by modifying the error_reporting PHP configuration directive in a .ini file.
The error_reporting function accepts an error level which can be specified using predefined error constants or by combining them using the bitwise OR operator (|).
For example, to display all errors and warnings, you can use:
error_reporting(E_ALL);
This sets the error reporting level to include E_ERROR, E_WARNING, E_PARSE, E_NOTICE, and other error types.
You can also explicitly exclude certain error levels by using the bitwise NOT operator (~). For example, to exclude the E_NOTICE errors, you can use:
error_reporting(E_ALL & ~E_NOTICE);
This sets the error reporting level to include all errors and warnings except E_NOTICE.
Additionally, you can set different error reporting levels for different parts of your PHP code by using the error_reporting function at different points in your script.
It is important to note that error reporting configuration affects the display of errors on the website, but it does not affect the way errors are logged. Logging of errors is controlled separately through the log_errors and error_log directives.
