## Definition and Usage

The error_reporting() function specifies which errors are reported.

This function sets which errors are reported for the duration of the current script.

This funtion returns the old error_reporting level.

## Syntax

error_reporting(report_level)

Parameter | Description
--- | ---
report_level | Optional. Specifies the error report level for the current script. Value number and constant name are accepted, however, constant names are recommended for compatibility for future PHP versions

## Report levels

Value | Constant | Description
--- | --- | ---
1 | E_ERROR | Fatal run-time errors. Errors that can not be recovered from. Execution of the script is halted
2 | E_WARNING | Non-fatal run-time errors. Execution of the script is not halted
4 | E_PARSE | Compile-time parse errors. Parse errors should only be generated by the parser
8 | E_NOTICE | Run-time notices. The script found something that might be an error, but could also happen when running a script normally
16 | E_CORE_ERROR | Fatal errors at PHP startup. This is like an E_ERROR in the PHP core
32 | E_CORE_WARNING | Non-fatal errors at PHP startup. This is like an E_WARNING in the PHP core
64 | E_COMPILE_ERROR | Fatal compile-time errors. This is like an E_ERROR generated by the Zend Scripting Engine
128 | E_COMPILE_WARNING | Non-fatal compile-time errors. This is like an E_WARNING generated by the Zend Scripting Engine
256 | E_USER_ERROR | Fatal user-generated error. This is like an E_ERROR set by the programmer using the PHP function trigger_error()

1024 | E_USER_NOTICE | User-generated notice. This is like an E_NOTICE set by the programmer using the PHP function trigger_error()
2048 | E_STRICT | Run-time notices. PHP suggest changes to your code to help interoperability and compatibility of the code
4096 | E_RECOVERABLE_ERROR | Catchable fatal error. This is like an E_ERROR but can be caught by a user defined handle (see also set_error_handler())
8191 | E_ALL | All errors and warnings, except level E_STRICT (E_STRICT will be part of E_ALL as of PHP 6.0)
