PHP error level - error_reporting

The error_reporting directive in php.ini defines the levels of errors that PHP will report, the levels of errors are:

 

Errors and Logging
Value Constant Description Note
1 E_ERROR (integer) Fatal run-time errors. These indicate errors that can not be recovered from, such as a memory allocation problem. Execution of the script is halted.
2 E_WARNING (integer) Run-time warnings (non-fatal errors). Execution of the script is not halted.
4 E_PARSE (integer) Compile-time parse errors. Parse errors should only be generated by the parser.
8 E_NOTICE (integer) Run-time notices. Indicate that the script encountered something that could indicate an error, but could also happen in the normal course of running a script.
16 E_CORE_ERROR (integer) Fatal errors that occur during PHP's initial startup. This is like an E_ERROR, except it is generated by the core of PHP. since PHP 4
32 E_CORE_WARNING(integer) Warnings (non-fatal errors) that occur during PHP's initial startup. This is like an E_WARNING, except it is generated by the core of PHP. since PHP 4
64 E_COMPILE_ERROR(integer) Fatal compile-time errors. This is like an E_ERROR, except it is generated by the Zend Scripting Engine. since PHP 4
128 E_COMPILE_WARNING(integer) Compile-time warnings (non-fatal errors). This is like an E_WARNING, except it is generated by the Zend Scripting Engine. since PHP 4
256 E_USER_ERROR (integer) User-generated error message. This is like an E_ERROR, except it is generated in PHP code by using the PHP function trigger_error(). since PHP 4
512 E_USER_WARNING(integer) User-generated warning message. This is like an E_WARNING, except it is generated in PHP code by using the PHP functiontrigger_error(). since PHP 4
1024 E_USER_NOTICE (integer) User-generated notice message. This is like an E_NOTICE, except it is generated in PHP code by using the PHP function trigger_error(). since PHP 4

4096 E_RECOVERABLE_ERROR(integer) Catchable fatal error. It indicates that a probably dangerous error occured, but did not leave the Engine in an unstable state. If the error is not caught by a user defined handle (see also set_error_handler()), the application aborts as it was an E_ERROR. since PHP 5.2.0
