2 e_warning Run-time warning (non-fatal error). Non-fatal run error, script execution does not stop.
4 E_parse Compile-time parse error. Parsing errors are generated only by the parser.
8 E_notice Runtime reminders, which are often caused by bugs in your code, or by intentional behavior.
E_core_error a fatal error during initialization of PHP startup.
e_core_warning PHP Startup warning (non-fatal error) during initialization.
E_compile_error compile-time fatal error. This is like a e_error generated by the Zend scripting engine.

E_user_notice user-defined reminder messages. This is like a standardized warning by using the PHP function Trigger_error (programmer a E_notice set)
2048 e_strict encoding. Allows PHP to suggest how to modify the code to ensure the best interoperability forward compatibility.
4096 e_recoverable_error to catch fatal error. This is like a e_error, but can be captured through user-defined processing (see also Set_error_handler ())
8191 E_all all errors and warnings (excluding e_strict) (E_strict will is part of E_all As of PHP 6.0)

disabling error Reporting
error_reporting (0);

Report Run-time errors
Error_reporting (E_error | e_warning | E_parse);

Report All Errors
Error_reporting (E_all);
