ERROR_REPORTING

Sets which PHP errors are reported

SYNTAX

error_reporting ([ int $level ] ) : int

PARAMETERS

level

The new error_reporting level. It takes on either a bitmask, or named constants. Using named constants is strongly encouraged to ensure compatibility for future versions. As error levels are added, the range of integers increases, so older integer-based error levels will not always behave as expected.

VALUE CONSTANT DESCRIPTION
1 E_ERROR 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 Run-time warnings (non-fatal 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. 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 Fatal errors that occur during PHP's initial startup. This is like an E_ERROR, except it is generated by the core of PHP.
32 E_CORE_WARNING 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.
64 E_COMPILE_ERROR Fatal compile-time errors. This is like an E_ERROR, except it is generated by the Zend Scripting Engine.
128 E_COMPILE_WARNING Compile-time warnings (non-fatal errors). This is like an E_WARNING, except it is generated by the Zend Scripting Engine.
256 E_USER_ERROR User-generated error message. This is like an E_ERROR, except it is generated in PHP code by using the PHP function trigger_error().
512 E_USER_WARNING User-generated warning message. This is like an E_WARNING, except it is generated in PHP code by using the PHP function trigger_error().
1024 E_USER_NOTICE User-generated notice message. This is like an E_NOTICE, except it is generated in PHP code by using the PHP function trigger_error().
2048 E_STRICT Enable to have PHP suggest changes to your code which will ensure the best interoperability and forward compatibility of your code.
4096 E_RECOVERABLE_ERROR Catchable fatal error. It indicates that a probably dangerous error occurred, 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.
8192 E_DEPRECATED Run-time notices. Enable this to receive warnings about code that will not work in future versions.
16384 E_USER_DEPRECATED User-generated warning message. This is like an E_DEPRECATED, except it is generated in PHP code by using the PHP function trigger_error().
32767 E_ALL All errors and warnings, as supported, except of level E_STRICT prior to PHP 5.4.0.

RETURN

Returns the old error_reporting level or the current level if no level parameter is given.
