error_reporting

Synopsis

int error_reporting([int level])

Sets the level of errors reported by PHP to level and returns the current level; if level is omitted, the current level of error reporting is returned. The following values are available for the function:

E_ERROR	Fatal runtime errors (script execution halts)
E_WARNING	Runtime warnings
E_PARSE	Compile-time parse errors
E_NOTICE	Runtime notices
E_CORE_ERROR	Errors generated internally by PHP
E_CORE_WARNING	Warnings generated internally by PHP
E_COMPILE_ERROR	Errors generated internally by the Zend scripting engine
E_COMPILE_WARNING	Warnings generated internally by the Zend scripting engine
E_USER_ERROR	Runtime errors generated by a call to trigger_error()
E_USER_WARNING	Runtime warnings generated by a call to trigger_error()
E_STRICT	Direct PHP to suggest code changes to assist with forward compatibility
E_RECOVERABLE_ERROR	If a potentially fatal error has occurred, was caught, and properly handled, the code can continue execution
E_DEPRECATED	If enabled, warnings will be issued about deprecated code that will eventually not work properly
E_USER_DEPRECATED	If enabled, any warning message triggered by deprecated code can be user-generated with the trigger_error() function
E_ALL	All of the above options

Any number of these options can be ORed (bitwise OR, |) together, so that errors in each of the levels are reported. For example, the following code turns off user errors and warnings, performs some actions, then restores the original level:

<$level = error_reporting ...
