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	Runtime warnings
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_ALL	All of the above options

Any number of these options can be ORed (bit-wise 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:

<?php
 $level = error_reporting(  );
 error_reporting($level & ~(E_USER_ERROR | E_USER_WARNING));
 // do some stuff
 error_reporting($level);
?>
