error_reporting
(PHP 4, PHP 5)
error_reporting — Sets which PHP errors are reported
Description
The error_reporting() function sets the error_reporting directive at runtime. PHP has many levels of errors, using this function sets that level for the duration (runtime) of your script.
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.
The available error level constants are listed below. The actual meanings of these error levels are described in the predefined constants.
error_reporting() level constants and bit values value constant 1 E_ERROR 2 E_WARNING 4 E_PARSE 8 E_NOTICE 16 E_CORE_ERROR 32 E_CORE_WARNING 64 E_COMPILE_ERROR 128 E_COMPILE_WARNING 256 E_USER_ERROR 512 E_USER_WARNING 1024 E_USER_NOTICE 6143 E_ALL 2048 E_STRICT 4096 E_RECOVERABLE_ERROR
Return Values
Returns the old error_reporting level.

Examples
Example #1 error_reporting() examples
<?php
// Turn off all error reporting
error_reporting(0);
// Report simple running errors
error_reporting(E_ERROR | E_WARNING | E_PARSE);
// Reporting E_NOTICE can be good too (to report uninitialized
// variables or catch variable name misspellings ...)
error_reporting(E_ERROR | E_WARNING | E_PARSE | E_NOTICE);
// Report all errors except E_NOTICE
// This is the default value set in php.ini
error_reporting(E_ALL ^ E_NOTICE);
// Report all PHP errors
error_reporting(E_ALL);
// Same as error_reporting(E_ALL);
ini_set('error_reporting', E_ALL);
?>
Notes
Most of E_STRICT errors are evaluated at the compile time thus such errors are not reported in the file where error_reporting is enhanced to include E_STRICT errors (and vice versa).
