Description
int
error_reporting ( [int level] )
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.
error_reporting() sets PHP's error reporting level,
and returns the old level. The level parameter
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.
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 (bitwise 63 may be used in PHP 3)
error_reporting(E_ALL);
// Same as error_reporting(E_ALL);
ini_set('error_reporting', E_ALL);
?>

The available error level constants are listed below. The actual
meanings of these error levels are described in the
predefined constants.

| Warning |
With PHP > 5.0.0 E_STRICT with value 2048 is
available. E_ALL does NOT
include error level E_STRICT.
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.

directive and ini_set().
