error_reporting
(PHP 3, PHP 4, PHP 5)
error_reporting -- Sets which PHP errors are reported
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.
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.

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 (bitwise 63 may be used in PHP 3)
error_reporting(E_ALL);
// Same as error_reporting(E_ALL);
ini_set('error_reporting', E_ALL);
?>

Notes
| 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.
