# error_reporting

(PHP 4, PHP 5)

error_reporting — Sets which PHP errors are reported

### Описание

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.

### Список параметров

`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.

### Примеры

Пример #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);
?>`

### Примечания

Внимание

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).
