(PHP 4, PHP 5, PHP 7, PHP 8)
error_reporting — Sets which PHP errors are reported
$error_level = null): int
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. If the optional error_level is
not set, error_reporting() will just return
the current error reporting level.
error_levelThe 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 and the actual meanings of these error levels are described in the predefined constants.
Returns the old error_reporting
level or the current level if no error_level parameter is
given.

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
error_reporting(E_ALL & ~E_NOTICE);
// Report all PHP errors
error_reporting(E_ALL);
// Report all PHP errors
error_reporting(-1);
// Same as error_reporting(E_ALL);
ini_set('error_reporting', E_ALL);
?>
Passing in the value -1 will show every possible error,
even when new levels and constants are added in future PHP versions. The
behavior is equivalent to passing E_ALL constant.
