error_reporting
(PHP 4, PHP 5, PHP 7)
error_reporting — Sets which PHP errors are reported
Description
error_reporting
([ int $level
] ) : 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 level
is
not set, error_reporting() will just return
the current error reporting level.
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 and the actual meanings of these error levels are described in the predefined constants.
Return Values
Returns the old error_reporting
level or the current level if no level
parameter is
given.
Examples
Example #1 error_reporting() examples
<?php// Turn off all error reportingerror_reporting(0);// Report simple running errorserror_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_NOTICEerror_reporting(E_ALL & ~E_NOTICE);// Report all PHP errorserror_reporting(E_ALL);// Report all PHP errorserror_reporting(-1);// Same as error_reporting(E_ALL);ini_set('error_reporting', E_ALL);?>
Notes
Warning
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).
Tip
Passing in the value -1
will show every possible error,
even when new levels and constants are added in future PHP versions. The
E_ALL
constant also behaves this way as of PHP 5.4.
