error_reporting

(PHP 4, PHP 5, PHP 7, PHP 8)

error_reporting — Sets which PHP errors are reported

Description ¶

error_reporting(?int $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.

Parameters ¶

error_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 error_level parameter is given.

// 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);
