error_reporting — Sets which PHP errors are reported

Опис

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.

Параметри

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.

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.
