set_error_handler Function synopsis

$callback
Type?callable
If null is passed, the handler is reset to its default state.
Otherwise, the handler is a callback with the following signature:
$error_levels
OptionalTypeintDefault valueE_ALL

$callback function just like the error_reportingini setting
controls which errors are shown. Without this mask set the
$callback will be called for every error
regardless to the setting of the error_reportingsetting.
