--EXPECTF--
Deprecated: ini_set(): Using a value different than 0 for intl.error_level is deprecated, as the intl.error_level INI setting is deprecated. Instead the intl.use_exceptions INI setting should be enabled to throw exceptions on errors or intl_get_error_code()/intl_get_error_message() should be used to manually deal with errors in %s on line %d
