As of PHP 5.2.1 FILTER_VALIDATE_URL implies FILTER_FLAG_SCHEME_REQUIRED | FILTER_FLAG_HOST_REQUIRED, which makes these constants useless at best, if not even misleading. Therefore we deprecate the explicit use of these constants for FILTER_VALIDATE_URL, to pave the way for their eventual removal. See also <https://bugs.php.net/75442> and <https://externals.io/message/100981>.

This has been added to the “Deprecations for PHP 7.3” RFC, so don't merge until accepted. |
|
Would you like to add a test for this deprecation? |
Sure. I'll catch up on this ASAP. |
We settle for testing filter_var() only instead of all relevant filter functions, and make sure that we do not only test the actual deprecation message, but also that FILTER_FLAG_SCHEME_REQUIRED and FILTER_FLAG_HOST_REQUIRED are implicitly used.
