Comment (by loru88):

 @shulard as I know ''parse_url'' doesn't validate the url

 The idea of a dedicated function is ok, but I upload a patch to validate
 the url against a simple regex.
 It takes into consideration just http and https, a valid hostname or ip
 address, an optional port and an optional path.

 a filter is applied to the regex in case someone needs different
 validation pattern.

 I taked inspiration from Symfony UrlValidator but I simplified the regex:
 [https://github.com/symfony/validator/blob/master/Constraints/UrlValidator.php]

 Could be useful to add a unit test on this function.
