php - validate URL by FILTER_VALIDATE_URL -



php - validate URL by FILTER_VALIDATE_URL -

i validating url filter_validate_url function.

$url_1 = "http://example.com"; $url_2 = "http://http://example.com"; if (filter_var($url_1, filter_validate_url)) { echo "url valid"; } else { echo "url invalid"; }

it's giving me valid url message in $url_1 , $url_2. shouldn't that. sec url not valid. what's right way solve issue? thanks.

as per docs on validation filters, filter_validate_url validate url rfc 2396 standards.

there's been give-and-take on examples still pass filter_validate_url filter.

this means can utilize filter some validation, can't depend on solely if need 100% valid url conditions still satisfy rfc, plus valid url still homecoming 404.

your best approach test valid url test url after validating as per answer

php validation
