Regular expressions help required

gokulnk (63)in #steemgig • 7 years ago

To extract "w6OyOZXoq14" from the string https://www.youtube.com/watch?v=w6OyOZXoq14 we can use the below preg_match in php.

preg_match('/^https?:\/\/(www\.)?((?!.*list=)youtube\.com\/watch\?.*v=|youtu\.be\/)(?<id>[0-9A-Za-z_-]*)/', $input, $matches);
return isset($matches['id']) ? $matches['id'] : FALSE;

Similarly I need to extract "dollarvigilante/4iknjlwx" from "https://dtube.video/#!/v/dollarvigilante/4iknjlwx"

Can somebody lend a quick helping hand? I generally head to stackoverlfow for these kinds of queries. Trying to see if it can work on steemit itself.
