_bw_improve_url() – Improves YouTube URL

Description

Improves YouTube URL

Notes: If the URL is like one of these below http://youtu.be/VIDEO_ID http://www.youtube.com/v/VIDEO_ID http://www.youtube.com/watch?v=HBVPKRW7QBU We replace it with the embed method http://www.youtube.com/embed/VIDEO_ID AND we also Enable privacy-enhanced mode using www.youtube-nocookie.com Unfortunately this method doesn't like &rel=0 when it becomes the first parameter so we need to convert the first & to a ? We also have to convert '&'s back to simple ampersands. Finally, we set the protocol depending on is_ssl() using set_url_scheme();

Usage

$string = _bw_improve_url( $url );

Parameters

$url

( string ) required – the requested URL

Returns

string the improved URL
