Answer 1

Here is a function to extract the video id from a youtube link:

function getVideoID(url){
  var id = '';
  url = url.replace(/(>|<)/gi,'').split(/(vi\/|v=|\/v\/|youtu\.be\/|\/embed\/)/);
  if(url[2] !== undefined) {
    id = url[2].split(/[^0-9a-z_\-]/i);
    id = id[0];
  }  else {
    id = url;
  }
  return id;
}

Returns the video ID not only in the scenario you suggested, but also in many others:

I'm looking at the answers above .... I'm in shock, guys, or I don't understand something ...
One riveted regular expression, the other answered PHP in general, the third one wants to cut off by the number of characters. Poor line...

var inputString = "www.youtube.com/watch?v=2XBwL_KEpg";
alert(inputString.split("v=")[1]);  //2XBwL_KEpg

$fulluri = preg_replace("/\?.*/i",'', $_SERVER['REQUEST_URI']);
$ww =strlen($fulluri) ;
 if ($ww >14  xor $ww ==54 xor $ww ==38 xor $ww ==33 )   { header("HTTP/1.1 301 Moved Permanently");header( 'Location: /v', true, 303 ); exit(); };
$fulluri = strip_tags($fulluri); 
$fulluri = trim($fulluri);
$ww = $fulluri;
$fulluri =  substr($fulluri, 3, 11);
$ww =  substr($ww, 14, 54);
