Parse Youtube ID from Youtube URL

[defroster]

How could I from the varying URLs parse only the YouTube video ID?

How can I from the URLs above only extract the id into a variable $url

Actually just stumbled upon one which works well.

 

/* 
 * Retrieve the video ID from a YouTube video URL
 * @param $ytURL The full YouTube URL from which the ID will be extracted
 * @return $ytvID The YouTube video ID string
 */
function getYTid($ytURL) {

	$ytvIDlen = 11;	// This is the length of YouTube's video IDs

	// The ID string starts after "v=", which is usually right after 
	// "youtube.com/watch?" in the URL
	$idStarts = strpos($ytURL, "?v=");

	// In case the "v=" is NOT right after the "?" (not likely, but I like to keep my 
	// bases covered), it will be after an "&":
	if($idStarts === FALSE)
		$idStarts = strpos($ytURL, "&v=");
	// If still FALSE, URL doesn't have a vid ID
	if($idStarts === FALSE)
		die("YouTube video ID not found. Please double-check your URL.");

	// Offset the start location to match the beginning of the ID string
	$idStarts +=3;

	// Get the ID string and return it
	$ytvID = substr($ytURL, $idStarts, $ytvIDlen);

	return $ytvID;

}
