YouTube has so many types of URLs to embed the video on your site. Sometimes it’s difficult to find a single regular expression to parse all type of YouTube URL and retrieve the video ID from it.
To retrieve the video ID from the YouTube URL, use this function,
|
1 2 3 4 5 6 |
function getVideoID($url) { $pattern = '#^(?:https?://)?(?:www\.)?(?:youtu\.be/|youtube\.com(?:/embed/|/v/|/watch\?v=|/watch\?.+&v=))([\w-]{11})(?:.+)?$#x'; preg_match($pattern, $url, $matches); return (isset($matches[1])) ? $matches[1] : false; } |
Regular Expression explanation is as follows,
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 |
$pattern = '#^(?:https?://)?'; # Either http or https. $pattern .= '(?:www\.)?'; # Optional, www subdomain. $pattern .= '(?:'; # Group host alternatives: $pattern .= 'youtu\.be/'; # Either youtu.be, $pattern .= '|youtube\.com'; # or youtube.com $pattern .= '(?:'; # Group path alternatives: $pattern .= '/embed/'; # Either /embed/, $pattern .= '|/v/'; # or /v/, $pattern .= '|/watch\?v='; # or /watch?v=, $pattern .= '|/watch\?.+&v='; # or /watch?other_param&v= $pattern .= ')'; # End path alternatives. $pattern .= ')'; # End host alternatives. $pattern .= '([\w-]{11})'; # Youtube video ids with standard length of 11 chars. $pattern .= '(?:.+)?$#x'; # Optional other ending URL parameters. |
