getting youtube video id the PHP

Question

I am currently writing a webapp in which some pages are heavily reliant on being able to pull the correct youtube video in - and play it. The youtube URLS are supplied by the users and for this reason will generally come in with variants one of them may look like this:

http://www.youtube.com/watch?v=y40ND8kXDlg

while the other may look like this:

http://www.youtube.com/watch/v/y40ND8kXDlg

Currently I am able to pull the ID from the latter using the code below:

function get_youtube_video_id($video_id)
{

    // Did we get a URL?
    if ( FALSE !== filter_var( $video_id, FILTER_VALIDATE_URL ) )
    {

        // http://www.youtube.com/v/abcxyz123
        if ( FALSE !== strpos( $video_id, '/v/' ) )
        {
            list( , $video_id ) = explode( '/v/', $video_id );
        }

        // http://www.youtube.com/watch?v=abcxyz123
        else
        {
            $video_query = parse_url( $video_id, PHP_URL_QUERY );
            parse_str( $video_query, $video_params );
            $video_id = $video_params['v'];
        }

    }

    return $video_id;

}

How can I deal with URLS that use the ?v version rather than the /v/ version?

Solution 1

Like this:

$link = "http://www.youtube.com/watch?v=oHg5SJYRHA0";
$video_id = explode("?v=", $link);
$video_id = $video_id[1];

Here is universal solution:

$link = "http://www.youtube.com/watch?v=oHg5SJYRHA0&lololo";
$video_id = explode("?v=", $link); // For videos like http://www.youtube.com/watch?v=...
if (empty($video_id[1]))
    $video_id = explode("/v/", $link); // For videos like http://www.youtube.com/watch/v/..

$video_id = explode("&", $video_id[1]); // Deleting any other params
$video_id = $video_id[0];

Or just use this regex:

(\?v=|/v/)([-a-zA-Z0-9]+)

Solution 2

<?php
// Here is a sample of the URLs this regex matches: (there can be more content after the given URL that will be ignored)

// http://youtu.be/dQw4w9WgXcQ
// http://www.youtube.com/embed/dQw4w9WgXcQ
// http://www.youtube.com/watch?v=dQw4w9WgXcQ
// http://www.youtube.com/?v=dQw4w9WgXcQ
// http://www.youtube.com/v/dQw4w9WgXcQ
// http://www.youtube.com/e/dQw4w9WgXcQ
// http://www.youtube.com/user/username#p/u/11/dQw4w9WgXcQ
// http://www.youtube.com/sandalsResorts#p/c/54B8C800269D7C1B/0/dQw4w9WgXcQ
// http://www.youtube.com/watch?feature=player_embedded&v=dQw4w9WgXcQ
// http://www.youtube.com/?feature=player_embedded&v=dQw4w9WgXcQ

// It also works on the youtube-nocookie.com URL with the same above options.
// It will also pull the ID from the URL in an embed code (both iframe and object tags)

preg_match('%(?:youtube(?:-nocookie)?\.com/(?:[^/]+/.+/|(?:v|e(?:mbed)?)/|.*[?&]v=)|youtu\.be/)([^"&?/ ]{11})%i', $url, $match);
$youtube_id = $match[1];
?>

Solution 3

<?php
$your_url='https://www.youtube.com/embed/G_5-SqD2gtA';
function get_youtube_id_from_url($url)
{
    if (stristr($url,'youtu.be/'))
        {preg_match('/(https:|http:|)(\/\/www\.|\/\/|)(.*?)\/(.{11})/i', $url, $final_ID); return $final_ID[4]; }
    else 
        {@preg_match('/(https:|http:|):(\/\/www\.|\/\/|)(.*?)\/(embed\/|watch.*?v=|)([a-z_A-Z0-9\-]{11})/i', $url, $IDD); return $IDD[5]; }
}

echo get_youtube_id_from_url($your_url)
?>

Solution 4

Try:

function youtubeID($url){
     $res = explode("v",$url);
     if(isset($res[1])) {
        $res1 = explode('&',$res[1]);
        if(isset($res1[1])){
            $res[1] = $res1[0];
        }
        $res1 = explode('#',$res[1]);
        if(isset($res1[1])){
            $res[1] = $res1[0];
        }
     }
     return substr($res[1],1,12);
     return false;
 }
$url = "http://www.youtube.com/watch/v/y40ND8kXDlg";
echo youtubeID($url1);

Should work for both

Solution 5

Okay, this is a much better answer than my previous:

  $link = 'http://www.youtube.com/watch?v=oHg5SJYRHA0&player=normal';

  strtok($link, '?');

  parse_str(strtok(''));

  echo $v;

It's might be good to have this in a function to keep the new variables out of the global scope (unless you want them there, obviously).

If you copy/paste urls from youtube website, there are often other parameters, such as `youtube.com/watch?v=oHg5SJYRHA0&player=normal&... There can be a dozen of these.

This will not always work. If you copy/paste urls from youtube website, there are often other parameters, such as http://www.youtube.com/watch?v=oHg5SJYRHA0&player=normal&... There can be a dozen of these. Your code will produce the ID of oHg5SJYRHA0&player=normal&...` - which is clearly wrong

[Aleks G]

This might work with the / URL, but will not always work with the other type. If you copy/paste urls from youtube website, there are often other parameters, such as youtube.com/watch?v=oHg5SJYRHA0&player=normal&... There can be a dozen of these. Judge for yourself what will happen if you search for the last =

[Daniil Ryzhkov]

Fixed that. Look at the new solution.

[Maik]

oh thats right. but if you search for the first appearance of "v=" or "v/" you get the start of the id. the end of the id is the end of the string or the next "&".

Or look at my code here: github.com/lingtalfi/video-ids-and-thumbnails/blob/master/… It handles various youtube urls, and vimeo and dailymotion too.
