Tons of people selected YouTube video making as a full-time job, as they create and upload videos and getting revenue from YouTube Adsense( Google Adsense). But, YouTube lacks one important feature, direct download of videos to users’ computers or mobiles. That’s why we created this tutorial,   and we will show how to download YouTube videos using PHP. This YouTube downloader PHP script 2021 helps you to download 90% of Youtube videos from Youtube.

Main Features of this YouTube Videos downloader

  • Easy to Install
  • Easy to Customize (This is a very basic PHP script, and easily customizable)
  • Fast Loading without cache mechanism
  • No Database Required.
  • No installation required, just copy-paste the script to your web server that runs PHP

First things first, we have the below scripts to work YouTube downloader.

  1. index.php
  2. class.youtube.php
  3. downloader.php

First, we will examine the class.youtube.php as this is the core file that executes important features for downloading a video from YouTube.

  • getYouTubeCode – Get the YouTube code from a video URL
  • processVideo – Process the video url and return details of the video
<?php
/**

 * @class YouTubeDownloader

 */

Class YouTubeDownloader {

    /**
     * Get the YouTube code from a video URL
     * @param $url
     * @return mixed
     */
    public function getYouTubeCode($url) {
        parse_str( parse_url( $url, PHP_URL_QUERY ), $vars );
        return $vars['v'];
    }

    /**
     * Process the video url and return details of the video
     * @param $vid
     * @return array|void
     */

    public function processVideo($vid) {
        parse_str(file_get_contents("https://youtube.com/get_video_info?video_id=".$vid),$info);


        $playabilityJson = json_decode($info['player_response']);
        $formats = $playabilityJson->streamingData->formats;
        $adaptiveFormats = $playabilityJson->streamingData->adaptiveFormats;

        //Checking playable or not
        $IsPlayable = $playabilityJson->playabilityStatus->status;

        //writing to log file
        if(strtolower($IsPlayable) != 'ok') {
            $log = date("c")." ".$info['player_response']."\n";
            file_put_contents('./video.log', $log, FILE_APPEND);
        }

        $result = array();

        if(!empty($info) && $info['status'] == 'ok' && strtolower($IsPlayable) == 'ok') {
            $i=0;
            foreach($adaptiveFormats as $stream) {

                $streamUrl = $stream->url;
                $type = explode(";", $stream->mimeType);

                $qualityLabel='';
                if(!empty($stream->qualityLabel)) {
                    $qualityLabel = $stream->qualityLabel;
                }

                $videoOptions[$i]['link'] = $streamUrl;
                $videoOptions[$i]['type'] = $type[0];
                $videoOptions[$i]['quality'] = $qualityLabel;
                $i++;
            }
            $j=0;
            foreach($formats as $stream) {

                $streamUrl = $stream->url;
                $type = explode(";", $stream->mimeType);

                $qualityLabel='';
                if(!empty($stream->qualityLabel)) {
                    $qualityLabel = $stream->qualityLabel;
                }

                $videoOptionsOrg[$j]['link'] = $streamUrl;
                $videoOptionsOrg[$j]['type'] = $type[0];
                $videoOptionsOrg[$j]['quality'] = $qualityLabel;
                $j++;
            }
            $result['videos'] = array(
                'info'=>$info,
                'adapativeFormats'=>$videoOptions,
                'formats'=>$videoOptionsOrg
            );
            
            
            return $result;
        }
        else {
            return;
        }
    }

}

In processVideo() function, first we parse the outputs from the YouTube video info page. It is important to note that, chunks of data returning from this line of code, but we will not use all of this. Next, we check the status to see if it’s ok, then move to the next steps of parsing the different streams by using this code $playabilityJson->streamingData->adaptiveFormats.

It returns different versions of  YouTube video such as mp4, mp3, and most importantly various qualities(720p,360p). Finally, we push all these to an array and set the value in return.

Download the YouTube video by using a simple form in PHP

We use the below form to take users input ie. YouTube video url. This comes in the index.php.

<form method="post" action="" class="formSmall">
	<div class="row">
		<div class="col-lg-12">
			<h7 class="text-align"> Download YouTube Video</h7>
		</div>
		<div class="col-lg-12">
			<div class="input-group">
				<input type="text" class="form-control" name="video_link" placeholder="Paste link.. e.g. https://www.youtube.com/watch?v=OK_JCtrrv-c">
				<span class="input-group-btn">
				<button type="submit" name="submit" id="submit" class="btn btn-primary">Go!</button>
			  </span>
			</div><!-- /input-group -->
		</div>
	</div><!-- .row -->
</form>

Next, we have to write our PHP code that inputs the video ID and return the different video URLs for download.

<?php
require_once "class.youtube.php";
$yt  = new YouTubeDownloader();
$downloadLinks ='';
$error='';
if($_SERVER['REQUEST_METHOD'] == 'POST') {
    $videoLink = $_POST['video_link'];
    if(!empty($videoLink)) {
        $vid = $yt->getYouTubeCode($videoLink);
        if($vid) {
            $result = $yt->processVideo($vid);
            
            if($result) {
                //print_r($result);
                $info = $result['videos']['info'];
                $formats = $result['videos']['formats'];
                $adapativeFormats = $result['videos']['adapativeFormats'];

                

                $videoInfo = json_decode($info['player_response']);

                $title = $videoInfo->videoDetails->title;
                $thumbnail = $videoInfo->videoDetails->thumbnail->thumbnails{0}->url;
            }
            else {
                $error = "Something went wrong";
            }

        }
    }
    else {
        $error = "Please enter a YouTube video URL";
    }
}
?>

Above script, we include the class fileclass.youtube.php, which is the core of this application. Finally, we confirm the POST method and fetch the results from the class methods.

The below code will show you how to display the YouTube download links in a tabular format, with quality and type.

<?php if($formats):?>
        <div class="row formSmall">
            <div class="col-lg-3">
                <img src="<?php print $thumbnail?>">
            </div>
            <div class="col-lg-9">
                <?php print $title?>
            </div>
        </div>

        <div class="card formSmall">
            <div class="card-header">
                <strong>With Video & Sound</strong>
            </div>
            <div class="card-body">
                <table class="table ">
                    <tr>
                        <td>Type</td>
                        <td>Quality</td>
                        <td>Download</td>
                    </tr>
                    <?php foreach ($formats as $video) :?>
                        <tr>
                            <td><?php print $video['type']?></td>
                            <td><?php print $video['quality']?></td>
                            <td><a href="downloader.php?link=<?php print urlencode($video['link'])?>&title=<?php print urlencode($title)?>&type=<?php print urlencode($video['type'])?>">Download</a> </td>
                        </tr>
                    <?php endforeach;?>
                </table>
            </div>
        </div>

        <div class="card formSmall">
            <div class="card-header">

                        <td>Download</td>
                    </tr>
                    <?php foreach ($adapativeFormats as $video) :?>
                        <tr>
                            <td><?php print $video['type']?></td>
                            <td><?php print $video['quality']?></td>
                            <td><a href="downloader.php?link=<?php print urlencode($video['link'])?>&title=<?php print urlencode($title)?>&type=<?php print urlencode($video['type'])?>">Download</a> </td>
                        </tr>
                    <?php endforeach;?>
                </table>
            </div>
        </div>
        <?php endif;?>

How to download the video using the link?

You may have noticed there is a page called downloader.php in the above script. This script is responsible for the force download of the file to your computer or mobile. This is the standard force download process in PHP.

<?php
$downloadURL = urldecode($_GET['link']);
//print  $downloadURL;exit;
$type = urldecode($_GET['type']);
$title = urldecode($_GET['title']);

//Finding file extension from the mime type
$typeArr = explode("/",$type);
$extension = $typeArr[1];

$fileName = $title.'.'.$extension;


if (!empty($downloadURL)) {
    header("Cache-Control: public");
    header("Content-Description: File Transfer");
    header("Content-Disposition: attachment;filename=\"$fileName\"");
    header("Content-Transfer-Encoding: binary");

    readfile($downloadURL);

}

I hope everyone enjoyed this article, don’t forget to share this article with your peers.

UPDATE(20 Aug 2020)

The adaptive formats in YouTube provide videos with video only and audios with audio-only options. But we have updated the script with two other formats that are available with both audio and video.  The only solution to work with different quality is to merge audio and video from adaptive formats.  We are not going very deep with ffmpg, but you may install and play with this cross-platform solution to record, convert and stream audio and video.

A sample command would be

ffmpeg -i videoplayback.mp4 -i videoplayback.m4a -c:v copy -c:a copy output.mp4

      In this simple script, we are using publicly available YouTube API (https://youtube.com/get_video_info?video_id=ID and it’s restricted to show licensed content’s download links. You are not supposed download a licensed material unless you pay for it.

      Not sure how those other apis works, I should invest some time to dig in to that..

      This is not just you, it happens on all my Apache2 servers. Luckily I’m using Nginx, which doesn’t show any errors by default. The script is working fine on both, if you look past the loads of errors on Apache.

    Why is it that various other download sites and youtube-dl have no trouble finding the googlevideo.com URLs for videos with music, but this script doesn’t find anything for almost every video with music? Normal videos seem to work fine, official audio or music videos give an error. I get that there are restricted videos, but what are the other parties mentioned doing different? Thanks for the script anyway, this is just out of curiosity!

      Check if you have supplied a valid youtube url. Please note that this script is just a demo, so you need tweak the validations and other parts etc?

    script works great except that the script gives an error on random videos.
    I have a series of videos in a you tube channel, they have all similar information and format.
    The first video in the chain won’t download, the rest will.
    the error log is a jumble and I can’t really make out what the error is as to why it won’t come up with the file formats when we go to download. I tried this with the default script in the zip file as well, withouth any of my html modifications.

    any suggestions?

    I like the script and it works just as simple as it is.

    Is there a way to get a shorter download link?
    So the link can be shared after creating the download link.

    Thank You!
