This package can get information and download a video from YouTube.

It can take the ID string or the URL of a video on YouTube and sends HTTP requests to YouTube API to retrieve information about that specific video, like the video title and audio and video format available for a video.

The package can also serve the video stream for download.

A php only youtube parser and downloader

Zanfi Youtube downloader is a blazing fast Youtube parser and Audio+Video or Audio only downloader.

It uses only 1 php class without third party software. It makes no use of the Youtube API (so no api key is needed).

Inspired from the (php) Athlon1600/youtube-downloader and, of course, from the youtube-dl and yt-dlp which are built with Python.

I was annoyed by the throttling that Youtube uses when downloading from an adaptive stream. With this class I measured download speeds even better than yt-dlp.

Just before putting this class online, I got this result:

\- Downloaded 5148614 bytes in 0.56019806861877 seconds

How to use the class:

include the class in your php code.

require('ZanfiYouTube.php');

initialize the class with a yotube video ID or a youtube video url

$ZanfiYouTube = new ZanfiYouTube('WaEKXGlfYj8');

or

$ZanfiYouTube = new ZanfiYouTube('https://www.youtube.com/watch?v=WaEKXGlfYj8');

The most important data is stored in:

$ZanfiYouTube->arr_Video_info;
$ZanfiYouTube->arr_Video_formats;
$ZanfiYouTube->arr_Video_adaptive_formats;
$ZanfiYouTube->arr_Video_thumbnails;

just print what you need to see:

$ZanfiYouTube->printFormatted($ZanfiYouTube->arr_Video_adaptive_formats);

print the array with the best video+audio data

$ZanfiYouTube->printFormatted($ZanfiYouTube->get_best_both());

print the array with the best audio data

$ZanfiYouTube->printFormatted($ZanfiYouTube->get_best_audio());

Starts download of video+audio

$ZanfiYouTube->download_best_both();

Starts download of audio only

$ZanfiYouTube->download_best_audio();

shows the elapsed time for download (use it only after a download...)

echo('Downloaded ' . $ZanfiYouTube->downloaded_bytes . ' bytes in ' . $ZanfiYouTube->elapsed_time . ' seconds');
