A Simple Reddit downloader with PHP

#php #laravel #web #curl

So, first step is to get source code of page from where we gonna extract video url, here is code how it would be done,

$uri = 'https://www.reddit.com/r/interestingasfuck/comments/130fgu1/interviewing_with_the_kkk_footage_might_disturbing/';

$ch = curl_init();
  curl_setopt($ch, CURLOPT_URL, $uri);
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
  curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.3');
  $html = curl_exec($ch); // here in html page's source stored
  curl_close($ch);

In the next we gonna find that video url by regex equation,

$video_regex = '/(https:\/\/v\.redd\.it\/[a-z0-9]+\/HLSPlaylist\.m3u8).*?/';
  preg_match($video_regex, $html, $videoUrl);

and then from this equation we will get video id and print output

$url = $videoUrl[0];
    $regex1 = '/https:\/\/v\.redd\.it\/(\w+)\/HLSPlaylist\.m3u8/';
    preg_match($regex1, $url, $video);
    $video_id = $video[1];
     echo '<video controls src="https://v.redd.it/' . $video_id . '/DASH_720.mp4"  type="video/mp4" width="320"></video>';

here is final output with GUI https://redditdownloader.org/
