Youtube WatchLater to Playlist Script
<?php
/**
* Youtube Watch Later List To Playlist Script
*
* This script fetches your watch later list and outputs it as an M3U playlist
*
* Requirements:
* PHP enabled webserver
* Google PHP API (https://github.com/google/google-api-php-client)
* A YouTube API key (Oauth2, can be registered at https://console.developers.google.com/)
* Some kittens to sacrifice
*
* Initialization
* First ensure your webserver can write a file called "key.php" to the directory
* you put this file in. E.g. "touch key.php ; chmod ugo+w key.php"
* Next open the appropriate URL in your browser. You will be asked to pair
* this script with your YouTube-Account. If you configured everything correctly
* it will output the playlist and save your access codes in the key.php mentioned
* above. Successive requests do not require additional authentication. You may now
* put the URL in your YT-enabled media player like VLC.
*
* Based on examples by DomSammut (https://www.domsammut.com/code/php-server-side-youtube-v3-oauth-api-video-upload-guide)
