This class mimics the algorithm used by YouTube to generate unique video IDs.
- We define a class called
YoutubeVideoIdGenerator
that represents our YouTube video ID generator. - We define three constants:
VIDEO_ID_LENGTH
with a value of 11, which represents the length of a YouTube video ID,VIDEO_ID_CHARACTERS
with a string that contains all the characters that can be used in a YouTube video ID, andDEFAULT_ALGORITHM
with a value ofsha256
, which represents the default algorithm to use for ID generation. - We define two private properties:
$algorithm
, which represents the algorithm to use for ID generation, and$secret_key
, which represents the secret key to use for ID generation. We also define a constructor that allows us to set the$secret_key
and$algorithm
properties. - We define a public method called
generateId
that generates a YouTube video ID. This method calls two private methods:generateRandomString
andconvertHashToId
.generateRandomString
generates a random string of characters with a length of 11 using the characters inVIDEO_ID_CHARACTERS
, whileconvertHashToId
converts a hash generated by the algorithm and the random string to a YouTube video ID. - We define two private methods:
generateRandomString
andconvertHashToId
.generateRandomString
generates a random string of characters with a length of 11 using the characters inVIDEO_ID_CHARACTERS
, whileconvertHashToId
converts a hash generated by the algorithm and the random string to a YouTube video ID. - We define a public method called
getVideoLink
that returns the YouTube video link for a given video ID.
To use this class, you can create an instance of it with a secret key:
$generator = new YoutubeVideoIdGenerator('your_secret_key');
# You can then generate a YouTube video ID:
$video_id = $generator->generateId();
# Finally, you can get the YouTube video link for the generated ID:
$video_link = $generator->getVideoLink($video_id);
echo $video_link;
This will output a link like https://www.youtube.com/watch?v=LhiFw_2EasE, which is a valid YouTube video link.
