Youtube渠道网址到渠道ID（PHP）

Question

I am making a web app using the YT Api V3 and I need my users to input their YT channel URL. I want my PHP script to convert this URL to a channel Id (I built all my script with channel Id methods and I dont want to modify all the files).

My question is : In PHP, how can I convert a YouTube channel URL to a YouTube channel Id ?

Answer 1

A standard YouTube channel URL looks like this: https://www.youtube.com/channel/[channel-id]

You may use a function like this to parse the channel ID:

function parse_channel_id(string $url): ?string {
        $parsed = parse_url(rtrim($url, '/'));
        if (isset($parsed['path']) && preg_match('/^\/channel\/(([^\/])+?)$/', $parsed['path'], $matches)) {
                return $matches[1];
        }
        throw new Exception("{$url} is not a valid YouTube channel URL");
        return null;
}
