How do I check if a video exists on YouTube, using PHP?

Answer 1

Here is the solution that I use to check if YouTube video exists using video id. This is C# code, but basically you can check if the thumbnail of the video exists, you will either get 200 or 404 which is very convenient.

    private async Task VideoExists(string id)
    {
        var httpClient = new HttpClient();
        var video = await httpClient.GetAsync($"https://img.youtube.com/vi/{id}/0.jpg");
        return video.IsSuccessStatusCode;
    }
