Develop a simple code to get some youtube information (click for detailed info)

Hello I want a simple HTML page (that maybe will have to comunicate with any kind of API on php) to run some algorith the programing is basic, the HTML page will have a box to an user add a YouTube channel URL and click in "send" button. I'll give you an algorithm to calculate a grade based on: -> How many subscribes there are on this youtube channel -> How videos there are on lasts 10 days -> How many views there are on each videos from lasts 10 days -> How many likes there are on each videos on lats 10 days The algorithm I'll make, so you only have to implement this and make the code to check the YouTube channel URL the user will put and get those informations from channel Why do you need that? A lot of players are asking me for sponsorship for anything based on their youtube channel, so I'll make a grade for each channel based on how popular it is and say to people we only can make this sponsorship if they have at least grade X. That is the idea
