Create support and resistance algorithm for crypto trading in php

The title says it all, I need a function to pass in an array of candle stick prices, and this function would calculate the support and resistance prices from the provided array. Basically what this link https://www.babypips.com/learn/forex/how-to-calculate-pivot-points is doing, but in PHP. Here’s another link to help you: https://stackoverflow.com/questions/8587047/support-resistance-algorithm-technical-analysis/49274744

I just need the implementation in PHP.
