New AFIP API in PHP

How to implement the new SOAP service of the API of AFIP in PHP ?

This question is born since I know that many people have the same thing and I hope we will reach a solution.

Until just over a week ago I had been using the api rest of AFIP which I was consulting by passing a cuit parameter via the url and receiving a Json of the data.

However, for some reason they decided to cancel it, leaving my whole system obsolete. And also the non-existent documentation that I found is in python

Now I must manage to make a refactor of my app updating the method with which I obtain the data and using the new version of the API in SOAP

REST API:

" link "

SOAP API:

" link "

Unfortunately my knowledge of WS SOAP is almost nil. That's why I'm asking in this way.

According to this manual (in my opinion unintelligible):

" link "

I must use the method getPersona()

Here is the example code provided by the official website:

!/usr/bin/php
