I'm going to answer my own question:

It's possible to make a PayPal payment using PHP only, it's called Implicit approval payments

Implicit approval payments are payments where the sender and the API caller are using the same account. Because PayPal draws the funds for the payment from your own account, there is no approval necessary, and as such there is no visible flow for implicit approval payments.

I tried using the Pay API and the payment is made within the PHP script, no need for a web flow or any other manual approvement.

The Pay API requires an extra field, called senderEmail, set this field to the PayPal email user account
