First of all, I have to say that I love mamp and it has become an indispensable tool in my environment.
But one thing I miss a lot is the integration of the PHP Phalcon extensions. (https://phalcon.io)
It is one of my most used frameworks and is hard to integrate. When compiling on my Mac I always get an error message and the compiled versions I used to use are no longer accepted.
It would be great if you could provide a PHP version including phalcon.
