如何在macOS Mojave上安装PHP交易者扩展？

Question

I've been struggling to install PHP trade extension on macOS Mojave, but so far I haven't been able to do this. I run this command in terminal:

$ sudo pecl install trader

But, I got this error:

fatal error: 'php.h' file not found

include "php.h"

Then, I tried:

$ brew link --overwrite php 

But I got another error:

Error: No such keg: /usr/local/Cellar/php

Does anyone knows about this errors or have any tutorial to help me to install it?
