mac php 7.2安装及 phalcon安装

一、使用homebrew安装 PHP 7.2

brew install php@7.2

修改环境 .zshrc 或.bashrc 的配置

export PATH="/usr/local/etc/php/7.2:$PATH"

重启命令行 这样默认就使用7.2

二、使用homebrew安装 phalcon

$ brew tap tigerstrikemedia/homebrew-phalconphp

$ brew install php72-phalcon

安装完毕以后，把phalcon加到php.ini里面，找到/usr/local/etc/php/7.2 的php.ini ，可以用添加这段（最好确认一下/usr/local/Cellar/php72-phalcon/ 中的地址）：

extension=/usr/local/Cellar/php72-phalcon/3.4.0/phalcon.so

修改好以后可以重启一下php

$ brew services restart php

查看是否安装

$ php -i | grep "phalcon."

如果可以看到如下信息：

phalcon => enabled

phalcon.db.escape_identifiers => On => On

phalcon.db.force_casting => Off => Off

phalcon.orm.cast_on_hydrate => Off => Off

phalcon.orm.column_renaming => On => On
