MAC利用brew命令安装PHP7环境的方法

最近几年一直在LNMP环境下进行开发，其中的PHP还是5.5版本，有点老旧，去年12月PHP7已经正式发布，新增了一些语法特性，最大的亮点是性能的提升，所以一直想升级到PHP7,由于时间关系一直拖到现在。到写本文为止PHP最新版本为：7.0.9的stable，所以稳定性上基本不用担心。

之前写的 MAC下安装LNMP环境 是用brew安装的，这次升级PHP7继续使用brew, 安装/升级软件很方便。

升级brew

brew update
配置

brew tap homebrew/dupes
brew tap homebrew/versions 
brew tap homebrew/homebrew-php
安装PHP7

brew install php70
遇到的问题

安装提示：

➜  ~ brew install php70
==> Installing php70 from homebrew/php
Error: Cannot install homebrew/php/php70 because conflicting formulae are installed.

  php55: because different php versions install the same binaries.

Please `brew unlink php55` before continuing.

Unlinking removes a formula's symlinks from /usr/local. You can
link the formula again after the install finishes. You can --force this
install, but the build may fail or cause obscure side-effects in the
resulting software.
根据提示执行： brew unlink php55
继续安装: brew install php70

配置文件

安装好后生成的配置文件都在 /usr/local/etc/php/7.0 目录里，分别如下：

php.ini /usr/local/etc/php/7.0/php.ini
php-fpm.conf /usr/local/etc/php/7.0/php-fpm.conf
php, phpize, php-config ls /usr/local/opt/php70/bin
php-fpm /usr/local/opt/php70/sbin/php-fpm

加入开机启动

mkdir -p ~/Library/LaunchAgents
ln -sfv /usr/local/opt/php70/homebrew.mxcl.php70.plist ~/Library/LaunchAgents/
launchctl load -w ~/Library/LaunchAgents/homebrew.mxcl.php70.plist
命令行配置

vim ~/.zshrc
将
export PATH="$(brew --prefix php55)/bin:$PATH"
替换为
export PATH="$(brew --prefix homebrew/php/php70)/bin:$PATH"

alias php-fpm.start="launchctl load -w ~/Library/LaunchAgents/homebrew.mxcl.php55.plist"
alias php-fpm.stop="launchctl unload -w ~/Library/LaunchAgents/homebrew.mxcl.php5.plist"
alias php-fpm.restart='php-fpm.stop && php-fpm.start'
修改为

alias php-fpm.start="launchctl load -w ~/Library/LaunchAgents/homebrew.mxcl.php70.plist"
alias php-fpm.stop="launchctl unload -w ~/Library/LaunchAgents/homebrew.mxcl.php70.plist"
alias php-fpm.restart='php-fpm.stop && php-fpm.start'
重新加载配置文件

source ~/.zshrc
