Mac环境搭建PHP开发环境（一）------------------mac升级自带的PHP版本7及注意事项

题外话：在OSX 系统最好使用mac下的软件包管理brew安装:

 1.安装 brew,又称homebrew

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

　　brew常用命令:　　

brew update                        #更新brew可安装包
brew search php70                  #搜索php7.0
brew tap josegonzalez/php          #安装josegonzalez 的php安装包
brew tap                           #查看安装的扩展列表
brew install php70                 #安装php7.0
brew remove  php70                 #卸载php7.0
brew upgrade php70                 #升级php7.0
brew options php70                 #查看php7.0安装选项
brew info    php70                 #查看php7.0相关信息
brew home    php70                 #访问php7.0官方网站
brew services list                 #查看系统通过 brew 安装的服务
brew services cleanup              #清除已卸载无用的启动配置文件
brew services restart php70        #重启php-fpm

2.install PHP

　　首先添加brew的PHP扩展库：

brew update
brew tap homebrew/dupes
brew tap homebrew/php
brew tap josegonzalez/homebrew-php

可以使用 brew options php70 命令来查看安装php7.0的选项，显示如下

--with-cgi
    Enable building of the CGI executable (implies --without-fpm)
　　
--with-debug
    Compile with debugging symbols
--with-enchant
    Build with enchant support
--with-gmp
    Build with gmp support
--with-homebrew-curl
    Include Curl support via Homebrew
--with-homebrew-libressl
    Include LibreSSL instead of OpenSSL via Homebrew
--with-homebrew-libxml2
    Include Libxml2 support via Homebrew
--with-homebrew-libxslt
    Include LibXSLT support via Homebrew
--with-httpd22
    Enable building of shared Apache 2.2 Handler module
--with-httpd24
    Enable building of shared Apache 2.4 Handler module
--with-imap
    Include IMAP extension
--with-libmysql
    Include (old-style) libmysql support instead of mysqlnd
--with-mssql
    Include MSSQL-DB support
--with-pdo-oci
    Include Oracle databases (requries ORACLE_HOME be set)
--with-pear
    Build with PEAR
--with-phpdbg
    Enable building of the phpdbg SAPI executable
--with-postgresql
    Build with postgresql support
--with-thread-safety
    Build with thread safety
--with-webp
    Build with webp support
--without-bz2
    Build without bz2 support
--without-fpm
    Disable building of the fpm SAPI executable
--without-ldap
    Build without LDAP support
--without-legacy-mysql
    Do not include the deprecated mysql_ functions
--without-mysql
    Remove MySQL/MariaDB support
--without-pcntl
    Build without Process Control support
--without-unixodbc
    Build without unixODBC support
--HEAD
    Install HEAD version

这里我用下面的选项安装：

brew install php70 --with-apache --with-gmp --with-imap --with-tidy --with-debug

　　注意如果你希望以mac下的apache作为web server，编译时要加 --with-apache；如果你的web server 是 nginx这类，就需要加上 --with-fpm。重要的事情应定要看。
安装成功，命令行中输入php -v，还是会显示mac自带的旧版本。因此，我们还需要配置一下路径。


sudo vim ~/.bashrc

在文件末尾添加

最后命令行执行

　　

source ~/.bashrc

全部搞定。命令行输入 php -v 显示　　

恭喜你成功了。
