OSX 改变PHP安装路径环境变量
当使用XAMPP来学习Laravel的时候，用composer安装laravel总是报错，说mcrypt is required ，但是当我在终端里打印 which php 显示的是usr/bin/php 没有用XAMPP安装的PHP，所以要改成使用XAMPP中的PHP版本，做法如下：To those that uses XAMPP 1.7.3 and Mac
[*]Go to Terminal
[*]Enterwhichphp
[*]If it says /usr/bin/php, then proceed to 3.
[*]Entersudonano ~/.bash_profile(orsudovim ~/.bash_profileif you know how to use it)
[*]Then paste thisexportPATH="/Applications/XAMPP/xamppfiles/bin:$PATH"
[*]Ctrl - O then enter to save, then ctrl - X to exit.
[*]Type cd ~
[*]type . .bash_profile
[*]restart terminal.
[*]Enterwhichphp
Good luck
