Super simple way to switch between multiple versions of Linux PHP

First: find command to find where php is first

#find / -name php

The first step: ln command (a lot of resources under Baidu) is mainly used to create Soft connection

Now I mainly want to change the 5.4 version to the 5.5 version:

#ln -s /usr/local/php-5.5/bin/php(你想要换成的php版本的路径) /usr/sbin/php（最后一个php可以换成你自己喜欢的名字，最好php吧）

The second step: the export command adds the soft connection to the PATH path

#export PATH="$PATH:/usr/sbin/php"（将上面你准备好的连接加进去就可以了，中间：冒号别漏了，用来做分割的）

Finally: see Next effect

#php -v
