Install the php7 environment using yum in Centos 6/7

The official PHP 7 version was released in early December 2015 and is welcomed by the largest version since 2004. The most significant change in PHP7 is the performance improvement, which is close to the PHP execution engine HHVM developed by Facebook. In the benchmark performance test of WordPress, the speed is 2 ~ faster than that of version 5.6 ~ 3 times, greatly reducing memory usage. PHP 7 also has some language changes, such as adding a return type declaration and adding some new reserved keywords. In terms of security, remove the PHP Security mode and add magic quotes. In addition, the new version supports 64-bit and the latest Zend Engine.
