2016/07/05
 
The version of PHP in CentOS 7 repository is 5.4 but Install 7.1 with RPM package if you need.

It's OK to install it even if 5.4 is already installed because 7.1 is located on another PATH.

yum --enablerepo=remi-safe -y install php71 php71-php-pear php71-php-mbstring
[2] PHP 7.1 is installed under the /opt directory and the link "/bin/php71" is created.
