The Plesk PHP Panda (P3) is a suite of multiple PHP versions to an  alternate location using redhats SCL structure,  Allowing the default  system version of PHP to remain in place. It is primarily
designed for Plesk hosting environments, but can be used on any RPM based system, including Redhat Enterprise Linux, Cloudlinux, and Centos.
Current Versions:
* PHP 5.6.0
* PHP 5.5.16
* PHP 5.4.32
* PHP 5.3.29 (Nucleus repo)
* PHP 5.2.17
The  Plesk PHP Panda is designed to enable you to have per domain PHP  options using FCGI mode in plesk.  While I  wrote this initially for plesk, its entirely possible that this could  be installed on other systems, like cpanel or directadmin.
In plesk 11.5, under your Domain -> Hosting Settings you will see 2 new options for FCGI php:
- Atomic 5.2
- Atomic 5.3
- Atomic  5.4
- Atomic  5.5
- Atomic 5.6
PHP 5.2 is now available.
Installation:
1) Set up the atomic yum repository
wget -q -O -

2) Install the Panda
yum install plesk-php-panda
3) (Nucleus subscribers)
yum install plesk-php53-panda
