Hello,

May I ask if you’re using Apache or Nginx and if you’re running CentOS or Ubuntu and which version as well?

You can follow these steps to install PHP 5.6 on CentOS 7

First install the EPEL repository:

rpm -Uvh http://vault.centos.org/7.0.1406/extras/x86_64/Packages/epel-release-7-5.noarch.rpm

Instal the remi repository

rpm -Uvh http://rpms.famillecollet.com/enterprise/remi-release-7.rpm

Enable remi

yum --enablerepo=remi,remi-php56 install php php-common

Install PHP 5.6

yum --enablerepo=remi,remi-php56 install php-cli php-pear php-pdo php-mysql php-mysqlnd php-pgsql php-sqlite php-gd php-mbstring php-mcrypt php-xml php-simplexml php-curl php-zip

systemctl restart httpd.service

If you have any server panel you should see PHP 5.6 as available and if not you can use .htaccess file to make 5.6 default for your site.

AddHandler application/x-httpd-php56 .php 

Let me know how it goes.
