In this article, I'll show you how to upgrade PHP 5.3 to PHP 5.6 on CentOS 6.7.

This article assumes that you have installed CentOS and that you have installed PHP 5.3

1. Verify the current version of PHP

Type the following to view the current PHP version:

php -v

The output should be as follows:

PHP 5.3.3 (cli) (built: Jul 9 2015 17:39:00) 
Copyright (c) 1997-2010 The PHP Group
Zend Engine v2.3.0, Copyright (c) 1998-2010 Zend Technologies

OK, now we can move on!

2. Install the Remi and Epel rpm repositories

If you have not done so, install the Remi and Epel repositories

wget https://dl.fedoraproject.org/pub/epel/epel-release-latest-6.noarch.rpm && rpm -Uvh epel-release-latest-6.noarch.rpm

wget http://rpms.famillecollet.com/enterprise/remi-release-6.rpm && rpm -Uvh remi-release-6*.rpm

To enable the Remi repository globally:

nano /etc/yum.repos.d/remi.repo

Make the following changes in the section below [Remi]:
