In this article, I’m going to show you how to upgrade PHP 5.3 to PHP 5.6 on CentOS 6.7.

This article assumes you have a stock installation of CentOS, and that you already have PHP 5.3 installed



1. Verify current version of PHP



Type in the following to see the current PHP version:



php -v



Should output something like:



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



Great, now we can move on!



2. Install the Remi and EPEL RPM repositories



If you haven’t already done so, install the Remi and EPEL repositories



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



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



Enable the REMI repository globally:



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



Under the section that looks like [remi] make the following changes:



[remi]
name=Remi's RPM repository for Enterprise Linux 6 - $basearch
#baseurl=http://rpms.remirepo.net/enterprise/6/remi/$basearch/
mirrorlist=http://rpms.remirepo.net/enterprise/6/remi/mirror
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-remi



Also, under the section that looks like [remi-php55] make the following changes:



[remi-php56]
name=Remi's PHP 5.6 RPM repository for Enterprise Linux 6 - $basearch
#baseurl=http://rpms.remirepo.net/enterprise/6/php56/$basearch/
mirrorlist=http://rpms.remirepo.net/enterprise/6/php56/mirror
# WARNING: If you enable this repository, you must also enable "remi"
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-remi



Type CTRL-O to save and CTRL-X to close the editor



3. Upgrade PHP 5.3 to PHP 5.6



Now we can upgrade PHP. Simply type in the following command:



yum -y upgrade php*



Once the update has completed, let’s verify that you have PHP 5.6 installed:



php -v



Should see output similar to the following:



PHP 5.6.14 (cli) (built: Sep 30 2015 14:07:43)
Copyright (c) 1997-2015 The PHP Group
Zend Engine v2.6.0, Copyright (c) 1998-2015 Zend Technologies



You’re done!
