[Sean78Black]

To install, you need to use the extended storage of CentOS, it is EPEL and Remi repository.

Install EPEL repository

$ sudo yum install epel-release

If you can not use this command, you can install via RPM:

For CentOS 5:

$ wget http://dl.fedoraproject.org/pub/epel/5/x86_64/epel-release-5-4.noarch.rpm

CentOS 6:

$ wget http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm

CentOS 7:

$ wget http://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-5.noarch.rpm

After you download the RPM file above, use the following command to install:

$ sudo rpm -Uvh epel-release*.rpm

Remi repository

Remi repository is the repository for PHP on CentOS installation support PHP version 5.4 / 5.5 / 5.6 and PHP 7.

For CentOS 5:

$ wget http://rpms.famillecollet.com/enterprise/remi-release-5.rpm

CentOS 6:

$ wget http://rpms.famillecollet.com/enterprise/remi-release-6.rpm

CentOS 7:

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

After you download the RPM file above, use the following command to install:

$ sudo rpm -Uvh remi-release*.rpm

To select PHP version to install, you need to enable it in the repository Remi. Open and edit file /etc/yum.repos.d/remi.repo

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

You can see in it parts such as: [remi] for PHP 5.4, [remi-php55] fori PHP 5.5 and [remi-php56] for 5.6. to enable the version you want to install, edit “enabled=0” to “enabled=1“.

[B]enabled=1[/B]
gpgcheck=1

[remi-php56] # fori PHP 5.6

#baseurl=http://rpms.famillecollet.com/enterprise/6/php56/$basearch/
mirrorlist=http://rpms.famillecollet.com/enterprise/6/php56/mirror
# WARNING: If you enable this repository, you must also enable "remi"
[B]enabled=1[/B]
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-remi

That's all, you can use yum to install PHP-FPM and some PHP functions as follows:

$ sudo yum install php-fpm php-mysql php-gd php-mbstring php-pear php-xml php-xmlrpc php-devel

To install PHP 7, use the following command:

$ sudo yum install php70

To update PHP to a newer version, use the following command:

$ sudo yum update

Ok, whether you're using CentOS 5, you can still use the new PHP version.

Good luck!
