Question:

The php version on my VPS is out of date. How do I update it?

Answer:

Using the OS vendors normal update command can get you some updates (but perhaps not what you want – see below). For example on RedHat/CentOS run:

yum update php

However usually the OS vendors versions are not the latest. The update them to patch security issues but many times are far out of date from what you may require.

To update RedHat/CentOS to a newer php run these commands:


yum erase php-pdo php-xml php-mysql php php-common php-cli php-gd php-mbstring php-devel

yum install php53-pdo php53-xml php53-mysql php53 php53-common php53-cli php53-gd php53-mbstring

/sbin/service httpd restart

A note:

These are “unofficial” RPM’s as RedHat only official supports a particular (semi-old) version and backports security fixes to it – good for large corporate users but not so great for active developers). However the RPMS’s above are widely used in the community and most developers view them as trustworthy (just important to note that they are not actually from RedHat).
