I'm running Centos 5 and I need to know what version of PHP I'm running, is there a command for this which I can run?

Try running the following at the command line.
To just get the version information:
php -v
Or to get a lot of info:
php -i
It should give you all information you need about the php install.

4Just be cautious that the CLI version of PHP (checked from command line) can be different from the one served by your webserver (shown by phpinfo()) Jun 4, 2014 at 11:14

You can make an index.php file with
<?php phpinfo() ?>

7this has the advantage of working on servers you don't have ssh access to, though personally I've always preferred <?php ?>, just for the futureproofing :P– PhoshiAug 24, 2009 at 10:56

2On any PHP website one can often see the version in the
X-Powered-Byheader in each PHP generated HTTP response. When you don't have SSH access, then sometimes phpshell.sourceforge.net can be used. (Though with much care, like one needs to check if a folder is writable before running atarcommand.)– ArjanSep 14, 2009 at 16:21 -
An answer was accepted, but another option on RPM systems (RHEL, Centos, Fedora, etc.) is to use the following:
rpm -q php
And while I'm at it, the general method for using RPM to find info on a package for any rpm-installed program or file is similar to this (for awk):
Find the full path to the file if not known, such as for an executable in $PATH:
type -path awk
Find the name, including version, of the package containing the file:
rpm -qf /usr/bin/awk
If desired, query for info from that package:
rpm -qi gawk
It's a bit trickier for packages installed and used by Apache since they may not be on $PATH, but you can start with something like:
rpm -qa | egrep -i 'php|awk'
Use
more /etc/php.ini
This will show you:
- Apache Version
- PHP Versions
- PHP Functions
- Various options regarding PHP
