try running any of the following at the command line

php -i

to get alot of info or

php -v

to just get the version information

It should give you all information you need about the php install.

+1 php -v was a lot faster – hyperslug Aug 24 '09 at 9:10
Thx, this worked :-) php -i | grep 'PHP Version' gave me the answer – Roland Aug 24 '09 at 9:12

You can make an index.php file with

<% phpinfo() %>

this 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 – Phoshi Aug 24 '09 at 10:56
Ah, right, I have a habit of using ASP tags. – hyperslug Aug 24 '09 at 21:26
On any PHP website one can often see the version in the X-Powered-By header 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 a tar command.) – Arjan Sep 14 '09 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):

  1. Find the full path to the file if not known, such as for an executable in $PATH:

    type -path awk

  2. Find the name, including version, of the package containing the file:

    rpm -qf /usr/bin/awk

  3. 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'
