PHP version on Ubuntu Server 14.04.4 LTS

Question

I would like know what specific version of PHP is installed* on stated Ubuntu server. I have read that 14.04.4 upgraded to PHP 5.5, however I need to know if the PHP version is >=5.5.9.

I have failed to find any information regarding the specific version (with the last number), I presume It's because the distributed PHP is beign updated, and thus it is not in Ubuntu release doc.

Thank you

*without manual updates, "out of the box"

Solution

At http://cdimage.ubuntu.com/releases/14.04.4/release/ there are ".list" files with the list of included packages in "Ubuntu 14.04.4 LTS (Trusty Tahr)". As is explained in the "Ask Ubuntu" answer, by the user g_p, to the What is the point of the ".list" files on the releases.ubuntu.com pages? question, those .list files "(...) lists all the files and packages present in the iso file."

The relevant ".list" file for the files and packages contained in the Ubuntu Server 14.04.4 LTS (I assume that you're talking about the 64-bit version) ISO is http://cdimage.ubuntu.com/releases/14.04.4/release/ubuntu-14.04.4-server-amd64+mac.list

By opening that ".list" file, we see that the PHP (PHP5) ".deb" packages listed are in version 5.5.9 (the version in the "php5" package itself is probably the best indicator). So, "5.5.9" would be the version included in that release.

Below, for reference, I include some of the packages included in that ".list" file:
