How do I find out how PHP was installed

  • 772

Is there a way to work out if PHP was installed as part of a generic apt-get package, compiled from source or installed some other way on Ubuntu?

I need to recompile it with some more options and I want to try and follow the correct upgrade path.

ubuntu php

    You can check if the package is installed with:

     dpkg -l |grep php

    and can check if the files on your system is consistent with the package with

     debsums packagename

    from this you can have some clues about the origin of the package.

  2. you may want to run as root

    root@machine:~# dpkg -l php5 (or whatever version you have)

    if php was installed using packet manager, this command will retun some thing like 

    root@machine:~# dpkg -l php5
