I am running OSX Server 3.x under Mavericks, mainly to use as Time Machine service for the other macs on my network. First question, I want to have PHP 5.6 with various extensions, which don't appear to be included with 10.9 nor with OSX Server. The web service in OSX Server has a checkbox to enable PHP. Ok, but where is that being used from? Is OSX Server providing some version of PHP somewhere, and if so where it is kept in the file system? A particular PHP based portal I want to use needs some PHP extensions. Installing the full and latest php5.6 puts PHP into a new place, user /usr/local/php5. But whatever OSX Server is doing it appears to be using some other distribution of PHP from somewhere and I guess has its own configuration for apache to use from that other place, wherever it is... Does anyone have any information about this..or suggestions about whether I should just turn off this service in OSX Server and install or configure apache more directly as if OSX Server isn't there, or how I can update PHP for use within OSX Server's web service? I'm also going to ignore OSX Server's FTP and use pure-ftpd. There is nothing else in OSX Server I plan to use, I really only need it for Time Machine...so I wish there was a lighter weight way to do that, but it appears there is not.
