Hi there. I've used the Search here on the forum, and found this: I'm trying to installl a phpBB3 forum hosted on my server. I have already installed apache, whicch came with php. I don't know which php version is installed (how can I see it on a Linux box?), and I've installed MySQL, created a database and a username. However phpBB doesn't recognize the MySQL databases and says MySQL is unavailable. So i presume my php version is 5, because as I read there's a small problem with MySQL and PHP5. So how can I see my php version? (debian linux computer) How can I recompile it? It was installed with apt-get, so I can't configure it while installing. Can I enable MySQL after it is installed?
