Hullo List, I installed php-4.2.1 last week by downloading and configuring the tarball, using the - - with - options. The system is still using the old version, however: php-4.0.6. Because I've upgraded postgresql using apt-get to v7.2.1 I needed to recompile php, you see, and so thought I may as well grab the latest version whilst I was at it. How does the system know which of the php's to use? If I brutally remove the v4.0.6 directory I assume php won't work at all. I feel like I've gone back a year in time, all this newbie fumbling about. Does my question make any sense at all? Thanks, Jenny.
