I am new to PHP. Trying to install it and PostgreSQL 8.0 on Slackware Linux 10.0.0 . I am getting the following error out of Apache: Fatal Error: Call to undefined function: pg_connect() After browsing your web site, I found http://us2.php.net/pgsql . But am unable to proceed because I am not sure what to do. Specific questions: (1) How do I determine what version of PHP I have? Browsed PHP directories, but couldn't find it. (2) The information I found said I could use a "shared object module" and/or (I think) alter php.ini . I don't think this is hard to fix, but I need to find a blow-by-blow of what to do. Can somebody help me?
