Trouble with PHP3 MySQL

Hello - Yes, I'm one of those people with annoying questions! I had installed the Apache 1.3 with PHP3 support package that's available on the ports tree for FreeBSD 3.4-STABLE. Orignally I was able to write code that worked well with my local MySQL server. Then I attemped to upgrade to PHP4, which for some wierd reason kept my apache server from starting. Upon downgrading back to PHP3 I am no longer able to get MySQL working again. I have attempted to completely reinstall Apache and the PHP3 module but I consistantly get: Fatal error: Call to unsupported or undefined function mysql_connect() in auth.htm on line 34 (This previously worked fine!) Thanks for your help. I'd appreciate it if you could respond directly to my email box: edgar@bala.qc.edu, because its difficult for me to read through the entire list everyday. :)
