Mysql and php3 problem

[Gareth <gwalters@metz.une.edu.au>]

G'day all,
	I am having trouble getting php3 to recognize other librariies
in /usr/lib/php3/apache/ 
there is calendar.so  crypt.so  gd.so  mysql.so
but i get the following error message on trying to use any functions form
them

Fatal error: Call to unsupported or undefined function mysql_connect() in
/home/gwalters/public_html/example/index.php3 on line 8

I had a look /etc/mysql/my.cnf
and everything looks correct 
I am running potato with kernel 2.2.12

any ideas ???
