php mysql suse 9.2

I am trying to install/use an application that access mysql using apache2/php/pear. SuSE 9.2. When php/pear try to access mysql, only a line with command mysql://asteriskuser:xxxxx@localhost/asterisk is displayed on a blank screen on the browser as a result. It seems to me that a link between apache2/php and mysql is missing. Any hint?
