SQL Anywhere and PHP connection

Hi,

I am trying to connect to a SQL anywhere database, but its not working.

I have done the following:

1) Installed SQL anywhere 16, and created a database/personal server.

2) Installed WAMPSERVER

3) Added the dll file to the ext directory of www

3) Added the dynamic extension

But when I go to localhost/phpinfo.php, the sqlanywhere extension is not there, and I get a fatal error when running the code.

Please help...
