PHP-Interface on Win2k - Mailing list pgsql-interfaces

Hi

on my Win2k is PHP3 and on the Linux box is PostgreSQL7.0.2 installed.
Unfortunately I found nowhere the source or binary for the Postgres-
Extension for PHP3 (it should be called "php_pgsql.dll").
So phpPgAdmin doesn't work ;-(
Does anyone know where I can get the .dll or doesn't even 
exist any solution for PHP3 and PostgreSQL on Win2k (for PHP4?)?

Thanks
