Can't use MySQL 5.x Client with PHP 5.x

["Andy Blank" <mailinglist@blankster.info>]

Hi,

This is my first mail to this mailinglist and my last hope.
I looking for a solution for my "problem" since a very long time
but I don't get it.

I've installed PHP 5 and Mysql 5 (Client
and Server) but PHP uses still the 4x client... What can I do to solve
that problem?

My second problem is that I want to use mysqli
and I saw backports.org doesn't offer this PHP-module. Can anybody tell me
what I can or where can I get it?

I've installed the following
packages from backports.org:
libapache2-mod-php5     5.2.0-8~bpo.2
libmysqlclient15off    
5.0.30-1~bpo.1libpopt0        1.7-5
