dist-upgrade means upgrading to a new release. This is not what you
want. If you find some time, read apt-howto. Apt is so powerful, it's
really worth to dig into it.
http://www.debian.org/doc/manuals/apt-howto/ch-apt-get.en.html

This is what you need to do to get your system running:

Append the following line to your /etc/apt/sources.list
 deb http://packages.dotdeb.org stable all

Run the commands (in simulation mode!):
user at host:~$ aptitude update
user at host:~$ aptitude -s install php5

Notice that apt-get tells you, that some packages have been kept back.
This is because
a) Policy: the dotdeb repository comes with a higher preference than
standard sarge does, and
b) it delivers more actual php4/mysql4 packages than sarge.

To avoid this, use the pinning feature of apt to change your policy
(apt-howto chapter 3.10).

To get the actual policy, run
user at host:~$ apt-cache policy

Package Files:
 100 /var/lib/dpkg/status
     release a=now
 500 http://packages.dotdeb.org sarge/all Packages
     release o=packages.dotdeb.org,a=sarge,l=packages.dotdeb.org
     origin packages.dotdeb.org
 500 ftp://ftp.fu-berlin.de sarge/main Packages
     release v=3.1r6,o=Debian,a=oldstable,l=Debian,c=main
     origin ftp.fu-berlin.de
(...)

The highest priority number (100 / 500) wins.

Change the priority of the dotdeb packages in /etc/apt/preferences:

Package: *
Pin: origin packages.dotdeb.org
Pin-Priority: 200

Package: php5-cgi php5-common php5-mysql php5-gd
Pin: origin packages.dotdeb.org
Pin-Priority: 900

Now once again try to upgrade your packages:
user at host:~$ aptitude update
user at host:~$ aptitude -s install php5

No more packages kept back? Install php5!
user at host:~$ aptitude -s install php5-cgi php5-common php5-mysql php5-gd
