How do I see if a package is installed in Debian?

In CentOS I would use the following command:
For Apache

#rpm -q httpd

For MySQL

#rpm -q mysql-server

for PHP

#rpm -q php

How do I do the same in Debian?

dpkg --get-selections | grep php

dpkg --get-selections | grep php

That works thanks.

You could always shorten that up and use -l (list)...

dpkg -l | grep php

I do:

apt-cache policy php5

Shows you the installed version (if any) and also what version is on the repo...
