Installing DPKG onto VPS2

[mofolo]

Hi There,

I need some help installing the command DPKG onto my VPS.

When I run Dpkg in SSH it returns:

-bash: line 7: dpkg: command not found

What are the steps to installing dpkg on my vps (it's running CentOS)?

I also need to use Dpkg from my PHP code.
eg:
exec ("dpkg -i file.deb")

Thanks.
