  Unless you know what you are doing or what to look for, the best advice is
to nuke and pave (reformat the harddrives, reinstall the operating system,
reload the websites).

  In any case, you'll want to disable PHP and all logins until you have
audited all the sites, PHP scripts and users of the box.  Make sure all
passwords are changed.  Only then would I re-enable PHP.

  Also, check the startup scripts and shut down any service you don't need! 
Not only do they suck up memory (and/or swap space) but if they offer any
network services, that's just another way to be hacked.  If you are unsure
of what a startup script does, use Google.

	you can do ... )
