This is a great set of tips. Number one, mein gott, number one... If half the people who had questions tried google before ripping off an email or phone call, then perhaps we wouldn't need this site:

Seriously though, I would strongly caution against leaving a phpinfo() page out there for any length of time. The info from phpinfo can give a malicious person information that makes your server an easy target. And even if you don't care about your project so much, if you have shared hosting (most do) you are also exposing your server-neighbors.
