PHP security is an extremely broad topic, so it's difficult to answer
your question directly.
The biggest rule of thumb is NEVER trust information coming from a
client. Check and re-check all input, use pattern matching to strip
out characters that don't belong there, etc. Lack of input validation
is one of the biggest and most common developer mistakes out there.

Also, make yourself intimately familiar with the information on this
site. ;)

This is where you can read up on past mistakes vendors have made
(Bugtraq/Vulnerabilities), and also several security-related articles
on a variety of topics like XSS, SQL injection, etc.
(Library/Infocus).
Hope that helps get you started anyway...
