all code
1. never use registered globals.
2. do not use magic quotes. they are worthless and often get in the way. use mysql_real_escape_string() or similar functions as necessary.
3. in php-only files, omit the closing php tag. this ensures that the file will not print a new line at the end of the file. this is important to ensure that you can print headers, set cookies, and print doctypes properly.
distrubuted code (including all open-source projects)
1. never use short-open tags.
2. undo magic quotes at the beginning of every script (see example two, disabling magic quotes at runtime ).
php environments
1. disable register_globals.
2. disable magic_quotes_gpc.
3. don't display php errors in production environments.

pro
I installed python.
That's a good PHP tip.
I have been known to offer sound advice on occasion.
Can you please explain that tip to my boss by the way? He insists on PHP :-(
