PHP globals

[sclewin]

Hi all,

I'm currently designing a page and I am making use of PHP. I have noticed more and more I am depending on making variables global in the functions I create. I find using global variables to be very easy to use and work well. My question is using globals in PHP evil at all. Are there any problems I could run into for using globals or are globals considered bad programming practice at all?

Theres always session cookies.

Thank you, but I would like to keep everything server side. It is for a PBEM game and the script will be run from a cron job.

globals shouldn't be any harm, since they act just like every other variable.

Cool, that was actually what I was hoping to hear.

Well, just to know, in PHP 6:
# Will not have register_globals;
# Will not have magic_quotes_*;
# Will not have safe_mode;
# Identifiers will be case-sensitive.

So, never use Register_globals. Since x10 is always up-to-date with PHP, when 6 comes in stable, these i told and some some will not work ;D
