Can A PHP Cookie Work On Firefox, But Not On IE or Opera?

One of my PHP scripts is setting a cookie that works great in Firefox, but mysteriously it doesn't work in IE (6 or 7) or Opera. Does that make sense?

I checked the cookie with a print_r function, which showed the entire cookie array on Firefox, but nothing on the other browsers.

My developer says he has had no problems.

Any thoughts?

There shouldn't be a reason for cookies to be unsupported by one browser. Perhaps you have disabled all or some cookies in the problematic browser?
i think each browser has its own setting whether u want to disabled or enabled cookies.. thus you might need to check whether your cookies is enable at IE or Opera.
