How do I set a cookie that never expires?

[rapmonkey]

What do I need to set the time to?

You can't. Just set it for some time very far into the future (2-3 years will be perfect, cookies will be deleted before that).

for the time part on the setcookie(); use this:

time()+60*60*24*29.5*12*24

that will expire in exactly 24 years... 😃
