1. That's the name of the cookie so you can refer to it on the next page.

2. That's the value(s) you want to store in the cookie

3. That's the lifespan of the cookie on a client's computer. You can make it live for 1 second or for weeks.

4. That refers to the page the cookie was created on.

5. That's the domain name that the cookie came from.

6. Err I don't remember..

Here's #1 explained a bit better. Say you want to keep track of everyone that comes to your page.. then you could make up a cookie called 'peopleCookie' or anything else for that matter... just some name that you will remember of so you can refer to it on another page.

BTW, when I say refer I mean access the data values in the cookie.

So no here's #2. Say the person entered his/her age and sex.. ie 22 and Male... then you could store the values in the cookie and then on the next page instead of asking the guy the same questions you simply get the info from the cookie called, in our case, 'peopleCookie' but it could as easily be called 'MonkeyBrains' it doesn't matter.. whatever YOU want.

Hope that helps.

Hi Swix, thanks for the help... you explained it very well on what are the duties of each code i made... however, how do you call the cookie into the other pages that i have?

for example i put this setcookie inside login.php:

setcookie("Myinfo",$value,time()+3600,"/~raffie/",".utoronto.ca",1);

how can i call this cookie into main.php, aboutus.php, moreinfo.php ?

Please help... thanks again Swix for helping me out

just type <?=$Myinfo?> or when an php script is already started
<?php
print ("$Myinfo");
?>
