PHP and Cookies

[Anon]

Hi,

I know how to set cookies: SetCookie("blah"); and I know how to set contents: SetCookie("blah","contents");

My question is:
how can I set variables in a cookie?

Example:
I want so set the variable $var1="okay" and several other variables in the cookie. Afterwards I want to change or add some variables. How can I do this?

And most important question:
How can I retrieve a certain variable from the cookie?

Thanks in advance!

Once you've set:
SetCookie("blah","contents");
you're having $blah="contents" in your script. So, you're accessing variable just by cookie name.
But be sure to set cookies later than any otuput is sent by your script! Anyway, you can find all in manual.
