Cookies - set but don't stay

[Kol]

😃

I am using this code to set a cookie:

setcookie("cookie", $UID);

It seems to set fine, and i am able to retrieve that data afterwards (from multiple pages, so i know it has set) using this code:

$var = $_COOKIE["cookie"];

I would like the cookie to stay forever, but at the moment it doesnt last very long (i dont know exactly how long) but if i leave it for about 20 minutes, when i come back to it, it has gone.

Anyone know what i am doing wrong?

Thank you!

Check the manual fot this issue. You will see that the 3th parameter you can give with setcookie() is the expire parameter.

setcookie ("cookie", $UID,time()+86400);

Will set a cookie for a day.

BTW if you, for instance, set a cookie for an hour it may expire on the fly because your server is in new york and your visiter is in london. London is ahead 4 hours if i'm not mistaking.

Other solution:

If your able to alter the php.ini file you can set session.cookie_lifetime = 0
This way the cookie will expire at the moment the browser is reset.

PS: You can use ini_set() to do this:

ini_set ("session.cookie_lifetime", "0")

Don't know if this works, didn't test it.

This will set a cookie with an expiry date of 1 year from todays date:

setcookie("cookie",$UID,time()+60*60*24*364);
