Php Code: Creating Cookies using PHP

How to Create a Cookie
The setcookie() function is used to create cookies.

Note: The setcookie() function must appear BEFORE the tag.

setcookie(name, value, expire, path, domain);

The following example sets a cookie named "uname" - that expires after ten hours.

setcookie("uname", $name, time()+36000);

A cookie was set on this page! The cookie will be active when the client has sent the cookie back to the server.


How to Retrieve a Cookie Value
When a cookie is set, PHP uses the cookie name as a variable.

To access a cookie you just refer to the cookie name as a variable.

Tip: Use the isset() function to find out if a cookie has been set.

The following example tests if the uname cookie has been set, and prints an appropriate message.
