Creating Cookies using PHP Next Code

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

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

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

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

<?php
setcookie("uname", $name, time()+36000);
?>
<html>
<body>

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

</body>
</html>

---------------------------------------------------------------------

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.

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

<html> <body> You are not logged in! </body> </html> <a target="_blank" href="http://www.phpfreecode.com/">PHP Free Code</a>
