Php Cookies

How to Create a Cookie?

Syntax

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

Examples

In the example below, we will create a cookie named "user" and assign the value "Alex Porter" to it. We also specify that the cookie should expire after one hour:

<?php
setcookie("user", "Alex Porter", time()+3600);
?>
<html>
.....

You can also set the expiration time of the cookie in another way. It may be easier than using seconds.

<?php
$expire=time()+60*60*24*30;
setcookie("user", "Alex Porter", $expire);
?>

<html>
.....

In the example above the expiration time is set to a month (60 sec * 60 min * 24 hours * 30 days).
