Title: PHP: Read a browser cookie value Post by: Khushi on January 03, 2007, 12:37:55 AM Once your web application has set a cookie in a user's browser, it is a simple matter to retrieve that value in subsequent page requests. This recipe describes reading a value from a cookie in PHP.
After a cookie with a name of 'user' has been set in a previous page, the value can be accessed with the global array $_COOKIE like this: Code: $user = $_COOKIE['user']; Since this is a normal array, anything you can do to an array like iterate through it one value at a time. For debugging purposes, it is often useful to use this quick trick to see the whole contents of an array: Code: print_r($_COOKIE); |
