Sounds a bit overly complicated! But an interesting solution.
Not that complex though, it's only a matter of iterating through $_COOKIE
and resetting each one with a known expiry time (strtotime('+10 minutes
and 20 seconds')). You could do this in a single file and automatically
use it on every page using php_value auto_prepend_file in the Apache
virtualhost.
It seems strange that there's no method in PHP for obtaining the cookie
expiry time.
It's not really strange, if you examine the HTTP spec (or watch HTTP
headers using Firefox's Live HTTP Headers) you'll find the browser doesn't
send back the expiry date to the server, only the name and value.
Therefore it's not strange that PHP can't obtain the information, it's
never told (and it can't just remember what it set because it could have
been changed with Javascript or by editing the cookies.txt file).
Ah well. In the mean time I have stuck with the 'storing
expiry time in another cookie' method. Suppose I could add a Java Script
function to check the values every second to produce a real time 'time
left until log out' counter.
Many thanks for the response!

You're welcome.
Cheers,
Andy

Examples

Example #1 $_COOKIE example

Php
<?php
echo 'Hello ' . htmlspecialchars($_COOKIE['name']) . '!';
?>

That covers the basic usage of cookies in PHP, but just what exactly are cookies and how do they work? Let us walk through more examples, read on! Ⓘ I have included a zip file with all the example source code at the start of this tutorial, so you don’t have to copy-paste everything Or if. In PHP setcookie function accepts argument like this: True/False Setcookie (name, value, expire, path, domain, secure) Path = ‘/’ will set cookie for entire domain. Path = ‘foo’ will set it for foo directory and subdirectory of ‘/foo/’. In a nutshell, when setting a cookie value, I serialize it, gzcompress it, base64 encode it, break it into pieces and store it as a set of cookies. To fetch the cookie value I get the named piece then iterate through piece names rebuilding the base64 data, then reverse the rest of the process. The only other trick is deleting the pieces correctly. A cookie is a text file saved to a user's system by a Web site. This file contains information that the site can retrieve on the user's next visit, thereby allowing the site to 'recognize' the user and provide an enhanced set of features customized to that specific user.

The above example will outputsomething similar to:

Notes

Note:

Php Get Cookie

This is a 'superglobal', orautomatic global, variable. This simply means that it is available inall scopes throughout a script. There is no need to doglobal $variable; to access it within functions or methods.

Cookies with the same name the first cookie is used. Clients will send cookies with longer path before cookies with shorter path. This comes from RFC 6265 which says 'Cookies with longer paths are listed before cookies with shorter paths.'. So you get the best matching cookie for your current request.
