PHP: Session Timeouts

Chris — Thu, 26 Nov 2009 22:31:50 +0000

Defining session timeout thresholds for PHP scripts is a security “must”. I recommend that you consider the purpose of your script before applying a session timeout function. For instance, if your site has a secure login and security requirements, it’s important to include the timeout function. However, it’s often an inconvenience to end-users.

Use the code below to create a function which can be used to implement a secure timeout threshold.

{code type=php}
/* Set timeout threshold to 10 minutes (600 seconds) */
@session_start();
$timeout = 600;
$_SESSION["expires_by"] = time() + $timeout;
{/code}

“Lock Desktop” – New Mac OS X App

I’ve uploaded one of my first applications for a Mac. It’s extremely easy to use. The tool allows you to lock your desktop when you’re away from the computer and requires a password when you get back. This is something you can run on demand, instead of waiting for a screen-saver, or logging off. Lock Desktop 1.0 even keeps your programs running in the back.

Mac OS X – Application that will “lock” desktop. This feature was available on my PC and allowed to leave my workstation and ensure that my desktop remained safe. This application runs an Automator script to lock the desktop.
