Setting up a maintenance page with Zend Framework

One of the things that smaller sites who don’t have a fully redundant setup or a relatively minimal deployment mechanism need to do when doing some kind of maintenance is put up an “Under Maintenance” page. That or there was some massive problem and you need to just shut down access to the site while you fix the problem. With that in mind I have written a very simple example that allows you to create a maintenance page that is configurable and requires no changes to your existing site. This example uses Zend_Application, but all of the code can be used in a pure Zend_Controller application by adding the plugin however you normally add plugins.

Friday Framework Highlight: Zend Framework MVC Request Lifecycle

Matthew wrote up an article on modules in Zend_Application and that got me thinking a little bit. When I have done training for Zend Framework, one of the things that mystifies students to some extent is the whole plugin architecture and where things can go. There has been several articles written about it, but they tend to use code to describe it. I was only able to find a small handfull of articles that used some kind of chart to describe what goes on. Not that that’s a problem, but I had found that when I drew out the request lifecycle that it helped the students understand it better.
