挂钩PHP运行时

Question

Is there any way in php.info (or other config file) for me to indicate a script to be run every single time PHP is invoked?

I'm interested in mapping HTTP requests for a particular page to a Controller class representing that page, similar to how a lot of MVC framework (like CI) work.

For instance, the user clicks a link that should map to /webroot/some/url/widget.php, but rather the /webroot/app/mvc/controllers/WidgetController.php class is what gets invoked instead.

To do this, I figure MVC framework like CI have figured out a way to "hook" the PHP Runtime by running a script that runs and says "oh, the request is for widget.php, but we want to actually run the WidgetController.php object."

Any ideas/thoughts/suggestions/concerns?

Thanks!

You need a router, and apache mod_rewrite or equivalent. You set up mod_rewrite to send all requests to a single file, such as /index.php. The router then looks at the request URL and determines which controller file to load and which method to call. Pretty much any MVC framework has this functionality built-in, and they all work pretty much the same.
