Disply php errors when using Zend framework

Question

Hey SO folk,

I've been using Zend Framework and just living with this problem for a while, but it's now just gotten too annoying so i'll send the question out to you.

There are certain problems within the Zend framework that Zend can recognize (such as calling a nonexistent controller), and will send that problem to the ErrorController. I've got that working fine.

There seem to be some problems that Zend Framework will fail and display the error through php, like if a certain function doesn't exist or something. Those I can see and fix.

Sometimes though, Zend won't fail, but it will also just send out an empty response. I will get a blank page. They layout doesn't show up, there's no code, there's no nothing to give me an idea of what's gone wrong. Last time, there was a require() that failed. I had to manually figure this out with no feedback.

Have any of you experienced this? Do you have any advice on how to get these errors to show? Any help would be appreciated!

Answer 1

The internal error handling of the framework's MVC components can only trap Exceptions, not PHP errors.

To assist in debugging during development, you can use the standard:

error_reporting(E_ALL|E_STRICT);
ini_set('display_errors', 'on');

Also, if you're using the new Autoloader included with 1.8, use:

Zend_Loader_Autoloader::getInstance()->suppressNotFoundWarnings(false);

To allow failed include/require statements to be issued.

For others coming across this question: I changed the following line in configs/application.ini

resources.frontController.params.displayExceptions = 0

To:

resources.frontController.params.displayExceptions = 1

This allowed me to see the full Exception, including stacktrace.
