The thing that is puzzling me is that E_ERROR errors i.e. fatal errors don’t seem to be being caught by _exception_handler at all. It’s not just that show_php_error isn’t being called, it looks like the function just isn’t being called for them. This is obviously a problem as it means that they aren’t get handled by show_php_error or logged. For example if I deliberately mistype $this->load->views('foo'); in a controller, the handler doesn’t get called. Any suggestion about error handling would be much appreciated, thanks! php codeigniter share|improve this question edited Feb 8 '13 at 18:25 Tom Walters 9,26343057 asked Feb 8 '13 at 17:47 troy 507924 I think it may be an issue with PHP itself without being able to test it. If you see php.net/manual/en/function.error-reporting.php#70126 you'll see that in this case, an E_ERROR causes a similar effect to what E_
for us to know. The idea was that whenever such an exception occur on production we should send an email http://thecancerus.com/simple-way-to-add-global-exception-handling-in-codeigniter/ to developers mailing list so that someone can investigate it. As usual I http://programmers.stackexchange.com/questions/133335/handling-errors-in-php-when-using-mvc did a quick google search and i found two forum posts in CodeIgniter and one on stackoverflow, but they all fall short as CodeIgniter does not set’s any default exception handlers they way it sets the native error handler. So here is a quick tutorial on how you can do error handling that. First of all you need to setup a hook, so put following code in hook.php file in config folder. $hook['pre_controller'][] = array( 'class' => 'ExceptionHook', 'function' => 'SetExceptionHandler', 'filename' => 'ExceptionHook.php', 'filepath' => 'hooks' ); Now I am using pre_controller hook as I wanted to use $CI object which is available at this stage. Now put the code shown below in the error handler codeigniter file named ExceptionHook.php in your application’s hooks folder. Also if you need to capture and email native PHP errors, you can do so by extending the Exceptions library as shown in the code below. While I have used the simple PHP mail function in the example above, you can use CI's mail library as well. If you have any doubts feel free to ask in comments below.

I've never been good at handling errors without it getting messy. My main concern is when returning errors to the user. Is it good practice to use exceptions and throw/catch exceptions rather than returning 0 or 1 from functions and then using if/else to handle the errors. Thus, making it easier to inform the user about the issue. I tend to go away from exceptions. My Java tutor at university some years ago told me "exceptions shouldn't be used in production code it's more for debugging". I get the feeling he was lying. But, an example, I have code that adds a user to a database. During the process more than 1 thing could go wrong, such as a database issue, a duplicate entry, a server issue, etc. When an issue happens during registration the user needs to know about it. What's the best way to handle errors in PHP, keeping in mind that I'm using an MVC framework. php mvc error-handling share|improve this question edited Feb 4 '12 at 21:15 Thomas Owens♦ 47k12117200 asked Feb 4 '12 at 20:38 James Jeffery 16113 add a comment| 3 Answers 3 active oldest votes up vote 13 down vote Is it good practice to use exceptions and throw/catch exceptions rather than returning 0 or 1 from functions and then using if/else to handle the errors.
