Error Handling Ideas from PHP mag

Posted on 06 August 2003 by Demian Turner

If you are not fortunate enough to be a subscriber to PHP magazine, you may want to take a look at this great error handling class presented last issue by Peter James.

The class introduces a few interesting programming ideas, like inner functions and using them to override PHP’s default error handling.

At first glance the inner function idea seems like a lot of
work to get around a feature built into PHP.

He could have just done:
```
function start_handler() {
   set_error_handler(array('ErrorHandler','error_handler'));
}
```
Of course he has an excludes array and a line number counter
which are static parameters so you may need to revise the code
to:
```
function start_handler() {
   set_error_handler(array(&this,'error_handler'));
}
```
Someone tell me why I need an inner function and two
globals?

Methinks some people need to spend more time reading the
(very incomplete!) documentation at PHP.net!

If you read the documentation in the class *and* on php.net for set_error_handler(), you will see that it did not accept anything but a standard function name before php 4.3… And this was written well before php 4.3.

Thanks,
Pete.
