It's the reason why I can't stand exceptions in PHP, we talked about this a
bunch at our meeting on Wednesday.
You still have to suppress the error through one of several methods (using @ or
custom error handler that does not display it)
AND then you have to throw an exception manually.
I fact, I don't even know how you would write one for that type of error. Live
to hear some more input.

Yup.
That bit of obvious error-generating code was also just an example of
something that would definitely generate an error/exception, since current
actual issue is that am meant to be using/operating within someone else's
sort of containing framework/wrappers, and means can't always be sure what
code will work, or generate an error, etc., and just don't want to have to
specifically check for all function definitions using function_exists(),
etc. etc., but anyway.
Also just that, in most other languages, there is some or other, relatively
simple way to handle something like a try - catch exception - and just
perform some other action methodology, so was just wondering...?

Ok, and, along the lines of this, I also get the following error/exception
when I try to determine if a function is defined using function_exists():
Fatal error: Undefined class constant 'getUserDepartment' in
/var/www/business/products/attendance.php on line 52
The other difference there is that to call the getUserDepartment() function,
I need to refer to it via another parent/wrapper object:
Security::getUserDepartment()
And, this, again means that I can't really, at runtime, determine if can
call that function, or not.

I'm confused.
Can't you just use method_exists(array("Security", "
getUserDepartment"))?
If that throws an error because of class, then just suppress it (@).

The problem is noted here
(http://www.php.net/manual/en/language.exceptions.php):
>Internal PHP functions mainly use Error reporting, only modern Object
oriented extensions use exceptions. However, errors can be simply translated
to exceptions with >ErrorException.
One possible solution (noted here:
http://www.php.net/manual/en/class.errorexception.php) is to add this at the
beginning of your code:
function exception_error_handler($errno, $errstr, $errfile, $errline ) {
throw new ErrorException($errstr, 0, $errno, $errfile, $errline);
}
set_error_handler("exception_error_handler");
That will catch your divide by zero error.

Ok, thanks - now that php.net is back online, that page sorted out a form of
solution - check out this relatively simple source code:
<?php
function exception_error_handler($errno, $errstr, $errfile, $errline ) {

Subject: RE: [PHP-WIN] Simple error handling/catching/avoidance
The problem is noted here
(http://www.php.net/manual/en/language.exceptions.php):
Internal PHP functions mainly use Error reporting, only modern Object
oriented extensions use exceptions. However, errors can be simply
translated
to exceptions with >ErrorException.
One possible solution (noted here:
http://www.php.net/manual/en/class.errorexception.php) is to add this at
the
beginning of your code:
function exception_error_handler($errno, $errstr, $errfile, $errline )
{
throw new ErrorException($errstr, 0, $errno, $errfile, $errline);
}
set_error_handler("exception_error_handler");
That will catch your divide by zero error.

Oh, I agree and working with C# makes me really understand how limited the
PHP exception / error handling process is.

Yup.
That bit of obvious error-generating code was also just an example of
something that would definitely generate an error/exception, since current
actual issue is that am meant to be using/operating within someone else's
sort of containing framework/wrappers, and means can't always be sure what
code will work, or generate an error, etc., and just don't want to have to
specifically check for all function definitions using function_exists(),
etc. etc., but anyway.
Also just that, in most other languages, there is some or other,
relatively
simple way to handle something like a try - catch exception - and just
perform some other action methodology, so was just wondering...?

It's the reason why I can't stand exceptions in PHP, we talked about this
a
bunch at our meeting on Wednesday.
You still have to suppress the error through one of several methods (using
@
or custom error handler that does not display it)
AND then you have to throw an exception manually.
I fact, I don't even know how you would write one for that type of error.
Live to hear some more input.

Just wondering why the following code actually renders an error
message
instead of just then invoking the catch clause:
//start code
$iVar1 = 0;
$iVar2 = 10;
try {
echo $iVar2 / $iVar1;
} catch (Exception $e) {
echo "No division by zero allowed";
}
//end of code
