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, $errline ) {
throw new ErrorException($errstr, 0, $errno, $errfile, $errline);
}
set_error_handler("exception_error_handler");
$iVar1 = 10;
$iVar2 = 0;
try {
$iVar1 = $iVar1 / $iVar2;
} catch (Exception $e) {
$iVar1 = 100;
}
//continue
echo $iVar1;
?>
Stay well

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
