The most common scenario for try / finally is to release some
resources regardless of whether or not an exception occurred.
For example:
try {
$r = new Something();
$r->doStuff();
} finally {
$r->cleanup();
}
So $r->cleanup() will run regardless of whether or not the try block
code throws an exception.
The "ugly hack" cited catches the exception. You could re-throw it but
that may not be the desired behavior. You might want to catch one type
of exception and yet re-throw another. That's more logic you have to
consider. With a finally clause it's very clear that that code is to
be executed regardless of what happens (sans program exit).
A finally clause would be a good addition to PHP.
