I agree. Not having "finally" is a language shortcoming.
One example I just ran into that made me cuss at PHP is this. Without finally,
one cannot use breaks in a try construct as break ends execution of the current
for, foreach, while, do-while or switch structure.
Code example:
do {
$lock = new PseudoLock();
try {
// do stuff
if (...) {
break; // this is a no-no without finally
}
}
catch(Exception $e) {
$lock = null; // release lock
throw $e;
}
$lock = null; // release lock
// Do more stuff.
} while (!$satisfied);
Note how the inner break will cause both resource lock release attempts to be
skipped. If the finally construct existed, the break would first pass through
the finally where the lock can be released, and then pass out of it's loop
structure. That's how it works in other languages.

Description:
------------
A previous thread for a request to add "finally" support for exceptions was
relatively quickly killed in what seemed, to me, the beginning of a potentially
useful thread (http://bugs.php.net/bug.php?id=32100) and I would like to
re-open it. The original requestors comments rings true for many of us
developing PHP.
FWIW: I heartily agree that "finally" should be implemented in some (hopefully
near) future version of PHP.
