Well, consider:
function foo() {
try {
// ...
} catch (Exception $e) {
// ...handle it...
return false;
} finally {
// ...clean up...
}
// ...continue doing whatever...
return true;
}
The cleanup code is always to be executed, the method should of course
not continue in case an exception was caught.
OK, I could write:
function foo() {
try {
// ...
} catch (Exception $e) {
// ...handle it...
}
// ...clean up ...
if ($e) return false;
// ...continue doing whatever...
return true;
}
so all it boils down to is, I guess, syntactic sugar.
