No it is not, in your application you can still simply catch Exception to be
independent of SPL since the InvalidArgumentException class extends the
Exception class. But by using nested Exceptions you can catch them
independently. Else you would have to catch every Exception, parse the error
message or trace to see wether it was a problem while calling the
function/method or some code inside the function/method went wrong.
<?php
function foo() {
$bar = ....;
try {
call_with_wrong_parameter($bar);
} catch (InvalidArgumentException $e) {
// bad function call...
}
}
try {
foo();
} catch (Exception $e) {
// any other exception
}
?>
I'd like to see something like what Sebastian suggested. And imho it wouldn't
really be a bc-break since an uncaught exception is fatal, too.
