Note that throw is a language construct (see http://php.net/manual/en/reserved.php) not a
function, which prevents you from using compact expressions such as:
<?php
function inverse($v) {
is_numeric($v) or throw new BadArgumentException();
// ... snip
}
?>
So, you can emulate it with a little wrapper:
<?php
function toss($e) { throw $e; }
function inverse($v) {
is_numeric($v) or toss(new BadArgumentException());
// ... snip
}
?>
Because the Exception is instantiated in the same place, the stack trace inside the exception is the
same.
