It may be so that you can use exceptions as a sort of goto mechanism.
And from some perspective you may even find some similarities. However,
exceptions weren't invented for this purpose. (And they aren't
introduced into PHP for this reason.)
The main difference is that exceptions work with the *instance* of your
code. (Enable you to fall back to some place in your OO structure.) Goto
can't do that.

No, they are not. If you don't purposedly abuse it, exceptions are a

jump around the code.
How is that different from "goto"?
And if you can jump through 80% if your code via an exception while you
unwind the stack it might be ordered but you tell me that you know whats
going on. For all intends and purposes it will be just as random, with
the difference that you can search for the goto much better than for the
exception handler.
Anyways I have made my case and you have made yours. We can now choose
to ignore eachother :-)
