New Comment:
No, there is a difference between definition and assignment. The
variable is overwritten by the static-call during compilation. The value
is only assigned when the assignment is actually done.
In Jakub's last example, the code never hits the assignment statement.
In the original report, the "static $storage" definition is done twice,
and during the 2nd time the original $storage static definition is
destroyed. The static fetch in the return statement will therefore not
work. I'd say this should be documented...
It wouldn't be hard to add a notice for this though.

If static variables are resolved in compile time then
<?php
function storage($key) {
return $storage;
static $storage = array('a' => array('x', 'y'));
}
var_dump(storage('a'));
?>
should give an expected result.

It's the same as
<?php
exit;
class Test { }
?>
The class will be still declared, even though there is an exit
statement before the declaration. It doesn't mean that it's "executed",
because there is a big difference between "execution" and "compilation".

Hint. If you doc this please doc everything as well that executes at
compile time. It will be a very interesting handbook page...

see: http://php.net/return
"the return() statement immediately ends execution of the current
function"
(It's already documented.)
