There's no other way than manual parsing depending on the type.
I didn't add support for objects, but it's very similar to the arrays one; you just need to do some reflection magic to populate not only public properties and to not trigger the constructor.
EDIT: Added support for objects... Reflection magic...
function unserializeDump($str, &$i = 0) {
$strtok = substr($str, $i);
switch ($type = strtok($strtok, "(")) { // get type, before first parenthesis
case "bool":
return strtok(")") === "true"?(bool) $i += 10:!$i += 11;
case "int":
$int = (int)substr($str, $i + 4);
$i += strlen($int) + 5;
return $int;
case "string":
$i += 11 + ($len = (int)substr($str, $i + 7)) + strlen($len);
return substr($str, $i - $len - 1, $len);
case "float":
return (float)($float = strtok(")")) + !$i += strlen($float) + 7;
case "NULL":
return NULL;
case "array":
$array = array();
$len = (int)substr($str, $i + 6);
$i = strpos($str, "\n", $i) - 1;

if ($str[$i + 1] == '"') {
// use longest possible sequence to avoid key and dump structure collisions
$key = substr($str, $i + 2, - 2 - $i + $i = strpos($str, "\"]=>\n ", $i));

(Here are a lot of "magic" numbers when incrementing string position counter $i, mostly just string lengths of the keywords and some parenthesis etc.)
string(8) "Foo"bar"and other weird edge cases, it's going to make it relatively messy to implement in a reliable manor... If there are elegant solutions, I'd love to see them. But realize that most fully working solutions will likely be rather lengthy and have a fair bit of logic inside... – Guadalupeguadeloupevar_export()? – Canon
