Description:
------------
---
From manual page: http://www.php.net/function.spl-object-hash
---
Documents say parameter can only be object but callable is also allowed and the docs should be updated to reflect it.

Test script:
---------------
$callable = function() {
    return 'test';
};
$result = spl_object_hash($callable);
// $result = '000000002ddd793a0000000047573d56' for example
print $result .PHP_EOL;

It can only be callable if the callable is an object: $callable in this case is a Closure object, so spl_object_hash() can deal with that. spl_object_hash() would still fail with any callable that isn't an object, such as 'functionName', or [$object, 'methodName'].

Sorry wasn't thinking about that you are right it doesn't work if you use something like ['test','test'] instead.
