It appears this is fixed in 5.5 but not 5.4.x, at least not as of 5.4.13, which
is
the latest to which I have access.
Is there any chance the fix will be back-ported to 5.4?

Hello. This is not really fixed. I still got this error on PHP 5.4.5. I don't
believe that the said fix wasn't released in six months, so something is wrong.
So, is this going to be reopen or should I file a new bug?

Hello. I'm experiencing this problem in Windows and Linux, PHP 5.4.4 and PHP
5.3.3. I argue it's not resolved again.
I wrote a demo at http://maisqi.com/outros/bugs/php/SplFixedArraySerialization
and I'd appreciate if someone else makes his own tests. Here is the demo source
code:
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>SplFixedArray Serialization</title>
</head>
<body>
<p>
An unserialized SplFixedArray loses it's element count, though it keeps
the
elements. This seems to be
<a href="https://bugs.php.net/bug.php?id=60560&edit=1";>Bug
#60560</a> all
over again.
</p>
<p>
This demo runs on a PHP 5.3.3 CGI under Apache and Linux. Also tested it
on a PHP 5.4.4 running as a Apache 2 module under Windows 7 32 bits,
with
same results.

Automatic comment from SVN on behalf of aharvey
Revision: http://svn.php.net/viewvc/?view=revision&revision=323408
Log: Add a __wakeup() method to SplFixedArray, thereby fixing serialising an
SplFixedArray object and bug #60560 (SplFixedArray un-/serialize, getSize(),
count() return 0, keys are strings).
------------------------------------------------------------------------

Quick fix is to store in serialized form internal array:
-------------------------------------
$sa = serialize($a->toArray());
$ua = unserialize($sa);
$b = SplFixedArray::fromArray($ua);
var_dump($b);
echo 'Sizeof $b = ' . $b->getSize(), PHP_EOL;
echo 'Count $b = ' . $b->count(), PHP_EOL;
-------------------------------------
Gives the expected results
Also I forgot in php >= 5.4.0RC3 (should I report this as separate bug?)
The actual result of var_dump($b) is:
$b = object(SplFixedArray)#2 (2) {
["0"]=>
int(1)
["1"]=>
int(2)
}
The keys are strings and not integers and this causes
-------------------------------------
$b = unserialize(serialize($a));
SplFixedArray::fromArray($b->toarray());
-------------------------------------
To throw an exception 'InvalidArgumentException' with message 'array must
contain only positive integer keys'
