ID: 60560 Comment by: php at maisqi dot com Reported by: digital1kk at interia dot pl Summary: SplFixedArray un-/serialize, getSize(), count() return 0, keys are strings Status: Closed Type: Bug Package: SPL related PHP Version: Irrelevant Assigned To: aharvey Block user comment: N Private report: N New Comment: 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? Previous Comments: ------------------------------------------------------------------------ [2012-06-18 15:57:56] php at maisqi dot com 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. </p> <hr /> <pre> <?php $fn = 'serial.txt'; $x = new SplFixedArray (4); $x [0] = 123; $x [1] = 456; $x [2] = 789; $x [3] = 'abc'; echo "<strong>SplFixedArray to serialize</strong>:\n"; print_r ($x); echo "\ncount: <strong>", $x->getSize (), "</strong>"; echo "\n<strong>First element</strong>: "; try { $o = $x [0]; } catch (Exception $e) { $o = 'Error!'; } echo "<strong>$o</strong>\n"; echo "\n\nSerializing to file \"$fn\"...\n"; file_put_contents ($fn, serialize ($x)); echo "\n\nUnserializing from file \"$fn\"...\n"; $x = unserialize (file_get_contents ($fn)); echo "\n\n<strong>Unserialized SplFixedArray</strong>:\n"; print_r ($x); echo "\ncount: <strong>", $x->getSize (), "</strong>"; echo "\n<strong>First element</strong>: "; try { $o = $x [0]; } catch (Exception $e) { $o = 'Error!'; } echo "<strong>$o</strong>\n"; if ($buf = @file_get_contents ('error_log')) { echo "\n\n<strong>Last errors</strong>:\n", $buf; } ?> </pre> </body> </html> ------------------------------------------------------------------------ [2012-02-21 10:34:50] ahar...@php.net This bug has been fixed in SVN.

Fixed on trunk. ------------------------------------------------------------------------ [2012-02-21 10:34:39] ahar...@php.net 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). ------------------------------------------------------------------------ [2011-12-19 13:49:25] digital1kk at interia dot pl 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' ------------------------------------------------------------------------ [2011-12-19 10:31:53] digital1kk at interia dot pl Description: ------------ If SplFixedArray object is created via unserialize() of serialized instance then the getSize() and count() methods return 0 instead of expected actual size.
