#46958 [NEW]: iterator_to_array() does not return every inner iterator of an AppendIterator

From: pestilence669@php.net Operating system: Mac OS X 10.5.6 PPC PHP version: 5.2.8 PHP Bug Type: SPL related Bug description: iterator_to_array() does not return every inner iterator of an AppendIterator Description: ------------ The SPL iterator_to_array() function does not appear to include every inner iterator contained within an AppendIterator. It seems that it only processes the very last iterator that was appended. I'd expect that array conversion would parallel the traversal of foreach, but it does not. To maintain consistency within SPL itself, I'd suggest that this be corrected. If the behavior can be confirmed, I'm willing to supply the patch & regression tests. I'd like more karma. I've also verified this w/ version 5.2.6 on the same platform and version 5.2.3-1ubuntu6 on x86 32-bit Linux. Reproduce code: --------------- <?php $r = new AppendIterator(); $r->append(new ArrayIterator(array(1,2))); $r->append(new ArrayIterator(array(3,4))); $r->append(new ArrayIterator(array(5,6))); // only sees 5 and 6: print_r(iterator_to_array($r)); // this works as expected: foreach ($r as $i) echo $i; ?> Expected result: ---------------- Array ( [0] => 1 [1] => 2 [2] => 3 [3] => 4 [4] => 5 [5] => 6 ) Actual result: -------------- Array ( [0] => 5 [1] => 6 ) -- Edit bug report at http://bugs.php.net/?id=46958&edit=1 -- Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=46958&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=46958&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=46958&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=46958&r=fixedcvs Fixed in CVS and need be documented: http://bugs.php.net/fix.php?id=46958&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=46958&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=46958&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=46958&r=needscript Try newer version: http://bugs.php.net/fix.php?id=46958&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=46958&r=support Expected behavior: http://bugs.php.net/fix.php?id=46958&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=46958&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=46958&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=46958&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=46958&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=46958&r=dst IIS Stability: http://bugs.php.net/fix.php?id=46958&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=46958&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=46958&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=46958&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=46958&r=mysqlcfg
