Description: ------------ Regarding the DualIterator example, current version: http://cvs.php.net/viewvc.cgi/php- In its API documentation, the key() method claims to use the DualIterator::KEY_* constants, but the code makes use of CURRENT_* instead. Also, does the *_ARRAY option (which is used by default even for key()) does not make a lot of sense because arrays cannot be used as keys at least for foreach loops. (Might work with low-level iterator usage, but then again keys should probably be *real* keys in any case.) It would be nice to have these issues fixed (diff attached further down). Related feature request, totally not in scope for this bug report (sorry): it might be worthwhile to extend the flags to {CURRENT,KEY}_{LHS,RHS}_{KEY,VALUE} in order to make it possible to e.g. use the left hand side's current value as key for the iterator. At least, that's what I'm going to use my derived class for. Thanks for having a look (and for your work on PHP), regards, Jakob Reproduce code: --------------- $leftSideArray = array('lhs_key' => 'lhs_value'); $rightSideArray = array('rhs_key' => 'rhs_value'); $combined = new DualIterator( new ArrayIterator($leftSideArray), new ArrayIterator($rightSideArray), DualIterator::KEY_LHS | DualIterator::CURRENT_RHS ); foreach ($combined as $key => $value) { var_dump($key); var_dump($value); } Expected result: ---------------- string(7) "lhs_key" string(9) "rhs_value" Actual result: -------------- Warning: Illegal type returned from DualIterator::key() in /home/jakob/dev/www/drupal/6/transformations/sites/all/modules/tf_modu line 223 Call Stack: 0.0014 112544 1. {main}() /home/jakob/dev/www/drupal/6/transformations/sites/all/modules/tf_modu int(0) string(9) "rhs_value" -- Edit bug report at http://bugs.php.net/?id=47031&edit=1 -- Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=47031&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=47031&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=47031&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=47031&r=fixedcvs Fixed in CVS and need be documented: http://bugs.php.net/fix.php?id=47031&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=47031&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=47031&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=47031&r=needscript Try newer version: http://bugs.php.net/fix.php?id=47031&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=47031&r=support Expected behavior: http://bugs.php.net/fix.php?id=47031&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=47031&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=47031&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=47031&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=47031&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=47031&r=dst IIS Stability: http://bugs.php.net/fix.php?id=47031&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=47031&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=47031&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=47031&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=47031&r=mysqlcfg
