Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php Use ArrayObject/ArrayIterator instead or as a wrapper around your arrays.

It seems that, used inside a recursive function, foreach doesn't use different array pointers for each iteration of the function, but uses the same at each time. This common pointer is reseted at each foreach() call. Reproduce code: --------------- function recurse($doRecurse = true) { static $array = array(1,2); foreach ($array as $value) { echo $value . PHP_EOL; if ($doRecurse) recurse(false); } } recurse(); Expected result: ---------------- 1 1 2 2 1 2 Actual result: -------------- 1 1 2 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=33713&edit=1
