Got confused. ------------------------------------------------------------------------ [2011-11-27 11:32:43] snapwilliam at gmail dot com Where can I find the explanation as to why this is not a bug? ------------------------------------------------------------------------ [2009-08-27 11:41:12] colder@php.net Sorry, but your problem does not imply a bug in PHP itself. For a list of more appropriate places to ask for help using PHP, please visit http://www.php.net/support.php as this bug system is not the appropriate forum for asking support questions. Due to the volume of reports we can not explain in detail here why your report is not a bug. The support channels will be able to provide an explanation for you. Thank you for your interest in PHP. foreach by ref will not delete the reference after foreach is finished, meaning $b is still a ref to the last element after the first foreach, which you then overwrite with the values of the second array. ------------------------------------------------------------------------ [2009-08-27 11:38:36] ingo dot aengenheister at gmx dot de Description: ------------ is it a bug or a feature ?
