ID: 39164 User updated by: php at bouchery dot com Reported By: php at bouchery dot com -Status: Bogus +Status: Open Bug Type: SimpleXML related Operating System: Windows XP PHP Version: 5.1.6 New Comment: If there is no nodes, I browse like an array, no data is display, but a node was created. If I do it twice, it display something ! Browsing tree MUST NOT create node. Look at this : <?php $xml = simplexml_load_string('<root></root>'); foreach( $xml->a as $a ) echo "a = $a\n"; foreach( $xml->a as $a ) echo "a = $a\n"; ?> A the second time, it display : "a =" Sorry to insist, but it is not "normal" (and I can't see that in the documentation !!).

Even if it's written, it's a strange behaviour and shoud be a change request. Reading data should not modify it. ------------------------------------------------------------------------ [2006-10-16 15:57:41] helly@php.net Thank you for taking the time to write to us, but this is not a bug.
