note 71728 added to ref.simplexml

One way to work around the issue that Arnaud presented on 19-Oct-2006 is to check for the existence of the node before doing a 'foreach' on it. <?php $xml = simplexml_load_string('<root></root>'); if( $xml->b ) // Or maybe 'isset' or 'array_key_exists' { foreach($xml->b as $dummy); } echo $xml->asXML(); ?> Gives the expected result: <?xml version="1.0"?> <root/> You can see the same behavior using an array, although you'll get a warning: <?php $p['a'] = '1'; foreach( $p['b'] as $node ); print_r( $p ); ?> Result: Warning: Invalid argument supplied for foreach() Array ( [a] => 1 [b] => ) ---- Server IP: 64.71.164.2 Probable Submitter: 216.16.37.11 ---- Manual Page -- http://www.php.net/manual/en/ref.simplexml.php Edit -- https://master.php.net/note/edit/71728 Del: integrated -- https://master.php.net/note/delete/71728/integrated Del: useless -- https://master.php.net/note/delete/71728/useless Del: bad code -- https://master.php.net/note/delete/71728/bad+code Del: spam -- https://master.php.net/note/delete/71728/spam Del: non-english -- https://master.php.net/note/delete/71728/non-english Del: in docs -- https://master.php.net/note/delete/71728/in+docs Del: other reasons-- https://master.php.net/note/delete/71728 Reject -- https://master.php.net/note/reject/71728 Search -- https://master.php.net/manage/user-notes.php
