note 80968 added to ref.simplexml

It doesn't seem to be documented anywhere, but you can refer to an element "value" for the purpose of changing it like so: <?php $xml = simplexml_load_string('<root><number>1</number></root>'); echo $xml->asXml(). "\n\n"; $xml->number->{0} = $xml->number->{0} + 1; echo $xml->asXml(); ?> echos: <?xml version="1.0"?> <root><number>1</number></root> <?xml version="1.0"?> <root><number>2</number></root> However, this only works with a direct assignment, not with any of the other operators: <?php $xml = simplexml_load_string('<root><number>1</number></root>'); echo $xml->asXml(). "\n\n"; $xml->number->{0} += 1; // Or: $xml->number->{0}++; echo $xml->asXml(); ?> Both of the above cases would result in: <?xml version="1.0"?> <root><number>1</number></root> <?xml version="1.0"?> <root><number>1<0/></number></root> ---- Server IP: 194.145.210.3 Probable Submitter: 64.236.80.62 ---- Manual Page -- http://www.php.net/manual/en/ref.simplexml.php Edit -- https://master.php.net/note/edit/80968 Del: integrated -- https://master.php.net/note/delete/80968/integrated Del: useless -- https://master.php.net/note/delete/80968/useless Del: bad code -- https://master.php.net/note/delete/80968/bad+code Del: spam -- https://master.php.net/note/delete/80968/spam Del: non-english -- https://master.php.net/note/delete/80968/non-english Del: in docs -- https://master.php.net/note/delete/80968/in+docs Del: other reasons-- https://master.php.net/note/delete/80968 Reject -- https://master.php.net/note/reject/80968 Search -- https://master.php.net/manage/user-notes.php
