note 87249 added to book.simplexml

Addition to QLeap's post: SimpleXML will return a reference to an object containing the node value and you can't use references in session variables as there is no feasible way to restore a reference to another variable. This won't work too: $val=$this->xml->node->attributes()->name; echo $array[$val]; // will cause a warning because of the wrong index type. You have to convert/cast to a String first: echo $array[(string)$val]; This will work as expected, because converting will call the __toString() method. Therefor echo works too: echo $val; // will display the name ---- Server IP: 212.124.37.9 Probable Submitter: 92.75.59.164 ---- Manual Page -- http://www.php.net/manual/en/book.simplexml.php Edit -- https://master.php.net/note/edit/87249 Del: integrated -- https://master.php.net/note/delete/87249/integrated Del: useless -- https://master.php.net/note/delete/87249/useless Del: bad code -- https://master.php.net/note/delete/87249/bad+code Del: spam -- https://master.php.net/note/delete/87249/spam Del: non-english -- https://master.php.net/note/delete/87249/non-english Del: in docs -- https://master.php.net/note/delete/87249/in+docs Del: other reasons-- https://master.php.net/note/delete/87249 Reject -- https://master.php.net/note/reject/87249 Search -- https://master.php.net/manage/user-notes.php
