note 100162 added to class.simplexmlelement

You should cast elements to a float (or even string) if you plan on using them in addition, multiplication, etc. If you don't then PHP will incorrectly treat the node values as an integer. <?php $obj = new SimpleXMLElement('<root> <a>1.9</a> <b>1.9</b> </root>'); var_dump($obj->a + $obj->b); var_dump((float)$obj->a + (float)$obj->b); var_dump((string)$obj->a + (string)$obj->b); ?> The first line gives: int(2) The second and third give the expected result: float(3.8) ---- Server IP: 117.55.229.1 Probable Submitter: 203.201.149.10 ---- Manual Page -- http://www.php.net/manual/en/class.simplexmlelement.php Edit -- https://master.php.net/note/edit/100162 Del: integrated -- https://master.php.net/note/delete/100162/integrated Del: useless -- https://master.php.net/note/delete/100162/useless Del: bad code -- https://master.php.net/note/delete/100162/bad+code Del: spam -- https://master.php.net/note/delete/100162/spam Del: non-english -- https://master.php.net/note/delete/100162/non-english Del: in docs -- https://master.php.net/note/delete/100162/in+docs Del: other reasons-- https://master.php.net/note/delete/100162 Reject -- https://master.php.net/note/reject/100162 Search -- https://master.php.net/manage/user-notes.php
