Reproduce code: --------------- <?php $xmlstring=" <xml> <node>0</node> </xml>"; $xmlelement=new SimpleXMLElement($xmlstring); echo "(int)element: "; var_dump((int)$xmlelement->node); echo "--\n"; echo "(bool)element: "; var_dump((bool)$xmlelement->node); echo "--\n"; echo "(bool)(string)element: "; var_dump((bool)(string)$xmlelement->node); Expected result: ---------------- (int)element: int(0) -- (bool)element: bool(false) -- (bool)(string)element: bool(false) Actual result: -------------- (int)element: int(0) -- (bool)element: bool(true) -- (bool)(string)element: bool(false) ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=46122&edit=1
