Forcing a SimpleXML Object to a string, regardless of context
Typecast the SimpleXMLObject to a string:
$foo = array( (string) $xml->channel->item->title );The above code internally calls __toString() on the SimpleXMLObject. This method is not publicly available, as it interferes with the mapping scheme of the SimpleXMLObject, but it can still be invoked in the above manner.
There is native SimpleXML method SimpleXMLElement::asXMLDepending on parameter it writes SimpleXMLElement to xml 1.0 file or just to a string:
$xml = new SimpleXMLElement($string);$validfilename = '/temp/mylist.xml';$xml->asXML($validfilename); // to a fileecho $xml->asXML(); // to a string
