将数据从simpleXML重新调整为数组

Question

I'm having trouble accessing variable from an object. The object is coming from an API feed and a var_dump looks like this:

object(stdClass)#2 (1) {
  ["GetBookingsResult"]=>
  string(189227) "<Bookings>
  <Data>
    <BookingDate>2012-01-06T00:00:00-06:00</BookingDate>

    <ChangedBy>J Smith</ChangedBy>
  </Data>
</Bookings>"
}

I want to be able to reorder the info that comes back into an array so that I can group the events by date and then order them by EventName. Below is my code:

$xml = simplexml_load_string($result->GetBookingsResult);

$list='';
    foreach($xml as $event){
        $st_date = lvmDateFormat($event->TimeBookingStart,'name');//function reformats date
        $en_date = lvmDateFormat($event->TimeBookingEnd,'name');
        $name =  lvmDateFormat($event->TimeBookingStart,'cal');
        $ename = $event->EventName;
$events[lvmDateFormat($event->TimeBookingStart,'name')][$st_date] = array(
            'EventName' => $ename
            ,'Date' => $name
            ,'TimeEventStart' => $st_date
            ,'TimeEventEnd' => $en_date
        );
    }

If I echo out $event->EventName; it looks fine, but when I try to add it to an array it comes back like this:

 [EventName] => SimpleXMLElement Object
                (
                    [0] => UMW Training Event
                )

What am I doing wrong here?

Answer 1

When you echo an object, it is converted to a string. So it will appear (because SimpleXMLElement defines a __toString() method internally) like you want it to - but the type of the $event variable is still an object of type SimpleXMLElement.

You can easily store it as a string in the array, if you cast it to a string. Try changing this line:

$ename = $event->EventName;

...to this:

$ename = (string) $event->EventName;
