create php array using simpleXMLobject - php

Question

I'm trying to get this array ($resdata) with object(SimpleXMLElement) into a php array:
$resdata =
array(59) {
[0]=> ...
[10]=> object(SimpleXMLElement)#294 (28) {
["reservation_id"]=> string(7) "8210614"
["event_id"]=> string(6) "279215"
["space_reservation"]=> array(2) {
[0]=> object(SimpleXMLElement)#344 (9) {
["space_id"]=> string(4) "3760"
["space_name"]=> string(9) "205"
["formal_name"]=> string(33) "Center" }
[1]=> object(SimpleXMLElement)#350 (9) {
["space_id"]=> string(4) "3769"
["space_name"]=> string(9) "207"
["formal_name"]=> string(32) "Right" } } }
}
I've tried:
$res = (array)$resdata;
$reservation = $res['reservation'];
$result = array();
foreach ($reservation as $key => $value){
$res = array($value);
$spid = $res[0]->space_reservation->space_id;
echo $value->event_id."<br />";
echo $spid."<br />";
}
This only outputs the first space_id and I need to get all the space_ids within "space_reservation" array. Not all records will have multiple space_ids. Any help pointing me in the right direction is appreciated. Not sure if I should use xpath but I need to re-write my foreach statement regardless.
I was hoping to be able to literally convert all references to "object(SimpleXMLElement)#_ (#)" to "array(#)"
[10]=> array (28) {
["reservation_id"]=> string(7) "8210614"
["event_id"]=> string(6) "279215"
["space_reservation"]=> array(2) {
[0]=> array (9) {
["space_id"]=> string(4) "3760"
["space_name"]=> string(9) "205"
["formal_name"]=> string(33) "Center" }
[1]=> array (9) {
["space_id"]=> string(4) "3769"
["space_name"]=> string(9) "207"
["formal_name"]=> string(32) "Right" } } }
}
the function in my cakephp 1.3 controller is this:
$xml = simplexml_load_string($string);
$this->data['events']= $xml->children();
$resdata = $this->data['events'];
$this->set('resdata',$resdata);

Answer 1

I think this should do what you are looking for:
foreach ($resdata as $res) {
echo $res->event_id . '<br />';
foreach ($res->space_reservation as $reservation) {
echo $reservation->space_id . '<br />';
}
}

Googled it and found a general solution for any SimpleXMLElement to array conversion:
function xml2array($xml) {
$arr = array();
foreach ($xml as $element) {
$tag = $element->getName();
$e = get_object_vars($element);
if (!empty($e)) {
$arr[$tag] = $element instanceof SimpleXMLElement ? xml2array($element) : $e;
}
else {
$arr[$tag] = trim($element);
}
}
return $arr;
}
