Having trouble processing XML with PHP SimpleXML - simplexml

Question

http://pastie.org/1701923 Here is the XML being returned from an API I am querying for zip codes.
I want to pull the data out of each entry and either loop it directly or put it into an array that I can loop. I can't seem to get it right. Here is the latest code I was using:
$xml = new SimpleXMLElement($results);
foreach($xml->zipcoderadius->zipcodes as $loc) {
$codes[] = (string)$loc['zipcode'];
}
print_r($codes);
die();
($results is the returned XML from CURL)
What is being output is Array ( [0] => [1] => [2] => [3] => [4] => )

Answer 1

I think this was,n be a string (zipcode). Try without string

Answer 2

I am not sure you're addressing the zip code correctly. For me the following works, assuming you stored your cURL result in $xmlStr previously.
$push = array();
$foo = simplexml_load_string($xmlStr);
foreach($foo->zipcoderadius->zipcodes->id as $bar) {
array_push($push, (string)$bar);
}
print_r($push);
Leading to the following output:
Array
(
[0] => 75969
[1] => 75970
[2] => 75971
)
By the way: the SimpleXML object looks like this:
object(SimpleXMLElement)#1 (1) {
["zipcoderadius"]=>
object(SimpleXMLElement)#4 (1) {
["zipcodes"]=>
object(SimpleXMLElement)#3 (32) {
["id"]=>
array(3) {
[0]=>
string(5) "75969"
[1]=>
string(5) "75970"
[2]=>
string(5) "75971"
}
["zipcode"]=>
array(3) {
[0]=>
string(5) "94945"
[1]=>
string(5) "94945"
[2]=>
string(5) "94945"
}
