Get value from SimpleXMLElement Object

I have something like this:

$url = "http://ws.geonames.org/findNearbyPostalCodes?country=pl&placename=";
$url .= rawurlencode($city[$i]);

$xml = simplexml_load_file($url);
echo $url."\n";
$cityCode[] = array(
    'city' => $city[$i], 
    'lat' => $xml->code[0]->lat, 
    'lng' => $xml->code[0]->lng
);

It's supposed to download XML from geonames. If I do print_r($xml) I get : 

SimpleXMLElement Object
(
    [code] => Array
        (
            [0] => SimpleXMLElement Object
                (
                    [postalcode] => 01-935
                    [name] => Warszawa
                    [countryCode] => PL
                    [lat] => 52.25
                    [lng] => 21.0
                    [adminCode1] => SimpleXMLElement Object
                        (
                        )

                    [adminName1] => Mazowieckie
                    [adminCode2] => SimpleXMLElement Object
                        (
                        )

                    [adminName2] => Warszawa
                    [adminCode3] => SimpleXMLElement Object
                        (
                        )

                    [adminName3] => SimpleXMLElement Object
                        (
                        )

                    [distance] => 0.0
                )

I do as you can see $xml->code[0]->lat and it returns an object. How can i get the value?

This question is quite old - I appreciate that, but I also discovered (in PHP 8.2) that you can use trim() on a SimpleXMLElement Object and whilst the input isn't technically a string, it will convert it! Not sure if that is a glitch with PHP as clearly its an object not a string but does work as of 2024.

Quick Solution if you in hurry.

convert a Xml-Object to an array (or object),

function loadXml2Array($file,$array=true){
   $xml = simplexml_load_file($file);   
 
   $json_string = json_encode($xml);    
   return json_decode($json_string, $array);
}

you can use the '{}' to access you property, and then you can do as you wish. Save it or display the content.

    $varName = $xml->{'key'};

From your example her's the code

        $filePath = __DIR__ . 'Your path ';
        $fileName = 'YourFilename.xml';

        if (file_exists($filePath . $fileName)) {
            $xml = simplexml_load_file($filePath . $fileName);
            $mainNode = $xml->{'code'};

            $cityArray = array();

            foreach ($mainNode as $key => $data)        {
               $cityArray[..] = $mainNode[$key]['cityCode'];
               ....

            }     

        }

$codeZero = null;
foreach ($xml->code->children() as $child) {
   $codeZero = $child;
}

$lat = null;
foreach ($codeZero->children() as $child) {
   if (isset($child->lat)) {
      $lat = $child->lat;
   }
}

you can convert array with this function

function xml2array($xml){
$arr = array();

foreach ($xml->children() as $r)
{
    $t = array();
    if(count($r->children()) == 0)
    {
        $arr[$r->getName()] = strval($r);
    }
    else
    {
        $arr[$r->getName()][] = xml2array($r);
    }
}
return $arr;
}

try current($xml->code[0]->lat)

it returns element under current pointer of array, which is 0, so you will get value

This is the function that has always helped me convert the xml related values to array

function _xml2array ( $xmlObject, $out = array () ){
    foreach ( (array) $xmlObject as $index => $node )
        $out[$index] = ( is_object ( $node ) ) ? _xml2array ( $node ) : $node;

    return $out;
}

foreach($xml->code as $vals )
{ 
    unset($geonames);
    $vals=(array)$vals;
    foreach($vals as $key => $value)
      {
        $value=(array)$value;
        $geonames[$key]=$value[0];
      }
}
print_r($geonames);

header("Content-Type: text/html; charset=utf8");
$url  = simplexml_load_file("http://URI.com");

 foreach ($url->PRODUCT as $product) {  
    foreach($urun->attributes() as $k => $v) {
        echo $k." : ".$v.' <br />';
    }
    echo '<hr/>';

if you don't know the value of XML Element, you can use

$value = (string) $xml->code[0]->lat;

if (ctype_digit($value)) {
    // the value is probably an integer because consists only of digits
}

It works when you need to determine if value is a number, because (string) will always return string and is_int($value) returns false

If you know that the value of the XML element is a float number (latitude, longitude, distance), you can use (float)

$value = (float) $xml->code[0]->lat;

Also, (int) for integer number:

$value = (int) $xml->code[0]->distance;

You can also use the magic method __toString()

$xml->code[0]->lat->__toString()

You have to cast simpleXML Object to a string.

$value = (string) $xml->code[0]->lat;
