• Forcing a SimpleXML Object to a string, regardless of context 10 answers

I have an XML File for an API. The API responses everytime "Errormesage: Expected argument of type "string", "array" given".

$SimpleXML_loaded_File = simplexml_load_file("http://graphics.edc-internet.nl/b2b_feed.php?key=tc62te28wt3e2t73ctr9c1cw42601337&sort=xml&type=xml&lang=de");

foreach ($SimpleXML_loaded_File->product as $product) {

  /*$client->post('articles', array(
      'name' => $product->titel,
      'taxId' => 1,
      'supplier' => $product->merk,
      'mainDetail' => array(
          'number' => $product->artikelnummer
      )
  ));*/

echo "<pre>";
var_dump($product->artikelnummer);
echo "</pre>";

}

If i var_dump the Output i dont get a string i`m getting the object

object(SimpleXMLElement)#6 (1) {
  [0]=>
  string(7) "0633178"
}

How do i get only the string ?

SimpleXML is simple for a reason. When echoing an element, it automatically converts the object to a string. You can also explicitly cast it to one:

echo (string)$product->artikelnummer;
