PHP return object from SOAP

Question

How to store SOAP returned value in PHP?

My PHP code using SOAP.

    <?php
        $client = new SoapClient("http://rscnagahrd/OracleWS/Oracle.asmx?WSDL");
        $result = $client->getFoods();
        echo $result;
    ?>

When I try to run the application I get the error:

Catchable fatal error: Object of class stdClass could not be converted to string in C:\apache\htdocs\food.php on line 4

I am doing this so that I could later parse the xml code:

$dom = new DomDocument;
$dom->preserveWhiteSpace = FALSE;
$dom->loadXML($result);
$params = $dom->getElementsByTagName('FOOD_ID');
    foreach ($params as $param) {
    echo $param -> nodeValue, PHP_EOL;
}

The Soapclient object already has parsed the XML to a response structure (var_dump($result) and see). If you want to store it as a string, you'd have make it a string again somehow (serialize() if only PHP code needs to read it, json_encode() if you want to make it more language-agnostic are the usual suspects).

If you need to store the raw xml response, add array('trace' => true); as the 2nd parameter in SoapClient's constructor, and call $client->__getLastRequest();.

But, if you just want the answer used then & there the $result response is already parsed for you.

Ah, what question did you mean to ask?

Inside $result is an xml name food_name, food_description, etc, how can i extract them and place them into a php variable, debugging in visual studio returns something like:

<Table diffgr:id="Table1" msdata:rowOrder="0"> <FOOD_ID> 1 </FOOD_ID> <FOOD_NAME> Burger </FOOD_NAME> <FOOD_DESC> 100% Beef Patty </FOOD_DESC> <FOOD_PRICE> 25 </FOOD_PRICE> </Table> <Table diffgr:id="Table2" msdata:rowOrder="1"> <FOOD_ID> 2 </FOOD_ID> <FOOD_NAME> Coke </FOOD_NAME> <FOOD_DESC> Drinks </FOOD_DESC> <FOOD_PRICE> 10 </FOOD_PRICE> </Table>

It depends on whether that is sent as actual xml in the soap response (so you'd acces it something like foreach($result->Table as $food) echo $food->FOOD_ID.':'.$food->FOOD_NAME, or as encoded xml (i.e: it will be as a string in some location in the struct, and we need to build in object out of it). If you put the results of var_dump($result); up somewhere on pastebin.com or something like that, I could tell you more.

var_dum($result). I have also tried foreach($result->Table as $food) echo $food->FOOD_ID.':'.$food->FOOD_NAME but i am getting an error foreach
