Calling methods in returned SOAP objects

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



I'm successfully calling SOAP functions via a WSDL interface using PHP5, but sometimes the functions return things that are complex objects with methods as well as attributes. For example, the interface I'm using has a query function which returns an array, but it also has a function called IsDone() which can be called to find out if this is the last page of results (it returns records in batches).

It goes like this:

<?php
require_once 'MyClient.class.php';

$mc = new MyClient();
$mc->dologin('id', 'pass');
try {
$res = $mc->query(array('queryString' => 'select Field from Table'));
    $alldone = $res->isDone();
} catch (SoapFault $f) {
    print 'Caught Exception: '. $f->faultstring. "\n";
    var_dump($mc);
}
?>

You can see that $res is the result returned from the query, and it is presented as a stdClass object with results stored in an array property. However, when I try to call $res->IsDone(), it fails to work:

PHP Fatal error:  Call to undefined method stdClass::isDone()

I have some example code in Java for the same WSDL that makes it look very simple:

...
queryResult = binding.query("select Field from Table");
if (queryResult.isDone()) {
...

How on earth do I do that in PHP? I don't think that creating PHP classes and using classmap will help (it just moves the problem), at least partly because this is a dynamic WSDL that is subject to change.
