处理PHP SOAP中的空列表

Question

Initially if there was one item in the list it would return an object rather than an array of one object. I fixed that using:

https://eirikhoem.wordpress.com/2008/03/13/array-problems-with-soap-and-php-updated/

$x = new SoapClient($wsdl, array('features' => SOAP_SINGLE_ELEMENT_ARRAYS));

But I'm having problems when there is no items in the list.

The best I've come up with so far is:

$occulist = $result->GetWebOccurrencesResult->OccuList;
if (!empty((array)($occulist))) {
    foreach($occulist->TOccu as $occurrence) {
        echo $occurrence->Prog_Name . ' running from ' . $occurrence->StartDate . ' to ' . $occurrence->EndDate . '<br/>';
    }
}

Originally it was

foreach($result->GetWebOccurrencesResult->OccuList->TOccu as $occurrence) {

On my server with Windows and PHP 5.4.23 this:

if (!empty((array)($occulist))) {

gives the following error:

Parse error: syntax error, unexpected '(array)' (array) (T_ARRAY_CAST)

I fixed it using:

if (get_object_vars($occulist)) {

I think that is a more elegant alternative to the original...
