如何在PHP中使用NuSOAP处理超时？

Question

I am using NuSOAP to consume a webservice for a payment gateway, however, the documentation for this gateway requires that:

• If the doPayment() method takes more than 300 seconds, it should immediately execute the getStatus() method at least 3 times in order to try to get a successful response.

The thing is, I don't know how to handle that timeout with PHP and NuSOAP. Does NuSOAP returns any specific response when there's a timeout? how do I now it actually timed out?

Here is a piece of code for the NuSOAP call:

$client = new nusoap_client( 'http://webserviceurl?wsdl...' , 'wsdl');

$err = $client->getError();
if ($err)
    die('Constructor error: ' . $err);

$proxy = $client->getProxy();

$payTrans = $proxy->doPayment(array('someparams' => 'somevalues'));

// if doPayment() timed out, then run the getStatus() method

Any input would be greatly appreciated. Thank you!

I'm answering it myself for future reference. First of all you need to extend the timeout value for the nusoap_client class. Then just start a timer before the method you want to test and compare it to the time it took to end:

// Extending the timeout value to 300 seconds
$client = new nusoap_client( 'http://webserviceurl?wsdl...' , 'wsdl' , false, false, false, false, 0, 300)

$err = $client->getError();
if ($err)
    die('Constructor error: ' . $err);

$proxy = $client->getProxy();

$start = time(); // starting the timer
$payTrans = $proxy->doPayment(array('someparams' => 'somevalues'));
$timing = time() - $start; // calculating the transaction time

if($timing > 90 && $timing < 310)
    // It timed out: send an email, run another method, etc
