Description:
------------
The server.php script shown below fails with a 'PHP Fatal error:  Maximum execution time of 30 seconds exceeded in /var/www/html/server.php on line 9' when executed with the supplied soaptest.wsdl file.

However, if you edit soaptest.wsdl and replace 'soapenc:array' with 'soapenc:Array' (i.e., change the lower case 'a' to an upper case 'A'), then the script executes correctly.

The first case should at least return an error, rather than seemingly causing the server to enter an infinite loop.

Reproduce code:
---------------
server.php:

<?php
class SOAPTest {
        public function GetArray() {
                return array('one', 'two', 'three');
        }
}
$server = new SoapServer(dirname(__FILE__) . '/soaptest.wsdl');
$server->setClass('SOAPTest');
$server->handle();
?>

client.php:

<?php
$client = new SoapClient(dirname(__FILE__) . '/soaptest.wsdl', array('exceptions' => false));
header('Content-Type: text/plain');
$ret = $client->GetArray();
if (is_soap_fault($ret))
        echo "SOAP Fault: " . $ret->faultstring;
else
        var_dump($ret);
?>

Expected result:
----------------
array(3) {
  [0]=>
  string(3) "one"
  [1]=>
  string(3) "two"
  [2]=>
  string(5) "three"
}

Actual result:
--------------
SOAP Fault: Maximum execution time of 30 seconds exceeded
