Description:
------------
I will report an issue reported in 15-09-2016 in this link https://bugs.php.net/bug.php?id=73089. 

The problem IS NOT RESOLVED.


I will be short: i have an WCF in a IIS Windows Server. This WCF host a web service with this function:

public Dictionary<string, string> TestRoutine(Dictionary<string, string> Data)

I calling this function with PHP with these rows:

$url = "http://testserver/test/test.svc?wsdl";
$soapClient = new SoapClient($url, array('cache_wsdl' => WSDL_CACHE_NONE) );
$argsSOAP = new StdClass();
$argsSOAP->Data = Array();
array_push($argsSOAP->Data, Array("Key"=>"A", "Value"=>"1"));
array_push($argsSOAP->Data, Array("Key"=>"B", "Value"=>"2"));
$resSOAP = $soapClient->TestRoutine($argsSOAP);
print_r($resSOAP);

In PHP 5.6.X these rows works! In PHP 7.0.11 NO! The "Data" parameter result empty

BUT

If I put the values into the dictionary with a direct assignment, not using "array_push":

$url = "http://testserver/test/test.svc?wsdl";
$soapClient = new SoapClient($url, array('cache_wsdl' => WSDL_CACHE_NONE) );
$argsSOAP = new StdClass();
$argsSOAP->Data = Array();
$argsSOAP->Data[0] = Array("Key"=>"A", "Value"=>"1");
$argsSOAP->Data[1] = Array("Key"=>"B", "Value"=>"2");
$resSOAP = $soapClient->TestRoutine($argsSOAP);
print_r($resSOAP);

IT WORKS!!! Why?
Can you check? My PHP application is all based with array_push. Please help
Thanks

Test script:
---------------
$url = "http://testserver/test/test.svc?wsdl";
$soapClient = new SoapClient($url, array('cache_wsdl' => WSDL_CACHE_NONE) );
$argsSOAP = new StdClass();
$argsSOAP->Data = Array();
array_push($argsSOAP->Data, Array("Key"=>"A", "Value"=>"1"));
array_push($argsSOAP->Data, Array("Key"=>"B", "Value"=>"2"));
$resSOAP = $soapClient->TestRoutine($argsSOAP);
print_r($resSOAP);

Expected result:
----------------
The web service receive a dictionary with two element

Actual result:
--------------
The web service receive a null element!
