We discovered this bug when passing data returned by the official AWS DynamoDB client to SoapClient, but reproduce it below with a few lines of PHP. https://github.com/aws/aws-sdk-php/blob/3.17.5/src/DynamoDb/Marshaler.php#L285 Test script: --------------- <?php $client = new SoapClient(null, ['uri' => '', 'location' => '']); $data = [[null]]; foreach ($data as &$value) { foreach ($value as &$_value) { $_value = 'foo'; } } $client->__soapCall('call', $data); Expected result: ---------------- PHP Fatal error: Uncaught SoapFault exception: [HTTP] Unable to parse URL (Because SoapClient attempts to retrieve the WSDL from the invalid URL provided in the test code. This error is seen in PHP5.) Actual result: -------------- Fatal error: Uncaught SoapFault exception: [Client] SOAP-ERROR: Encoding: Cannot find encoding ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=71986&edit=1
