_getFunctions can return null, not only array. This happens if the WSDL has not been parsed yet. This may be helpful to someone debugging, just like I was a few minutes ago when writing an extension to SoapClient.
(PHP 5 >= 5.0.1, PHP 7)
SoapClient::__getFunctions — Returns list of available SOAP functions
Returns an array of functions described in the WSDL for the Web service.
Note:
此函数仅在 WSDL 模式下生效。
此函数没有参数。
The array of SOAP function prototypes, detailing the return type, the function name and type-hinted parameters.
Example #1 SoapClient::__getFunctions() example
<?php
$client = new SoapClient('http://soap.amazon.com/schemas3/AmazonWebServices.wsdl');
var_dump($client->__getFunctions());
?>
以上例程会输出：
array(26) {
[0]=>
string(70) "ProductInfo KeywordSearchRequest(KeywordRequest $KeywordSearchRequest)"
[1]=>
string(79) "ProductInfo TextStreamSearchRequest(TextStreamRequest $TextStreamSearchRequest)"
[2]=>
string(64) "ProductInfo PowerSearchRequest(PowerRequest $PowerSearchRequest)"
...
[23]=>
string(107) "ShoppingCart RemoveShoppingCartItemsRequest(RemoveShoppingCartItemsRequest $RemoveShoppingCartItemsRequest)"
[24]=>
string(107) "ShoppingCart ModifyShoppingCartItemsRequest(ModifyShoppingCartItemsRequest $ModifyShoppingCartItemsRequest)"
[25]=>
string(118) "GetTransactionDetailsResponse GetTransactionDetailsRequest(GetTransactionDetailsRequest $GetTransactionDetailsRequest)"
}

The following code works for me while it appears soap.amazon.com has been deprecated and taken out of service. http://webservices.amazon.com has replaced Amazon's SOAP.
<?php
$client = new SoapClient('http://webservices.amazon.com/AWSECommerceService/AWSECommerceService.wsdl');
var_dump($client->__getFunctions());
?>
This function did not work if schema is not in wsdl file.
