GetAccountHierarchy (PHP) error array_key_exists()

[Mihai Iliescu]

Hello

I have a problem with the AdWords Api (PHP). When I run GetAccountHierarchy.php I get the following errors:

( ! ) Warning: array_key_exists(): The first argument should be either a string or an integer in C:\wamp\www\api\app\GetAccountHierarchy.php on line 84

Does anyone have any pointers on how to solve this?

Hi, 

Could you provide the complete GetAccountHierarchy.php code and the SOAP request and response logs? I see that the AdWords account 2975983167 is a client account. If you run this example against a client account, only that account will be returned in the response. Please use Reply privately to author when responding. 

Thanks,
