PHP SoapClient - Multiple attributes with the same key

Question

I\'m using SoapClient, trying to produce something for this specification:

Answer 1

The ContactProfileAttribute element is one level too deep. Try:

$params = array(
    'WSContact' => array(
        'EmailAddress' => $email,
        'ListID' => $listId,
        'ContactProfileAttribute' => $attrs
    ),
    'ProfileUpdateType' => 'Overwrite',
    'ExternalEventIDs' => "",
    'OverrideUnsubscribe' => TRUE,
);
