iContact php jSON parsing issue

Question

I am playing around with iContact API and am running into an issue. After creating a contact using the api I am attempting to retrieve the most recent response so I can parse the contactId in order to send that contact a message or add them to a list.

// adds new client to iContact
var_dump($oiContact->addContact('[email protected]', null, null, 'Joe', 'Smith', null, '123 Somewhere Ln', 'Apt 12', 'Somewhere', 'NW', '12345', '123-456-7890', '123-456-7890', null));

// Gets last response (results are showing below
$obj = $oiContact->getLastResponse();

When print the $obj var this is what I get

{"contacts":[{"contactId":"1009090","prefix":"","firstName":"Joe","lastName":"Smith","suffix":"","street":"123 Somewhere Ln","street2":"Apt 12","city":"Somewhere","state":"NW","postalCode":"12345","phone":"123-456-7890","fax":"123-456-7890","business":"","email":"[email protected]","createDate":"2014-04-24 01:31:59","bounceCount":"","status":"normal"}]}

    //decode json object and echo it
    $data = json_decode($obj,TRUE);
    echo $data->contacts[0]->contactId;

Error Message: Notice: Trying to get property of non-object in …(path)... on line 24

I looked on other posts and attempted to duplicate some of the same solutions but nothing seemed to work. Thanks for any help in advanced.

If you are going to access in object method remove the TRUE from json_decode function parameter list. If you pass TRUE it returns an array.

$data = json_decode($obj);

Otherwise you have to access like this.

//decode json object and echo it
$data = json_decode($obj,TRUE);
echo $data['contacts'][0]['contactId'];
