When you use the Facebook PHP SDK, it automatically decodes the returned json object into a PHP array. If you need a json object from it, you'll have to use json_encode on it after you finish processing it.
You've got some major problems with your php code. Just to get started:
Your foreach loop ends as soon as it starts with the } on the next line.
Where do you define the variables $values and $album?
You are referencing $values2 outside of your foreach loop.
You are appending to an uninitialized variable on your line $outputStr .= "[";.
If you pass json_encode() a proper php array of data, it will make a complete json object. You shouldn't need to be appending brackets of any kind.
