If you pass the JSON in your post to json_decode, it will fail. Valid JSON strings have quoted keys:

json_decode('{foo:"bar"}');         // this fails
json_decode('{"foo":"bar"}', true); // returns array("foo" => "bar")
json_decode('{"foo":"bar"}');       // returns an object, not an array.

How to loop this JSON object from php?
First of all, you have an error in your JSON data. Here is the fixed one: { "data": [ { "section": "Technology", "weighting": "0.15", "questions": [ { "id": "1", "weighting": "0.25", "score": "5" }, { "id": "2", "weighting": "0.25", "score": "5" } ] }, { "section": "Data", "weighting": "0.15", "questions": [ { "id": "1", "weighting": "0.25", "score": "5" }, { "id": "2", "weighting": "0.25", "score": "5" } ] } ] } I, then, created a file 'data.json' and 'test.php'. Here is 'test.php': '; } } It prints: 0.25 0.25 0.25 0.25 As you see, you made two mistakes: Your JSON data was corrupted and you were looping the whole array, but you have to loop array['data']. Hope it helps. P.S.: Get better in debugging PHP with print_r and echoes. Really helps. More on reddit.com

PHP: json_decode - Manual
You would expect that recoding and re-encoding will always yield the same JSON string, but take this example: $json = '{"0": "No", "1": "Yes"}'; $array = json_decode($json, true); // decode as associative hash print json_encode($array) . PHP_EOL; This will output a different JSON string than the original: ["No","Yes"] The object has turned into an array! Similarly, a array that doesn't have consecutive zero based numerical indexes, will be encoded to a JSON object instead of a list.
