用php提取每个级别的数据

Question

The following is the JSon data.

{
        "statusType": "OK",
        "entity": [
            {
            "category": "category1","difficultyLevel": "Easy",
            "quizAnswerChoices": [{"choiceText": "Yes", "choiceTextHash": "c3f1130841b507a4d1e0f45971d990c6ecd25406"}, {"choiceText": "Yes", "choiceTextHash": "c3f1130841b507a4d1e0f45971d990c6ecd25406"}]
            }
        ],
        "entityType": "java.util.ArrayList",
        "status": 200,
        "metadata": {}
    }

I need to parse - entity - quizAnswerChoices (count the item)

How to retrieve each choiceText etc

Answer 1

If you do a json_decode like

$data = json_decode(json_data);

Then $data will be a traversable array

$data['entity']['quizAnswerChoices'] etc
