What are common challenges faced when working with multi-dimensional JSON data in PHP?

One common challenge when working with multi-dimensional JSON data in PHP is accessing nested values within the data structure. To solve this, you can use a combination of array access and loops to navigate through the nested structure and retrieve the desired values.

$jsonData = '{
    "name": "John",
    "age": 30,
    "address": {
        "street": "123 Main St",
        "city": "New York"
    }
}';

$data = json_decode($jsonData, true);

// Accessing nested values
echo $data['name']; // Output: John
echo $data['address']['city']; // Output: New York
