What are the potential benefits and drawbacks of using multidimensional arrays in PHP for complex data structures?

Using multidimensional arrays in PHP can be beneficial for organizing complex data structures in a hierarchical way, making it easier to access and manipulate nested data. However, it can also lead to increased complexity and potential confusion when working with deeply nested arrays. It's essential to carefully plan and document the structure of multidimensional arrays to avoid confusion and ensure efficient data retrieval. 

// Example of using a multidimensional array to store complex data
$studentData = array(
    'John Doe' => array(
        'age' => 20,
        'grades' => array(85, 90, 78)
    ),
    'Jane Smith' => array(
        'age' => 22,
        'grades' => array(92, 88, 95)
    )
);

// Accessing data from the multidimensional array
echo $studentData['John Doe']['age']; // Output: 20
echo $studentData['Jane Smith']['grades'][0]; // Output: 92
