In PHP, what are some best practices for structuring multidimensional arrays to store related data efficiently?

When structuring multidimensional arrays to store related data efficiently in PHP, it is best practice to use associative arrays with meaningful keys to easily access and manipulate the data. Additionally, organizing the data in a hierarchical manner can help maintain clarity and organization within the array. Using nested arrays or arrays of objects can also be beneficial for complex data structures. 

// Example of structuring a multidimensional array efficiently

$data = array(
    'users' => array(
        array(
            'name' => 'John Doe',
            'age' => 30,
            'email' => 'john.doe@example.com'
        ),
        array(
            'name' => 'Jane Smith',
            'age' => 25,
            'email' => 'jane.smith@example.com'
        )
    ),
    'products' => array(
        array(
            'name' => 'Product A',
            'price' => 50.00,
            'quantity' => 10
        ),
        array(
            'name' => 'Product B',
            'price' => 75.00,
            'quantity' => 5
        )
    )
);

// Accessing data
echo $data['users'][0]['name']; // Outputs: John Doe
echo $data['products'][1]['price']; // Outputs: 75.00
