How can multidimensional arrays be utilized more efficiently in PHP code to improve readability and maintainability?

Multidimensional arrays in PHP can be utilized more efficiently by using meaningful keys for each dimension, instead of relying solely on numerical indexes. This can improve readability and maintainability of the code by making it easier to understand the structure of the data being stored. Additionally, using associative arrays can help in accessing specific elements within the multidimensional array without having to rely on numerical indexes. 

// Example of utilizing associative arrays for multidimensional arrays in PHP
$data = [
    'user1' => [
        'name' => 'John Doe',
        'age' => 30,
        'email' => 'john.doe@example.com'
    ],
    'user2' => [
        'name' => 'Jane Smith',
        'age' => 25,
        'email' => 'jane.smith@example.com'
    ]
];

// Accessing specific user information
echo $data['user1']['name']; // Output: John Doe
