What are the best practices for organizing and accessing data in PHP arrays for efficient retrieval?

When organizing and accessing data in PHP arrays for efficient retrieval, it is important to use associative arrays with meaningful keys to quickly access specific elements. Additionally, sorting arrays based on the keys or values can help in faster retrieval of data. Using multi-dimensional arrays or nested arrays can also help in organizing complex data structures for efficient access. 

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

// Accessing data efficiently
echo $data['user1']['name']; // Output: John Doe
echo $data['user2']['email']; // Output: jane.smith@example.com
