What are best practices for organizing arrays in PHP to efficiently store and retrieve data?

When organizing arrays in PHP to efficiently store and retrieve data, it is important to use keys that are meaningful and unique. This allows for quick access to specific elements within the array. Additionally, consider using multi-dimensional arrays or associative arrays to group related data together. Lastly, avoid nesting arrays too deeply as it can make the code harder to read and maintain. 

// Example of organizing data efficiently in PHP using associative arrays
$user1 = [
    'id' => 1,
    'name' => 'John Doe',
    'email' => 'john@example.com'
];

$user2 = [
    'id' => 2,
    'name' => 'Jane Smith',
    'email' => 'jane@example.com'
];

$users = [
    $user1,
    $user2
];

// Accessing data efficiently
echo $users[0]['name']; // Output: John Doe
