How can PHP developers improve their code readability and maintainability when working with complex array structures?

PHP developers can improve code readability and maintainability when working with complex array structures by using meaningful variable names, breaking down complex operations into smaller, more manageable functions, and documenting their code effectively. Additionally, they can utilize PHP array functions like array_map, array_filter, and array_reduce to simplify array manipulation tasks. 

// Example of improving code readability and maintainability with complex array structures

// Define a meaningful variable name for the complex array
$users = [
    [
        'name' => 'John Doe',
        'age' => 30,
        'email' => 'john.doe@example.com',
    ],
    [
        'name' => 'Jane Smith',
        'age' => 25,
        'email' => 'jane.smith@example.com',
    ],
    // more user data...
];

// Use array_map to extract only the names of users
$userNames = array_map(function($user) {
    return $user['name'];
}, $users);

// Output the extracted user names
print_r($userNames);
