How can PHP developers ensure they are using arrays effectively in their code?

PHP developers can ensure they are using arrays effectively in their code by properly understanding array functions and methods, avoiding unnecessary loops, and utilizing associative arrays for key-value pairs. They should also consider using multi-dimensional arrays for complex data structures. 

// Example of using associative arrays for key-value pairs
$user = [
    'name' => 'John Doe',
    'email' => 'johndoe@example.com',
    'age' => 30
];

// Example of using multi-dimensional arrays
$users = [
    [
        'name' => 'John Doe',
        'email' => 'johndoe@example.com',
        'age' => 30
    ],
    [
        'name' => 'Jane Smith',
        'email' => 'janesmith@example.com',
        'age' => 25
    ]
];
