What are some best practices for managing arrays with empty fields in PHP?

When managing arrays with empty fields in PHP, it's important to handle these empty fields properly to avoid unexpected behavior in your code. One common approach is to check if a field is empty before accessing its value to prevent errors or inconsistencies in your application. 

// Example code snippet for managing arrays with empty fields in PHP

$data = [

    'age' => null,
    'email' => '',

];

// Loop through the array and handle empty fields
foreach ($data as $key => $value) {
    if (!empty($value)) {
        echo "$key: $value\n";
    } else {
        echo "$key: N/A\n";
    }
}
