How can PHP developers optimize the process of defining and storing country borders for use in mapping applications without relying on external frameworks like Leafnode or OpenLayers?

To optimize the process of defining and storing country borders in PHP for mapping applications, developers can create a custom database table to store the border coordinates of each country. By querying this table, developers can efficiently retrieve the border data and use it to display country boundaries on maps without relying on external frameworks like Leafnode or OpenLayers. 

// Create a custom database table to store country borders
// Example SQL query to create the table:
// CREATE TABLE country_borders (
//     id INT AUTO_INCREMENT PRIMARY KEY,
//     country_code VARCHAR(2) NOT NULL,
//     border_coordinates TEXT NOT NULL
// );

// Function to retrieve border coordinates for a specific country
function getCountryBorderCoordinates($countryCode) {
    $db = new PDO('mysql:host=localhost;dbname=your_database_name', 'username', 'password');
    $stmt = $db->prepare('SELECT border_coordinates FROM country_borders WHERE country_code = :countryCode');
    $stmt->bindParam(':countryCode', $countryCode);
    $stmt->execute();
    $result = $stmt->fetch(PDO::FETCH_ASSOC);
    
    return json_decode($result['border_coordinates'], true);
}

// Example usage
$countryCode = 'US';
$borderCoordinates = getCountryBorderCoordinates($countryCode);
// Use $borderCoordinates to display country border on map
