What are the potential pitfalls of storing country outlines as coordinates in a database for use in PHP scripts?

Potential pitfalls of storing country outlines as coordinates in a database for use in PHP scripts include increased database size, slower query performance, and potential data inconsistencies if the coordinates are not accurately maintained. To solve these issues, consider using a more efficient data structure like GeoJSON or TopoJSON to store the country outlines and only retrieve the necessary data for each query. 

// Example of using GeoJSON to store country outlines and retrieve data
$country = 'USA';

// Retrieve GeoJSON data for the specified country from the database
$query = "SELECT geojson_data FROM country_outlines WHERE country_name = :country";
$stmt = $pdo->prepare($query);
$stmt->bindParam(':country', $country);
$stmt->execute();
$geojson = $stmt->fetchColumn();

// Parse the GeoJSON data and use it in your PHP script
$country_outline = json_decode($geojson, true);

// Use the country outline data in your PHP script
// (e.g., render it on a map or perform spatial analysis)
