Are there any best practices to follow when using PHP to retrieve and display data from a database on a map?

When using PHP to retrieve and display data from a database on a map, it is important to sanitize user input to prevent SQL injection attacks. Additionally, it is recommended to use prepared statements to securely query the database. Finally, make sure to properly format the data retrieved from the database before displaying it on the map. 

<?php
// Establish a database connection
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";

$conn = new mysqli($servername, $username, $password, $dbname);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

// Sanitize user input
$user_input = mysqli_real_escape_string($conn, $_POST['user_input']);

// Prepare a SQL statement
$stmt = $conn->prepare("SELECT * FROM locations WHERE name = ?");
$stmt->bind_param("s", $user_input);
$stmt->execute();
$result = $stmt->get_result();

// Fetch and display data on the map
while ($row = $result->fetch_assoc()) {
    echo "Latitude: " . $row['latitude'] . ", Longitude: " . $row['longitude'] . "<br>";
}

// Close the database connection
$stmt->close();
$conn->close();
?>
