What are best practices for structuring PHP code to improve database interactions and prevent errors like the one mentioned in the forum thread?

Issue: The error mentioned in the forum thread is likely due to improper handling of database connections and queries in the PHP code. To prevent such errors and improve database interactions, it is recommended to use prepared statements to prevent SQL injection attacks, properly handle errors, and close database connections after use. PHP Code Snippet: 

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

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

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

// Use prepared statements to prevent SQL injection
$stmt = $conn->prepare("SELECT * FROM table_name WHERE id = ?");
$stmt->bind_param("i", $id);

$id = 1; // Example value for the id parameter
$stmt->execute();
$result = $stmt->get_result();

// Handle errors and fetch data
if ($result->num_rows > 0) {
    while($row = $result->fetch_assoc()) {
        // Process the data
    }
} else {
    echo "No results found";
}

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