What are the implications of sorting results in a MySQL query by ID in PHP?

When sorting results in a MySQL query by ID in PHP, it is important to ensure that the ID field is properly indexed in the database to improve query performance. Additionally, it is crucial to sanitize user input to prevent SQL injection attacks. Lastly, using prepared statements can help protect against SQL injection and improve code readability. 

// Example of sorting results in a MySQL query by ID in PHP
$mysqli = new mysqli("localhost", "username", "password", "database");

// Check connection
if($mysqli === false){
    die("ERROR: Could not connect. " . $mysqli->connect_error);
}

// Sanitize user input to prevent SQL injection
$id = $mysqli->real_escape_string($_GET['id']);

// Prepare a SQL statement
$sql = "SELECT * FROM table_name WHERE id = ? ORDER BY id";
$stmt = $mysqli->prepare($sql);

// Bind parameters
$stmt->bind_param("i", $id);

// Execute the statement
$stmt->execute();

// Get the result
$result = $stmt->get_result();

// Fetch the data
while ($row = $result->fetch_assoc()) {
    // Output data
    echo $row['column_name'] . "<br>";
}

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