Are there any potential pitfalls to be aware of when ordering SQL output in PHP?

One potential pitfall when ordering SQL output in PHP is not properly sanitizing user input, which can lead to SQL injection attacks. To prevent this, always use prepared statements with parameterized queries to securely pass user input to the SQL query. 

// Connect to database
$pdo = new PDO('mysql:host=localhost;dbname=mydatabase', 'username', 'password');

// Prepare SQL statement with parameterized query
$stmt = $pdo->prepare('SELECT * FROM mytable WHERE column = :input ORDER BY id');
$input = $_GET['input']; // Assuming user input is passed through GET method
$stmt->bindParam(':input', $input);
$stmt->execute();

// Fetch and display results
while ($row = $stmt->fetch()) {
    echo $row['column_name'] . '<br>';
}
