What are the potential challenges or pitfalls to be aware of when sorting and displaying data in PHP?

One potential challenge when sorting and displaying data in PHP is ensuring that the data is properly formatted and sanitized to prevent any security risks such as SQL injection attacks. To solve this, always use prepared statements when interacting with a database to prevent malicious input from affecting the query. 

// Example of using prepared statements to retrieve and display data from a database
$stmt = $pdo->prepare("SELECT * FROM table WHERE id = :id");
$stmt->bindParam(':id', $id, PDO::PARAM_INT);
$stmt->execute();

while ($row = $stmt->fetch(PDO::FETCH_ASSOC)) {
    // Display data here
}
