Are there any best practices for handling pagination in PHP to avoid such issues?

When handling pagination in PHP, it is important to properly sanitize and validate user input to prevent SQL injection attacks and other security vulnerabilities. One common best practice is to use prepared statements with bound parameters when querying the database to ensure safe and secure pagination functionality. 

// Validate and sanitize user input for pagination
$page = isset($_GET['page']) ? filter_var($_GET['page'], FILTER_VALIDATE_INT) : 1;
$perPage = 10;

// Calculate offset for pagination
$offset = ($page - 1) * $perPage;

// Prepare and execute SQL query using prepared statements
$stmt = $pdo->prepare("SELECT * FROM table LIMIT :offset, :perPage");
$stmt->bindParam(':offset', $offset, PDO::PARAM_INT);
$stmt->bindParam(':perPage', $perPage, PDO::PARAM_INT);
$stmt->execute();

// Fetch and display paginated results
$results = $stmt->fetchAll();
foreach ($results as $result) {
    // Display result
}
