What potential issue with pagination in PHP is highlighted in the provided code snippet?

The potential issue with pagination in the provided code snippet is that the `$page` variable is not properly sanitized before being used in the SQL query, which can make the application vulnerable to SQL injection attacks. To solve this issue, it is important to sanitize user input before using it in a SQL query to prevent any malicious code execution. 

// Sanitize the $page variable before using it in the SQL query
$page = isset($_GET['page']) ? intval($_GET['page']) : 1;

// Ensure $page is always a positive integer
$page = max(1, $page);

// Use prepared statements to safely handle user input in the SQL query
$stmt = $pdo->prepare("SELECT * FROM table LIMIT :offset, :limit");
$limit = 10;
$offset = ($page - 1) * $limit;
$stmt->bindParam(':offset', $offset, PDO::PARAM_INT);
$stmt->bindParam(':limit', $limit, PDO::PARAM_INT);
$stmt->execute();
