Are there any potential pitfalls in using prepared statements with PDO in PHP, especially when dealing with LIMIT clauses?

When using prepared statements with PDO in PHP, it's important to be cautious when dealing with LIMIT clauses to prevent potential SQL injection vulnerabilities. To safely use LIMIT clauses with prepared statements, you can bind the LIMIT value as a parameter in the query to ensure it is properly escaped and sanitized. 

// Example of using a prepared statement with a LIMIT clause in PDO
$limit = 10; // Example limit value

// Prepare the query with a placeholder for the LIMIT value
$stmt = $pdo->prepare("SELECT * FROM table_name LIMIT :limit");

// Bind the LIMIT value as a parameter
$stmt->bindParam(':limit', $limit, PDO::PARAM_INT);

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

// Fetch the results
$results = $stmt->fetchAll();
