What are some common pitfalls to avoid when using PHP to save webpage content regularly?

One common pitfall to avoid when using PHP to save webpage content regularly is not properly sanitizing user input, which can lead to security vulnerabilities such as SQL injection attacks. To solve this issue, always use prepared statements when interacting with a database to prevent malicious input from causing harm. 

// Example of using prepared statements to save webpage content securely

// Establish database connection
$pdo = new PDO('mysql:host=localhost;dbname=database', 'username', 'password');

// Prepare SQL statement
$stmt = $pdo->prepare("INSERT INTO webpage_content (content) VALUES (:content)");

// Bind parameters
$stmt->bindParam(':content', $content);

// Sanitize user input
$content = htmlspecialchars($_POST['content']);

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