What are the potential errors that can arise when using PHP to handle dynamic content loading?

One potential error when using PHP to handle dynamic content loading is not properly sanitizing user input, which can lead to security vulnerabilities such as SQL injection or cross-site scripting attacks. To solve this, always validate and sanitize user input before using it in your PHP code. 

// Example of sanitizing user input using PHP
$user_input = $_POST['user_input'];
$clean_input = htmlspecialchars(strip_tags(trim($user_input));
