What are the potential risks of using outdated PHP tutorials that do not include proper security measures like escaping inputs?

Using outdated PHP tutorials that do not include proper security measures like escaping inputs can leave your application vulnerable to SQL injection attacks. To solve this issue, always sanitize and validate user inputs before using them in database queries or other operations. 

// Example of sanitizing user input using mysqli_real_escape_string
$input = $_POST['input'];
$clean_input = mysqli_real_escape_string($connection, $input);
