How can one ensure the security of a PHP website while editing its content?

To ensure the security of a PHP website while editing its content, it is important to sanitize user input to prevent SQL injection and cross-site scripting attacks. This can be done by using functions like htmlspecialchars() or mysqli_real_escape_string() to escape special characters. Additionally, consider implementing input validation to ensure that only expected data types and formats are accepted. 

// Sanitize user input to prevent SQL injection and cross-site scripting attacks
$user_input = htmlspecialchars($_POST['user_input']);

// Validate user input to ensure expected data types and formats
if (filter_var($user_input, FILTER_VALIDATE_EMAIL)) {
    // Proceed with processing the input
} else {
    // Handle invalid input
}
