How can the issue of buggy and insecure code be addressed in PHP development?

The issue of buggy and insecure code in PHP development can be addressed by following best practices such as using secure coding techniques, regularly updating PHP versions, and implementing proper input validation and sanitization. 

// Example of input validation and sanitization in PHP
$user_input = $_POST['user_input'];

// Validate user input
if (filter_var($user_input, FILTER_VALIDATE_EMAIL)) {
    // Sanitize user input
    $sanitized_input = filter_var($user_input, FILTER_SANITIZE_STRING);
    
    // Use sanitized input in your code
    echo "Sanitized input: " . $sanitized_input;
} else {
    echo "Invalid input";
}
