How can PHP developers ensure code quality and avoid reliance on questionable resources for scripting?

To ensure code quality and avoid reliance on questionable resources for scripting, PHP developers should follow best practices such as using secure coding techniques, regularly reviewing and testing code, and avoiding the use of deprecated functions or insecure libraries. Additionally, developers should stay updated on PHP security advisories and guidelines to maintain a secure codebase. 

// Example code snippet demonstrating secure coding techniques
$user_input = $_POST['user_input']; // Sanitize user input to prevent SQL injection
$filtered_input = filter_var($user_input, FILTER_SANITIZE_STRING);
$query = "SELECT * FROM users WHERE username = '$filtered_input'";
$result = mysqli_query($connection, $query);

// Regularly review and test code to identify and fix vulnerabilities
// Avoid using deprecated functions or insecure libraries
// Stay updated on PHP security advisories and guidelines
