How can one adapt their PHP code to comply with the new standards regarding deprecated mysql_ functions?

The issue arises from the deprecation of mysql_ functions in PHP, which can lead to security vulnerabilities and compatibility issues. To comply with the new standards, one should switch to using mysqli or PDO for database operations. By updating the code to use these modern alternatives, the application will be more secure and future-proof. 

// Before:
$conn = mysql_connect('localhost', 'username', 'password');
mysql_select_db('database_name', $conn);
$result = mysql_query('SELECT * FROM table', $conn);

// After:
$conn = mysqli_connect('localhost', 'username', 'password', 'database_name');
$result = mysqli_query($conn, 'SELECT * FROM table');
