How can you modify the existing res() function to handle different types of queries in PHP?

The existing res() function may need to be modified to handle different types of queries in PHP by adding conditional statements to check the type of query being executed and then executing the appropriate code block based on the query type. This can be achieved by using if-else or switch-case statements to differentiate between different query types and perform the necessary actions accordingly. 

function res($query, $type) {
    // Check the type of query and execute the appropriate code block
    if($type == 'select') {
        // Code block for SELECT query
        $result = mysqli_query($connection, $query);
        // Process the result
    } elseif($type == 'insert') {
        // Code block for INSERT query
        $result = mysqli_query($connection, $query);
        // Check if the query was successful
    } elseif($type == 'update') {
        // Code block for UPDATE query
        $result = mysqli_query($connection, $query);
        // Check if the query was successful
    } else {
        // Handle other types of queries
    }
}
