• mysqli_fetch_assoc() expects parameter / Call to a member function bind_param() errors. How to get the actual mysql error? 1 answer

I am not really familiar with mysqli that much, and I have to upgrade my script to mysqli, please could you help me sort it?

I have this

function getConnected($host,$db_user,$db_password,$db) {

       $mysqli = new mysqli($host, $db_user, $$db_password, $db);

       if($mysqli->connect_error) 
         die('Connect Error (' . mysqli_connect_errno() . ') '. mysqli_connect_error());

       return $mysqli;
    }
    $mysqli = getConnected("localhost", "user_name_data456", "password123456", "user_database456");

and my query

        mysqli_query($mysqli,$sql);
        mysqli_query($mysqli,$sql2);
        mysqli_query($mysqli,$sql3);
        mysqli_query($mysqli,$sql4);
        mysqli_query($mysqli,$sql5);

The queries sql1 - 5 are working fine, it just has some insert things, I know doing more queries on mysql or mysqli isn't recommended, but I am just too tired.

Please help me sort it out. :/

Change this line

$mysqli = new mysqli($host, $db_user, $$db_password, $db);

to

$mysqli = new mysqli($host, $db_user, $db_password, $db);

removed extra $ from db_password variable
