MySQLI binding params using call_user_func_array

Question

Hello,

Please see below my code. I am attempting to bind an array of paramenters to my prepared statement. I've been looking around on the web and can see I have to use call_user_func_array but cannot get it to work. The error I get is: "First argument is expected to be a valid callback, 'Array' was given" I may be wrong but I'm assuming the first argument can be an an array and perhaps this error message is misleading. I think the issue is that my array is in someway at fault. Can anyone see what I am doing wrong? Thanks.

$type = array("s", "s");
$param = array("string1","anotherstring");

$stmt = $SQLConnection->prepare("INSERT INTO mytable (comp, addl) VALUES (?,?)");

$params = array_merge($type, $param);

call_user_func_array(array(&$stmt, 'bind_param'), $params);
$SQLConnection->execute();

I wouldn't know why you have to use call_user_func_array, but that's another story.

The only thing that could be wrong in my eyes is that you are using a reference to the object. Assuming you're using PHP 5.*, that is not necessary:

call_user_func_array(array($stmt, 'bind_param'), $params);
