Using mysqli_stmt_bind_param in a class - with variable parameters?

Hi all, I would like to ask you if anyone of you ever did something like that or might tell me how to do this. I am currently switching from PHP4 to PHP5 and mySQL4 to mySQL5. On account of this, I would like to use the improvements of ext/mysqli instead of the old ext/mysql. So I need to do a rewrite on my database class and as of this, I would like to add new functions such as prepared statements, which are obviously supported by mysqli. In fact, I would like to write a method within my class like this: public function bindParam($str_types, &$var_variable) {

    // Code
    $mysqli_stmt->bind_param($str_types, $var_variable);

} This method is supposed to be called like this ($result is an object of that class) $result->bindParam("s", $username); $username = "username"; That does work out already, but I would like to add more parameters like this: $result->bind_param("ssss", $username, $email, $me, $you); As I don't want to write a method with 50 optional parameters (I needed to add one if I were to use 51 variables), I would like to solve this problem dynamically. In fact, I tried to recall the bind_param method of mysqli_stmt several times, but I have to call it only once as PHP requires me to do this. (I get an error otherwise that the number of variables isn't fitting to the prepared statement) So I have to pass all parameters in one call. I also tried eval() but that didn't really work out, either. Now, my question is: What can I do to solve this problem? Is there any elegant way of doing this? Thanks in advance for any inspiration (and I hope I could make myself clear). Yours sincerely Christian Heinrich
