What is the equivalent of bind_result on PDO

Question

I\'m converting to PDO and Im using prepared statements, I want to bind my result as so $stmt->bind_result($email_count); so i am able to put this into an if

Answer 1

Here's my custom function:

function bindColumns($stmt, $columns){
    if(!is_array($columns)) $columns=array($columns);
    $count=count($columns);
    for($i=0;$i<$count;$i++) $stmt->bindColumn($i+1, $columns[$i]);
}

And usage (variables by reference):

bindColumns($stmt, array(&$worker_id, &$password, &$salt));
