Question

I\'m trying to run the following query, and I\'m having trouble with the wildcard.

   function getStudents() {
        global $db;
        $users = array();
         


        

Answer 1

It is the same reason that happens in C++. When you pass a value to a function which expects the argument to be a reference, you need a variable ( not temporary ). So first create a variable and then pass it.
