Variable variables?

[wmhop]

I'm not sure if the solution to this is to use variable variables or not but I just couldn't figure out how to make it work. Here's basically what I'm trying to do. I'm passing the $loop_counter into my function and I want the variables $row_cd1_questions and $result_cd1_questions to change based on the value of $loop_counter. So for instance when $loop_counter is 2 then $row_cd1_questions would become $row_cd2_questions.

			
function display_client_specific_questions($loop_counter){

    while ($row_cd1_questions = $result_cd1_questions->fetch_object()){ 
   		do stuff...
    }

}

for ($loop_counter = 1; $loop_counter <= 4; $loop_counter ++){
    display_client_specific_questions($loop_counter);
}

Thanks for any assistance.

Read the PHP manual on variable variables.

Yes, you may be able to use variable variables here, but of course those variables have to be in the scope of the function. You might also consider using arrays instead, e.g., $row_cd_questions[$loop_counter] instead of ${'row_cd' . $loop_counter . '_questions'}.

I'll give both of these a try. I read the manual on variable variables but couldn't figure out how to make them work for my situation.

I did something funky like this:
$row_cd = 'row_cd';
$$row_cd .= $loop_counter.'_questions';

I think I was pursuing the wrong solution.

By the way laserlight, thanks for the help. You've actually given me an idea on a way to rework another section of my code also.
