feeding dynamic variable names into $_POST

Question

isset($_POST['"$daysofweek[i]"'])

I tried different variations but i can't get it to detect. I have an array with all the days of the week and I want to check every POST variable.

It's probably really simple, but im stuck.

Thanks

What does $_POST actually have in it? What does $daysofweek have in it? Where does i come from and shouldn't it be $i? You do know what single quoted strings do not interpolate, so that code is looking for <input name=""$daysofweek[i]""> (with no PHP operating at all on that HTML fragment) — Quentin

Assuming $i is also a PHP variable (in a loop maybe):

isset($_POST[$daysofweek[$i]])

@Adam: I just happen to be about to head the other direction (PHP -> ActionScript)
