For that to work, you had to had made a multidimensional array, which had most
likely been the easiest for you.

All those are really meaningless tries, you are still trying to add together
the variable $line_, $i and $pos.

This is how you have to do it, you save the variable name you want to use into
a string and from there use it, not completely sure which will be the right
"syntax", but you can try.

--- first ---
$variabletouse="line_$i";
echo $$variabletouse[$pos];
--- eof ---

--- second ---
$variabletouse="line_$i[$pos]";
echo $$variabletouse;
--- eof ---

Notice the double $ in front of the variable, this makes PHP to use the string
as the variable name.
