Hello,

for the following options, I want to use variables like:

$switch = false;
$switch = true;

As Values for colums:

$col["hidden"] = false;
$col["hidden"] = true;

I think of using something like:

$col["hidden"] = $switch;
or:
$col["hidden"] = echo $switch;

However, it does not work, even if the variable byitself is working. But how do I integrate a variable as synonym for "true" or "false"? I plan to switch on or off a column by this variable.

Thanks for help
Mario
