in reply to @wowperfect's post:
does that look up a variable at runtime by name using the value of $var as the name?
like
$var = "x";
$x = "banana";
echo $$var;
will that print banana?
see i've never done php but it works exactly the same way in perl so i just assumed
what's weird is that classic bourne shell doesn't even have this feature, and bash has it under a different syntax!
var=x
x=banana
echo "${!var}"
because in bash $$ is a variable itself, so $$var means the $$ variable followed by var, and ${$var} is a syntax error for some reason!
