evaluating variables

[Anon]

let´s supose I have these variables:

$member_1="John";
$member_2="Paul";
$member_3="George";
$member_4="Ringo";
$qtn=4;

and I want to print them using a while loop:

$x=1;
while($x <= $qtn){
$name="$"."member_".$x;
echo $name;
$x++;
}

on this case I would have the following result:

$member_1
$member_2
$member_3
$member_4

instead of

John
Paul
George
Ringo

my question: how to print the value of $member_$x???

Check out the eval() function

Just as a general rule of thumb... this should be your last recourse.... generating dynamic code... Think of it as the goto statement in C. Its there you can use it but its a bad idea to use it. Unless its a special case.

Hope that Helps!
