[Resolved] a variable variable problem

[helz]

in the ratings part of my current project, i have 6 variables:
$rat_0
$rat_1
$rat_2
$rat_3
$rat_4
$rat_5

now instead of doing 6 seperate if statements i want to use a
for() loop so that the number after the underscore can be automatic...

eg:

for($i=0;$i<=5;$i++) {// loop 6 times until $i is equal to 5
   $rat_$i;
}

how can i make it so that the number after the underscore is automatic and then use that number to complete the rest of the name of the variable?

for($i=0;$i<=5;$i++) {
   $cur_rat = 'rat_' . $i;
   $$cur_rat;
}

i had a feeling it envolved double $$

so if i wanted to add an if statement into the for loop. do i just do:

if ($cur_rat > 0) {

and for each time it loops $cur_rat will hold the value of $rat_0 thru $rat_5?

i changed it to:

if ($$cur_rat > 0)

works fine now..

thanks again mack
