PHP evaluating variables ?

[audas]

If I send multiple variables to a PHP script from flash say:
$test1
$test2
$test3
$test4
and I want to loop through these with a while count so say:
While($count<4){
$test.="$count";
$test (do something);
$count++;
}
how could this be done?
in Other words I want multiple vars with only number varying, and be able to use the aditition of the count to access the variables, unfortunately I am not good enough to work this out. Have tried everything.
Musicman??
Anyone??
I know this must have something to do with using a function, variable variables dont work, and when I use the function command it can not be set within the while loop,
cheers

$ordernum =& $GLOBALS["ordernum".$count];

You could also try something like this:

while($i<4){
     $i++;
     $_POST["test".$i] = "blah";
     echo $_POST[test1];
}

another one...

$varname = "test4";
now you can use $$varname

<?php

$test1 = 'This is';
$test2 = 'a sample';
$test3 = 'script that will';
$test4 = 'surely work!!';

$varPrefix = 'test';
$varIndex = 3;
$output = ${$varPrefix . $varIndex};

echo $output;

?>

[Output]
script that will

Ok, fisrt of all it has to be inside a loop of varying lengths, we do not know how many times it will loop, I have tried the variable variable inside a loop with a variable loop counter and it didnt like it.
But thanks anyway torray.
my solution seemed to work well.
