[simple question] dynamic variables and POST-method

[strange1]

I have a form with a textfield which is dynamically written depending on the amount of variables needed.

An example:

<form name="test" method="post" action="test.php">

<?
$number = 0;
while ($number >= 10) { ?>

<input type="text" value="test <?= $number?>" name="test_<?= $number ?>">
<? $number++; ?>

<? } ?>
<input type="submit">
</form>

How can I read the variables I get on test.php from this form dynamically?

If I refer to $test_$nr and $nr = 1 it doesn't grap the $test_1 variable...

use e.g.

$_POST['$test_4']

no, I want to read it out dynamically...

so you want to post to a page that doesnt know how many post vars are coming, and adapts accordingly.

ie. u need to be able to check how many rows are in the post array.

how about this ?

<form name="test" method="post" action="test2.php"> 

<? 
foreach($_POST as $key => $value) {
       $varname = $key;
       $$varname = $value;
}

$nr=4;
$x='test_';


echo "" . ${$x.$nr};

$number = 0;
while ($number <= 10) { ?> 

<input type="text" value="test <?= $number?>" name="test_<?= $number ?>"> 
<? $number++; ?> 

<? } ?> 
<input type="submit"> 
</form>

I managed to do it simpler using the $_REQUEST method.

But thanks for your alternatives! Will look forward to em
