Dynamically get $_POST

[wemustdesign]

I am using the Paypal ipn to add bought products to my database. So I have posted my products to Pyapl fine. I am having trouble getting the variables dy7namically in the IPN. I can do it manually fine like this:

 

$item_number1 = $_POST['item_number1'];

$item_number2 = $_POST['item_number2'];

....................

 

I need to dynamically create the above. I thought the while loop below would work but I am not sure if this is how you would do this, or if I have the correct syntax:

 

$dc=1;

while($dc <= $num_cart_items){

echo "$item_number$dc = $_POST['item_number$dc']";

$dc++;

<?php

$a['item_number1']='1111';
$a['item_number2']='2222';
$a['item_number3']='3333';
$a['item_number4']='4444';

$dc='1';
while($dc <=4) {
        ${"item_number{$dc}"} = $a["item_number$dc"];
        $dc++;
}

print $item_number1."<br>\n";
print $item_number2."<br>\n";
print $item_number3."<br>\n";
print $item_number4."<br>\n";

?>

This should do the trick.

for($dc = 1; $dc    $theIndex = "item_number" . $dc;
   echo ${$theIndex} = $_POST[$theIndex];
}
