Foreach up one number for each

Struggling a little on this one.

This is my foreach code

<?php
$subtotal = 0;
foreach ($go_cart['contents'] as $cartkey=>$product):?>

        <td><input type="hidden" name="itemdescription_0" value="Description" /></td>

<?php endforeach; ?>

And for this line

<td><input type="hidden" name="itemdescription_0" value="Description" /></td>

I need it to up by one for each foreach. Such as:

<td><input type="hidden" name="itemdescription_0" value="Description" /></td>
<td><input type="hidden" name="itemdescription_1" value="Description" /></td>
<td><input type="hidden" name="itemdescription_2" value="Description" /></td>

I'm pretty sure you have the quick solution for me on this one...

Thanks guys!, appreciate it.

HERE IS WHAT I FORGOT TO MENTION:

I have multiple fields for this action. So i have description, itemcount, itemamount etc.

So they should be like this

<td><input type="hidden" name="itemdescription_0" value="Description" /></td>
<td><input type="hidden" name="itemcount_0" value="Description" /></td>
<td><input type="hidden" name="itemamount_0" value="Description" /></td>

But with the solution you sent me i get.

<td><input type="hidden" name="itemdescription_1" value="Description" /></td>
<td><input type="hidden" name="itemcount_2" value="Description" /></td>
<td><input type="hidden" name="itemamount_3" value="Description" /></td>

Sorry, my mistake!...

Change:

$subtotal = 0;

to

$subtotal = 0;
$i = 0;

Then do the following:

<td><input type="hidden" name="itemdescription_<?php echo $i; ?>" value="Description" /></td>
<td><input type="hidden" name="itemcount_<?php echo $i; ?>" value="Description" /></td>
<td><input type="hidden" name="itemamount_<?php echo $i; ?>" value="Description" /></td>

Right BEFORE you close your outer foreach() loop do this on its own line:

$i++;

What you are doing is first initializing the variable $i by setting it to 0. You then output the current value of $i. Then you will use the post-increment operator with $i as $i++ at the end of your loop to increase its value by 1 so the next time it is output on next run of the loop it will be increased by 1.

Here's the code

<?php
for ($i=0; $i<=2; $i++)
  {
  echo "<td><input type=\"hidden\" name=\"itemdescription_" . $i . "value=\"Description\" /></td>"."\n";
  }
?>
