how do I get array index number in php?

[cravetm]

I'm sure this is a stupid question, but it's Friday and my brain just can't figure it out. I have an array of arrays, like so:\[code\]$cart = Array ( [0] => Array ( [TypeFlag] => S [qty] => 2 [denom] => 50 [totalPrice] => 100 )[1] => Array ( [TypeFlag] => V [qty] => 1 [denom] => 25 [totalPrice] => 25 ) ) \[/code\]I'm looping through this array and printing out table rows, one for each internal array. This part works fine. I now need to include a link in one table cell that contains the actual index number of the internal array, so that I can run specific functions on that array. I know how to access a specific array element, like $cart[0], but how can I get the actual zero when I'm writing my links? The loop to write the table currently looks like this:\[code\] foreach($this->cart as $value) { $finalTotal += $value['totalPrice']; echo "<tr>"; foreach($value as $key=>$item) { //create a new row for each internal array element echo "<td>".$item."&nbsp;</td>"; } //now add a link for each external array element echo "<td><a href=http://stackoverflow.com/"myFunction(arrayIndex)\">Delete</a></td></tr>"; }\[/code\]What I need to do is replace the arrayIndex param in the myFunction with the actual index number of the currently-looping array, so that, given the example array, I'd end up with table code that looked like this:\[code\]<tr> <td>S</td> <td>2</td> <td>50</td> <td>100</td> <td><a href="http://stackoverflow.com/questions/3789339/myFunction(0)">Delete</a></td></tr><tr> <td>V</td> <td>1</td> <td>25</td> <td>25</td> <td><a href="http://stackoverflow.com/questions/3789339/myFunction(1)">Delete</a></td></tr>\[/code\]Can anyone please give my poor brain a jumpstart?
