How to POST data as an indexed array of arrays (without specifying indexes)

Question

i\'m having some problem with posting data as an array of array. This is how i\'d like my data to be POSTED:

array(
[\'someName\'] =>
array([0] =>

Do it the way you put in the question. If the user removes some row, your form elements would be:

But there's no problem to traverse an array with non-contiguous numeric indexes in php: use a foreach loop.

 0)
{
    foreach ($_POST['somename'] as $row)
    {
        echo "Value: ".$row['value']."
\n";
        echo "Description: ".$row['description']."
\n";
    }
}

If you need to know the number of each row as a continous index (in the example provided, row 0 would still be 0, but row 2 should be 1 (as the user deleted one row), you can use a variable acting as a counter:

 0)
{
    $i = 0;
    foreach ($_POST['somename'] as $row)
    {
        echo "Index $i
\n";
        echo "Value: ".$row['value']."
\n";
        echo "Description: ".$row['description']."
\n";
        $i++;
    }
}

I think this approach has more sense that the other solutions, as this way you would have an array of items, being each item a value and a description, instead of having two separate arrays of values and descriptions and having to get the values for your item from those two arrays instead of one.

edit: I've modified the first piece of code to include the

element. This would be the accompanying js function:
