How to take multiple input from user in php

Question

To summarize from a previous question, the user selected a starting date, an ending date, and a region. From these choices, an array of weeks and regions are created, and users enter values ("points") that correspond to a particular week and region. This is what it looks like right now (some parts are hard-coded for testing purposes):

$date_array = Array("01/01/2012", "01/08/2012", "01/15/2012");
$region_array = Array("NYC", "DC");

<form name="test_form" id="test_form" method="post">
<table border="1">
    <tr>
        <td></td>
        <?php
            foreach ($date_array as $date)
                {
                echo "<td>".$date."</td>";
                }
        ?>
    </tr>
    <?php
    foreach ($region_array as $region)
        {
        echo "<tr>";
        echo "<td>".$region."</td>";
        foreach ($date_array as $date)
            {
            echo '<td><input type="text" name='.$region."-value1_".$date.'><input type="text" name='.$region."-value2_".$date.'></td>';

            }
        echo "</tr>";
        }
    ?>
</table>
<input type="submit" name="submit">

And the next part:

if (isset($_POST['submit']))
{
    foreach ($_POST as $k=>$v)
    {
    if ($k != "submit") // use even and odd count to differentiate TRP and CPP
        {
        // split the form input on _
        $input = explode("_", $k);
        echo "<BR>Region: " . $input[0];
        echo "<BR>Date: " . $input[1];
        echo "<BR>Value: " . $v;
        }
    echo "<br/>";
    }
}

So basically, in this example it outputs 12 times:

Region: NYC-value1
Date: 01/01/2012
Value: 500

Region: NYC-value2
Date: 01/01/2012
Value: 5

Region: NYC-value1
Date: 01/08/2012
Value: 600

I want to catch the value1 and value2 while the loop is running, but as it stands it loops through both of them before going onto the next date/region. My idea, as I put in comments, was to have a counter of even and odd numbers and simply tell if it was doing value1 or value2 based on that.

Is this a good idea or am I missing something fundamentally simpler?
