数组合和发布

Question

This is a follow-up question to my previous post about array posting. I was advised to combine my arrays in order to dynamically generate table results for an email. So far, it looks like this:

$emp_names = is_array($_POST['emp_name']) ? $_POST['emp_name'] : array($_POST['emp_name']);
$emp_today_results = is_array($_POST['emp_today_result']) ? $_POST['emp_today_result'] : array($_POST['emp_today_result']);
$emp_today_goals = is_array($_POST['emp_today_goal']) ? $_POST['emp_today_goal'] : array($_POST['emp_today_goal']);
$emp_month_results = is_array($_POST['emp_month_result']) ? $_POST['emp_month_result'] : array($_POST['emp_month_result']);
$emp_month_goals = is_array($_POST['emp_month_goal']) ? $_POST['emp_month_goal'] : array($_POST['emp_month_goal']);
$emp_month_trends = is_array($_POST['emp_month_trend']) ? $_POST['emp_month_trend'] : array($_POST['emp_month_trend']);

$emp_results = array_combine($emp_names, $emp_today_results, $emp_today_goals, $emp_month_results, $emp_month_goals, $emp_month_trends);

That collects and combines all the arrays. Then, I don't now how to use them. This doesn't work (I assume because there is no "as" in the brackets. Any idea how to make it work?

foreach ($emp_results) {
        $htmlBody .= "

        <tr>
        <td>{$emp_name}</td>
        <td>{$emp_today_result}</td>
        <td>{$emp_today_goal}</td>
        <td>{$emp_month_result}</td>
        <td>{$emp_month_goal}</td>
        <td>{$emp_month_trend}</td>
        </tr>";

        }

$values = explode('|', 'emp_name|emp_today_result|emp_today_goal|emp_month_result|emp_month_goal|emp_month_trend');
foreach ($values as $value) {
    $$value = (array)$_POST[$value];
}
for ($i = 0; $i < count($emp_name); $i++) {
    $emp_results = array();
    foreach ($values as $value) {
        $emp_results[] = ${$value}[$i];
    }
    $htmlBody .= '<tr><td>' . implode('</td><td>', $emp_results) . '</td></tr>';
}
