Answer 1

If i m not wrong this should do the trick!
my array:
$array = array(
'group1' => array(
'aaa',
'bbb',
'ccc'
),
'group2' => array(
'ddd',
'eee',
'fff'
)
);
Working code:
echo '
<table border="1">
<thead>';
foreach($array AS $tname => $tvalue){
echo '<th>'.$tname.'</th>';
}
echo '
</thead>
<tbody>';
$keys = array_keys($array);
$first_key = $keys[0];
foreach ($array[$first_key] as $id => $value) {
$body .= "<tr>";
foreach ($keys as $k) {
$body .= "<td>" . $array[$k][$id] . "</td>";
}
$body .= "</tr>";
}
echo $body;
echo '
</tbody>
</table>';
