Question

How do it turn a multidimensional array like:

$fruits['apples']['blue'] = 24;
$fruits['bananas']['blue'] = 12;
$fruits['apple']['red'] = 34;
$fruits['gooseberries']['orange'] = 4;
$fruits['oranges']['red'] = 12;

into a cross referenced table like:

Answer 1

$cols = array('blue', 'red', 'orange');
echo '<table>';
echo '<thead><tr><td></td><th scope="col">' . implode('</th><th scope="col">', $cols) . '</th></tr></thead>';
echo '<tbody>';
foreach($fruits as $label => $row)
{
    echo '<tr>';
    echo '<th scope="row">' . $label . '</th>';
    foreach($cols as $k)
    {
      echo '<td>' . (isset($row[$k]) ? $row[$k] : 0) . '</td>';
    }
    echo '</tr>';
}
echo '</tbody>';
echo '</table>';

You’ll want some HTML escaping and such, but that’s the gist of it.
