如何在php循环中每行显示两个表列

<?php
$items = array('Item 1', 'Item 2', 'Item 3', 'Item 4', 'Item 5', 'Item 6');
$count = 0;

echo<table>';
foreach ($items as $item) {
    if ($count % 2 == 0) {
        echo '<tr>';
    }
    echo '<td>' . $item . '</td>';
    if ($count % 2 == 1) {
        echo '</tr>';
    }
    $count++;
}
if ($count % 2 == 1) {
    echo '<td></td></tr>';
}
echo '</table>';
?>
