php 循环table，让内容一行两列显示

<table width="100%" border="0" cellspacing="1" cellpadding="0" style="background:#CCC">
<tr>
<td align="center" bgcolor="#FFFFFF">第一列</td>
<td align="center" bgcolor="#FFFFFF">第二列</td>
</tr>
<tr>
<?php
$setarr = array(0,1,2,3,4,5,6,7,8,9); //相当于数据库获取的数组
$i=0;
foreach($setarr as $val){
$i++;
?>
<?=$val?>
<?php
if($i%2==0&&$i<count($setarr)) echo '</tr><tr>';

} ?>
</tr>
</table>

如：是其他字符类型，需要用到函数转化：

<?php$str = "Hello world. It's a beautiful day.";print_r ([code]explode(" ",$str)

结果：

Array([0] => Hello[1] => world.[2] => It's[3] => a[4] => beautiful[5] => day.)
