<tablewidth="100%"border="0"cellspacing="1"cellpadding="0"style="background:#CCC"><tr><tdalign="center"bg
<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>
<?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
$str = "Hello world. It's a beautiful day.";
print_r (explode(" ",$str));
?>结果：
Array
(
[0] => Hello
[1] => world.
[2] => It's
[3] => a
[4] => beautiful
[5] => day.
)
