php循环table实现一行两列显示的方法

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

结果：

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