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.
    )
