直接foreach 计数 或者用array_chunk 分段都是可以实现的

定义一个变量$p=0; 每次循环完$p++;
if($p%4==0) 分段.

直接foreach 计数 或者用array_chunk 分段都是可以实现的


我现在是用计数的,效果不理想,分页不方便,所以想截取,

求:array_chunk 实例

http://www.w3school.com.cn/php/func_array_chunk.asp

不一定非要拆分数组或计数
只需将每个条目定宽并浮动,即可在外容器内分栏排列了
只不过次序是 从左到右,从上到下
而不是你示意的 从上到下,从左到右

这是在谷歌浏览器下的现实。设置好ul和li的宽度就可以实现任意列了
写样式要注意浏览器的兼容性问题,譬如ie的忘记那个版本了是不支持inline-block的,需要写hack

多行多列最好不要用列表,用table比较省事
test.php
  
             $arr=array(1,2,3,4,5,6,7,8,9,10,11,12,13,14);
         $has_n_cols=3;  //现实几列
         $count=count($arr);
         $timer=1;
         foreach($arr as $value)
         {
                if($timer%$has_n_cols==1)
                 {
                    echo "\n";
                 }
    
                 echo "\n";
                if($timer%$has_n_cols==0 or $timer==$count)
{
                     echo "\n";
                }
            $timer++;
         }

    ?>

$value


不知道楼主有没有在用smarty模板技术 如果在用的话,给foreach起个名字

..(每循环5次 做什么 换行或者其他)..

我觉得浮动的方式是最好的。

<style type="text/css">   ul,li{padding:0px;margin:0px;}   ul {list-style:none;width:156px; background:green;}   li {width:50px; background:red;float:left;margin-left:10px;display:inline;}</style><ul>  <li>1 </li>  <li>2 </li>  <li>3 </li>  <li>4 </li>  <li>5</li>  <li>6 </li>  <li>7 </li>  <li>8 </li>  <li>9 </li>  <li>10 </li>  <div style="clear:both;"></div></ul>
Copy after login
 

介个啊 css布局好了 直接输出到底。。。

直接一个if判断即可,每隔5列就换行,换行的话,直接tr标签。
