HomeBackend DevelopmentPHP TutorialSmarty foreach控制循环次数的一些方法_php实例

1、在 smarty 中数组是经常会用到的,循环遍历数组用 section 或者 foreach ,如何得到数组长度或者判断一个数组个数呢?可以用{$array| count} 来试试。

2.

复制代码 代码如下:

{foreach from=$variable key=key name=name iteam=value}

    {$variable|@count}     // 获取数组长度

    {$smarty.foreach.loop.index}    // 获取当前循环数组元素下标,以0开始

    {$smarty.foreach.loop.iteration}    // 获取当前循环次数,以1开始

    {$smarty.foreach.loop.first}    // 为true时,标记循环第一次执行

    {$smarty.foreach.loop.last}    // 为true时,标记循环最后一次执行
 {$smarty.foreach.name.last}    // 为true时,标记循环最后一次执行

    {$smarty.foreach.loop.show}    // 当前是否显示

    {$smarty.foreach.loop.total}    // 循环次数

{/foreach}


3、控制循环次数
复制代码 代码如下:

{foreach name=infolist from=$VIDEO_INFO_LIST item=infolist}
{assign var=floor value=$smarty.foreach.infolist.index}
{if $floor  {*或者 if $smarty.foreach.infolist.iteration  
  • {$infolist%}

  • {/if}
    {/foreach}

    In PHP, iterating through session data can be achieved through the following steps: 1. Start the session using session_start(). 2. Iterate through foreach loop through all key-value pairs in the $_SESSION array. 3. When processing complex data structures, use is_array() or is_object() functions and use print_r() to output detailed information. 4. When optimizing traversal, paging can be used to avoid processing large amounts of data at one time. This will help you manage and use PHP session data more efficiently in your actual project.
