HomeBackend DevelopmentPHP Tutorialsmarty模板引擎使用内建函数foreach循环取出所有数组值的方法_php实例

本文实例讲述了smarty内建函数foreach的使用方法,分享给大家供大家参考。具体如下:

显示文件:index.php:

复制代码 代码如下:
//创建smarty对象
require_once("./libs/Smarty.class.php");
$smarty = new Smarty();

$arr1 = array("北京","上海","广州");//索引数组
$smarty->assign("arr1",$arr1);//分配索引数组
$arr2 = array("city1"=>"北京","city2"=>"上海","city3"=>"广州");//关联数组
$smarty->assign("arr2",$arr2);//分配关联数组
$arr3 = array(array("北京","上海","广州"),array("关羽","张飞","美女"));//二维索引数组
$smarty->assign("arr3",$arr3);
$arr4 = array(array("c1"=>"北京","c2"=>"上海","c3"=>"广州"),array("n1"=>"关羽","n2"=>"张飞","n3"=>"美女"));//二维关联数组
$smarty->assign("arr4",$arr4);

$smarty->display("temp.tpl");
?>

模板文件:temp.tpl

复制代码 代码如下:

smarty内建函数foreach,循环取出数组值


实例1:一维索引数组


{foreach from=$arr1 item=temp}
{$temp}
{/foreach}

实例2:一维关联数组——>item为键值,key为键名。如果不取key,取出方法与一维索引数组相同,当然索引数组也是有key的0,1,2...


{foreach from=$arr2 item=temp key=k}
{$k}={$temp}
{/foreach}

实例3:二维索引数组——>两次循环即可


{foreach from=$arr3 item=temp}
 {foreach from=$temp item=value}
  {$value}
 {/foreach}

{/foreach}

实例4:二维关联数组——>同样两次循环即可


{foreach from=$arr4 item=temp}
 {foreach from=$temp item=value key=k}
  {$k}={$value}
 {/foreach}

{/foreach}

What is the difference between absolute and idle session timeouts?What is the difference between absolute and idle session timeouts?May 03, 2025 am 12:21 AM

Absolute session timeout starts at the time of session creation, while an idle session timeout starts at the time of user's no operation. Absolute session timeout is suitable for scenarios where strict control of the session life cycle is required, such as financial applications; idle session timeout is suitable for applications that want users to keep their session active for a long time, such as social media.

The server session failure can be solved through the following steps: 1. Check the server configuration to ensure that the session is set correctly. 2. Verify client cookies, confirm that the browser supports it and send it correctly. 3. Check session storage services, such as Redis, to ensure that they are running normally. 4. Review the application code to ensure the correct session logic. Through these steps, conversation problems can be effectively diagnosed and repaired and user experience can be improved.

Setting the httponly flag is crucial for session cookies because it can effectively prevent XSS attacks and protect user session information. Specifically, 1) the httponly flag prevents JavaScript from accessing cookies, 2) the flag can be set through setcookies and make_response in PHP and Flask, 3) Although it cannot be prevented from all attacks, it should be part of the overall security policy.

Session regeneration refers to generating a new session ID and invalidating the old ID when the user performs sensitive operations in case of session fixed attacks. The implementation steps include: 1. Detect sensitive operations, 2. Generate new session ID, 3. Destroy old session ID, 4. Update user-side session information.
