php 如何获取JS的值 ,新手折腾几天了 还请大侠赐教!
请问以下代码如何修改才能得到 $key 值
<script type="text/javascript"> TOP.api('rest', 'get', { //method:'taobao.taobaoke.items.convert', method : 'taobao.taobaoke.widget.items.convert', num_iids : '<?=$id?>', fields : 'num_iid,click_url,commission_rate' }, function(resp) { if(resp.error_response) { alert('taobao.taobaoke.widget.items.convert接口获取商信息品失败!' + resp.error_response.msg); return false; } var respItem = resp.taobaoke_items.taobaoke_item; for(var i = 0; i < respItem.length; i++) { abc=respItem[i].num_iid; } }) </script> <? $key="<script>document.write(abc);</script>"; echo $key; //请问大侠们如何修改这里才能得到值 感激不尽! ?>
------解决方案--------------------
没可能。PHP是服务器端语言,JS是浏览器端语言。apache先执行PHP代码,解析成HTML代码后下载到用户的浏览器,浏览器再执行JS语言进一步渲染。所以当你的代码运行先运行PHP,再运行TOP.api,等执行到3f1c4e4b6b16bbbd69b2ee476dc4f83adocument.write(abc);2cacc6d41bbb37262a98f745aa00fbf0时,已经从apache断开。

楼上是正确的, 使用 AJAX 吧!!!

楼主可以根据ajax的这种方法来修改您自己的代码

其实,从客户端通过js取得数据,是可以通过某个事件驱动提交的,1种是ajax,另一种是在满足一定条件的时候触发提交,比如通过setTimeout,满足一定条件,触发submit提交。总之,能完成lz的需要。

In PHP, you can use session_status() or session_id() to check whether the session has started. 1) Use the session_status() function. If PHP_SESSION_ACTIVE is returned, the session has been started. 2) Use the session_id() function, if a non-empty string is returned, the session has been started. Both methods can effectively check the session state, and choosing which method to use depends on the PHP version and personal preferences.

Managing concurrent session access in PHP can be done by the following methods: 1. Use the database to store session data, 2. Use Redis or Memcached, 3. Implement a session locking strategy. These methods help ensure data consistency and improve concurrency performance.

Load balancing affects session management, but can be resolved with session replication, session stickiness, and centralized session storage. 1. Session Replication Copy session data between servers. 2. Session stickiness directs user requests to the same server. 3. Centralized session storage uses independent servers such as Redis to store session data to ensure data sharing.

Alternatives to PHP sessions include Cookies, Token-based Authentication, Database-based Sessions, and Redis/Memcached. 1.Cookies manage sessions by storing data on the client, which is simple but low in security. 2.Token-based Authentication uses tokens to verify users, which is highly secure but requires additional logic. 3.Database-basedSessions stores data in the database, which has good scalability but may affect performance. 4. Redis/Memcached uses distributed cache to improve performance and scalability, but requires additional matching

Sessionhijacking refers to an attacker impersonating a user by obtaining the user's sessionID. Prevention methods include: 1) encrypting communication using HTTPS; 2) verifying the source of the sessionID; 3) using a secure sessionID generation algorithm; 4) regularly updating the sessionID.
