PHP页面跳转问题
共有两个问题
问题1:
在之间的PHP代码中如何获得date的值。
问题2:
在PHP页面中,能够实现两个页面间传值但是页面不跳转?我就是想把问题1中的date值传到另一个PHP文件,但是当前页面不能跳转。
刚接触PHP不久,很多东西都不会,希望朋友们帮帮忙,不要简单的说用AJAX什么的,好心人能否直接上代码?看着简单明了,谢谢
------解决方案--------------------
1: 通过ajax请求php传值。或者表单提交传值
2:session/cookie
------解决方案--------------------
1.
ajax 当然简单点可以用jquery 封装好的 get post 到php的处理页面
2.像乔丹说的 全局变量 $_SESSION['xxx'] 或者直接 include 包含页面,当然你还能蛋痛的输出html js 再来个ajax...
或者...
memcache...

- HTML code
#Ajax: $.ajax({ type: "POST", url: "some.php", data: "name=John&location=Boston", success: function(msg){ alert( "Data Saved: " + msg ); } }); <div class="clear"> </div>

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.

The session realizes user authentication through the server-side state management mechanism. 1) Session creation and generation of unique IDs, 2) IDs are passed through cookies, 3) Server stores and accesses session data through IDs, 4) User authentication and status management are realized, improving application security and user experience.

Reasons for PHPSession failure include configuration errors, cookie issues, and session expiration. 1. Configuration error: Check and set the correct session.save_path. 2.Cookie problem: Make sure the cookie is set correctly. 3.Session expires: Adjust session.gc_maxlifetime value to extend session time.

Methods to debug session problems in PHP include: 1. Check whether the session is started correctly; 2. Verify the delivery of the session ID; 3. Check the storage and reading of session data; 4. Check the server configuration. By outputting session ID and data, viewing session file content, etc., you can effectively diagnose and solve session-related problems.

Multiple calls to session_start() will result in warning messages and possible data overwrites. 1) PHP will issue a warning, prompting that the session has been started. 2) It may cause unexpected overwriting of session data. 3) Use session_status() to check the session status to avoid repeated calls.

Configuring the session lifecycle in PHP can be achieved by setting session.gc_maxlifetime and session.cookie_lifetime. 1) session.gc_maxlifetime controls the survival time of server-side session data, 2) session.cookie_lifetime controls the life cycle of client cookies. When set to 0, the cookie expires when the browser is closed.
