json_encode,汉字问题

本帖最后由 xtjsxtj 于 2015-04-09 21:50:26 编辑 按网上大部分说法是先将汉字urlencode,json_encode后再urldecode

这样,有个问题是,假如原来:
$arr = array ('a'=>urlencode('脚本,之家'));   //简体中文BGK编码
echo urldecode(json_encode($arr));

则结果为{"a": "脚本,之家"}
这是一个非法的json串,json_decode是解不开的

大家是如何这样解决这个问题的

是不是都转换成了utf8编码了

假如这个json串还要做url请求的参数,还要urlencode,这个又要怎样处理呢?
按utf8 先json_encode,然后再对整个json串做urlencode吗?
------解决思路----------------------
首先 gbk 的 {"a": "脚本,之家"} 并不是非法的 json 串
JSON 从来就没有要求过值域的字符集

至于不能被 json_decode 解开,是因为函数开发者认为 php 收到的 json 串都是由 XMLHttpRequest 发来的,而 XMLHttpRequest 总是以 utf-8 编码发送数据。因此就没有不要再在函数中辨别字符集了
从而造成 php 的 json 函数只支持 utf-8 的情况

既然已经这样了,那你就得去适应这个环境

How do you loop through all the values stored in a PHP session?How do you loop through all the values stored in a PHP session?Apr 26, 2025 am 12:06 AM

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.

What are some common problems that can cause PHP sessions to fail?What are some common problems that can cause PHP sessions to fail?Apr 25, 2025 am 12:16 AM

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.

How do you debug session-related issues in PHP?How do you debug session-related issues in PHP?Apr 25, 2025 am 12:12 AM

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.

What happens if session_start() is called multiple times?What happens if session_start() is called multiple times?Apr 25, 2025 am 12:06 AM

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.

How do you configure the session lifetime in PHP?How do you configure the session lifetime in PHP?Apr 25, 2025 am 12:05 AM

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.
