PHP JSON 中文 编码
我用php把数组转成json格式传给jquery 时发现中文会变成奇怪的编码。于是在网上找了下解决方法,看到很多人用下面两个函数解决了:function arrayRecursive(&$array, $function, $apply_to_keys_also = false){ static $recursive_counter = 0; if (++$recursive_counter > 1000) { die('possible deep recursion attack'); } foreach ($array as $key => $value) { if (is_array($value)) { arrayRecursive($array[$key], $function, $apply_to_keys_also); } else { $array[$key] = $function($value); } if ($apply_to_keys_also && is_string($key)) { $new_key = $function($key); if ($new_key != $key) { $array[$new_key] = $array[$key]; unset($array[$key]); } } } $recursive_counter--;}
function JSON($array) { arrayRecursive($array, 'urlencode', true); $json = json_encode($array); return urldecode($json);}
我测试了下确实能解决问题,于是仔细研究了下代码,发现如下这句代码不知道是什么意思:
$array[$key] = $function($value);
我在这句话前后分别输出$array[$key]看下值,发现这句话把中文变成了一串编码。
求各位大侠解释下$function($value)是什么意思。

咳咳 你可以把‘$function’替换成传进去才参数$function的值再看
定义
function arrayRecursive(&$array, $function, $apply_to_keys_also = false) 中
$array[$key] = $function($value);
调用
arrayRecursive($array, ' urlencode', true);
所以 $array[$key] = $function($value);
就是 $array[$key] = urlencode($value);
呃。。好吧。。是传进来的参数。。我低端了……

这么看来这两个函数的作用就是先把数组中的每个值urlencode一下,然后json_encode转换成json格式,最后再把json格式的字符串urldecode。谢谢啦。真是看代码看得脑袋都转不过弯了
这个函数是针对 gbk 编码数据的
对于 utf-8 的数据,应该是不需要这样做的

Session in PHP is a mechanism for saving user data on the server side to maintain state between multiple requests. Specifically, 1) the session is started by the session_start() function, and data is stored and read through the $_SESSION super global array; 2) the session data is stored in the server's temporary files by default, but can be optimized through database or memory storage; 3) the session can be used to realize user login status tracking and shopping cart management functions; 4) Pay attention to the secure transmission and performance optimization of the session to ensure the security and efficiency of the application.

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.
