urlencode的问题奇怪了，请教大家
我想把字符串“('baidu')中”用php的urlencode函数输出这样的字符串：('baidu')%e4%b8%ad
但实际上输出：%28%27baidu%27%29，
我在百度搜索关键字：在线url编码,结果排名第三的是：百度应用的一个url编码小程序，在那个用utf8编码就可以输出：
('baidu')%e4%b8%ad，请问为什么啊？
当然字符串当中汉字“中”，生成的不一样无所谓，因为我的源代码是utf8,的，所以，但是我就奇怪了怎么才能让php
的urlencode()函数，不编码逗号和小括号呢？
------解决方案--------------------
string urlencode ( string $str )
返回字符串，此字符串中除了 -_. 之外的所有非字母数字字符都将被替换成百分号（%）后跟两位十六进制数，空格则编码为加号（+）。
百度那个并不严格，如果你不希望转码括号，可以对转码后的结果用 str_replace('%28', '(', $enstr) 替换过来
------解决方案--------------------
百度那个就是不准,我用过.

Give an example of storing an array in a PHP session.Apr 27, 2025 am 12:20 AMArrays can be stored in PHP sessions. 1. Start the session and use session_start(). 2. Create an array and store it in $_SESSION. 3. Retrieve the array through $_SESSION. 4. Optimize session data to improve performance.
How does garbage collection work for PHP sessions?Apr 27, 2025 am 12:19 AMPHP session garbage collection is triggered through a probability mechanism to clean up expired session data. 1) Set the trigger probability and session life cycle in the configuration file; 2) You can use cron tasks to optimize high-load applications; 3) You need to balance the garbage collection frequency and performance to avoid data loss.
How can you trace session activity in PHP?Apr 27, 2025 am 12:10 AMTracking user session activities in PHP is implemented through session management. 1) Use session_start() to start the session. 2) Store and access data through the $_SESSION array. 3) Call session_destroy() to end the session.

How do you loop through all the values stored in a PHP session?Apr 26, 2025 am 12:06 AMIn 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.
Explain how to use sessions for user authentication.Apr 26, 2025 am 12:04 AMThe 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.
