Hi,大家好,向各位朋友求助,我想实现以下需求:
系统登录的时候创建一个Socket长连接,在有效登录时间内,该Socket连接常驻内存,系统中所有页面都使用该Socket连接与远程服务端进行通信;
当登录过期,或者用户登出系统时,才关闭该连接。
我没搞错的话……PHP的变量在当次脚本执行结束之后,就都释放了,有没有什么办法能实现上面这个需求呢?
P.S 我现在使用的pfsockopen创建Socket连接,php官网对该函数的描述是:
This function behaves exactly as fsockopen() with the difference that the connection is not closed after the script finishes. It is the persistent version of fsockopen()
红字部分如何理解?这个函数能满足我当前的需求吗?
Thanks!

到目前为止,php 尚未提供 websock 服务功能
也就是说,你只能自己书写 cli 方式的服务器代码

额……新手表示这段【自己书写 cli 方式的服务器代码】不太明白,有空的时候还请详细解释一下,Thanks!
cli 方式 就是常说的 命令行方式
如果你连这个都不明白,那你是写不出来的
当然网上可以找到线程的服务器代码,不过你水品太低的话也是修改不了的

- - 额,可能我没描述清楚,CLI是知道的……
可否推荐一些开源的项目?我去参考一下,Thanks~~

楼主的cli方式可以实现
开源项目可以参考下 workerman ,专门做PHP服务器通讯的

Calculating the total number of elements in a PHP multidimensional array can be done using recursive or iterative methods. 1. The recursive method counts by traversing the array and recursively processing nested arrays. 2. The iterative method uses the stack to simulate recursion to avoid depth problems. 3. The array_walk_recursive function can also be implemented, but it requires manual counting.

In PHP, the characteristic of a do-while loop is to ensure that the loop body is executed at least once, and then decide whether to continue the loop based on the conditions. 1) It executes the loop body before conditional checking, suitable for scenarios where operations need to be performed at least once, such as user input verification and menu systems. 2) However, the syntax of the do-while loop can cause confusion among newbies and may add unnecessary performance overhead.

Efficient hashing strings in PHP can use the following methods: 1. Use the md5 function for fast hashing, but is not suitable for password storage. 2. Use the sha256 function to improve security. 3. Use the password_hash function to process passwords to provide the highest security and convenience.

Implementing an array sliding window in PHP can be done by functions slideWindow and slideWindowAverage. 1. Use the slideWindow function to split an array into a fixed-size subarray. 2. Use the slideWindowAverage function to calculate the average value in each window. 3. For real-time data streams, asynchronous processing and outlier detection can be used using ReactPHP.

The __clone method in PHP is used to perform custom operations when object cloning. When cloning an object using the clone keyword, if the object has a __clone method, the method will be automatically called, allowing customized processing during the cloning process, such as resetting the reference type attribute to ensure the independence of the cloned object.

In PHP, goto statements are used to unconditionally jump to specific tags in the program. 1) It can simplify the processing of complex nested loops or conditional statements, but 2) Using goto may make the code difficult to understand and maintain, and 3) It is recommended to give priority to the use of structured control statements. Overall, goto should be used with caution and best practices are followed to ensure the readability and maintainability of the code.

In PHP, data statistics can be achieved by using built-in functions, custom functions, and third-party libraries. 1) Use built-in functions such as array_sum() and count() to perform basic statistics. 2) Write custom functions to calculate complex statistics such as medians. 3) Use the PHP-ML library to perform advanced statistical analysis. Through these methods, data statistics can be performed efficiently.

Yes, anonymous functions in PHP refer to functions without names. They can be passed as parameters to other functions and as return values of functions, making the code more flexible and efficient. When using anonymous functions, you need to pay attention to scope and performance issues.
