php socket服务端能不能在网页端开启？而不是只能用CLI模式开启
最近在做基于php socket的聊天程序，但是遇到了个问题：
开启ws端口只能在CMD下用php server.php的方式来开启端口，并不能关闭该CMD命令行窗口，一旦关闭就断开了socket连接。
请问，能不能做到不用这样的方式来开启ws服务端，而成为在网页端来开启？怎么做？
------解决方案--------------------
可以从网站上开启，但需要注意以下问题：
1、因为端口不能重复打开，所以你必须保证 server.php 只会被运行一次
2、web 方式下的 php 是超时设置有效的，当然你需要设置成永不超时
3、web 服务器是有超时限制的，虽然时间比较长。应用程序长时间无数据输出，将会被挂起或中断
4、如果 server.php 间歇的做标准输出的话，可以解决 3 的问题。但会引发下一个问题
5、php 在向标准输出写的时候，会检查到请求源的连接是否畅通。如果请求源被关闭了，就会终止程序的运行
当然也提供有阻止这一默认行为的方法

其实命令窗口的存在并不是什么坏事，至少他可以表示 ws 服务器正在工作
另外 ws 服务器在运行时，你应该要把重要的日志信息打印在窗口中，以便实时监视运行情况

How to calculate the total number of elements in a PHP multidimensional array?May 15, 2025 pm 09:00 PM

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.

What are the characteristics of do-while loops in PHP?May 15, 2025 pm 08:57 PM

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.

How to hash strings in PHP?May 15, 2025 pm 08:54 PM

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.

How to implement array sliding window in PHP?May 15, 2025 pm 08:51 PM

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.

How to use the __clone method in PHP?May 15, 2025 pm 08:48 PM

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.

How to use goto statements in PHP?May 15, 2025 pm 08:45 PM

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.

How to implement data statistics in PHP?May 15, 2025 pm 08:42 PM

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.

How to use anonymous functions in PHP?May 15, 2025 pm 08:39 PM

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.
