我正在嘗試創建一個簡單的客戶端/服務器應用程序，因此我正在嘗試使用PHP中的套接字。現在我在C＃中有一個簡單的客戶端，它很好地連接到服務器，但我只能連接一個客戶端到這個服務器（我發現這個代碼示例在線，併爲測試目的調整了一下）。PHP套接字 - 接受多個連接
搞笑的是我發現了同樣的問題，基於同樣的例子在這裏：https://stackoverflow.com/questions/10318023/php-socket-connections-cant-handle-multiple-connection
我試圖瞭解它的每一個部分，我靠近看到它是如何工作的詳細，但由於某些原因，當我連接第二個客戶端時，第一個客戶端會斷開連接/崩潰。
任何人都可以給我一些狂野的想法或指向我應該看的地方嗎？
