php socket如何發送

如果我要寫發給用戶端 send 第一個參數怎麼寫

回複討論(解決方案)

$client = socket_accept($this->master);//27行

36 行的 $bytes = @socket_recv($socket,$buffer,2048,0); 是接收用戶端發送的資料
47 當的 $this->send($socket, $buffer); 是向用戶端發送資料

這是一個測試程式，只是原樣發回用戶端發送的資料。離實用還遠呢
你需要寫一個程式，分析處理使用者發送的資料
依據處理的結果，返回相應的資料
這段程式要在 46、47 行之間調用

有沒有實用點得代碼 我找了1天了 沒看到靠譜的 各種問題 只要 用戶端發送a 然後服務端接收到資料 如果是a 那就原樣返回a

你的這個程式不就是這樣的嗎？

問題是你的用戶端

你的這個程式不就是這樣的嗎？

問題是你的用戶端

用戶端我用c++寫 寫好的 我現在在寫服務端

那你下載一個 《Android和PHP開發最佳實務》源碼. 下載頻道就有
都出書了，應該沒有問題了吧。
