[TOC] ## 函數 ``` stream_?socket_?accept stream_?socket_?client stream_?socket_?enable_?crypto stream_?socket_?get_?name 獲取本地或者遠程的套接字名稱 stream_?socket_?pair stream_?socket_?recvfrom stream_?socket_?sendto stream_?socket_?server stream_?socket_?shutdown stream_set_blocking 為資源流設置阻塞或者阻塞模式 stream_set_timeout 設置超時時間 ``` ## 實例 ## 創建socket 服務 ``` $socket = stream_socket_server("0.0.0.0:9090",$errno,$errstr); if (!$socket){ echo "$errstr ($errno)<br />\n"; die(); } while($client = stream_socket_accept($socket,60)){ print_r(stream_socket_get_name($client,true)); // 也可使用 fread 與fwrtie while ($msg = @stream_socket_recvfrom($client,1024)){ print_r($msg."\n"); stream_socket_sendto($client,"to:".$msg); fclose($client); } } ``` ### 模擬socket客戶端 ``` $fp = stream_socket_client("tcp://localhost:8010", $errno, $errstr, 30); if (!$fp) { echo "$errstr ($errno)<br />\n"; } else { fwrite($fp, "GET / HTTP/1.0\r\nHost: localhost\r\nAccept: */*\r\n\r\n"); while (!feof($fp)) { echo fgets($fp, 1024); } fclose($fp); } ```
