這篇文章主要介紹了php使用socket編程的示例,大家參考使用吧
2個php測試文件 server.php 代碼如下: <?php //phpinfo(); //確保在連接客戶端時不會超時 set_time_limit(0); $ip = '127.0.0.1'; $port = 1935; /* +------------------------------- * @socket通信整個過程 +------------------------------- * @socket_create * @socket_bind * @socket_listen * @socket_accept * @socket_read * @socket_write * @socket_close +-------------------------------- */ /*---------------- 以下操作都是手冊上的 -------------------*/ if(($sock = socket_create(AF_INET,SOCK_STREAM,SOL_TCP)) < 0) { echo "socket_create() 失敗的原因是:".socket_strerror($sock)."n"; } if(($ret = socket_bind($sock,$ip,$port)) < 0) { echo "socket_bind() 失敗的原因是:".socket_strerror($ret)."n"; } if(($ret = socket_listen($sock,4)) < 0) { echo "socket_listen() 失敗的原因是:".socket_strerror($ret)."n"; } $count = 0; do { if (($msgsock = socket_accept($sock)) < 0) { echo "socket_accept() failed: reason: " . socket_strerror($msgsock) . "n"; break; } else { //發到客戶端 $msg ="測試成功!n"; socket_write($msgsock, $msg, strlen($msg)); echo "測試成功了啊n"; $buf = socket_read($msgsock,8192); $talkback = "收到的信息:$bufn"; echo $talkback; if(++$count >= 5){ break; }; } //echo $buf; socket_close($msgsock); } while (true); socket_close($sock); ?> client.php 代碼如下: <?php error_reporting(E_ALL); set_time_limit(0); echo "<h2>TCP/IP Connection</h2>n"; $port = 1935; $ip = "127.0.0.1"; /* +------------------------------- * @socket連接整個過程 +------------------------------- * @socket_create * @socket_connect * @socket_write * @socket_read * @socket_close +-------------------------------- */ $socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP); if ($socket < 0) { echo "socket_create() failed: reason: " . socket_strerror($socket) . "n"; }else { echo "OK.n"; } echo "試圖連接 '$ip' 端口 '$port'...n"; $result = socket_connect($socket, $ip, $port); if ($result < 0) { echo "socket_connect() failed.nReason: ($result) " . socket_strerror($result) . "n"; }else { echo "連接OKn"; } $in = "Horn"; $in .= "first bloodrn"; $out = ''; if(!socket_write($socket, $in, strlen($in))) { echo "socket_write() failed: reason: " . socket_strerror($socket) .
