php sockent通信
1.php服务端:server.php
<?php //确保在连接客户端时不会超时 set_time_limit(0); $ip = '127.0.0.1'; $port = 1935; /* +------------------------------- * @socket通信整个过程 +------------------------------- * @socket_create * @socket_bind * @socket_listen * @socket_accept * @socket_read * @socket_write * @socket_close +-------------------------------- */ /*---------------- 以下操作都是手册上的 -------------------*/ if(($sock = socket_create(AF_INET,SOCK_STREAM,SOL_TCP)) < 0) { echo "socket_create() 失败的原因是:".socket_strerror($sock)."\n"; } if(($ret = socket_bind($sock,$ip,$port)) < 0) { echo "socket_bind() 失败的原因是:".socket_strerror($ret)."\n"; } if(($ret = socket_listen($sock,4)) < 0) { echo "socket_listen() 失败的原因是:".socket_strerror($ret)."\n"; } $count = 0; do { if (($msgsock = socket_accept($sock)) < 0) { echo "socket_accept() failed: reason: " . socket_strerror($msgsock) . "\n"; break; } else { //发到客户端 $msg ="测试成功!\n"; socket_write($msgsock, $msg, strlen($msg)); echo "测试成功了啊\n"; $buf = socket_read($msgsock,8192); $talkback = "收到的信息:$buf\n"; echo $talkback; if(++$count >= 5){ break; }; } //echo $buf; socket_close($msgsock); } while (true); socket_close($sock); ?>
2.客户端:
client.php
<?php error_reporting(E_ALL); set_time_limit(0); echo "<h2>TCP/IP Connection</h2>\n"; $port = 1935; $ip = "127.0.0.1"; /* +------------------------------- * @socket连接整个过程 +------------------------------- * @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($socket) . "\n"; }else { echo "OK.\n"; } echo "试图连接 '$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 "连接OK\n"; } $in = "Ho\r\n"; $in .= "first blood\r\n"; $out = ''; if(!socket_write($socket, $in, strlen($in))) { echo "socket_write() failed: reason: " . socket_strerror($socket) . "\n"; }else { echo "发送到服务器信息成功!\n"; echo "发送的内容为:<font color='red'>$in</font> <br>"; } while($out = socket_read($socket, 8192)) { echo "接收服务器回传信息成功!\n"; echo "接受的内容为:",$out; } echo "关闭SOCKET...\n"; socket_close($socket); echo "关闭OK\n"; ?>
先在cmd下运行:php server.php文件,他会处于等待状态,
可以看到绑定的端口以及运行:
在cmd下运行: php client.php
