使用php创建WebSocket服务

执行方法:
首先先修改server.php与index.html的ip
通过命令行执行 [php路径]php.exe "[文件路径]server.php"
然后通过浏览器打开index.html

<?include 'websocket.class.php';$config=array('address'=>'192.168.0.200','port'=>'8000','event'=>'WSevent',//回调函数的函数名'log'=>true,);$websocket = new websocket($config);$websocket->run();function WSevent($type,$event){ global $websocket;if('in'==$type){$websocket->log('客户进入id:'.$event['k']);}elseif('out'==$type){$websocket->log('客户退出id:'.$event['k']);}elseif('msg'==$type){$websocket->log($event['k'].'消息:'.$event['msg']);roboot($event['sign'],$event['msg']);}}function roboot($sign,$t){ global $websocket; switch ($t){ case 'hello': $show='hello,GIt @ OSC';break; case 'name':$show='Robot';break; case 'time': $show='当前时间:'.date('Y-m-d H:i:s');break; case '再见': $show='( ^_^ )/~~拜拜';$websocket->write($sign,'Robot:'.$show);$websocket->close($sign);return;break; case '天王盖地虎': $array = array('小鸡炖蘑菇','宝塔震河妖','粒粒皆辛苦'); $show = $array[rand(0,2)];break;default: $show='( ⊙o⊙?)不懂,你可以尝试说:hello,name,time,再见,天王盖地虎.';}$websocket->write($sign,'Robot:'.$show);}?>
