php socket 超时设置
1、php创建socket的方法和设置超时的方法，贴出来分享一下
//如果$waitacksec=0，则返回成功发送的字节 //如果$waitacksec大于0，则返回发送后接收到得内容 //任何情况下，失败都返回false function sendudp($host, $port, $buff,$waitacksec=0) { $socket = ($result = @socket_create(af_inet,sock_dgram,sol_udp)); //发送超时1秒 socket_set_option($socket,sol_socket,so_rcvtimeo,array("sec"=>3, "usec"=>0 ) ); //接收超时6秒 socket_set_option($socket,sol_socket,so_sndtimeo,array("sec"=>6, "usec"=>0 ) ); if($socket){ $result = @socket_sendto($socket,$buff,strlen($buff),0,$host,$port); if($waitacksec>0){ $result = false; $read = array($socket); $write = null; $except = null; if(@socket_select($read,$write,$except,$waitacksec)>0){ $fromhost = ""; $fromport = 0; @socket_recvfrom($socket,$result,4096,0,$fromhost,$fromport); $result = phpext_unpack($result); if($result["needack"] == 1){ $this->sendudp($host, $port, $result["ackdata"]); if(isset ($result['data']['list']) && isset ($result['data']['totalcount'])){ $list = $result['data']['list']; $count = $result['data']['totalcount']; while($count> count($list)){ @socket_recvfrom($socket,$result_temp,4096,0,$fromhost,$fromport); $result_temp = phpext_unpack($result_temp); $this->sendudp($host, $port, $result_temp["ackdata"]); $list = array_merge($list,$result_temp['data']['list']); } $result['data']['list'] = $list; } }else{ @socket_recvfrom($socket,$result,4096,0,$fromhost,$fromport); $result = phpext_unpack($result); if($result["needack"] == 1){ $this->sendudp($host, $port, $result["ackdata"]); if(isset ($result['data']['result']) && isset ($result['data']['userid'])){ $list = $result['data']['list']; $count = $result['data']['totalcount']; while($count> count($list)){ @socket_recvfrom($socket,$result_temp,4096,0,$fromhost,$fromport); $result_temp = phpext_unpack($result_temp); $this->sendudp($host, $port, $result_temp["ackdata"]); $list = array_merge($list,$result_temp['data']['list']); } $result['data']['list'] = $list; } } } }else{ $result = send_udp_error; } } @socket_close($socket); } return $result; }
