php socket超时设置的方法：首先打开相应的脚本文件；然后创建一个sendUdp方法；接着通过“socket_create”等方法对超时情况进行设置；最后保存该文件即可。

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; }
