php socket超時設(shè)置的方法：首先打開相應(yīng)的腳本文件；然后創(chuàng)建一個sendUdp方法；接著通過“socket_create”等方法對超時情況進行設(shè)置；最后保存該文件即可。

php socket 超時設(shè)置

1、php創(chuàng)建socket的方法和設(shè)置超時的方法，貼出來分享一下

//如果$waitAckSec=0，則返回成功發(fā)送的字節(jié)??
    //如果$waitAckSec大于0，則返回發(fā)送后接收到得內(nèi)容
    //任何情況下，失敗都返回FALSE
    function sendUdp($host, $port, $buff,$waitAckSec=0) {
        $socket = ($result = @socket_create(AF_INET,SOCK_DGRAM,SOL_UDP));
        //發(fā)送超時1秒
        socket_set_option($socket,SOL_SOCKET,SO_RCVTIMEO,array("sec"=>3, "usec"=>0 ) );
        //接收超時6秒
        socket_set_option($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 = "";

 $result_temp = phpext_unpack($result_temp);
 $this->sendUdp($host, $port, $result_temp["ackdata"]);
 $list = array_merge($list,$result_temp['data']['list']);
                            }
                            $result['data']['list'] = $list;

 }
 $result['data']['list'] = $list;
                            }
                        }
