php socket 超时时间,php socket如何设置超时

php socket设置超时的方法：首先如果【$waitAckSec=0】，则返回成功发送的字节；然后如果【$waitAckSec】大于0，则返回发送后接收到得内容；最后任何情况下，失败都返回FALSE。

php socket设置超时的方法：

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;
