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;
}以上是php socket 超时设置的方法的详细内容。更多信息请关注PHP中文网其他相关文章！
