php - 如何从traceroute输出循环显示谷歌地图v3中的标记

Question

我是 php mysql 和 google maps v3 的新手。我在谷歌地图 v3 中遇到问题。我制作了基于网络的 traceroute 并将 traceroute 的结果映射到谷歌地图 v3 中，用于我的大学教育的最终项目。我尝试了很多教程，但没有奏效。我也尝试过这个论坛的教程，但没有任何效果。所以我的问题是我无法显示从数据库中获取位置数据的多个标记。也许是因为我是新手，不知道该怎么做。我也混淆了循环显示标记。所以这里是php代码：

<?php
error_reporting(E_ALL ^ (E_NOTICE));
ini_set('max_execution_time', 360);
$enable_log_user = FALSE;

global $ip, $host_name,  $host_ip, $output, $integer;

$host  = @$_POST['host']; 
$trace = @$_POST['trace'];
$self  = $_SERVER['PHP_SELF'];

include("phpsqlajax_dbinfo.php");
$connection = mysql_connect ('127.0.0.1', $username, $password);
if (!$connection) {  die('Not connected : ' . mysql_error());} 

$db_selected = mysql_select_db($database, $connection);
if (!$db_selected) {
  die ('Can\'t use db : ' . mysql_error());
} 

function get_ip()
{
    if (!empty($_SERVER['HTTP_CLIENT_IP']))   //check ip from share internet
    {
      $ip=$_SERVER['HTTP_CLIENT_IP'];
    }
    elseif (!empty($_SERVER['HTTP_X_FORWARDED_FOR']))   //to check ip is pass from proxy
    {
      $ip=$_SERVER['HTTP_X_FORWARDED_FOR'];
    }
    else
    {
      $ip=$_SERVER['REMOTE_ADDR'];
    }
    return $ip;
}

$ip = get_ip();

好吧，如果你们阅读我的代码，我真的很抱歉。看起来很乱。因为我不知道如何很好地显示代码。我想得到帮助的最重要的事情是在地图上。关于如何显示所有标记。尤其是循环。谷歌地图不显示标记。它只显示地图。因此，对于所有阅读此问题的大师。我只是需要你尽快的帮助。如果我的英语不好并且我对你们的错误，我真的很抱歉。

问题是你没有给你的标记任何位置：

 var point = [];
 var icon = pinImage;

 var marker = new google.maps.Marker({
    map: map,
    position: point,
    icon: pinImage,
    shadow: pinShadow
    });

所以你所做的就是将位置创建为一个空数组。您需要为该位置创建一个 LatLng() 。

所以现在你有一个点数组：

 var point = [new google.maps.LatLng(1.3667, 103.8000),new google.maps.LatLng(1.3667, 103.8000),new google.maps.LatLng(37.4192, -122.0574),new google.maps.LatLng(37.4192, -122.0574),new google.maps.LatLng(37.4192, -122.0574),new google.maps.LatLng(37.4192, -122.0574)];

 var icon = pinImage;

 var marker = new google.maps.Marker({
    map: map,
    position: point,
    icon: pinImage,
    shadow: pinShadow
    });

    marker.setMap(map);

您需要做的是遍历数组，为每个数组创建一个标记：

var point = [new google.maps.LatLng(1.3667, 103.8000),new google.maps.LatLng(1.3667, 103.8000),new google.maps.LatLng(37.4192, -122.0574),new google.maps.LatLng(37.4192, -122.0574),new google.maps.LatLng(37.4192, -122.0574),new google.maps.LatLng(37.4192, -122.0574)];

var icon = pinImage;

for (var i = 0; i < point.length; i++) {
     var marker = new google.maps.Marker({
        map: map,
        position: point[i],
        icon: pinImage,
        shadow: pinShadow
        });
}

setMap 行也是多余的，因为当您说 map:map 时，这就是您需要做的所有事情。
