假设您希望我们将sietID作为信息

$ export CFLAGS=\""-I/usr/lib/..."\"  # escaped double quotes make them to be included in the string.
$ make

然后在你的var弹出窗口中你应该添加信息文本

            var features = [
          <?php
            global $wpdb;
              $prependStr ="";
              foreach( $wpdb->get_results("SELECT siteID, latitude, longitude FROM site_coordinates2", OBJECT) as $key => $row) {
                 $latitude = $row->latitude;
                 $longitude = $row->longitude;
                 $info = $row->siteID;
             echo $prependStr;
         ?>
  {
      position: new google.maps.LatLng(<?php echo $latitude; ?>, <?php echo $longitude; ?>),
      info:<?php echo $info;?>,

  }
  <?php
  $prependStr =",";
  }
  ?>
          ];
