百度地圖分佈圖（百度地圖api司機位置實時定位分佈圖）

就類似於我們使用共享單車app的時候，可以看到我們周圍的空閒單車分佈。e代駕 在後臺管理系統需求裡也有此功能，目的是為了實時看到目標城市下的所有司機狀態。
一、controller
//controller file //$drivers 是拿到當前城市所有的司機資訊 foreach($drivers as $driver) { $driver_phone=$driver['phone']; $last_latitude=$driver->position->baidu_lat;$last_longitude=$driver->position->baidu_lng; $last_phone=$driver['phone']; $last_name=$driver['name']; $driver_name=$driver['user']; //極速查勘的司機 空閒-藍 2 忙碌-紫 4 $_iStatusJiSuChaKan = $this->getDriverStatusJiSuChaKan($driver['user'],$_iStatus); if(!empty($_iStatusJiSuChaKan)){ $_iStatus = $_iStatusJiSuChaKan; } $addPoint.=sprintf('marker = addDriver(%s, %s, "%s",%s);'."\n", $last_latitude, $last_longitude, $driver_name, $_iStatus); }$data['list']=$addPoint; //然後把$data丟給view
//print_r($data); Array ( [city] => 北京 [addPoint] => marker = addDriver(32.059339, 118.787148, "BJ9010",0); marker = addDriver(40.018634, 116.479259, "BJ9017",0); marker = addDriver(39.855547, 116.504390, "BJ5780",0); marker = addDriver(40.019712, 116.472373, "BJ6162",0); marker = addDriver(39.898936, 116.518997, "BJ6792",0); marker = addDriver(39.876989, 116.481366, "BJ9031",1); marker = addDriver(39.951750, 116.520674, "BJ6900",0); marker = addDriver(39.852491, 116.281912, "BJ7063",0); marker = addDriver(39.981293, 116.522406, "BJ7185",0); marker = addDriver(39.986936, 116.322063, "BJ7516",0); )
