常用的google地图开发参数

phproogle：：apiKey
    .这是谷歌的用户API密钥。 .这也可以设置使用时，一个新的实例是instanciated构造。
phproogle::addGoogleMapControl() phproogle：：addGoogleMapControl（）
    此方法设置，如缩放控制控制器的谷歌地图，地图控制等此方法可以多次调用设置地图多个控件。 Options are:选项有：

        * GLargeMapControl GLargeMapControl
        * GSmallMapControl GSmallMapControl
        * GSmallZoomControl GSmallZoomControl
        * GScaleControl GScaleControl
        * GMapTypeControl GMapTypeControl
        * GHierarchicalMapTypeControl GHierarchicalMapTypeControl
        * GOverviewMapControl GOverviewMapControl

    addGoogleMapControl ( "GSmallMapControl" ); ?>
phproogle::mapType phproogle：：mapType
    This sets the map type to one of four options:这将设置地图类型的四个选项之一：

        * normal正常
        * satellite卫星
        * hybrid混合
        * physical物理

    mapType = "normal" ; ?>
phproogle::mapCenter phproogle：：mapCenter
    T这将设置分区范围内的地图中心。 该值是一个包含的纬度和经度的地图中心的顺序。
    $map->mapCenter = array(-33.862828, 151.216974); 1 $map->mapCenter = array(-33.862828, 151.216974); 1
phproogle::mapZoom phproogle：：mapZoom
    这将设置地图缩放级别。 零值是最广泛的缩放级别，并显示整个世界。 虽然19日是最高变焦，将显示建筑物。 Each zoom level doubles the zoom.每个缩放级别的两倍变焦。 12.默认值为12。
phproogle::addMarker() phproogle：：addMarker（）
    This function is used to create and place markers upon the map.这个函数用于创建和地点后，地图标记。 the addMarker method takes three args.在addMarker argS的方法有三个。

        * float $latitude浮动$纬度
        * float $longitude浮动$经度
        * string $html字符串$的HTML

    .经度和纬度都是数字值和HTML可以是任何HTML或文本将在标记球囊内。
phproogle::addMarkerAddress() phproogle：：addMarkerAddress（）
    此方法类似于phproogle：：addMarker（）和地方在地图上的标记。 然而，而不是接受经度和纬度来放置标志，这种方法需要两个值。

        * string $address字符串$地址
        * string $html字符串$的HTML

    参数的地址，如“二街宫人至法国巴黎简单的地址”。  balloon.在HTML参数再次，任何文本或HTML放置在信息气球。
phproogle::mapDivID phproogle：：mapDivID
    当设置，这将设置组ID的映射居住于默认值是“地图”
phproogle::mapWidth phproogle：：mapWidth
    顾名思义，这将设置div的宽度该地图居住于默认宽度为350像素。
phproogle::mapHeight phproogle：：mapHeight
    这将设置分区的高度该地图居住于默认值是300像素。
phproogle::googleJS() phproogle：：googleJS（）
    此方法返回的JavaScript字符串，用于在文件头，显示与谷歌API密钥连接字符串最频繁。
phproogle::drawMap() phproogle：：drawMap（）
   此方法返回的JavaScript制作完成的地图本身。
