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.
