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

<?php $map -> 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

<?php $map -> 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.
