常用的google地圖開發參數
phproogle：：apiKey
.這是谷歌的用戶API密鑰。 .這也可以設置使用時，一個新的實例是instanciated構造。
phproogle::addGoogleMapControl() phproogle：：addGoogleMapControl（）
此方法設置，如縮放控制控制器的谷歌地圖，地圖控制等此方法可以多次調用設置地圖多個控件。 Options are:選項有：
* 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:這將設置地圖類型的四個選項之一：
* normal正常
* satellite衛星
* hybrid混合
* physical物理
<?php $map -> mapType = "normal" ; ?>
phproogle::mapCenter phproogle：：mapCenter
T這將設置分區范圍內的地圖中心。 該值是一個包含的緯度和經度的地圖中心的順序。
$map->mapCenter = array(-33.862828, 151.216974); 1 $map->mapCenter = array(-33.862828, 151.216974); 1
phproogle::mapZoom phproogle：：mapZoom
這將設置地圖縮放級別。 零值是最廣泛的縮放級別，並顯示整個世界。 雖然19日是最高變焦，將顯示建築物。 Each zoom level doubles the zoom.每個縮放級別的兩倍變焦。 12.默認值為12。
phproogle::addMarker() phproogle：：addMarker（）
This function is used to create and place markers upon the map.這個函數用於創建和地點後，地圖標記。 the addMarker method takes three args.在addMarker argS的方法有三個。
* float $latitude浮動$緯度
* float $longitude浮動$經度
* string $html字符串$的HTML
.經度和緯度都是數字值和HTML可以是任何HTML或文本將在標記球囊內。
phproogle::addMarkerAddress() phproogle：：addMarkerAddress（）
此方法類似於phproogle：：addMarker（）和地方在地圖上的標記。 然而，而不是接受經度和緯度來放置標志，這種方法需要兩個值。
* string $address字符串$地址
* string $html字符串$的HTML
參數的地址，如“二街宮人至法國巴黎簡單的地址”。 balloon.在HTML參數再次，任何文本或HTML放置在信息氣球。
phproogle::mapDivID phproogle：：mapDivID
當設置，這將設置組ID的映射居住於默認值是“地圖”
phproogle::mapWidth phproogle：：mapWidth
顧名思義，這將設置div的寬度該地圖居住於默認寬度為350像素。
phproogle::mapHeight phproogle：：mapHeight
這將設置分區的高度該地圖居住於默認值是300像素。
phproogle::googleJS() phproogle：：googleJS（）
此方法返回的JavaScript字符串，用於在文件頭，顯示與谷歌API密鑰連接字符串最頻繁。
phproogle::drawMap() phproogle：：drawMap（）
此方法返回的JavaScript制作完成的地圖本身。
