1.3.0

下載

phpgpx

用PHP編寫的簡單庫，用於閱讀和創建GPX文件。可以使用Jekyll生成的GitHub頁面獲得文檔。

歡迎貢獻和反饋！請檢查托多的問題。我會很高興的每個功能或拉請求。

存儲庫分支：

master ：最新穩定版本
develop ：在2.x上工作

特徵

全面支持官方規範。
統計計算。
擴展。
JSON＆XML和PHP數組輸出。

支持的擴展

Garmin TrackPointExtension：http：//www.garmin.com/xmlschemas/trackpointextension/v1

統計計算

（平滑）距離（M）
平均速度（m/s）
平均速度（S/km）
最小 /最大高度（M）
最小 /最大坐標（[[LAT，LNG]）
（平滑）高程增益 /損失（M）
開始 /結束（DateTime對象）
開始 /結束坐標（[[LAT，LNG]）
持續時間（秒）

安裝

您可以輕鬆地使用Composer安裝PHPGPX庫。目前還沒有穩定的發布，因此請使用釋放候選者。

 composer require sibyx/phpgpx:1.3.0

例子

打開GPX文件並加載基本統計數據

 <?php
use phpGPX  phpGPX ;

$ gpx = new phpGPX ();
	
$ file = $ gpx -> load ( ' example.gpx ' );
	
foreach ( $ file -> tracks as $ track )
{
    // Statistics for whole track
    $ track -> stats -> toArray ();
    
    foreach ( $ track -> segments as $ segment )
    {
    	// Statistics for segment of track
    	$ segment -> stats -> toArray ();
    }
}

寫入文件

 <?php
use phpGPX  phpGPX ;

$ gpx = new phpGPX ();
	
$ file = $ gpx -> load ( ' example.gpx ' );

// XML
$ file -> save ( ' output.gpx ' , phpGPX:: XML_FORMAT );
	
//JSON
$ file -> save ( ' output.json ' , phpGPX:: JSON_FORMAT );

從頭開始創建文件

 <?php
