我有一個SDO_GEOMETRY格式的Oracle圖層，我想在Web地圖應用程序中顯示。我已經發現了Oracle Spatial開發人員指南（http://docs.oracle.com/cd/B28359_01/appdev.111/b28400/sdo_util.htm#BJEFIFEF）在這個例子中：如何將Oracle SDO_GEOMETRY轉換爲PHP中的KML或JSON
-- Convert cola_c geometry to a KML document; convert that result to
-- a spatial geometry.
DECLARE
kmlgeom CLOB;
val_result VARCHAR2(5);
geom_result SDO_GEOMETRY;
geom SDO_GEOMETRY;
BEGIN
SELECT c.shape INTO geom FROM cola_markets c WHERE c.name = 'cola_c';
-- To KML geometry
kmlgeom := SDO_UTIL.TO_KMLGEOMETRY(geom);
DBMS_OUTPUT.PUT_LINE('To KML geometry result = ' || TO_CHAR(kmlgeom));
-- From KML geometry
geom_result := SDO_UTIL.FROM_KMLGEOMETRY(kmlgeom);
-- Validate the returned geometry
val_result := SDO_GEOM.VALIDATE_GEOMETRY_WITH_CONTEXT(geom_result, 0.005);
DBMS_OUTPUT.PUT_LINE('Validation result = ' || val_result);
END;
/
To KML geometry result =
<Polygon><extrude>0</extrude><tessellate>0</tessellate><altitudeMode>relativeToG
round</altitudeMode><outerBoundaryIs><LinearRing><coordinates>3.0,3.0 6.0,3.0
6.0,5.0 4.0,5.0 3.0,3.0 </coordinates></LinearRing></outerBoundaryIs></Polygon>
Validation result = TRUE
是否有可能使用SDO_UTIL.TO.KMLGEOMETRY在PHP？
或者有沒有其他的方法可以在網絡地圖應用中使用SDO_GEOMETRY？
