Problems with the Zoom Function of the PHP MapScript Module

[Assefa Yewondwossen]

Hi There,

 What I would suggest is to upgrade to 3.4 which is the current stable version of
mapserver. You could then patch the modifications done for the zooming in the 3.4
version. Fonctions affected are in php_mapscript.c:

  - DLEXPORT void php3_ms_map_zoomRectangle(INTERNAL_FUNCTION_PARAMETERS)
  - DLEXPORT void php3_ms_map_zoomPoint(INTERNAL_FUNCTION_PARAMETERS)

 In fact you can take the whole fonction and replace it and  it should work.


 As for the changes from 3.3.011 to 3.5, I am not aware of all the changes but there
are a lot of modifications happening (like integration of GDAL/OGR to support
diffrent vector and raster formats,  queries...). That's why I think you should go
with 3.4.
