PHP MapScript zoomscale optional parameter

[Julien-Samuel Lacroix]

Hi,

Simply don't specify the optional parameter is correct. There's a 
parameter missing in the documentation.

void zoomscale(double nScale, pointObj oPixelPos, int nImageWidth,
                   int nImageHeight, rectObj oGeorefExt,
                   [rectObj oMaxGeorefExt])

So your problem here is that one parameter is missing:
The fifth parameter (oGeorefExt) is mandatory and the sixth 
(oMaxGeorefExt) is optional.
