Zoom to custom extent - PHP

[Kevin Grootendorst]

Basically, I'm trying to follow the GMAP example since they have a similar
feature - but trying to mimic the GMAP is way too complicated.
I'm giving up on this task - it's taking too long.

Thanks for your help.

Have you printed out the values  of $dfMinX, $dfMinY, $dfMaxX, $dfMaxY
to make shure
they arriwe correctly?
And the SetMapExtents function - I assume its your own function what is
the code of
this function doing?
