Hi Dash,
Yup here's the function cal and the function:
if (projectLatLon($lat,$lon))
{
...do stuff
}
else
{
..do other stuff
}
function projectLatLon($lat,$lon)
{
GLOBAL $lccXY;
$dlat = doubleval($lat);
$dlon = doubleval($lon);
//project from geodetic coordinate degrees
$parms1[0] = "proj=longlat";
$parms1[1] = "ellps=GRS80";
$parms1[2] = "datum=NAD83";
$parms1[3] = "no_defs";
$projLonLat = pj_init($parms1);
//project to lambert conical x,y
$parms2[0] = "proj=lcc";
$parms2[1] = "ellps=GRS80";
$parms2[2] = "datum=NAD83";
$parms2[3] = "lat_0= 49.0";
$parms2[4] = "lon_0= -95.0";
$parms2[5] = "lat_1= 49.0";
$parms2[6] = "lat_2= 77.0";
$parms2[7] = "units=m";
$projLCC = pj_init($parms2);
$lccXY = pj_transform($projLonLat, $projLCC, $dlon, $dlat,0 );
if ($lccXY == 0)
{
pj_free($pj);
return FALSE;
}
else
{
pj_free($pj);
return TRUE;
}
}
thx,
Paul

Do you have an example of the function (or requirements) you need to pass
along? I've got lots of functions I use in multiple files that call one
include file. Works just fine.
Unfortunately, I have almost no experience with PHP Classes. I need to
learn, but I have not yet had a chance to split my mind apart and learn
the concepts behind it. It does not help that PHP's OO stuff is a little
bit weak compared to other languages (from what I have heard).
