php and PROJ

[Chad Streck]

Thanks everyone for the help in getting our demo up and running.  Its 
looking like we may be getting this job, which means that for a point 
file, I'll have to be dynamically creating lat/long points on the map 
that is projected in AZ-C.  I plan on placing the points on a blank 
geographic projected layer which will place the points in the correct 
position, but I'll need to be able to get the world coordinates of a 
click on the image in lat/long and not AZ-C.  Is there an easy way to do 
this with php_mapscript or a way to access the PROJ library directly 
from PHP other than system/exec?

Thanks,
Chad Streck
