[mapserver-users] proj module for php with pj_transform ?

[Arthur, John]

First question:

This may be a little off subject, but I have a Oracle database that stores
Latitude/Longitude in NAD27 UTM.  I would like to transform them to NAD83
Decimal on the fly for use in mapserver(and other things) using LCC
cordinates. The biggest issue is the conversion of NAD27->NAD83. Will this
be possible with pj_transform?

Second question:

Can I create a map layer with multiple points(point for each record) from a
database on the fly with php-mapscript? 


Thank you for your time.
