[mapserver-users] $_SESSION variable substitution

[Stephen Woodbridge]

The short answer is no.

The longer answer is $_SESSION is a php variable and it only exist while 
php is executing. When you call mapserver cgi, it is not running in the 
php environment. and if you use it in a template, there is not for 
mapserver to tell the webserver that it needs to run php processor over 
the results of the out of mapserver, ie. the processed template.

If you really need to do this you might be able convert the info you 
need into cookie or change you mapserver request to include the info you 
need on its url than then use url substitution.

Or you might develop you application in php/mapscript where it will run 
in the php environment.

It might help more to explain why you think you need to do this, and 
people might be able to offer other ways to do something similar.
