Chris,

No I haven't saved a Mapscript object. Perhaps this is more a response 
to another post that said you could only access session variables, and 
not classes, from another page. However, you might try replacing

require('myclass.php');

with 

if(!extension_loaded('MapScript')){
	dl("php_mapscript.so");
}

There must be a way to persist a mapscript object, but I don't know enough of OO design to tell you the answer.

Jim
