I searched Mapserver site for UpdateFromString and found only MS RFC 31: 
Loading MapServer Objects from Strings. I was able to use the save 
function and print out the file which did work. However, my 2 attempts 
failed.

$map->UpdateFromString('saved_map.txt');  got Call to undefined method 
ms_map_obj::UpdateFromString()

 and

$map2 = msLoadMapFromString('saved_map.txt'); got Call to undefined 
function msLoadMapFromString()

I am using mapserver 5.0.0
