Ah, MapScript object persistence... the restless leg syndrome of
MapServer. Though neither convenient nor pretty, the One True Way (TM)
to persist MapScript objects is the mapfile format. Every other
approach will just cause hair loss, unexplained rashes, nausea, and
memory leakage.
The UpdateFromString and save methods are the way to go. Your target
MapScript language has no problem persisting strings, and you don't
have to worry about the mess of object lifetimes that might result
from trying to light up a once dead mapObj.

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
