It seems that the updateFromString() methods were never implemented in 
PHP MapScript. We'll try to work on that soon and get them in 5.4. Here 
is the related ticket:
   http://trac.osgeo.org/mapserver/ticket/2298

Note that there is no updateFromString() on the mapObj, only on the 
individual object classes that compose a map (layerObj, classObj, etc.). 
To instantiate a map from a saved file, you can pass the path to the 
saved mapfile the mapObj constructor itself.

Actually, here is a list of the classes that implement 
updateFromString(), from a quick grep of the SWIG MapScript code:

class.i:    int updateFromString(char *snippet)
label.i:  int updateFromString(char *snippet)
layer.i:    int updateFromString(char *snippet)
legend.i:  int updateFromString(char *snippet)
querymap.i:  int updateFromString(char *snippet)
referencemap.i:  int updateFromString(char *snippet)
scalebar.i:  int updateFromString(char *snippet)
style.i:    int updateFromString(char *snippet)
web.i:    int updateFromString(char *snippet)
