[TYPO3-dev] how to call php method from TS

[Vahan Amirbekyan]

folks is it possible to call some php method from TS?
I want my TS constants to be returned and somehow set up by PHP code and 
then to be used by TS script.

example....
you know this familiar condition for language selection
[globalVar = GP:L=1]
  	config.sys_language_uid = 1
	someconstant = somevalue
[GLOBAL]

imagine that I have 100 similar conditions values for which are stored 
in DB.
can i call PHP code that would set up the "someconstant" for be above?
