Thanks

I don't need to manipulate the array in the object just get its value.
I am trying to update some php 4.0.6 code that makes liberal use of
the Super Global "$GLOBALS" and eval() (perhaps there was no other way
in php 4.0.6) which I have updated to work with php 5.3 but would like
to rewrite the code completely to not make use of such an unsafe
method of passing variables around! Using a getter method seems to be
the best or better alternative.
