On my server, version A without {} produces errors when the script runs:

Parse error: parse error, unexpected T_ENCAPSED_AND_WHITESPACE, 
expecting T_STRING or T_VARIABLE or T_NUM_STRING in 
(home/filepath/filename.php) on line 45

To confirm, Version A is when the var is inside a double quoted string, 
with single quotes around the array['varname']

Interesting.  I hadn't seen mention of that in my books.  It's just 
further confirmation that I need more books!  =)
