Hi all,
I'm a C newbie and just started experimenting with the PHP internals
a couple weeks ago... A few days ago I noticed assignment/comparison
of char variables to '' (nothing between single quotes) in, for
example, the is_numeric_string function (zend_operators.h),
snprintf.c, spprintf.c, etc. I don't understand what it's doing. :-/
I don't see what you're seeing and cannot find a single occurrence of ''.

I think he is talking about this, it appears as '' on lxr
