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 ''.-- Michael
