TRUE or true?

Hi all, I know from a code point of view it makes no difference at all (i.e. they both work), but which format do you all use for booleans? TRUE / FALSE or true / false The PHP manual uses both :) Zend Studio tries to auto-complete to the lower-case variant. I'm not seeking a big debate on this, more of an overall poll-count (and any sound arguments for A vs. B, or should I say T vs. t) -- Best regards, Richard Davey http://www.phpcommunity.org/wiki/296.html
