Very nice. Lovely, readable, compact code. (Apart form all those horrible curly brackets.)

Yes - still lovely, readable, compact code. And dead simple to spot you've failed to indent the "else" section after "// where am i?". (Apart from all those horrible curly brackets.)

Uurgh -- curly brackets -- I see curly brackets -- and, aargh, horrible curly brackets -- eeew, and I think some code, maybe -- but definitely curly brackets.

Yep, nice -- still too many curly brackets, but readable.

Oh my god -- curly brackets and excessive indentation -- and curly brackets. Just a mo, where did I put my curly-brackets-and-whitespace-glasses? Aaaahhh, that's better!!
As you might have guessed, I *HATE* curly brackets with a vengeance, which is why I eschew both those styles and use PHP's alternative syntax:
if (...):
if (...):
// mmh
else:
// oh
endif;
while (...):
if (...):
// oh
else:
if (...):
// where am i?
else:
// huh!?
endif;
// hmm
endif;
if (...):
if (...):
// blah
endif;
// blah
endif;
// blah
endif;
Just beeeautiful! And, oh look, all the end tags tell me which kind of start tag they should match. And the compiler. Which leads to much more focussed error messages when you cock your structure up. I can't remeber the last time PHP told me I had a syntax arror at the end of the file -- if I've got unbalanced start/end tags, the error message usually points to a line in the middle of the file, slap bang in the target area.
OK, heretic advocacy over now. I'll just crawl back under my rock and kill a few more curly things...! ;)
Cheers!
