Hi. I just wanted to quickly see if PHP supported ranges in its switch/case statement (http://en.wikipedia.org/wiki/Ellipsis) <?php $s = intval(date('s')); switch($s) { case 0...9 : echo 'Between 0 and 9'; break; case 10...19 : echo 'Between 10 and 19'; break; case 20...29 : echo 'Between 20 and 29'; break; case 30...39 : echo 'Between 30 and 39'; break; case 40...49 : echo 'Between 40 and 49'; break; case 50...59 : echo 'Between 50 and 59'; break; default : echo 'Unknown : ', $s; } ?> Completely unexpectedly, the above code runs but produces the wrong output. Interestingly, altering the number of dots and adding spaces all result in parse errors ... case 0..9 : // 2 dots, no spaces case 0 .. 9 : // 2 dots, with spaces case 0 ... 9 : // 3 dots, with spaces It was confusing that the initial code ran without a parse error, but considering that it did, it would suggest that the case values are actually meaningful in some way. php -r "var_dump(10...19);" Interesting output ... string(6) "100.19" And that took me a little while to work out. It's all to do with PHP's type juggling. 10...19 What I'm not sure is why the middle empty string is output as 0. "10" . . ".19" becomes "10" . "0" . ".19" which becomes "100.19" Oddly, more . don't work. php -r "var_dump(10....19);" all result in parse errors. I don't know if this is a "bug" per se, but it is an oddity that I though I'd share. And what is even more surprising is that the initial code works in the PHP V4.0.0. So maybe an 11 years old bug. You really would have thought I'd have more to do with my time!
