regex everything in between html comments

Question

i am trying to remove everything in between html comments  in php using regex. can anyone lend a hand please

$str = preg_replace('/\<!--.*\-->/', '', $str);

You will need to look for `\n` also since comments can be multiline. — prajeesh kumar, May 10 '12 at 03:23
Don't use regexes on html. Every time you do, Alan Turing kills a kitten: http://stackoverflow.com/a/1732454/118068 — Marc B, May 10 '12 at 03:23
@prajeesh, and also use non-greedy matches, since there can be multiple comments in a single file. e.g. this is why regexes are a bad idea — Marc B, May 10 '12 at 03:23
It’s unclear whether you want to produce an empty string or `` after your replace operation. — Benji XVI, Jun 12 '15 at 14:36

Try preg_replace('//sU', '', $str);

-1, How this could match ``... some text ...``? Might be a better solution would be to use ``non-greedy`` parameter. – Cylian May 10 '12 at 04:22
@Cylian, `some text` is not in an html comment. So it's not supposed to match. By the way, it's already using `non-greedy` matching – Rob May 10 '12 at 04:25
@Rob:Point to notice here that, OP here wants to remove the data between comments. So, isn't that case, ``some text`` will get removed? – Cylian May 10 '12 at 04:27
The question is very confusingly worded, "in between comments" suggests just that – remove *everything between* (multiple) comments. Editing for clarity. – Benji XVI Jun 12 '15 at 14:32
