Multiline regular expressions... is it best just to use the s modifier? For example, if I wanted to remove all PHP style comments from a file (no, I'm not trying to make a compression function like Kalle's, just playing around with different methods of templating), I'm currently using;

~/\*.*?\*/~s

What about without the s? I got this to work:

~/\*(.*?\r?\n?)+?\*/~

Can you think of a more efficient way?
