quick basic question, hopefully not dumb

Posted on 16th Feb 2014 07:03 pm by admin

I don't know how to search for this, so forgive me if it's been covered...

I often see an example like this:
$a = $b . " " . $c; // concatenate strings with space

I'm wondering if there is something wrong with this method:
$a = "$b $c";

I can see that maybe the 1st method is more clear as to intention, but I'm not sure if it's really worth the extra trouble. What do you guys think?

Thanks,
