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,
