The curly braces are superfluous here, since you are using double quotes. I'm
not sure if you like having them there, but I think that less syntax yields a
simpler and cleaner appearance.
Yes, they are superfluous in this example, but not because we're in double quotes. You can ONLY use complex strings inside double quotes, AFAIK:
<?
$str = "blah";
echo "{$str}<br />"; // echos blah<br />
echo '{$str}<br />'; // echos {$str}<br />
?>As I'm sure you're aware, the use of the {braces} is to allow complex combinations of variables, like found in the manual http://www.php.net/types.string
In the above example, they are indeed not needed, but I've gotten into the habbit of using them on all strings for a few reasons;
- the fact that there can be no confusion (either human or PHP) over what I mean
- PHP will be non-greedy when looking for the valid variable name
- since i'm now in the habbit, I never have to debug examples where it IS needed :)
However, I hate single quotes around HTML attributes, so I can't bring myself
to use that format anyway. :-)
Well, that's where we come down to personal opinion... personally, seeing \" 100's of times in a script doesn't turn me on at all :)
