Code:

//This calls echo ONE time, but with many arguments...
echo $firstname, ' ', $lastname;

The speed boost is just marginal but since it's just as easy to write a comma intead of a dot so why not?

Actually double quotes are slower to use, and when you don't need your string to be parsed it's better to use single quotes. I allways use singlequotes when i'm working with pure strings, but when it's makes the code easier to read I use double quotes. This won't probably be the bottleneck of your app but it's just so easy to use those single quotes (or commas) instead. =)

Code:

$a = 'world';


$b = "hello $a"; //Easy.

$b = 'hello ' . $a; //Not so easy.

I don't wan't to start a war or something so maybe we can go back to the subject of this thread.
