$name = "alvin" . " " . "alexander";
Of course I could have also done that like this:
$name = "alvin " . "alexander";
but I wanted to show an example with more than two strings.
There's another way to do this that's relatively common, especially when you're printing output, like this:
$first_name = "alvin"; $last_name = "alexander"; $full_name = "$first_name $last_name"; print "$full_name\n";
As you can see from the previous example, the two variables are merged together to create the third variable in this line of code:
$full_name = "$first_name $last_name";
In either of these examples, the output would be the same:
