That works too.

That also works.
Full stop is the concatenation operator, but php also has the quite unique
mechanism for inserting variables directly into strings.
$foo .= $bar;
is just short for
$foo = $foo . $bar; and they both concatenate the two variables.
But this works as well, just in a slightly different way:
$foo = "$foo$bar";
Variables inside double qoutes are replaced with their values. inside single
qoutes they'r not evaluated, but interpreted literally.
