What does the period do in this statement: $svarname = "other_site" . $i; Concactenation?

The period does indeed concatenate the two clauses.

However, because you are using double quotes, you could also do:

  $svarname = "other_site $i";

and PHP would substitute in the $i.

Whereas:

  $svarname = 'other_site $i';

would be taken literally, as it uses single quotes.
