In theory, not at all.
A very quick search for the preg_match_all function on PHP.net turns up the
answer in the documentation [1].

In short, preg_match_all returns a multi-dimensional array. You either play
with the default, or tell PHP how you want that array formatted.

So, $results[0] is an array containing the text that matches the pattern you
provided. From then on, $results[n] (n>0) will match for each capture you
provide.
