If matches are found for parenthesized substrings of

third argument <parameter>regs</parameter>, the matches will be stored
in the elements of the array <parameter>regs</parameter>.
</para>
<para>
$regs[1] will contain the substring which starts at the first left
parenthesis; $regs[2] will contain the substring starting at the
second, and so on. $regs[0] will contain a copy of the complete string
matched.

If the optional parameter <parameter>regs</parameter> was not passed or
