You want to match the second expression starting after that Purpose</p>.
Use:
preg_match("/<(\/p)>/s", $matches_new[0], $m_new);
.. check the documentation on php.net for that function, you don't pass
it an offset - it takes an optional flag to return the offset along with
the matches. You may have been thinking of:
strpos($haystack, $needle, [$offset])
- which is what I would recommend using for the first part (since you
want the first occurrence), then using that with substr() to get the
first occurrence of a closing </p> to get the string you want.
[ warning - wholly untested code :) ]
$start = strpos($fpRead, "Purpose</p>");
$end = strpos($fpRead, "</p>", $start);
// make what we're doing clearer for the mailing list
// also helps in case offsets are a little strange.
$length = $end - $start;
$what_i_want = $substr($fpRead($start,$length));
