Can some one help me add some additional functionality

I was surfing the net looking for a quick and dirty way to take a table with 3 headers, 1 footer and its contents are create a comma delimited CSV file. what I came across is the following:

preg_match('/<table(>| [^>]*>)(.*?)<\/table( |>)/is',$this->raw('./PayrollReportTable.report'),$b);
$table = $b[2];
preg_match_all('/<tr(>| [^>]*>)(.*?)<\/tr( |>)/is',$table,$b);
$rows = $b[2];
foreach ($rows as $row){
preg_match_all('/<td(>| [^>]*>)(.*?)<\/td( |>)/is',$row,$b);
$out[] = strip_tags(implode(',',$b[2]));
}
$out = implode("\n", $out);
var_dump($out);

Its almost what I need, accept this solution ommits the headers (I have three remember) and the footer (only one). And I am not very good with rejex, so I was curious if some one here could me implement the missing pieces (header and footer). I would be ever so greatful. If you know of a better, cleaner, simpler, easier way please do share I am willing to try anything but over all what I have is pretty much what I want it just needs the headers and the footer.

It should be noted that the actual table being processed here comes from: $this->raw('./PayrollReportTable.report')
