As said in the comments this is not a good idea to parse HTML using regex. Anyway, here is how you could achieve it using preg_match_all assuming $input contains the input string :

<?php

preg_match_all('#<tr[^>]*>(.*?)</tr>#is', $input, $lines);

$result = array();

foreach ($lines[1] as $k => $line) {
    preg_match_all('#<td[^>]*>(.*?)</td>#is', $line, $cell);

    foreach ($cell[1] as $cell) {
        $result[$k][] = trim($cell);
    }
}

var_dump($result);

?>
