Один из способов - использовать DOMDocument:
$doc = new DOMDocument();
$doc->loadHTML($homepage);
$table = $doc->getElementsByTagName("table")->item(/* Find out which one it is */)
$rows = $table->getElementByTagName("tr")
for ($i = 0; $i length; $i++)
{
$row = $rows->item($i);
/* Find columns and add it to your array */
}
