php - Scraping a table using Simple HTML Dom -

i trying scrape product table,

http://www.dropforyou.com/search2.php?mode=search&posted_data%5bcategoryid%5d=2&posted_data%5bsearch_in_subcategories%5d=on

i need product id, quantity , price.

since site uses cookies , post form grabbing site curl. works fine. loading simple html dom $html = str_get_html($content);

i have been able load table values array, can't label them. come in 0,1,2 , can't tell what's what.

i tried using different method posted here on stackoverflow, gives me fatal error: call member function find() on non-object in

my working code isn't labeled

$content = curlscraper($urltoscrape);  $html = str_get_html($content);  $tds = $html->find('table',2)->find('td');  $num = null; foreach($tds $td) {     $num[] = $td->plaintext; }  echo '<pre>'; var_dump ($num); echo '</pre>'; 

the code found on stackoverflow gives me fatal error: call member function find() on non-object in

$content = curlscraper($urltoscrape);  $html = str_get_html($content);  foreach($html->find('tr',2) $page) { $item['sku'] = $page->find('td',0)->plaintext; $item['product'] = $page->find('td',1)->plaintext; $item['qty'] = $page->find('td',2)->plaintext; $item['description'] = $page->find('td',3)->plaintext; $item['price'] = $page->find('td',4)->plaintext;  $table[] = $item; }  print_r($table); 

try initialize variable foreach function , use code. don't line created error?

 $line = $html->find('tr',2);   foreach($line $page) { //var_dump($page) //you can check array $item['sku'] = $page->find('td',0)->plaintext; $item['product'] = $page->find('td',1)->plaintext; $item['qty'] = $page->find('td',2)->plaintext; $item['description'] = $page->find('td',3)->plaintext; $item['price'] = $page->find('td',4)->plaintext;  $table[] = $item; }
