How can I fetch only parent product categories ?

[amitturboc]

I am using $client->products->get_categories();.. It give me all categories. But I want only parent product categories.

Simply put all the values into a variable and loop through looking for parent = '0'

$categories = $client->products->get_categories();

$parentcats = array();
foreach($categories as $category) {
  if($category['parent'] == 0) {
    $parentcats[] = $category; 
  }
}

print_r($parentcats);

Yes you are correct. I know.it is possible in client end. I want filter from server end..not in client end....
