PHP foreach not returning the string i need

i got this little problem with an array. I have products that belong to one or more categories and i need to display them as an array. First, this is my code to get categories from product 1 only:

    $prod = $this->getDi()->productTable->load(1);
    $prod_cat = $prod->getCategories();
    print_r($prod_cat);

This will output this:

Array ( [0] => 1 )

So far so good. However, i need to do the same for all the products in existence at once. So im doing this:

$act_prod = Array ( 0 => 1 ); //array can contain more than one product, as of now it only contains one

foreach ($act_prod as $act) {
         $cat = $this->getDi()->productTable->load($act);
         $active_cat[$act] = $cat->getCategories(); 
        } 
print_r($active_cat);

But this will output:

Array ( [1] => Array ( [0] => 1 ) )

which is not what i need but this instead:

Array ( [0] => 1 )

I cant figure out whats wrong. Could you please give me a hint?

Thank you.

$cat->getCategories() returns an array, you add an array to another array each iteration, so is the result.

If you want to merge all the categories to a array, use array_merge instead:

$active_cat = array();
foreach ($act_prod as $act) {
    $cat = $this->getDi()->productTable->load($act);
    $active_cat = array_merge($active_cat, $cat->getCategories()); 
}

And side note, it's quite not efficient do such loop, you may get all the categories with just one query.
