   public function getCheckoutForm(){
   $arr = array(
        'cmd' => '_cart',
        'business' => 'some@mail',
        'no_shipping' => '1',
        'upload' => '1',
        'return' => 'url',
        'cancel_return' => 'url1',
        'no_note' => '1',
        'currency_code' => 'url2',
        'bn' => 'PP-BuyNowBF');

   $cpt=1;
   foreach($this->items as $item){
        $arr1[] = array(
            'item_number_'.$cpt.'' => $item['item_id'],
            'item_name_'.$cpt.'' => $item['item_name'],
            'quantity_'.$cpt.'' => $item['item_q'],
            'amount_'.$cpt.'' => $item['item_price']
            );
        $cpt++;
   }
    return array_merge($arr,$arr1[0],$arr1[1]);
}

这将返回这样的数组：

    Array
(
    [cmd] => _cart
    [business] => some@mail
    [no_shipping] => 1
    [upload] => 1
    [return] => url1
    [cancel_return] =>url2
    [no_note] => …
