将数据导入阵列

Question

我在一些基于商家的电子商务网站上工作。提交订单时存在问题。问题是，当我选择相同的商家时，订单将成功存储，但是当我从不同的商家选择多个产品时，我的功能是通过未定义的偏移误差：1。这是我的功能。

public function post_order(){
    $data = Input::all();
    $count = count($data['invoice_no']);
    $order = array();
    for($i=0; $i<$count; $i++){
        if(!empty($data['invoice_no'][$i])){
            array_push($order, array(
                'order_no'          => $data['order_no'][$i],
                'invoice_prefix'    => $data['invoice_prefix'][$i],
