foreach里面的foreach迭代双倍时间

Question

I have a code in which foreach inside another foreach.

$order_id = '1,1,8';
$order_no_first= 'F,SH,C';

$order_id1 = explode(",", $order_id);
$order_no_first1 = explode(',', $order_no_first);

foreach($order_id1 as $ord_id){
    foreach($order_no_first1 as $ord_no_first){
        if($ord_id != '') {
            $this->receipt->chageBagStatus($ord_id, $ord_no_first);
            $add = $this->receipt->addJobOrderNew($ord_id, $ord_no_first, $bag_no);
        }
    }
}

Now the above code iterates 3 times resulting 9 rows in mysql.

//Current Output

order_id    orderr_no_first
--------    ---------------
   8              C
   8              SH
   8              F
   1              C
   1              SH
   1              F
   1              C
   1              SH
   1              F

The above output is wrong. I want the output as below,

//Required Output

order_id    orderr_no_first
--------    ---------------
   8              C
   1              SH
   1              F

I know it's because am using nested foreach. but I don't know how to solve this issue. Is there any solution. Thankyou.

just use one foreach like this,

foreach($order_id1 as $key => $ord_id){
        if($ord_id != '') {
            $this->receipt->chageBagStatus($ord_id, $order_no_first1[$key]);
            $add = $this->receipt->addJobOrderNew($ord_id, $order_no_first1[$key], $bag_no);
        }
}
