Php 如何使用键在数组中追加值而不被覆盖

我在foreach循环中得到结果，现在我想用键形成一个新数组，用新数据形成该数组。现在，当我尝试分配数据时，它会被覆盖到上一个，因为它不会得到新的索引。到目前为止，我是如何做到这一点的：

foreach ($result as $key) {
    $pickup_location = $key->locationid;
    if (isset($pickup_location)) {
        $pickup_location = $this->db->get_where('locations', array('id' => $pickup_location ))->row();
        if (!empty($pickup_location)) {
            $supplier_dashboard['pickup_location_name'] = $pickup_location->name_en;
        }
    } 

    $dropoff_location = $key->location_dropoff;
    if (isset($dropoff_location)) {
        $dropoff_location = $this->db->get_where('locations', array('id' => $dropoff_location ))->row();
        if (!empty($dropoff_location)) { 
            $supplier_dashboard['dropoff_location_name'] = $dropoff_location->name_en;
        }
    }
    $car_make = $key->car_id;

    if (isset($car_make)) {
        $car_details = $this->db->get_where('chauffeur_rates', array('chauffeur_id' => $car_make))->row();
        if (!empty($car_details)) {
            $supplier_dashboard['car_make'] = $car_details->chauffeur_make;
        }
    }
}
return $supplier_dashboard;
}

我得到的数组是：

Array
(
 [pickup_location_name] => Seoul Downtown
 [dropoff_location_name] => Disneyland Paris
 [car_make] => makecar
)

然而，我至少有7个位置名称和汽车品牌，而不是作为一个新的数组添加它覆盖了前一个，我应该得到的结果如下

Array
[0](
 [pickup_location_name] => Seoul Downtown
 [dropoff_location_name] => Disneyland Paris
 [car_make] => makecar
)
Array
[1](
 [pickup_location_name] => Seoul 1
 [dropoff_location_name] => Disneyland 1
 [car_make] => makecar
)
Array
[2](
 [pickup_location_name] => Seoul 2
 [dropoff_location_name] => Disneyland 2
 [car_make] => makecar
)
... upto 7

您必须将$key添加到添加记录的数组中

使用

而不是

$supplier_dashboard['pickup_location_name'] = //your code

您必须将$key添加到添加记录的数组中

使用

而不是

$supplier_dashboard['pickup_location_name'] = //your code

---

您直接在最顶端的集合中设置值，而不是将项添加到数组中

安装

$myobject['foo'] = $value;

您需要执行（其中，

$iteration

是循环中的当前位置）

请尝试以下操作：

$carItemNumber = 0;
foreach ($result as $key) {
    $pickup_location = $key->locationid;
    if (isset($pickup_location)) {
        $pickup_location = $this->db->get_where('locations', array('id' => $pickup_location ))->row();

        if (!empty($pickup_location)) {
         $supplier_dashboard[$carItemNumber]['pickup_location_name'] = $pickup_location->name_en;
        }
    } 

    $dropoff_location = $key->location_dropoff;
    if (isset($dropoff_location)) {
        $dropoff_location = $this->db->get_where('locations', array('id' => $dropoff_location ))->row();

        if (!empty($dropoff_location)) { 
         $supplier_dashboard[$carItemNumber]['dropoff_location_name'] = $dropoff_location->name_en;
        }
    }

    $car_make = $key->car_id;

    if (isset($car_make)) {
        $car_details = $this->db->get_where('chauffeur_rates', array('chauffeur_id' => $car_make))->row();

        if (!empty($car_details)) {
         $supplier_dashboard[$carItemNumber]['car_make'] = $car_details->chauffeur_make;
        }
    }

    $carItemNumber++;
}
return $supplier_dashboard;

每次循环数组的键总是相同的，这就是为什么要忽略结果。你需要放一把独一无二的钥匙。你可以试试这个

$i = 0; //First key
foreach ($result as $key){
    $supplier_dashboard[$i]['pickup_location_name'] = $pickup_location->name_en;
    $i++; //add +1 to the key so the next element not overrides
}
