我正在连接到一个返回此嵌套对象值的API。

如何迭代每个 ["数字：受保护"]？这对我来说是新事物，我只想返回"数字：受保护"。

 Array
 (
[0] => SDK2go'seat2go Object
    (
        [status:protected] => Vacant
        [number:protected] => D,10,A,STR3,ROOM
        [passenger:protected] => 
        [price:protected] => 
    )
[1] => SDK2go'seat2go Object
    (
        [status:protected] => Vacant
        [number:protected] => D,15,A,STR3,ROOM
        [passenger:protected] => 
        [price:protected] => 
    )
[2] => SDK2go'seat2go Object
    (
        [status:protected] => Vacant
        [number:protected] => D,16,A,STR3,ROOM
        [passenger:protected] => 
        [price:protected] => 
    )
[3] => SDK2go'seat2go Object
    (
        [status:protected] => Vacant
        [number:protected] => D,17,A,STR3,ROOM
        [passenger:protected] => 
        [price:protected] => 
    )
[4] => SDK2go'seat2go Object
    (
        [status:protected] => Vacant
        [number:protected] => D,18,A,STR3,ROOM
        [passenger:protected] => 
        [price:protected] => 
    )
[5] => SDK2go'seat2go Object
    (
        [status:protected] => Vacant
        [number:protected] => D,19,A,STR3,ROOM
        [passenger:protected] => 
        [price:protected] => 
    )
 )

我有一些东西，但没有显示任何内容：

 foreach($sList as $list){
   echo $list['number:protected'];  
 }

请帮忙。提前谢谢。

所以这里发生的事情是，你的API在数组中以对象形式返回一个类的实例。要模仿它，请查看以下代码：

<?php
namespace SDK2go; 
class seat2go
{
    protected $status;
    protected $number;
    protected $passenger;
    protected $price;
    public function __construct($status, $number)
    {
        $this->status = $status;
        $this->number = $number;
    }
    public function get_status()
    {
        echo $this->status;
    }
    public function get_number()
    {
        echo $this->number;
    }
}
$arr = array(
    new seat2go("Vacant", "D,10,A,STR3,ROOM"),
    new seat2go("Vacant", "D,15,A,STR3,ROOM"),
    new seat2go("Vacant", "D,16,A,STR3,ROOM")
);

echo "<pre>";
print_r($arr);
echo "</pre>";

以上将为您提供print_r结果。因此，为了访问这些属性，您必须调用类应该具有的getter函数。如下：

foreach ($arr as $a) {
    echo $a->get_status();
    echo $a->get_number();
}

希望这有帮助。
