Question

我正在连接到一个返回此嵌套对象值的API。

我如何迭代每个[＆＃34;数字：protected＆＃34;]？这对我来说是新的，我只想返回＆＃34;数字：protected＆＃34;。

 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] => 
    )

 )

我有什么东西但没有显示出来：

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

请帮忙。提前谢谢。

所以这里发生的是你的API在数组中以对象形式返回类的实例。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>";

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

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

希望这会有所帮助。
