Question

这是我的第一篇文章，所以你好！

想知道我可以从这个md数组中得到我的结果吗？它给了我意想不到的结果。我找了答案，但不确定我应该问什么问题..

这是数组[使用var_dump]：

的相关部分的示例

["Attendee"] => array(11) 
                  { 
                    ["id"]=> int(148) 
                    ["firstname"]=> string(5) "dave" 
                    ["lastname"]=> string(6) "davey"`
                  }

这是我的foreach代码，用于获取每位与会者的名字和姓氏：

foreach ($the_info_array['body']['Registrations'] as $registrations)
{
    foreach ($registrations as $regvalue)
    {
        echo $regvalue['firstname'].” “.$regvalue['lastname'];
    }
    echo “<br>”;
}

打印：

a a2 2 5 5 dave davey
a a2 2 5 5 scott davey
a a2 2 5 5 bill davey

等

而不是我想要的东西，即：

dave davey
scott davey
bill davey

我哪里错了，＆amp;什么是额外的字符？
在此先感谢社区给予的任何帮助！

编辑＆gt;＆gt;

奇怪的是，如果我将回声改为

echo $regvalue['firstname'];

打印：

a25dave
a25scott
a25bill

和

echo $ regvalue ['firstname']。“”;

打印

a 2 5 dave
a 2 5 scott
a 2 5 bill

这是完整的数组减去几条记录，因为我似乎无法发布那么多字符：

//此外，不知道是否相关，但数组来自最初的json解码

问题是你在注册中的每个数组上循环，即使其中大多数都不是参与者（即$regvalue将是第二个循环e.t.c中第一个循环状态的id。）。

尝试：

foreach ($the_info_array['body']['Registrations'] as $registrations)
{
        echo $registrations['Attendee']['firstname']." ".$registrations['Attendee']['lastname'];
    echo "<br>";
}

从多维数组中检索结果
