如何在我的多维关联数组中回显正确的键？

Question

我的objective是创建一个多维关联数组，里面有朋友和他们的梦想（用户输入）。我认为（希望）我可以接近完成它，但是在回应最后一步时我得到了一个不需要的结果：

我试图在第 22 行回显包含 'friend' 名称的句子。结果我得到的不是用户输入的名称，而是 'Array'。例：Array的梦想是：攀登珠穆朗玛峰

有谁知道我怎么知道这里朋友的名字的？

A line/string 应该为每个填写的单独梦想回显。为了清楚起见，我包括了打印功能，稍后将删除。谢谢！

<?php

$friends = readline('How many friends should we ask for their dreams? ');
$array = [];

if (is_numeric($friends) == false) {
    exit("This is not a number." . PHP_EOL);
} else if ($friends == 0) {
    exit("This is not valid input." . PHP_EOL);
} else {
    for ($i = 1; $i <= $friends; $i++) {
        $name_key = readline('What is your name? ');
        $number_dreams = readline('How many dreams are you going to enter? ');
        for ($x = 1; $x <= $number_dreams; $x++) {
            $dream_value = readline('What is your dream? ');
            $array[$name_key][] = $dream_value;
        }
        print_r($array);
    }
    foreach ($array as $friend) {
        foreach ($friend as $key => $value) {
            echo $friend . ' has this as their dream: ' . $value . PHP_EOL;
        }
    }
}

组装 $array 后试试这个：

foreach ($array as $frndNm=>$dreams){ 
        foreach($dreams as $dream){ 
         echo( $frndNm.' dream is '.$dream); 
        } 
}
