Php 如何使用多维数组格式化打印输出

我有一个多维数组，如下所示

$March = array (
    "Friday" => array(
            "1st" => 3,
            "2nd" => 10,
            "3rd" => 17,
            "4th" => 24,
            "5th" => 31 
    ),
    "Saturday" => array (
            "1st" => 4,
            "2nd" => 11,
            "3rd" => 18,
            "4th" => 25 
    ),
    "Sunday" => array (
            "1st" => 5,
            "2nd" => 12,
            "3rd" => 19,
            "4th" => 26 
    ),
    "Monday" => array (
            "1st" => 6,
            "2nd" => 13,
            "3rd" => 20,
            "4th" => 27 
    ),
    "Tuesday" => array (
            "1st" => 7,
            "2nd" => 14,
            "3rd" => 21,
            "4th" => 28 
    ),
    "Wednesday" => array (
            "1st" => 8,
            "2nd" => 15,
            "3rd" => 22,
            "4th" => 29 
    ),
    "Thursday" => array (
            "1st" => 9,
            "2nd" => 16,
            "3rd" => 23,
            "4th" => 30 
    ) 

)

我想按以下格式打印数组

[Friday] => Array ( [1st] => 3 [2nd] => 10 [3rd] => 17 [4th] => 24 [5th] => 31 )
[Saturday] => Array ( [1st] => 4 [2nd] => 11 [3rd] => 18 [4th] => 25 )
[Sunday] => Array ( [1st] => 5 [2nd] => 12 [3rd] => 19 [4th] => 26 )
[Monday] => Array ( [1st] => 6 [2nd] => 13 [3rd] => 20 [4th] => 27 ) 
[Tuesday] => Array ( [1st] => 7 [2nd] => 14 [3rd] => 21 [4th] => 28 )
[Wednesday] => Array ( [1st] => 8 [2nd] => 15 [3rd] => 22 [4th] => 29 ) 
[Thursday] => Array ( [1st] => 9 [2nd] => 16 [3rd] => 23 [4th] => 30 )

我可以使用print\u r（$March）来实现这一点；但它给了我这个输出

Array ( [Friday] => Array ( [1st] => 3 [2nd] => 10 [3rd] => 17 [4th] => 24 [5th] => 31 ) [Saturday] => Array ( [1st] => 4 [2nd] => 11 [3rd] => 18 [4th] => 25 ) [Sunday] => Array ( [1st] => 5 [2nd] => 12 [3rd] => 19 [4th] => 26 ) [Monday] => Array ( [1st] => 6 [2nd] => 13 [3rd] => 20 [4th] => 27 ) [Tuesday] => Array ( [1st] => 7 [2nd] => 14 [3rd] => 21 [4th] => 28 ) [Wednesday] => Array ( [1st] => 8 [2nd] => 15 [3rd] => 22 [4th] => 29 ) [Thursday] => Array ( [1st] => 9 [2nd] => 16 [3rd] => 23 [4th] => 30 ) ) 

我发现我可以用

print\r（$3月['Friday']）打印出我的每个数组

但这只给了我这个

Array ( [1st] => 3 [2nd] => 10 [3rd] => 17 [4th] => 24 [5th] => 31 ) 

这和这个不一样

[Friday] => Array ( [1st] => 3 [2nd] => 10 [3rd] => 17 [4th] => 24 [5th] => 31 )

请发送帮助，已经盯着w3看了几个小时。
要实现您在评论中所写的内容，您可以使用以下循环：

foreach($March as $nameOfDay => $dayArray ){
    foreach($dayArray as $key => $val){
        echo $val.' is the '.$key.' '.$nameOfDay.' in March. ';
    }
}

您没有为此使用
print\r（）
。必须编写自己的格式代码。所需的格式不是有效的PHP数组。您只需要将其显示为字符串吗？或者你想进一步操作数据吗？我需要操作数据，这是一个家庭作业，我的下一个任务是用foreach循环数组，然后像这样打印出来“3月3日是三月的第一个星期五。10号是三月的第二个星期五。17号是三月的第三个星期五。24日是三月的第四个星期五。31号是三月的第五个星期五。4号是三月的第一个星期六。11号是三月的第二个星期六。18日是三月的第三个星期六。“有学习，然后在一个简单的格式问题上被困数小时，导致挫折，否则可能会被很好地利用（实际学习）.我想当你学习编写代码时，你并没有陷入困境？并因此寻求帮助？同样，如果我排除了回答中的家庭作业部分，会怎么样？这是否会使答案变得如此不同？我的问题不是“如何声明变量”。我只需要格式方面的帮助。
