如何在php

Question

我有一个多维数组

array:2 [▼
    "lamborghini" => array:1 [▼
        "cars" => array:5 [▼
          0 => "1"
          1 => "4"
          2 => "2"
          3 => "5"
          4 => "7"
        ]
      ]
    "ferrari" => array:1 [▼
        "cars" => array:1 [▼
          0 => "8"
        ]
      ]
    ]

我试图像这样实现可能的输出

Lamborghini
1 4 2 5 7

ferrari
8

我试过这个方法

foreach($cars as $car)
{
    foreach($car as $product)
    {
        for($i=0; $i<count($product); $i++)
        {
            echo $product[$i];
        }
    }
}

我实现的输出就是这个

142578

任何人都可以帮助我实现可能的输出吗？它还应该打印第一个数组名称。例如

lamborghini
1 4 2 5 7

Answer 1

试试这个：

$cars = [
    'lamborghini' => [
        'cars' => [1, 2, 3, 4],
    ],
    'ferrari' => [
        'cars' => [1],
    ],
];

foreach($cars as $make => $cars) {
    echo $make . "<br>";
    foreach($cars as $models) {
        echo implode(' ', $models) . "<br>";
    }
}

我不知道您希望如何显示结果，但您可以删除. <br>代码。

Answer 2

你可以改为

<?php 
foreach($car as $fer){
    foreach($cars as $lamb) {
      echo "Lamborghini: ".$lamb;
    }
   echo "Ferrari: ".$fer;
}
?>

这样它会首先循环羊羔，然后循环法拉利

Answer 3

这将获得所需的输出：

foreach($car as $car_k => $car)
{
 foreach($car as $product => $num_car)
 {
    echo $car_k. ':' .implode(',',$num_car);
    echo "<br/>"

 }
}
