循环通过 PHP 阵列而不是手动

Question

所以我了解了 for 循环，do while，for each 但我只是不知道如何编写代码，所以循环会自动创建我现在手动执行的信息（只需复制和 Pasta）

请参阅下面的代码

我的问题：-) 如何通过循环？ 我可能必须创建一个矩阵数组或如何调用 -) 如何在数组中包含 img 链接并将其插入到 html 代码中

<?php

// Available, Name , Model,  Price, Rent Location, 


$car1 = array(
    "available" => "Available",
    "name" => "Duster",
     "model" =>"Nissan", 
     "price" => 333,
     "location" => "Hollywood");

     $car2 = array(
        "available" => "Available",
        "name" => "Panzer",
         "model" =>"Bundesheer", 
         "price" => 98753,
         "location" => "Kaserne");

         $car3 = array(
            "available" => "NOT Available",
            "name" => "Hubschrauber",
             "model" =>"Pew Pew", 
             "price" => 98756,

您需要创建一个多维数组（array of arrays），更多关于 arrays这里

一旦你有了你的数组，你就可以迭代它。

$cars = [
    [
        "available" => "Available",
        "name" => "Duster",
        "model" =>"Nissan",
        "price" => 333,
        "location" => "Hollywood"
    ],
    [
        "available" => "Available",
        "name" => "Schiff",
        "model" =>"Öltanker",
        "price" => 223123213132,
        "location" => "Baltisches Meer"
    ],
    [
        "available" => "NOT Available",
        "name" => "Hubschrauber",
        "model" =>"Pew Pew",
        "price" => 98756,
        "location" => "Dschungel"
    ],
    [
        "available" => "Available",
        "name" => "Panzer",
        "model" =>"Bundesheer",
        "price" => 98753,
        "location" => "Kaserne"
    ],
];

foreach ($cars as $car) {
    echo $car['available'];
}
