php - 使用 PHP 数组将 JSON 内容保存在 Mysql 中 [调试]

Question

我正在尝试将 JSON 数据解析到我的数据库中。

一切都很顺利，直到嵌套数组为止。

我试图将其保存为 MYSQL(phpMyAdmin) 中的数组，但没有结果。

这是我的 Json 文件:

因为有点大，我让你知道它是怎样的。

有主舰。船有标题、id、个人资料图像等。这些都保存到我的数据库中。但在 Ship_facts 这样的选项中，有一个数组 { launch_year, width etc... } 并与字符串数组一起保存在我的数据库中。

我的PHP代码是这样的:

<?php 

require '../config.php';
$string = file_get_contents("newjson11.json");
$arr = json_decode($string, true);

for ($i = 0; $i < 788; $i++) {


    $title                = $arr['ships'][$i]['title'];   
    $id                   = $arr['ships'][$i]['id'];    
    $profile_image        = $arr['ships'][$i]['profile_image_href'];
    $cover_image          = $arr['ships'][$i]['cover_image_href'];  
    $href                 = $arr['ships'][$i]['href'];
    $html_href            = $arr['ships'][$i]['html_href'];
    $size                 = $arr['ships'][$i]['size'];
    $style                = $arr['ships'][$i]['style'];
    $gratuities           = $arr['ships'][$i]['gratuities'];
    $ship_facts           = $arr['ships'][$i]['ship_facts'];

    $dining               = $arr['ships'][$i]['dining'];

    $operator             = $arr['ships'][$i]['operator'];

    //I tried :

    // 1. $deckplans = $arr['ships'][$i]['deckplans']['name'];
    // 2. $deckplans = $arr['ships'][$i]['deckplans'][$i]['name'];
    // 3. $deckplans = $arr['ships']['deckplans']['name'];
    // 4. $deckplans = $arr['ships']['deckplans'][$i]['name'];



    $deckplans            = $arr['ships'][$i]['deckplans'];

    $cruises              = $arr['ships'][$i]['cruises'];

    $query = "INSERT INTO ships
                        (title, id, profile_image_href, 
                        cover_image_href, href, html_href, 
                        size, style, gratuities, 
                        ship_facts, dining, deckplans, 
                        operator)"; 
    $query .= "VALUES( '{$title}', '{$id}', '{$profile_image}', 
                       '{$cover_image}', '{$href}', '{$html_href}', 
                       '{$size}', '{$style}', '{$gratuities}', 
                       '{$ship_facts}', '{$dining}', '{$operator}')";

    $dataatodb = mysqli_query($con, $query);

    if(!$dataatodb){
        echo("Error" . mysqli_errno($con));
    } else {
        echo '<h1>Succesfull Data Transfer</h1>';
    }
} 
?>

我还尝试使用 implode("",$arr) 存储在数据库中，并使用 explode 来回显和 print_r 但仍然没有任何结果;

请问有人可以帮忙吗？

这就是它的保存方式，看起来就像我的数据库

Answer 1

这是一个您试图放入数据库的 php array()。您可以将该部分编码回 json 字符串并将该字符串保存在数据库中。

$ship_facts           = json_encode($arr['ships'][$i]['ship_facts']);
