PHP Json_解码多维数组

php json

PHP Json_解码多维数组,php,json,multidimensional-array,Php,Json,Multidimensional Array,我试图在PHP中解码json代码的一部分。json看起来像： "title":"A Title Here", "images":[ { "coverType":"fanart", "url":"some_random_file_here.jpg" }, { "coverType":"banner", "url":"another_random_file_here.jpg" }, { "coverType":"poster", "url":"yet

我试图在PHP中解码json代码的一部分。json看起来像：

"title":"A Title Here",
"images":[

{
    "coverType":"fanart",
    "url":"some_random_file_here.jpg"
},
{
    "coverType":"banner",
    "url":"another_random_file_here.jpg"
},
{
    "coverType":"poster",
    "url":"yet_another_random_file_here.jpg"
}

],

$somevariable = $item['series']['tvdbId'];

我想获取标题下的url：“banner”

我可以使用以下代码轻松解析标题：

$itemNr = 0;
            foreach($json as $item) {
                $mytitle = $item['title'];
                echo $mytitle;
$itemNr++;

使用相同的概念，我的代码看起来会是什么样子。请注意，我已经简化了JSON的代码。上面代码中未显示的某些项目的实际php如下所示：

"title":"A Title Here",
"images":[

{
    "coverType":"fanart",
    "url":"some_random_file_here.jpg"
},
{
    "coverType":"banner",
    "url":"another_random_file_here.jpg"
},
{
    "coverType":"poster",
    "url":"yet_another_random_file_here.jpg"
}

],

$somevariable = $item['series']['tvdbId'];

非常感谢您的建议

谢谢

如果您可以访问图像键，则：

<?php
$json = <<<JSON
{
    "title":"A Title Here",
    "images":[
        {
            "coverType":"fanart",
            "url":"some_random_file_here.jpg"
        },
        {
            "coverType":"banner",
            "url":"another_random_file_here.jpg"
        },
        {
            "coverType":"poster",
            "url":"yet_another_random_file_here.jpg"
        }
    ]
}
JSON;

$json = json_decode($json);
print_r($json);

foreach ($json->images as $img)
{
    if ( $img->coverType == "banner" )
    {
        echo 'Image Cover Type: ' .$img->coverType .'<br/>';
        echo 'URL: ' .$img->url .'<br/>';
    }
}
?>

给出：

图片封面类型：横幅

URL:另一个_random_文件_here.jpg

更新：

您链接到的JSON文件似乎无效，每个系列后面都缺少大括号。以下是更正后的JSON和代码：
