如果可以访问图像键，然后：

$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 .'
';

echo 'URL: ' .$img->url .'
';

}

}

?>

给出：

图片封面类型：横幅

网址： another_random_file_here.jpg

更新：

您链接到的JSON文件似乎无效，每个系列后都缺失大括号。这里的修正JSON和代码：

$json = <<
