使用file_get_contents将JSON转换为PHP数组

Question

我试图使用杂志api获取以下json内容.json的输出是这样的.我希望下面的json转换为php数组.

{
"bpath": "http://www.sampledomain.com/",
"clist": [
    {
        "cid": "11",
        "display_type": "grid",
        "ctitle": "abc",
        "acount": "71",
        "alist": [
            {
                "aid": "6865",
                "adate": "2 Hours ago",
                "atitle": "test",
                "adesc": "test desc",
                "aimg": "",
                "aurl": "?nid=6865",
                "weburl": "news.php?nid=6865",
                "cmtcount": "0"
            },

            {
                "aid": "6857",
                "adate": "20 Hours ago",
                "atitle": "test1",
      "adesc": "test desc1",
      "aimg": "",
                "aurl": "?nid=6857",
                "weburl": "news.php?nid=6857",
                "cmtcount": "0"
            }
        ]
    },
    {
        "cid": "1",
        "display_type": "grid",
        "ctitle": "test1",
  "acount": "2354",
        "alist": [
            {
                "aid": "6851",
                "adate": "1 Days ago",
                "atitle": "test123",
      "adesc": "test123 desc",
      "aimg": "",
                "aurl": "?nid=6851",
                "weburl": "news.php?nid=6851",
                "cmtcount": "7"
            },
            {
                "aid": "6847",
                "adate": "2 Days ago",
                "atitle": "test12345",
      "adesc": "test12345 desc",
      "aimg": "",
                "aurl": "?nid=6847",
                "weburl": "news.php?nid=6847",
                "cmtcount": "7"
            }
        ]
    },

]
}

我的代码看起来像这样.

<?php 
$json_url = "http://api.testmagazine.com/test.php?type=menu";
$json = file_get_contents($json_url);
$data = json_decode($json, TRUE);
echo "<pre>";
print_r($data);
echo "</pre>";
?>

上面的代码返回一个空数组.:(如何将上述JSON转换为php对象数组.我很无奈.

谢谢哈恩

您提供的JSON示例无效.使用此JSON Validator http://jsonlint.com/在线查看.您需要删除第59行的额外逗号.

你有一个有效的json,你可以使用这个代码将其转换为数组.

json_decode($ json,true);

Array

Answer 2

你JSON不是一个有效的字符串,正如P. Galbraith上面告诉你的那样.

这是解决方案.

<?php 
$json_url = "http://api.testmagazine.com/test.php?type=menu";
$json = file_get_contents($json_url);
$json=str_replace('},

]',"}

]",$json);
$data = json_decode($json);

echo "<pre>";
print_r($data);
echo "</pre>";
?>

使用此代码它将适合您.
