{ 
    "hintsacross": 
    [ { "number":"1" , "hinttext":"Hurt", "hintsquare":"A1" }, 
      { "number":"5" , "hinttext":"Make a selection", "hintsquare":"A6" }, 
      { "number":"8" , "hinttext":"Frank", "hintsquare":"A10" }
    ] ,
    "hintsdown": 
    [ { "number":"1" , "hinttext":"First Greek letter", "hintsquare":"A1" },
      { "number":"2" , "hinttext":"Used footnotes", "hintsquare":"A2" }, 
      { "number":"3" , "hinttext":"Listened to", "hintsquare":"A3" }
    ] 
 }

由于某种原因，PHP 的 json_decode 没有解码这个 JSON。

提前谢谢...

附：第 25 行运行时出现错误：

$temp = json_decode($obj->hints,true);

解析错误：语法错误，C:\Program Files (x86)\Zend\Apache2\htdocs\crosswords\query.blockouts.php 中出现意外的 'hintscross' (T_STRING) /b> 第 25 行

我通过 JSONlint 验证了我的 JSON，并且出现了解析错误。

【解决方案1】：

这是无效的 JSON。尝试在“hintsdown”之前添加一个逗号并重试 json_decode。

{
    "hintsacross": [
        {
            "number": "1",
            "hinttext": "Hurt",
            "hintsquare": "A1"
        },
        {
            "number": "5",
            "hinttext": "Make a selection",
            "hintsquare": "A6"
        },
        {
            "number": "8",
            "hinttext": "Frank",
            "hintsquare": "A10"
        }
    ],
    "hintsdown": [
        {
            "number": "1",
            "hinttext": "First Greek letter",
            "hintsquare": "A1"
        },
        {
            "number": "2",
            "hinttext": "Used footnotes",
            "hintsquare": "A2"
        },
        {
            "number": "3",
            "hinttext": "Listened to",
            "hintsquare": "A3"
        }
    ]
}

顺便说一句，它有助于使用在线工具或其他验证器验证您的 JSON（我使用 JSONLint）

【解决方案2】：

   $ll="{ "hintsacross": [ { "number":"1" , "hinttext":"Hurt", "hintsquare":"A1" }, { "number":"5" , "hinttext":"Make a selection", "hintsquare":"A6" }, { "number":"8" , "hinttext":"Frank", "hintsquare":"A10" } ],
   "hintsdown": [ { "number":"1" , "hinttext":"First Greek letter", "hintsquare":"A1" }, { "number":"2" , "hinttext":"Used footnotes", "hintsquare":"A2" }, { "number":"3" , "hinttext":"Listened to", "hintsquare":"A3" } ] } "

    $ll = json_decode($ll);
    print_r($ll);

在

附近添加 (,) 逗号

],
   "hintsdown"

希望这会有所帮助

json 格式不正确。使用jsonlint.com 进行检查。您将收到错误消息，如果 json 格式正确，您也会收到一条 OK 消息。

Parse error on line 18:
...A10"        }    ]"hintsdown": [     
---------------------^
Expecting 'EOF', '}', ',', ']'

正确的json：

{
    "hintsacross": [
        {
            "number": "1",
            "hinttext": "Hurt",
            "hintsquare": "A1"
        },
        {
            "number": "5",
            "hinttext": "Make a selection",
            "hintsquare": "A6"
        },
        {
            "number": "8",
            "hinttext": "Frank",
            "hintsquare": "A10"
        }
    ],
    "hintsdown": [
        {
            "number": "1",
            "hinttext": "First Greek letter",
            "hintsquare": "A1"
        },
        {
            "number": "2",
            "hinttext": "Used footnotes",
            "hintsquare": "A2"
        },
        {
            "number": "3",
            "hinttext": "Listened to",
            "hintsquare": "A3"
        }
    ]
}
