如何显示此json数据中的变量

时间：2013-08-24 23:40:16

标签： php json curl jsonp

所以我试图让这个工作无济于事。下面是我的PHP文件和我的JSON数据。

注意我必须先将JSONP转换为JSON。这工作得很好。现在看看这个疯狂的数据数组，我不知道如何在foreach循环中获取变量。任何帮助都会有很好的帮助。

由于

MYFILE.php 

$url = "http://www.SwingAcademy.com/web/external/api.ashx?method=getLessons&     callback=?";  
$groupID = "43AB3367-F58D-487E-B2C6-2571A3A3508C";
$num_results = "";

$post_data = array ( 
    "NUMRESULTS" => $num_results,
    "GROUPID" => $groupID,
    "OWNERID" => ''

);  


$curl_options = array(
    CURLOPT_URL => $url ,
    CURLOPT_POST => true,
    CURLOPT_POSTFIELDS => http_build_query( $post_data ),
    CURLOPT_HTTP_VERSION => 1.0,
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_HEADER => false
);

$curl = curl_init();

curl_setopt_array( $curl, $curl_options );

$result = curl_exec( $curl );

//echo $result;

function jsonp_decode($jsonp, $assoc = false) { // PHP 5.3 adds depth as third parameter   to json_decode
   if($jsonp[0] !== '[' && $jsonp[0] !== '{') { // we have JSONP
       $jsonp = substr($jsonp, strpos($jsonp, '('));
    }
    return json_decode(trim($jsonp,'();'), $assoc);
}
echo "<pre>";
var_dump(jsonp_decode($result, true));
echo "</pre>";

switch (json_last_error()) {
    case JSON_ERROR_NONE:
        echo ' - No errors';
    break;
    case JSON_ERROR_DEPTH:
        echo ' - Maximum stack depth exceeded';
    break;
    case JSON_ERROR_STATE_MISMATCH:
        echo ' - Underflow or the modes mismatch';
    break;
    case JSON_ERROR_CTRL_CHAR:
        echo ' - Unexpected control character found';
    break;
    case JSON_ERROR_SYNTAX:
        echo ' - Syntax error, malformed JSON';
    break;
    case JSON_ERROR_UTF8:
        echo ' - Malformed UTF-8 characters, possibly incorrectly encoded';
    break;
    default:
        echo ' - Unknown error';
    break;
   }

   echo PHP_EOL;

   foreach($result['VIDEOS'] as $p)
   {
     echo '

     Lesson Info: '.$p['LESSONTEXT'].' '.$p['LESSONID'].'

     Image Link: '.$p['THUMBNAIL'].'

     ';
   }

Warning: Invalid argument supplied for foreach() in

要注意这是为JavaScript构建的，但我需要将它与PHP一起使用。所以我做了所有的转换和处理。我现在可以知道我有这些数据如何在foreach循环中显示它并回显变量。

这些数据的存储方式看起来很陌生。

echo "<pre>";
var_dump(jsonp_decode($result, true));
echo "</pre>";
$arrResult = jsonp_decode($result, true);
.
.
.
foreach($arrResult['VIDEOS'] as $p)

答案 1 :(得分：1)

在使用之前，您需要将jsonp_decode的结果分配给变量$result：

$result = jsonp_decode($result, true);
