PHP JSON解碼

有人可以幫我解碼這個JSON到PHP？PHP JSON解碼

這裏是JSON：

{ 
    "queue": { 
     "active_lang": "en",

     "scripts": [],

      "tv" 
     ], 
     "darwin": false, 
     "timeleft": "4:05:09", 
     "mb": "534.79", 
     "noofslots": 1,

     "nzb_quota": "",

     "kbpersec": "32.17", 
     "speedlimit": "", 
     "webdir": "C:\\Program Files (x86)\\SABnzbd\\interfaces\\Plush\\templates", 
     "queue_details": "0", 
     "diskspace2": "703.54" 
    } 
}

我到目前爲止這樣的代碼：

$APIArray = json_decode($urlContents, true); 
    $APIqueue = ($APIArray['queue']); 
    $APIkbpersec = ($APIArray['kbpersec']); 
//  print_r($APIkbpersec); 
    echo $APIkbpersec;

，但我似乎無法打印出「kbpersec」或JSON的任何其它值。我之前和json一起工作過，但我似乎無法解決這個問題，如果有人能幫上忙，那會很棒。

$ urlContents是JSON字符串 –

是正確的JSON？爲我返回null – RiaD

您可怕的變量名稱可能是問題的一部分。試試'$ json = json_decode（...）;'並簡單地'print $ json [「queue」] [「kbpersec」]; - 另請參閱http://php.net/manual/en/language中的示例.types.array.php – mario

您的kbpersec是在您的$APIqueue變量下，而不是$APIArray之一。

你的代碼改成這樣：

$APIArray = json_decode($urlContents, true); 

$APIqueue = $APIArray['queue']; 
$APIkbpersec = $APIqueue['kbpersec']; 

echo $APIkbpersec;

或：

$APIArray = json_decode($urlContents, true); 

$APIqueue = $APIArray['queue']; 
$APIkbpersec = $APIArray['queue']['kbpersec']; 

echo $APIkbpersec;
