在PHP我需要接受id,lat,lan,name,url,yipit_url,yipit_id,img_bg, city, zip等，但我不知道如何表達一個PHP頁面上那些json對象。請幫幫我。

感謝， Enamul

呃，json_decode怎麼樣？ http://php.net/manual/en/function.json-decode.php – sberry

是的，我知道它應該用json_decode來完成。但我不知道該怎麼做。 – user1559230

*。「是的，我知道它應該與json_decode做，但我不知道該怎麼做」 *

好了，不知何故你得到的數據到一個變量，假設$data

$array=json_decode($data, true);

會轉換到這一點，在這種情況下，有其他數組的數組並且裏面的id

變量要看到整個事情print_r($array);和查看源代碼，或echo '<pre>'; print_r($array);

因此，爲了得到你想要需要遍歷數組中位，但你想要的是在很多的要素之一在陣列locations所以我們需要通過他們迭代

foreach ($array['response']['deals']['active']['locations'] as $location) 
{ 
    echo 'id:'.$location['id']; 
    echo 'lat':$location['lat']; 
    //ect 
}

，或者你可以挑選的第一個

echo $array['response']['deals']['active']['locations'][0]['id'];

它沒有工作。說未定義指數：活躍 – user1559230

我正在做它盲目。調試它。 – Popnoodles

尤其是你可能想看看json_decode()

一個小例子：

<?php 

function JSONPrepare($json) { 
    // This will convert ASCII/ISO-8859-1 to UTF-8. 
    // Be careful with the third parameter (encoding detect list), because 
    // if set wrong, some input encodings will get garbled (including UTF-8!) 
    $input = mb_convert_encoding($json, 'UTF-8', 'ASCII,UTF-8,IS0-8859-1'); 

    // Remove UTF-8 BOM if present, json_decode() does not like it. 
    if (substr($input, 0, 3) == pack("CCC", 0xEF, 0xBB, 0xBF)) { 
     $input = substr($input, 0, 3); 
    } 

    return $input; 
} 

foreach (json_decode(JSONPrepare($my_json), true) as $k => $v) { 
    // process the array here 
} 
?>

json_decode將JSON轉換成一個PHP對象。

使用$response = json_decode($json);其中$ JSON是你已經張貼以上，那麼JSON：

echo $response->deals->business->id; // 11009 
echo $response->deals->business->locations[0]->id; //974228 
echo $response->deals->ypit_url; // http://yipit.com/h...y-boot-camp-up-to-81-off-42/

甚至可以將這些數據作爲數組輕鬆解析爲對象。

$parsedData = json_decode($jsondata, 1);

print_r（$ parsedData）;
