yippits api PHP json解碼

Question

我正在嘗試循環並從此響應中獲取詳細信息。無論結果如何，「交易」部分顯然都會重複。我用這個解碼json響應

$jsonurl = "http://api.yipit.com/v1/deals/?key=&tag=spa"; 
$json = file_get_contents($jsonurl,0,null,null); 
$json_output = json_decode($json); 

但不完全確定如何通過此循環與foreach？任何幫助入門將非常感激！

Answer 1

$json_output->response->deals - 您收到的所有交易的數組。所以，你需要遍歷它來獲取它的信息。

例如這個代碼將回顯所有交易descritions：

foreach($json_output->response->deals as $deal) 
{ 
    echo $deal->description.'<br />'; 
} 

[] - 指陣列。它可以使用循環迭代。 {} - 手段對象（StdClass實例）。其屬性可通過->訪問。

例如處理大的圖像可以retrived就像這樣（在以前的foreach環的情況下）：

echo $deal->images->image_big;

Answer 2

json_decode()實際上應該對象歸還給您。爲了訪問這些屬性，您可以使用echo $json_output->meta->code來獲取200或$json_output->deals[0]->business->id以獲取第一筆交易的業務ID。請注意0​​和[]之間的差異

我總是建議使用var_dump($json_output)，這樣您就可以在解碼後清楚地看到對象的結構。
