打印一個遞歸數組

Question

有人可以幫我打印這個json解碼數組的「text」值嗎？ 我沒有回聲$的obj [「文字」]我得到了一個空白:(

啊，我做的var_dump，所以編輯後它說，它的1個元素的數組內的20個元素的數組:-) 代碼42次我來到解決方案，因爲真棒Fangel幫助打印文本需要放置以下行： echo $ obj [0] [「text」];

$obj=[ 
     { 
      "created_at":"Mon Sep 03 05:00:30 +0000 2012",

Answer 1

這是必經之路打印它：echo $obj[0]["text"];

Answer 2

http://php.net/manual/en/function.json-decode.php

ASSOC

爲TRUE時，返回的對象將被轉換成關聯 陣列。

當你設置爲真第二個參數，你應該做的，而不是echo $obj["text"];的$obj->text;因爲，它在手動，第二個參數，如果爲true，力json_decode返回即使是在JSON對象關聯數組說。

就我所見，您的JSON中有一個對象數組。所以在json解碼之後，你也應該有一個對象數組。只需使用foreach循環要經過所有項目的排列和打印文本：

foreach($obj as $item) { 
    echo $item->text + "<br/>"; 
} 

或類似這樣的關聯數組（如果json_decode第二個參數是真實的）：

foreach($obj as $item) { 
    echo $item["text"] + "<br/>"; 
}
