如何訪問此多維數組的鍵？

Question

我已經將我的facebook post的JSON輸出轉換為數組，並且要在post中搜索特定的關鍵字，我必須訪問[message]鍵，因此如何訪問以下[0]和[1]鍵的[message] ：

Array
(
    [0] => Array
        (
            [id] => 459037547545408_496947267087769
            [from] => Array
                (
                    [category] => Internet/software
                    [name] => Open Pdf Library
                    [id] => 459037547545408
                )

            [message] => No
            [privacy] => Array
                (
                    [value] => 
                )

            [type] => status
            [status_type] => mobile_status_update
            [created_time] => 2013-12-17T22:55:55+0000
            [updated_time] => 2013-12-17T22:55:55+0000
        )

    [1] => Array
        (
            [id] => 459037547545408_496947230421106
            [from] => Array
                (
                    [category] => Internet/software
                    [name] => Open Pdf Library
                    [id] => 459037547545408
                )

            [message] => Hello star
            [privacy] => Array
                (
                    [value] => 
                )

            [type] => status
            [status_type] => mobile_status_update
            [created_time] => 2013-12-17T22:55:46+0000
            [updated_time] => 2013-12-17T22:55:46+0000
        )

    )

Answer 1

<?php
  echo $array[0]["message"];
  echo "<br>";
  echo $array[1]["message"];
?>

應該做的工作

Answer 2

假設$ foo是您的完整數組...

$foo[0]['message'];
$foo[1]['message'];

或循環：

foreach ($foo as $bar) {
   echo $bar['message'];
}
