循環通過多維數組和打印

Question

我有一個數組，我想從中獲取某些信息並使用php/html（即遊戲，編號，評級）輸出它。儘管我只從輸出中的第一個數組中獲取信息，但我已經完成了基礎知識。我知道循環是我需要做的，儘管我不確定如何一次返回多個記錄。一個數組中的某些信息可能不在另一個數組中，因爲您可以看到第一個數組中沒有[info]。

這裏是我的代碼：

<?php 

$review = $developer->api('/source'); 

    function d($d){ 
     echo '<pre>'; 
     print_r($d); 
     echo '</pre>'; 
    } 

    d($review[data][0][game]); 
    d($review[data][0][game][rating]); 
?> 

這是輸出：

Array([data] => Array ([0] => Array ([id] => 2010_1110 [from] => Array ([name] => Pebkac [id] => 11001010 ) [game] => Array ([id] => 2112 [name] => New Game [rating] => Array ([action] => 9 [graphics] => 10)) [comments] => Array ([data] => Array ([0] => Array ([id] => 2010_1111 [from] => Array ([name] => My Friend [id] => 10100110) [message] => hi there. [created_time] => 8:00 P.M.))))) 

[paging] => Array ([previous] => url1 [next] => url2)) 

Array([data] => Array ([1] => Array ([id] => 2010_1112 [from] => Array ([name] => Pebkac [id] => 11001010 ) [game] => Array ([id] => 5050 [name] => Another Game [rating] => Array ([action] => 8 [graphics] => 8)) [info] => [created_time] => 8:59 P.M. [owns] => Array ([data] => Array ([0] => Array ([id] => 20100112 [name] => Friend Two))) [comments] => Array ([data] => Array ([0] => Array ([id] => 2010_1113 [from] => Array ([name] => My Friend [id] => 10100110) [message] => hi there. [created_time] => 9:00 P.M.))))) 

Answer 1

如果我正確理解你的問題，你需要的是一個foreach循環，它無關，與多維。

Answer 2

根據你想要做什麼，你可以做一個嵌套for循環，或者如果你有n個維度，你可以遞歸調用你的函數，直到結果不再是一個數組。事情是這樣的：

function printNode($node) { 
    foreach ($node as $nodeKey => $nodeValue) { 
     if (is_array($nodeValue)) { 
      printNode($nodeValue); 
     } else { 
      print $nodeValue; 
     } 
    } 
}
