PHP比較兩個數組，但他們（或ALT方法）周圍的foreach

Question

所以我有這個數組：

Array 
(
    [0] => Array 
     (
      [Page] => Array 
       (
        [id] => 2 
       ) 

      [PageRevision] => Array 
       (
        [PageId] => 1 
        [PageRevisionId] => 3 
        [goldMaster] => 0 
       ) 

      [PageLanguage] => Array 
       (
        [name] => Contact Page 
       ) 

      [PageSetting] => Array 
       (
        [url] => contact2 
       ) 

     ) 

    [1] => Array 
     (
      [Page] => Array 
       (
        [id] => 2 
       ) 

      [PageRevision] => Array 
       (
        [PageId] => 1 
        [PageRevisionId] => 2 
        [goldMaster] => 1 
       ) 

      [PageLanguage] => Array 
       (
        [name] => Contact Page 2 
       ) 

      [PageSetting] => Array 
       (
        [url] => contact 
       ) 

     ) 

) 

什麼，我需要做的是確定，從給出的兩個數組，如果他們中的一個有比另一個更高的PageRevisionId，如果它的goldMaster設置爲0.但是我正在努力尋找任何方法來做到這一點。

Answer 1

if ($array[0]['PageRevision']['PageRevisionId'] > $array[1]['PageRevision']['PageRevisionId'] 
&& $array[0]['PageRevision']['goldMaster'] == 0) { 
    // your code 
} 

Answer 2

您可以在您使用此代碼與無限數量的元素的主陣列：

$max_pageRevisionId = 0; 
$max_goldMaster = 0; 

foreach($myarray as $key => $value) { 
    if($value['PageRevision']['PageRevisionId'] > $max_pageRevisionId) { 
     $max_pageRevisionId = $value['PageRevision']['PageRevisionId']; 
     $max_goldMaster = $value['PageRevision']['goldMaster']; 
    } 
} 

if($max_goldMaster > 0) { 
    // Do something 
} else { 
    // Do something else 
} 

Answer 3

$elem = ($array [0]['PageRevision']['PageRevisionId'] > $array [1]['PageRevision']['PageRevisionId'])? 
1: 
0; 

var_dump ($array [0]['PageRevision']['goldMaster '] == 0)
