將數組值與前一個數組值比較

如何比較當前數組值與以前的數組值？示例如果我有以下數組並且想比較[BM1367 PD C 70] [ST00576] ['transferfrom']與先前的數組是[BM1367 PD B 85] [ST00576] ['transferfrom']？將數組值與前一個數組值比較

[BM1367 PD B 85] => Array 
     (
      [ST00576] => stdClass Object 
       (
        [transferfrom] => 102 
        [transferto] => 66 
        [BR_ID] => 102 
        [refno] => 

       ) 

      [OT01606] => stdClass Object

我已經試過：的foreach（$轉移爲$ docno => $ transfer_details）{ //做的東西在這裏 } $ previous_br =電流（array_map（ 'pick_transferfrom'，$傳輸））; \t} – redcoder

你問：

我怎麼與以前的數組值比較當前數組值

我想你可能想看看下面的PHP函數

電流（） - http://www.php.net/manual/en/function.current.php
prev（） - http://www.php.net/manual/en/function.prev.php
下一個（） - http://php.net/manual/en/function.next.php

例如：

<?php 
$transport = array('foot', 'bike', 'car', 'plane'); 
$mode = current($transport); // $mode = 'foot'; 
$mode = next($transport); // $mode = 'bike'; 
$mode = next($transport); // $mode = 'car'; 
$mode = prev($transport); // $mode = 'bike'; 
$mode = end($transport);  // $mode = 'plane'; 
?>

我能夠使用那些在計算公式，工作的偉大！比較您的前一個或下一個陣列的電流時，它也很有用。

你的STD class objects在這種情況下，一個數組，你可以按如下比較元素：假設另一個數組裏面，你所提供的陣列是

$tempArray = { 


     [BM1367 PD B 85] => Array 
      (
       [ST00576] => stdClass Object 
        (
         [transferfrom] => 102 
         [transferto] => 66 
         [BR_ID] => 102 
         [refno] => 

        ) 

       [OT01606] => stdClass Object 
        (
         [transferfrom] => 102 
         [transferto] => 66 
         [BR_ID] => 66 
         [refno] => 102 - ST00576 

        ) 

      ) 

     [BM1367 PD C 70] => Array 
      (
       [ST00576] => stdClass Object 
        (
         [transferfrom] => 102 
         [transferto] => 66 
         [BR_ID] => 102 
         [refno] => 

        ) 

       [OT01606] => stdClass Object 
        (
         [transferfrom] => 102 
         [transferto] => 66 
         [BR_ID] => 66 
         [refno] => 102 - ST00576 

        ) 

      ) 

     [BM1367 PD C 85] => Array 
      (
       [ST00576] => stdClass Object 
        (
         [transferfrom] => 102 
         [transferto] => 66 
         [BR_ID] => 102 
         [refno] => 

        ) 

       [OT01606] => stdClass Object 
        (
         [transferfrom] => 102 
         [transferto] => 66 
         [BR_ID] => 66 
         [refno] => 102 - ST00576 

        ) 

      ) 

     [BM1367 PD D 85] => Array 
      (
       [ST00576] => stdClass Object 
        (
         [transferfrom] => 102 
         [transferto] => 66 
         [BR_ID] => 102 
         [refno] => 

        ) 

       [OT01606] => stdClass Object 
        (
         [transferfrom] => 102 
         [transferto] => 66 
         [BR_ID] => 66 
         [refno] => 102 - ST00576 

        ) 

      ) 

    ) 

};

您現在可以訪問元素

$tempArray['BM1367 PD C 70']['ST0076']->transferfrom 

$tempArray['BM1367 PD B 85']['ST0076']->transferfrom

並且爲了比較它們

(int)$tempArray['BM1367 PD C 70']['ST0076']->transferfrom == (int)$tempArray['BM1367 PD B 85']['ST0076']->transferfrom
