php - 我如何比较两个数组并将唯一记录添加到表中

Question

我正在尝试比较和添加从表 B 到表 A 的唯一记录，如果存在重复记录，则跳过重复记录，并在下一条记录上执行搜索，如果找不到匹配项，则添加它。使用 [SalesDescription] 字段进行比较

我尝试使用 array_unique 和 array_differ、array_intersect，但这些函数都无法消除重复/对我不起作用。

这是添加数据的代码

  $records=array(
      'SalesDescription'         => $row['SalesDescription'],
      'SO Qty' => $row['Quantity'],
      'WO Qty'          => $row['Reference'],
      'SO Date'          => $row['TransactionDate'],
      'Color'         => $row['DistNumber'], 
      'SO#'         => $row['Reference'], 
      'Promised Date'         => $row['GoodThruDate'], 



     );

    $tv->addRecord($tableId, $records);//calls addRecord() function

表A:记录我想向其中添加数据的表

Array ( 
      [id] => 3054535376 
      [table_id] => 50240233993

                        [SO Qty] => 1.0000000000000000000

                        [CALC PROMISED DATE] => 2014-10-30 
                        ) 
   ) 

表B:记录我想从中获取数据的表

       [SalesDescription] => 18X5X12 1/8 SOLID FORKLIFT TIRE PRESS-ONS 
       [13] => [PartNumber] => [14] => 18X5X12 1/8 SOLID FORKLIFTTIRE 
       [ItemDescription] => 18X5X12 1/8 SOLID FORKLIFTTIRE
       ) 

Answer 1

这有点麻烦，但您可以先创建一个包含键(即 SalesDescription 值)的数组。Double SalesDescription 将互相覆盖，然后您将其转换回来:

<?php

$tableB = array(....)

$temp = array();
foreach($tableB as $value) {
  $temp[$value['SalesDescription']] = $value;
}
$tableB = array();
foreach($temp as $value) {
  $tableB[] = $value;
}

// Now $tableB has only unique SalesDescription's!
