【问题描述】：
我尝试了各种解决方案，但似乎没有一个能满足我的需求——或者我不明白如何改变它们来解决我的特定问题。基本上，我从我的 SQL 服务器返回一堆行。查询如下所示：
$params = array(&$search, &$search, &$search, &$search, &$search, &$search, &$search, &$search);
$tsql = "SELECT Item.ID, Item.ItemLookupCode, nitroasl_pamtable.ManufacturerPartNumber, SupplierList.ReorderNumber, Item.Notes,
Item.Description, Item.ExtendedDescription, Item.Quantity, nitroasl_pamtable.SpoofStock, Item.Price,
nitroasl_pamtable.PAM_Keywords, Item.PictureName
FROM Item
INNER JOIN nitroasl_pamtable ON Item.ID = nitroasl_pamtable.ItemID
INNER JOIN SupplierList ON Item.ID = SupplierList.ItemID
WHERE (Item.ItemLookupCode LIKE '%' + ? + '%' AND Price > 0.00 AND WebItem = 1)
OR (Item.ID LIKE '%' + ? + '%' AND Price > 0.00 AND WebItem = 1)
OR (nitroasl_pamtable.ManufacturerPartNumber LIKE '%' + ? + '%' AND Price > 0.00 AND WebItem = 1)
OR (SupplierList.ReorderNumber LIKE '%' + ? + '%' AND Price > 0.00 AND WebItem = 1)
OR (Item.Notes LIKE '%' + ? + '%' AND Price > 0.00 AND WebItem = 1)
OR (Item.Description LIKE '%' + ? + '%' AND Price > 0.00 AND WebItem = 1)
OR (Item.ExtendedDescription LIKE '%' + ? + '%' AND Price > 0.00 AND WebItem = 1)
OR (nitroasl_pamtable.PAM_Keywords LIKE '%' + ? + '%' AND Price > 0.00 AND WebItem = 1)";
// Allows us to determine the number of rows returned
$cursorType = array('Scrollable' => SQLSRV_CURSOR_KEYSET);
$getProducts = sqlsrv_query($conn, $tsql, $params, $cursorType);
然后我使用以下内容将行放入数组中：
// Put results into an array
while( $row = sqlsrv_fetch_array( $getProducts, SQLSRV_FETCH_ASSOC))
{
$results['results'][] = $row;
}
$results['results'] 在我搜索“tp-ac1750 时看起来像这样（删除了一些返回的列以便于查看） ：
Array (
[results] => Array (
[0] => Array (
[ItemLookupCode] => TP-AC1750
[ReorderNumber] => ARCHERC7
)
[1] => Array (
[ItemLookupCode] => TP-AC1750
[ReorderNumber] => N82E16833704177
)
[2] => Array (
[ItemLookupCode] => TP-AC1750
[ReorderNumber] => 7681617
)
[3] => Array (
[ItemLookupCode] => TP-AC1750
[ReorderNumber] => ARCHERC7
)
)
[keywords] => tp-ac1750
)
我希望数组看起来像这样：
Array (
[results] => Array (
[0] => Array (
[ItemLookupCode] => TP-AC1750
[ReorderNumber] => Array (
[0] => ARCHERC7
[1] => N82E16833704177
[2] => 7681617
)
)
)
)
我试过了：
- array_unique
- array_unique_recursive
- array_walk_recursive
- array_merge_recursive
- 还有更多（各种组合）
但我似乎无法做到正确。这是我现在正在尝试的：
// Remove duplicates
$results['results'] = merge_duplicates( $results['results'] );
//***********************************************
// Merge duplicate arrays and their values
//***********************************************
function merge_duplicates( $array )
{
// Build temporary array for array_unique
$tmp = array();
foreach( $array as $key => $value ) {
$tmp[ $key ] = $value;
}
// Find duplicates in temporary array
$tmp = array_unique( $tmp, SORT_REGULAR );
// Remove duplicates from original array
foreach( $array as $key => $value ) {
if ( !array_key_exists( $key, $tmp ) ) {
unset( $array[ $key ] );
}
}
return $array;
}
有没有办法完成这种类型的合并？有没有办法在 SQL 查询期间合并这些重复项？任何意见，将不胜感激！在此先感谢:)
更新（正在使用的完整数组）
这是我需要使用此合并的实际数组（我仍然想使用 ItemLookupCode 作为唯一键，但合并所有其他同级键）：
Array (
[0] => Array (
[ID] => 8265
[ItemLookupCode] => TP-AC1750
[ManufacturerPartNumber] => Archer C7
[ReorderNumber] => ARCHERC7
[Notes] => TP-LINK Archer C7 AC1750 Routr
[Description] => TP-LINK Archer C7 AC1750 Routr
[ExtendedDescription] => TP-Link Archer C7 Wireless-AC1750 Dual-Band Gigabit Router
[Quantity] => 0
[SpoofStock] =>
[Price] => 129.9500
[PAM_Keywords] =>
[PictureName] => tp-ac1750.jpg
)
[1] => Array (
[ID] => 8265
[ItemLookupCode] => TP-AC1750
[ManufacturerPartNumber] => Archer C7
[ReorderNumber] => N82E16833704177

)
[3] => Array (

这并不是您真正想要的，但它可能有用。 geneticcoder.blogspot.com/2015/05/…

那篇文章中有一些可能性。我将进行实验，看看会发生什么:) 这些方法有一种反复出现的主题，我不知道该怎么做......其中许多函数，如
array_merge_recursive，希望将两个数组传递给函数进行比较。 ..我需要比较许多数组（不仅仅是两个）... -
您仍然在
INNER JOINing 并（可能）为单个结果集中的每个Item返回许多行。这不是我推荐的。 -
这个问题是在我们开始在另一个线程中讨论之前提出的 :) 所以这是我最初的查询......
