在PHP中合并具有不同长度的多维数组

我需要合并两个具有以下格式的数组：

array(9) 
{ 
[0]=> array(1) { ["BLA"]=> string(7) "bis 050" } 
[1]=> array(1) { ["BLA"]=> string(7) "bis 060" } 
[2]=> array(1) { ["BLA"]=> string(7) "bis 070" } 
[3]=> array(1) { ["BLA"]=> string(7) "bis 080" } 
[4]=> array(1) { ["BLA"]=> string(7) "bis 090" } 
[5]=> array(1) { ["BLA"]=> string(7) "bis 100" } 
[6]=> array(1) { ["BLA"]=> string(7) "bis 110" } 
[7]=> array(1) { ["BLA"]=> string(7) "bis 120" } 
[8]=> array(1) { ["BLA"]=> string(6) "gr 120" } 
} 

array(5) 
{ 
[0]=> array(2) {
   ["BLA"]=> string(7) "bis 050" 
   ["Amount"]=> string(3) "832" } 
[1]=> array(2) { 
   ["BLA"]=> string(7) "bis 060" 
   ["Amount"]=> string(3) "448" } 
[2]=> array(2) { 
   ["BLA"]=> string(7) "bis 090" 
   ["Amount"]=> string(4) "1216" } 
[3]=> array(2) { 
   ["BLA"]=> string(7) "bis 100" 
   ["Amount"]=> string(4) "1024" } 
[4]=> array(2) { 
   ["BLA"]=> string(7) "bis 110" 
   ["Amount"]=> string(3) "896" } 
}

我试过了array_merge()，array_merge_recursive()但是没有用。我的目标是将第二个键及其值从array2（Amount）写入第一个键（BLA）相同的数组1中。另外"Amount":"0"，如果array2中没有相应的值，我想写。有什么办法用PHP做到这一点？

结果应如下所示：

    Result:
{ 
[0]=> array(2) { 
   ["BLA"]=> string(7) "bis 050"  
   ["Amount"]=> string(3) "832" } 
[1]=> array(2) { 
   ["BLA"]=> string(7) "bis 060"  
   ["Amount"]=> string(3) "448" } 
[2]=> array(2) { 
   ["BLA"]=> string(7) "bis 070" 
   ["Amount"]=> string(1) "0" }  
[3]=> array(2) { 
   ["BLA"]=> string(7) "bis 080" 
   ["Amount"]=> string(1) "0" }  
[4]=> array(2) { 
   ["BLA"]=> string(7) "bis 090" 
   ["Amount"]=> string(4) "1216" }
[5]=> array(2) { 
   ["BLA"]=> string(7) "bis 100" 
   ["Amount"]=> string(4) "1024" }  
[6]=> array(2) { 
   ["BLA"]=> string(7) "bis 110" 
   ["Amount"]=> string(3) "896" } 
[7]=> array(2) { 
   ["BLA"]=> string(7) "bis 120" 
   ["Amount"]=> string(1) "0" }  
[8]=> array(2) { 
   ["BLA"]=> string(6) "gr 120" 
   ["Amount"]=> string(1) "0" } 
}

我整理了一个快速演示，似乎可以解决您的问题。让我知道您是否需要任何其他帮助。

<?php

$arrOne = array(
    array("BLA" => "bis 050"),
    array("BLA" => "bis 060"),
    array("BLA" => "bis 070"),
    array("BLA" => "bis 080"),
    array("BLA" => "bis 090"),
    array("BLA" => "bis 100"),
    array("BLA" => "bis 110"),
    array("BLA" => "bis 120"),
    array("BLA" => "gr 120")
);

$arrTwo = array(
    array("BLA" => "bis 050","Amount" => "832"),
    array("BLA" => "bis 060","Amount" => "448"),
    array("BLA" => "bis 090","Amount" => "1216"),
    array("BLA" => "bis 100","Amount" => "1024"),
    array("BLA" => "bis 110","Amount" => "896")
);


$arrOutput = array();

foreach($arrOne as $arrOneValue) {
    $searchKey = $arrOneValue["BLA"];

    foreach($arrTwo as $arrTwoValue) {
        if($arrTwoValue["BLA"] == $searchKey) {
            $arrOutput[] = array("BLA" => $searchKey, "Amount" => $arrTwoValue["Amount"]);
            continue 2; // Continue the outer loop
        }
    }

    // We didn't find the key
    $arrOutput[] = array("BLA" => $searchKey, "Amount" => "0");
}

var_dump($arrOutput);
?>

产生如下内容：

array(9) { 
    [0]=> array(2) { ["BLA"]=> string(7) "bis 050" ["Amount"]=> string(3) "832" } 
    [1]=> array(2) { ["BLA"]=> string(7) "bis 060" ["Amount"]=> string(3) "448" } 
    [2]=> array(2) { ["BLA"]=> string(7) "bis 070" ["Amount"]=> string(1) "0" } 
    [3]=> array(2) { ["BLA"]=> string(7) "bis 080" ["Amount"]=> string(1) "0" } 
    [4]=> array(2) { ["BLA"]=> string(7) "bis 090" ["Amount"]=> string(4) "1216" } 
    [5]=> array(2) { ["BLA"]=> string(7) "bis 100" ["Amount"]=> string(4) "1024" } 
    [6]=> array(2) { ["BLA"]=> string(7) "bis 110" ["Amount"]=> string(3) "896" } 
    [7]=> array(2) { ["BLA"]=> string(7) "bis 120" ["Amount"]=> string(1) "0" } 
    [8]=> array(2) { ["BLA"]=> string(6) "gr 120" ["Amount"]=> string(1) "0" } 
}
