使用键和添加值合并两个多维数组

Question

我想使用 key(product_id) 合并两个数组并添加该值(usage)。 阵列 1

大批 ( [0] => 数组 ( [名称] => 重新安排服务 [用法] => 1 [product_id] => 8 ) [1] => 数组 ( [名称] => 添加图像 [用法] => 1 [product_id] => 5 ) [2] => 数组 ( [名称] => 每个日历事件 [用法] => 1 [product_id] => 14 ) )

数组 2

大批 ( [0] => 数组 ( [名称] => 添加图像 [用法] => 1 [product_id] => 5 ) [1] => 数组 ( [名称] => 安排 A 服务 [用法] => 3 [product_id] => 11 ) [2] => 数组 ( [名称] => 每个日历事件 [用法] => 2 [product_id] => 14 ) [3] => 数组 ( [名称] => 销售业绩仪表板 [用法] => 2 [product_id] => 30 ) [4] => 数组 ( [名称] => 引用 [用法] => 1 [product_id] => 32 ) )

我需要一个像这样合并和添加使用值的输出。

大批 ( [0] => 数组 ( [名称] => 添加图像 [用法] => 2 [product_id] => 5 ) [1] => 数组 ( [名称] => 安排 A 服务 [用法] => 3 [product_id] => 11 ) [2] => 数组 ( [名称] => 每个日历事件 [用法] => 3 [product_id] => 14 ) [3] => 数组 ( [名称] => 销售业绩仪表板 [用法] => 2 [product_id] => 30 ) [4] => 数组 ( [名称] => 引用 [用法] => 1 [product_id] => 32 ) [5] => 数组 ( [名称] => 重新安排服务 [用法] => 1 [product_id] => 8 ) )

这是我创建数组的代码

foreach($query->rows as $product){ $top_products[]=数组（ '名称'=>$产品['名称'], '使用'=>$product['pusage'], 'product_id'=>$product['product_id'] ); } foreach($query_2->rows as $product){ $top_point_products[]=数组（ '名称'=>$产品['名称'], 'usage'=>$product['p_usage'], 'product_id'=>$product['product_id'] ); }

Answer 1

$first =数组（ 大批（ "name" => "重新安排服务", “使用” => 1， "product_id" => 8 ), 大批（ "名称" => "添加图像", “使用” => 1， "product_id" => 5 ), 大批（ "name" => "每个日历事件", “使用” => 1， "product_id" => 14 ) ); $秒=数组（ 大批（ "名称" => "添加图像", “使用” => 1， "product_id" => 5 ), 大批（ "name" => "调度服务", “使用” => 3， "product_id" => 11 ), 大批（ "name" => "每个日历事件", “使用” => 2， "product_id" => 14 ), 大批（ "名称" => "销售业绩仪表板", “使用” => 2， "product_id" => 30 ), 大批（ "名称" => "报价", “使用” => 1， "product_id" => 32 ) ); $result = array_unique(array_merge($first,$second), SORT_REGULAR);

使用 array_unique & array_merge

Answer 2

使用array_merge function，像这样：

$C = array_merge($A, $B);
print_r($C);

Read manual Array merge

Answer 3

试试这个代码

<?php

$array1=array
(
    0 => array(
            'name' => "Reschedule A Service", 
            'usage' => 1,
            'product_id' => 8
        ),

    1 => Array
        (
            'name' => "Adding An Image",
            'usage' => 1,
            'product_id' => 5
        ),

    2 => Array
        (
            'name' => "Each Calendar Event",
            'usage' => 2,
            'product_id' => 14
        )

);

$array2=array
(
    0 => Array
        (
            'name' => "Adding An Image",
            'usage' => 1,
            'product_id' => 5
        ),

    1 => Array
        (
            'name' => "Schedule A Service",
            'usage' => 3,
            'product_id' => 11
        ),

    2 => Array
        (
            'name' => "Each Calendar Event",
            'usage' => 5,
            'product_id' => 14
        ),

    3 => Array
        (
            'name' => "Sales Performance Dashboard",
            'usage' => 2,
            'product_id' => 30
        ),

    4 => Array
        (
            'name' => "Quote",
            'usage' => 1,
            'product_id' => 32
        )

);

$product_id1=array_column($array1, 'product_id');  
$product_id2=array_column($array2, 'product_id');  

$new=array_intersect($product_id1,$product_id2);

foreach ($new as $key => $value) {
    if(in_array($new[$key],$product_id2)){
        $array2[array_search($new[$key],$product_id2)]['usage']+=$array1[$key]['usage'];
      }
}
$new1=array_diff($product_id1,$product_id2);
foreach ($new1 as $key => $value) {
        $array2[]=$array1[$key];
 }

foreach ($array2 as $key => $value) {
    echo "[".$key."]=><br>";
    foreach ($value as $key1 => $value1) {
        echo "&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp";
        echo "[".$key1."]=>".$value1."<br>";

    }
    echo "<br>";
}
?>

输出

[0]=> [名称]=>添加图像 [用法]=>2 [product_id]=>5

[1]=> [名称]=>安排服务 [用法]=>3 [product_id]=>11

[2]=> [name]=>每个日历事件 [用法]=>7 [product_id]=>14

[3]=> [名称]=>销售业绩仪表板 [用法]=>2 [product_id]=>30

[4]=> [名称]=>报价 [用法]=>1 [product_id]=>32

[5]=> [name]=>重新安排服务 [用法]=>1 [product_id]=>8

Answer 4

使用array_merge 和一个简单的foreach 循环来检查您的状况并更新usage值。

见下文

$result = array_merge($arrArray1, $arrArray2);

$result2 = array(); 

foreach($result as $key => $value){
        if(array_key_exists($value['product_id'], $result2)){
               $result2[$value['product_id']]['usage'] +=  $value['usage'];
        } else{
            $result2[$value['product_id']] = $value;
        }
}

print_r($result2);

如果你想重置你的结果数组索引，像这样再次使用array_merge

$result2 = array_merge($result2); 

希望这会有所帮助
