php - 如何将多维与特定值合并

Question

我在合并二维数组时遇到了问题

我有三个具有相同月份的数组

第一个数组:(求职者)

Array
(
    [0] => Array
        (
            [MONTH] => 5
            [jobseeker] => 4
        )

    [1] => Array
        (
            [MONTH] => 6
            [jobseeker] => 4
        )

)

第二个数组:(公司)

Array
(
    [0] => Array
        (
            [MONTH] => 6
            [company] => 11
        )

)

第三个数组:(工作)

Array
(
    [0] => Array
        (
            [MONTH] => 6
            [job] => 20
        )

)

我试过这段代码:

$total_stats = array_merge_recursive($jobseeker_stats, $company_stats, $job_stats);

我希望输出是:

Array
(
     [0] => Array
        (
            [MONTH] => 5
            [jobseeker] => 4
        )
     [1] => Array
        (
            [MONTH] => 6
            [jobseeker] => 4
            [company] => 11
            [job] => 20
        )

您需要使用 array_column() , array_search()与 foreach()

$seconArrayMonths =  array_column($array2,'MONTH');
$thirdArrayMonths =  array_column($array3,'MONTH');


foreach($array1 as &$arr){
    $secondArrayMonthKey = array_search($arr['MONTH'],$seconArrayMonths);
    if($secondArrayMonthKey !== false){
        $arr['company'] = $array2[$secondArrayMonthKey]['company'];
    }
    $thirdArrayMonthKey = array_search($arr['MONTH'],$thirdArrayMonths);
    if($thirdArrayMonthKey !== false){
        $arr['job'] = $array3[$secondArrayMonthKey]['job'];
    }

}

print_r($array1);
