数组合并NO（+）UNION或merge（）

Question

$array1 = [ "month" => "Jan", "count" => "20" , "month" => "feb", "count" => "2" ];
$array2 = [ "month" => "Jan", "count" => "50" , "month" => "feb", "count" => "27" ];

Expected array after merge the above 2 arrays

$fianlarray = ["month" => "jan" , "count"=>"20" , "count" => "50" , 
               "month" => "feb" , "count" => "2", "count" => "27" ];

i've tried array_merge and union but no result. thanks in advance

Answer 1

You cannot do such a thing :

$fianlarray = ["month" => "jan" , "count"=>"20" , "count" => "50" , 
               "month" => "feb" , "count" => "2", "count" => "27" ];

here you define multiple times the keys "month","count" which is forbidden...
