如何在一个php数组中组装两个不同的数组

Question

$arr1 = Array ( [0] => 5 [days] => 5 )
        Array ( [0] => 6 [days] => 6 ) 
        Array ( [0] => 7 [days] => 7 ) 
        Array ( [0] => 8 [days] => 8 ) 
        Array ( [0] => 9 [days] => 9 ) 
        Array ( [0] => 10 [days] => 10 ) 
        Array ( [0] => 11 [days] => 11 ) 
        Array ( [0] => 12 [days] => 12 )
        Array ( [0] => 13 [days] => 13 ) 
        Array ( [0] => 14 [days] => 14 ) 
        Array ( [0] => 15 [days] => 15 ) 
        Array ( [0] => 16 [days] => 16 ) 
        Array ( [0] => 17 [days] => 17 ) 
        Array ( [0] => 18 [days] => 18 ) 
        Array ( [0] => 19 [days] => 19 ) 
        Array ( [0] => 20 [days] => 20 ) 
        Array ( [0] => 21 [days] => 21 ) 
        Array ( [0] => 22 [days] => 22 ) 
        Array ( [0] => 23 [days] => 23 ) 
        Array ( [0] => 24 [days] => 24 ) 
        Array ( [0] => 25 [days] => 25 ) 
        Array ( [0] => 26 [days] => 26 ) 
        Array ( [0] => 27 [days] => 27 ) 
        Array ( [0] => 28 [days] => 28 ) 
        Array ( [0] => 29 [days] => 29 ) 
        Array ( [0] => 30 [days] => 30 ) 
        Array ( [0] => 31 [days] => 31 );

$arr2 = Array ( [0] => 1 [day] => 1 
                [1] => 1 [days] => 1 ) 
        Array ( [0] => 2 [day] => 2 [1] => 2 [days] => 2 ) Array ( [0] => 3 [day] => 3 [1] => 3 [days] => 3 ) Array ( [0] => 4 [day] => 4 [1] => 4 [days] => 4 );

i want to ascending-ly marge $arr1 and $arr2 and the output i expect

1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31

help me How can i do like that?

Answer 1

You can use array_column to select only days from the multi dimensional array and then use array_merge to merge the array.

Just like this

$merger=array_merge(array_column($arr2,'days'),array_column($arr1,'days'));
$merger=implode(',',$merger);

It will produce your desired out put.
