PHP Show Array same Key wth multiple Value

Question

I have two arrays and I need to get the content when the array same Key I'm using array_intersect_key to get the same key and it returns this result:

Array1 :
(
[NewYork] = "5,NewYork";
[london] = "20,london";
[Pari] = "40,Pari";
)

Array2 :
(
[China] = "14,China";
[london] = "40,london";
[Tokyo] = "2,Tokyo";
)

Result

array_intersect_key(Array1,Array2); it return : [london] = "20,london";

But I need to show [london] = "20,london"; and [london] = "40,london";

or something like this [london] = "20,london|40,london";

Without a loop I have a large file

Thank you!

You can do this: $res=array_intersect_key($arr1,$arr2); foreach($result as $k=>$v) { $final[$k] = $arr1[$k] ."|".$arr2[$k]; }. $final will be your result. — Faisal Rehman

Use $result instead of $res like $result = array_intersect_key($arr1, $arr2); foreach($result as $k=>$v) { $final[$k] = $arr1[$k] ."|".$arr2[$k]; } — Faisal Rehman

Hi I have tried this code to get the closest result without loop. This might help you.

Code

$array1['NewYork'] = "5,NewYork";
$array1['london'] = "20,london";
$array1['Tokyo'] = "40,Pari";


$array2['China'] = "14,China";
$array2['london'] = "40,london";
$array2['Tokyo'] = "2,Tokyo";


$res1 = array_intersect_key($array1,$array2);
$res2 = array_intersect_key($array2,$array1);

echo "<pre>";
print_r(array_merge_recursive($res1,$res2));
die;

Result

Array
(
    [london] => Array
        (
            [0] => 20,london
            [1] => 40,london
        )

    [Tokyo] => Array
        (
            [0] => 40,Pari
            [1] => 2,Tokyo
        )

)

Let me know if it works. Good Luck.

Update

How about this? It will return the same result.

function myfunction($a,$b)
{
if ($a!=$b)
  {
  return 0;
  }
  return ($a>$b)?1:-1;
}
$array1['NewYork'] = "5,NewYork";
$array1['london'] = "20,london";
$array1['Tokyo'] = "40,Pari";


$array2['China'] = "14,China";
$array2['london'] = "40,london";
$array2['Tokyo'] = "2,Tokyo";

$res1 = array_merge_recursive($array1,$array2);
$res2 = array_uintersect_assoc($res1,$array1,"myfunction");

echo "<pre>";
print_r($res2);
die;
