PHP显示数组相同的键具有多个值

Question

我有两个数组，我需要在数组相同的Key时获取内容 我使用array_intersect_key获取相同的密钥并返回此结果：

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

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

结果

array_intersect_key(Array1,Array2);它返回：[london] = "20,london";

但我需要展示[london] = "20,london"; and [london] = "40,london";

或类似的内容[london] = "20,london|40,london";

没有循环我有一个大文件

谢谢！

Answer 1

您好我已经尝试过这段代码来获得没有循环的最接近的结果。这可能会对你有所帮助。

的代码

$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;

<强>结果

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

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

)

让我知道它是否有效。祝你好运。

的更新

这个怎么样？它将返回相同的结果。

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;
