合并两个数组[重复]

Question

可能重复：
Elegant way to merge two arrays as key value pairs in PHP?

我有两个数组：

Array
(
    [0] => A
    [1] => B
    [2] => C
    [3] => D
    [4] => E
)

Array
(
    [0] => APPLE
    [1] => BANANNA
    [2] => CRANBERRY
    [3] => DURIAN
    [4] => EGGPLANT
)

我想将它们组合起来，使第一个数组的第一个值成为第二个数组的第一个键。

Array
(
    [A] => APPLE
    [B] => BANANNA
    [C] => CRANBERRY
    [D] => DURIAN
    [E] => EGGPLANT
)

Answer 1

可以使用array_combine：

$new=array_combine($a, $b);

或自己动手：

$new=array();
foreach($a as $idxA=>$valA)
{
   $new[$valA]=$b[$idxA];
}

Answer 2

$array1 = Array
(
    [0] => A
    [1] => B
    [2] => C
    [3] => D
    [4] => E
);

$array2 = Array
(
    [0] => APPLE
    [1] => BANANNA
    [2] => CRANBERRY
    [3] => DURIAN
    [4] => EGGPLANT
);

$answer = array_combine($array1, $array2);
print_r($answer);
