結合兩個數組

Question

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

我有兩個數組：

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

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

我想將它們結合起來，使第一個數組的第一個值將是第二個數組的第一個鍵。

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

Answer 1

可以用array_combine做到這一點：

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

或滾你自己：

$new=array(); 
foreach($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);
