将2个数组合并为地图数组

Question

如何合并两个类似的数组

$letters = ["A","B","C"];
$words = ["Alpha","Bravo","Charlie"];

放入类似的地图数组中

$result = [
    ["letter" => "A", "word" => "Alpha"],
    ["letter" => "B", "word" => "Bravo"],
    ["letter" => "C", "word" => "Charlie"]];

[尽可能高效，整洁，我尝试查看内置函数，但似乎找不到任何帮助。

Answer 1

这将导致：

$letters = ["A","B","C"];
$words = ["Alpha","Bravo","Charlie"];

$result = array_map(function( $letter, $word ){
    return [ 'letter' => $letter, 'word' => $word ];
}, $letters, $words);
