从匹配的数组键创建多维数组

<?php
// 一维数组
$array1 = array('a' => 1, 'b' => 2, 'c' => 3);
$array2 = array('a' => 4, 'b' => 5, 'c' => 6);
$array3 = array('a' => 7, 'b' => 8, 'c' => 9);

// 匹配的数组键
$keys = array('a', 'b', 'c');

// 创建多维数组
$multiArray = array();
foreach ($keys as $key) {
    $multiArray[$key] = array($array1[$key], $array2[$key], $array3[$key]);
}

// 打印多维数组
print_r($multiArray);
?>

            [1] => 6
            [2] => 9
