如何使用php将重复的值键合并为一个数组

<?php
function mergeDuplicates($array) {
    $result = array();
    foreach ($array as $value) {
        if (!in_array($value, $result)) {
            $result[$value] = array($value);
        } else {
            $result[$value][] = $value;
        }
    }
    return $result;
}

// 示例用法
$array = array(1, 2, 3, 2, 4, 3, 5, 6, 5);
$result = mergeDuplicates($array);

print_r($result);
?>

Array
(
    [1] => Array
        (
            [0] => 1
        )

    [2] => Array
        (
            [0] => 2
            [1] => 2
        )

    [3] => Array
        (
            [0] => 3
            [1] => 3
        )

    [4] => Array
        (
            [0] => 4
        )

    [5] => Array
        (
            [0] => 5
            [1] => 5
        )

    [6] => Array
        (
            [0] => 6
        )
)
