查找PHP中两个多维数组之间的差异

Question

我有两个包含数组和对象的多维数组。

$new = [
    'a' => 'b',
    'c' => (object)[
        'd' => [1 => 11, 2 => 12],
        'f' => 'Hello',
    ],
];

$old = [
    'a' => 'b',
    'c' => (object) [
        'd' => [1 => 11, 2 => 22],
        'f' => 'Goodbye',
    ],
];

我正在尝试使用下面的函数查找这两个数组之间的差异，但是当将两个对象一起比较时，结果似乎是错误的。如何更改此功能以获得正确的输出？

function compare($array1, $array2)
    {
        $result = array();
        foreach ($array1 as $key => $value) { 
            if (is_array($value)) { 
            if (array_key_exists($key, $array2)) { 
                    $recursiveArrayDiff = compare($value, $array2[$key]);
                    if (count($recursiveArrayDiff)) {
                        $result[$key] = $recursiveArrayDiff; 
                    }
                    continue;
        }
        else {
            $result[$key] = $value; 
                    continue;
        }
            }
        if (is_object($value)) { 
        if (isset($key, $array2) && is_object($array2[$key])) {
                    $props = array_keys(get_object_vars($value));
                    foreach ($props as $prop) {
                if (isset($array2[$key]->{$prop})) { 
                            if (is_object($value->{$prop}) && is_object($array2[$key]->{$prop})) { 
                                $temp = compare($value->{$prop}, $array2[$key]->{$prop});
                                if (count($temp)) {
                                    $result[$key] = array($prop => $temp); 
                                }
                                    continue;
                                } elseif (is_array($value->{$prop}) && is_array($array2[$key]->{$prop})) { 
                                $temp = compare($value->{$prop}, $array2[$key]->{$prop});
                                if (count($temp)) { 
                                    $result[$key] = array($prop => $temp);
                                }
                                    continue;
                            } else { 
                                if ($value->{$prop} != $array2[$key]->{$prop}) {
                                $result[$key] = array($prop => $value->{$prop}); 
                            }
                            }
                } else {
                $result[$key] = array($prop => $value->{$prop}); 
                }
                        }
                }
        }
            if ($value != $array2[$key]) { 
                $result[$key] = $value; 
            }
        }
        return $result;
    }

正确和错误的输出如下：

//correct output
Array
(
    [c] => stdClass Object
        (
            [d] => Array
                (
                    [2] => 12
                )
            [f] => Hello
        )
)
//wrong output
Array
(
    [c] => stdClass Object
        (
            [d] => Array
                (
                    [1] => 11
                    [2] => 12
                )
            [f] => Hello
        )
)
