获取一个数组的简单方法，该数组包含PHP中嵌套对象中包含的所有整数

<?php
function getAllIntegers($array) {
    $result = [];

    foreach ($array as $item) {
        if (is_array($item)) {
            $result = array_merge($result, getAllIntegers($item));
        } elseif (is_object($item)) {
            $result = array_merge($result, getAllIntegers(get_object_vars($item)));
        } elseif (is_int($item)) {
            $result[] = $item;
        }
    }

    return $result;
}

// 示例使用
$nestedArray = [
    1,
    2,
    [
        3,
        4,
        (object) [
            'property1' => 5,
            'property2' => 6,
            'property3' => [
                7,
                8,
            ]
        ]
    ],
    (object) [
        'property4' => 9,
        'property5' => 10
    ]
];

$integers = getAllIntegers($nestedArray);
print_r($integers);
?>
