我正在生成这些对象来管理扇区中的一组键。

有人可以帮我找到一种方法来执行此代码吗？

是的，您已经嵌套了数组，但 htmlspecialchars 需要字符串。

在来自https://gist.github.com/igorw/7628042 的递归array_map 下方，可以将htmlspecialchars 应用于嵌套数组。

function array_map_recursive($f, $xs) {
    $out = [];
    foreach ($xs as $k => $x) {
        $out[$k] = (is_array($x)) ? array_map_recursive($f, $x) : $f($x);
    }
    return $out;
}

$data = [
    'foo' => [
        'bar' => [
            'baz' => [
                'lorem ipsum'
            ]
        ]
    ]
];

print_r(array_map_recursive('htmlspecialchars', $data));
