本文介绍了一种使用PHP将复杂数组转换为XML格式的方法，通过递归函数arr2xml实现了多级嵌套数组到XML的转换。示例代码展示了如何处理包括字符串、数字及嵌套数组在内的各种数据类型。

php数组转xml的递归实现

原数组

{
    "appid":"wx25d5153f5f7beb451",
    "mch_id":"15422782611",
    "nonce_str":"8b57a6f2307067c8d7fc73db923ba966",
    "device_info":"WEB",
    "body":"奇葩天地网",
    "out_trade_no":"566bb5dadd7049768adf2a43e90f1f72",
    "total_fee":"100",
    "notify_url":"https://pay.qipa250.com/wepay/callback/index",
    "trade_type":"MWEB",
    "openid":"",
    "spbill_create_ip":"127.0.0.1",
    "scene_info":{
        "h5_info":{
            "type":"h5",
            "wap_name":"奇葩天地网",
            "wap_url":"https://www.qipa250.com"
        }
    },
    "sign":"8ED24804982309CC642D769B4EA3A2D7"
}

转换xml

function arr2xml($data, $root = true)
    {
        $str = "";
        if ($root) $str .= "<xml>";
        foreach ($data as $key => $val) {
            if (is_array($val)) {
                $child = self::arr2xml($val, false);
                $str .= "<$key>$child</$key>";
            } else {
                $str .= "<$key>$val</$key>";
            }
        }
        if ($root) $str .= "</xml>";
        return $str;
    }
