我從災害中心接到資料可以存到mysql
可是從裡面要找出 areaDesc
卻不行
以下是我的程式碼:
(第一行收到以下XML資料)

以下是資料庫收到的東西(存$xmldata的值)

你知道 xml 可以貼在程式碼區塊嗎? 不然想幫你的人還得手動輸入 xml 也太辛苦了

我發現是因為中文無法被正確讀取，會出現亂碼，可是使用utf8還是有問題

找錯層了…
其他的以此類推…

 ["info"]=>
  array(2) {
    [0]=>
    object(SimpleXMLElement)#2 (17) {
      ["language"]=>
      string(5) "zh-TW"
      ["area"]=>
      array(16) {
        [0]=>
        object(SimpleXMLElement)#9 (2) {
          ["areaDesc"]=>
          string(18) "臺東縣綠島鄉"
          ["geocode"]=>
          object(SimpleXMLElement)#25 (2) {
            ["valueName"]=>
            string(18) "Taiwan_Geocode_103"
            ["value"]=>
            string(7) "1001411"
          }
        }
        [1]=>
        object(SimpleXMLElement)#10 (2) {
          ["areaDesc"]=>
          string(21) "臺東縣太麻里鄉"
          ["geocode"]=>
          object(SimpleXMLElement)#25 (2) {
            ["valueName"]=>
            string(18) "Taiwan_Geocode_103"
            ["value"]=>
            string(7) "1001409"
          }
        }

PHP：

$data->info[0]->area;

結果：

object(SimpleXMLElement)#2 (2) {
  ["areaDesc"]=>
  string(18) "臺東縣綠島鄉"
  ["geocode"]=>
  object(SimpleXMLElement)#3 (2) {
    ["valueName"]=>
    string(18) "Taiwan_Geocode_103"
    ["value"]=>
    string(7) "1001411"
  }
}
