我已經調試了一個小小的開源php腳本並且發現了這個錯誤信息有人請給我一些解釋什麼它有錯嗎？注意：未定義的索引：NAME在C： xampp htdocs Inventory lib config.php上線108

提前

這裏非常感謝是被提到的一點：

function HNDCData($parser,$cdata) { 
     $cdata = str_replace("[amp]","&",$cdata); 
     //echo "<br>" . $cdata; 
     // create the proper tree node if NAME attribute is set 
     if ($this->attr["NAME"] != "") 
      $this->tags[count($this->tags) - 1] = $this->attr["NAME"];

和完整的PHP文件：

'$ this-> attr'沒有''NAME''屬性。 –

您可以嘗試查找變量attr的定義位置。你可以在父類CXMLParser中找到它 – Yang

變化：

if ($this->attr["NAME"] != "")

要：

if (isset($this->attr["NAME"]) && $this->attr["NAME"] != "")
