加載XML在PHP給錯誤

Question

我試圖加載XML在PHP

$doc = new DOMDocument(); 
$doc->load("LoginVal.xml"); 

我得到一個錯誤

Warning: domdocument::domdocument() expects at least 1 parameter, 0 given in C:\Program Files\Apache Group\Apache2\htdocs\hello.php on line 5

Fatal error: Call to undefined method domdocument::load() in C:\Program Files\Apache Group\Apache2\htdocs\hello.php on line 7

問候， 與Hemant

Answer 1

的致命錯誤是因爲該對象被實例化，警告是因爲它表示期望參數檢查http://us3.php.net/manual/en/domdocument.construct.php

Answer 2

看看here中的評論，這看起來像一個已知的問題（特別是評論＃2）。

Answer 3

顯然在構造函數中有一個parameter missing。嘗試類似

$dom = new DOMDocument('1.0', 'iso-8859-1'); 

Answer 4

請閱讀用戶意見DOMDocument::__construct()。在Windows機器上使用PHP5時（這很可能與您的配置相匹配）有一個關於這個錯誤的討論。我引用christian dot reinecke at web dot de：

[...] make sure you're not overwritting this dom library by another (f.e. extension=php_domxml.dll in php.ini). XAMPP f.e. delivers its standard version with php_domxml.dll which ends up in this error message

確保沒有php_domxml.dll -extension在php.ini。

Answer 5

嘗試完整的文件路徑

此致

$doc = new DOMDocument(); 
$doc->load("LoginVal.xml"); 

嘗試

$doc = new DOMDocument(); 
$doc->load("/path/to/LoginVal.xml");
