simplexml_load_string XML錯誤

Question

我是testingsimplexml_load_string（）函數。

<?php 
ini_set('display_errors', '1'); 
$test = stripslashes($_POST['xml']); 
$testing = simplexml_load_string($test); 
print_r($testing); 
?> 

執行以下錯誤發生後，即使我是條紋斜線。

Warning: simplexml_load_string(): Entity: line 1: parser error : Malformed declaration expecting version in /var/www/check.php on line 5 

Warning: simplexml_load_string(): <?xml encoding='utf8'?><!DOCTYPE a[<!ENTITY e SYSTEM '/etc/passwd'>]><a>&e;</a> in /var/www/check.php on line 5

我該如何解決這個錯誤？

我認爲你正在嘗試轉換的xml文件格式不正確。您可以嘗試第一個示例中官方文檔here中的示例，然後嘗試使您的XML文件適合這種情況。
