Getting XML file content as string in php -

I want to display the contents of an XML file as my own. I do not want to parse it, instead read its content and display it.

I tried

  $ content = file_get_contents ("test.xml");   
 But there is xml in  $ content . When I have the  var_dump ($ content)  output  string (899) ""  is it possible to read without a corresponding file. Please help me  
 Thank you.   
 
 
 it should be resolved  
  $ content = htmlentities (file_get_contents ( "Test.xml"));   
 and should resolve it:  
  header ("content-type: text / plain"); $ Content = file_get_contents ("test.xml"); Var_dump ($ content);   
 This tells the browser sending plain text to you so that XML is not provided as HTML tags (which is then unknown and hidden).
