PHP generates XML string resolution

PHP generates an XML string
I now have a search result set.
user_id = 1
User_name= Xiao Zhang
Point = 80

USER_ID = 2
User_name= Xiao Li
Point = 60

USER_ID = 3
User_name= Xiao Wang
Point = 70

The string to generate an XML is as follows
"



<> 1 < name="">
<>

2 Xiao Li -


3 Xiao Wang -


";
I ask you how to achieve the hero AH











------Solution--------------------

PHP code

 $xml = << 
   
     xml;while ($row = Mysql_fetch_assoc ($queryResult)) {$xml .=<< 
          
     
     
       {$row [' user_id ']} 
           
     
     
       {$row [' user_name ']} 
      
     
       {$row [' point ']} 
      xml;}
   $xml .=<< 
      
      
      xml;
   
    
------Solution--------------------
    
 Right-click Source code ...
   
    
 want the standard output XML to precede echo with the header (' Content-type:text/xml ');
   
    
------Solution--------------------
    
 That's because the browser parses the XML string as an HTML document, and you can see the full result by looking at the source code. 
    
 precede the code with a header (' Content-type:text/xml; Charset=utf-8 ');, 
    
 and 
    
 $xml = << 
     
     The!--? XML in 
    
 is moved to the front, with no output in front. 
    
 
    
 Everything OK
