A little tip for php-xml-dom

Today,I tried to create a xml file by php, I used dom to create the xml file,but I found that the application can output xml file,but can not made it in correct and expect format.

I searched by google,but little useful points,I tried something,I found one easy and good tip,
Some codes are as follows:

header(’Content-Type:text/xml’);
$guestbook = new DomDocument();
$guestbook->formatOutput = true;

the bold codes are the main point,pls note it.

Hope it can helpe some one who met this problem.

Try it!
