PHP DOM generated XML break line [duplicate]

PHP XML how to output nice format

I have the following PHP DOM code that creates a XML document in a dynamic way:

<?php // create doctype $dom = new DOMDocument("1.0"); // display document in browser as plain text // for readability purposes header("Content-Type: text/plain"); for ($i=1;$i<=5;$i++) { // create root element $root = $dom->createElement("toppings"); $dom->appendChild($root); // create child element $item = $dom->createElement("item"); $root->appendChild($item); // create text node $text = $dom->createTextNode("pepperoni"); $item->appendChild($text); } // save and display tree echo $dom->saveXML(); ?>

The PHP code generates the next XML code:

<?xml version="1.0"?> <toppings><item>pepperoni</item></toppings> <toppings><item>pepperoni</item></toppings> <toppings><item>pepperoni</item></toppings> <toppings><item>pepperoni</item></toppings> <toppings><item>pepperoni</item></toppings>

I would like to know what to change in order for the XML look like this other way:

<?xml version="1.0"?> <toppings> <item>pepperoni</item> </toppings> <toppings> <item>pepperoni</item> </toppings> <toppings> <item>pepperoni</item> </toppings> <toppings> <item>pepperoni</item> </toppings> <toppings> <item>pepperoni</item> </toppings>

Minor sidenote; especially with PHP scripts that output something, be careful of the closing '?>'. It can cause an empty line at the end of your output that can bork up other scripts. — Nathaniel Ford

Try $dom->formatOutput = true.
