PHP save file on IE Vista, adding newlines - php

Question

I tried this to format the XML output in a PHP function with the formatoutput = true and that didn't do it. So I want to do this with a function. I found two different scripts for that but they all have the same issue: they do the indentation but the newline "\n" doesn't print in the file. Is there a different way to get the newline?
PHP script
<?php
ini_set('display_errors', 1);
error_reporting(E_ALL);
function make_update( $nodeid, $name, $top, $left, $width, $height ) {
$nodes = new SimpleXMLElement('linkcards.xml', null, true);
$returnArray = $nodes->xpath("//LINKCARD[#ID='$nodeid']");
$node = $returnArray[0];
$node->NAME = $name;
$node->TOP = $top;
$node->LEFT = $left;
$node->WIDTH = $width;
$node->HEIGHT = $height;
$nodes->asXML('linkcards.xml');
$formatted = formatXmlString($nodes->asXML());
$file = fopen ('linkcards.xml', "w");
fwrite($file, $formatted);
fclose ($file);
}
echo make_update(trim($_REQUEST['nodeid']),trim($_REQUEST['name']),trim($_REQUEST['top']),trim($_REQUEST['left']),trim($_REQUEST['width']),trim($_REQUEST['height']));
function formatXmlString($xml) {
// add marker linefeeds to aid the pretty-tokeniser (adds a linefeed between all tag-end boundaries)
$xml = preg_replace('/(>)(<)(\/*)/', "$1\n$2$3", $xml);
// now indent the tags
$token = strtok($xml, "\n");
$result = ''; // holds formatted version as it is built
$pad = 0; // initial indent
$matches = array(); // returns from preg_matches()
// scan each line and adjust indent based on opening/closing tags
while ($token !== false) :
// test for the various tag states
// 1. open and closing tags on same line - no change
if (preg_match('/.+<\/\w[^>]*>$/', $token, $matches)) :
$indent=0;
// 2. closing tag - outdent now
elseif (preg_match('/^<\/\w/', $token, $matches)) :
$pad--;
// 3. opening tag - don't pad this one, only subsequent tags
elseif (preg_match('/^<\w[^>]*[^\/]>.*$/', $token, $matches)) :
$indent=1;
// 4. no indentation needed
else :
$indent = 0;
endif;
// pad the line with the required number of leading spaces
$line = str_pad($token, strlen($token)+$pad, ' ', STR_PAD_LEFT);
$result .= $line . "\n"; // add to the cumulative result, with linefeed
$token = strtok("\n"); // get the next token
$pad += $indent; // update the pad size for subsequent lines
endwhile;
return $result;
}
?>

Found the answer. If I write "\r\n" for the newline, it works!!!!!!
$result .= $line . "\r\n";
Using that function instead of formatoutput = true might be a useful workaround for anyone else who had trouble formatting the XML output.
