XML Parsing Error: junk after document element. Google maps database interaction - php

Question

Hi so I'm trying to pull data from a database to be used with Google Maps following the advice from a Google developers article: https://developers.google.com/maps/articles/phpsqlajax_v3. I have copied their exact code in an attempt to just get a start before manipulating it but it keeps throwing the following error: XML Parsing Error:
junk after document element
Location: http://localhost/Google/phpsqlajax_xml3.php
Line Number 2, Column 1:
^
I know the same error has been posted before, but I'm yet to find a solution that works for me. Any advice is appreciated! Here's my code, straight from google:
<?php
//require("phpsqlajax_dbinfo.php");
$username="root";
$password="";
$database="my_db";
function parseToXML($htmlStr)
{
$xmlStr=str_replace('<','<',$htmlStr);
$xmlStr=str_replace('>','>',$xmlStr);
$xmlStr=str_replace('"','"',$xmlStr);
$xmlStr=str_replace("'",''',$xmlStr);
$xmlStr=str_replace("&",'&',$xmlStr);
return $xmlStr;
}
// Opens a connection to a MySQL server
$connection=mysql_connect('localhost', $username, $password);
if (!$connection) {
die('Not connected : ' . mysql_error());
}
// Set the active MySQL database
$db_selected = mysql_select_db($database, $connection);
if (!$db_selected) {
die ('Can\'t use db : ' . mysql_error());
}
// Select all the rows in the markers table
$query = "SELECT * FROM markers WHERE 1";
$result = mysql_query($query);
if (!$result) {
die('Invalid query: ' . mysql_error());
}
header("Content-type: text/xml");
// Start XML file, echo parent node
echo '<markers>';
// Iterate through the rows, printing XML nodes for each
while ($row = #mysql_fetch_assoc($result)){
// ADD TO XML DOCUMENT NODE
echo '<marker ';
echo 'name="' . parseToXML($row['name']) . '" ';
echo 'address="' . parseToXML($row['address']) . '" ';
echo 'lat="' . $row['lat'] . '" ';
echo 'lng="' . $row['lng'] . '" ';
echo 'type="' . $row['type'] . '" ';
echo '/>';
}
// End XML file
echo '</markers>';
?>

Just in case anyone else is stuck with a similar issue it was resolved by changing all the mysql statements to their mysqli equivalent.
