How to stop PHP from generating blank line for first character of XML?

[brian mccallum]

My PHP code is generating XML with a blank first line before the <?xml version="1.0" ?>

see http://urbanbees.co.uk/maps/phpsqlajax_genxml3.php

I have been told this is the reason why my map is not showing the markers in chrome and FF but it is OK in IE8. see http://urbanbees.co.uk/maps/map_of_h...ons_update.htm You'll either see markers or not depending on your broswer.

How do I change the code to not generate this first blank line.

Here is the php code.

<?php
require("phpsqlajax_dbinfo.php");
// Start XML file, create parent node
$dom = new DOMDocument("1.0");
$node = $dom->createElement("markers");
$parnode = $dom->appendChild($node);
// 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 (!$result) {   
  die('Invalid query: ' . mysql_error()); 
}  
header("Content-type: text/xml");  
// Iterate through the rows, adding XML nodes for each 
while ($row = @mysql_fetch_assoc($result)){   
  // ADD TO XML DOCUMENT NODE   
  $node = $dom->createElement("marker");   
  $newnode = $parnode->appendChild($node);    
  $newnode->setAttribute("name",$row['name']); 
  $newnode->setAttribute("address", $row['address']);   
  $newnode->setAttribute("lat", $row['lat']);   
  $newnode->setAttribute("lng", $row['lng']);   
  $newnode->setAttribute("type", $row['type']); 
}  
echo $dom->saveXML();
?>

I have found the problem. There was a space after the end of the php code in 'phpsqlajax_dbi nfo.php' which was called from the above code. Taking away the space after the ?> solved the issue.
