Remove White Space

Looks like your PHP is putting out a space before the <?xml ...?> declaration, which is technically invalid XML

How do I remove that? This is for Google Maps
<?
require('/fmicdev/geo_search_connect.php');
$center_lat = $_GET["latitude"];
$center_lng = $_GET["longitude"];
$radius = $_GET["radius"];
$connection=mysql_connect (localhost, $username, $password);
if (!$connection) {
  die("Not connected : " . mysql_error());
}
$dom =new DOMDocument("1.0");
$node =$dom->createElement("markers");
$parnode =$dom->appendChild($node);
$db_selected = mysql_select_db($database, $connection);
if (!$db_selected) {
  die ("Can\'t use db : " . mysql_error());
}
$query = sprintf("SELECT concat(street,', ',city,', ',stateprov,', ',zip) AS address, custname, latitude, longitude, ( 3959 * acos( cos( radians('%s') ) * cos( radians( latitude ) ) * cos( radians( longitude ) - radians('%s') ) + sin( radians('%s') ) * sin( radians( latitude ) ) ) ) AS distance FROM dealer HAVING distance < '%s' ORDER BY distance LIMIT 0 , 20", mysql_real_escape_string($center_lat), mysql_real_escape_string($center_lng), mysql_real_escape_string($center_lat), mysql_real_escape_string($radius));
$result = mysql_query($query);
$result = mysql_query($query);
if (!$result) {
  die("Invalid query: " . mysql_error());
}
header("Content-type: application/xml");
while ($row = @mysql_fetch_assoc($result)){
  $node = $dom->createElement("marker");
  $newnode = $parnode->appendChild($node);
  $newnode->setAttribute("name", $row['custname']);
  $newnode->setAttribute("address", $row['address']);
  $newnode->setAttribute("latitude", $row['latitude']);
  $newnode->setAttribute("longitude", $row['longitude']);
  $newnode->setAttribute("distance", $row['distance']);
}
echo $dom->saveXML();
?>

$dom->saveXML() should never have leading or trailing spaces.
What you need to make sure of, is that there is NO space before the first <? tag (line one of your code) and no space, linebreak or anything after the last ?> of your code.
Because PHP will treat any source code not encased in <? ?> as normal html data and output it to the browser/stream.

There are no spaces. Do you have any other thoughts?

It looks like you may have something after the ?>. You have a line 35 that appears blank, so there was most likely something there in your copy / paste.

Please have a look again, cause I'm still getting this error:

if (!$connection) {
  die("Not connected : " . mysql_error());
}
$dom =new DOMDocument("1.0");
$node =$dom->createElement("markers");
$parnode =$dom->appendChild($node);
$db_selected = mysql_select_db($database, $connection);
if (!$db_selected) {
  die ("Can\'t use db : " . mysql_error());
}
$query = sprintf("SELECT concat(street,', ',city,', ',stateprov,', ',zip) AS address, custname, latitude, longitude, ( 3959 * acos( cos( radians('%s') ) * cos( radians( latitude ) ) * cos( radians( longitude ) - radians('%s') ) + sin( radians('%s') ) * sin( radians( latitude ) ) ) ) AS distance FROM dealer HAVING distance < '%s' ORDER BY distance LIMIT 0 , 20", mysql_real_escape_string($center_lat), mysql_real_escape_string($center_lng), mysql_real_escape_string($center_lat), mysql_real_escape_string($radius));

while ($row = @mysql_fetch_assoc($result)){

echo $dom->saveXML();

It appears to be commented out.

There was a space after the ?> in the include file.  It only took me about 8 hours to find it.  Geez.
