This is the php code where I want to generate an XML from the queries in MySQL:
<?php
header('Content-type: text/xml');
$xmlout = "<?xml version=\"1.0\" ?>\n";
$xmlout .= "<persons>\n";
$db = new PDO('mysql:host=xxxx;dbname=xxxx','xxxx','xxxx');
$stmt = $db->prepare("select * from wp_cf7dbplugin_submits");
$stmt->execute();
while($row = $stmt->fetch()){
$xmlout .= "\t<person>\n";
$xmlout .= "\t\t<rut>".$row['rut']."</rut>\n";
$xmlout .= "\t\t<nombre>".$row['nombre']."</nombre>\n";
$xmlout .= "\t\t<apellido>".$row['apellido']."</apellido>\n";
$xmlout .= "\t\t<correo>".$row['correo']."</correo>\n";
$xmlout .= "\t\t<telefonomovil>".$row['telefonomovil']."</telefonomovil>\n";
$xmlout .= "\t\t<carrera>".$row['carrera']."</carrera>\n";
$xmlout .= "\t</person>\n";
}
$xmlout .= "</persons>";
echo $xmlout;
?> 
When I execute it, it gives me the following message:
This page contains the following errors:
error on line 115 at column 11: Extra content at the end of the document Below is a rendering of the page up to the first error.
What could it be?
