i am trying to export the data from mysql db into a specific xml format, using php.

i have created like this.

if i do like this, i get proper output of a $string in xml.

<?php
$string = <<<_XML_
<videos>
<updated>2010-07-20T00:00:00Z</updated>
<video>
<id>id</id>
<title>title</title>

</clip>
</clips>
</video>
</videos>
_XML_;

$xml = new SimpleXMLElement($string);

Header('Content-type: text/xml');
echo $xml->asXML();
?>


but if i try to pull values from db and put in the same hierarchy it doesnt output data in xml. like this

<?php
$dbh=mysql_connect($localhost, $username, $password) or die ('I cannot connect to the database because: ' . mysql_error());
$result = mysql_query("SELECT * FROM 12345_flv.flv WHERE enabled = '1' ORDER BY id DESC") or die('Could not connect: ' . mysql_error());

$string = '<<<_XML_<videos><updated>2010-07-20T00:00:00Z</updated><video>';
while ($row = mysql_fetch_array($result)) {
$id=$row['id'];
$title=$row['title'];
$string .='<id>'.$id.'</id>';
$string .='<title>'.$title.'</title>';
}
$string .='</video></videos>_XML_';
$xml = new SimpleXMLElement($string);
Header('Content-type: text/xml');
echo $xml->asXML();
?>


its output shows <<<XML in the page source .

what i am doing wrong.
all i want is export the data from mysql into xml using php.

Answer

Try this code:

<?php
$dbh=mysql_connect($localhost, $username, $password) or die ('I cannot connect to the database because: ' . mysql_error());
$result = mysql_query("SELECT * FROM 12345_flv.flv WHERE enabled = '1' ORDER BY id DESC") or die('Could not connect: ' . mysql_error());  

$string = '<videos><updated>2010-07-20T00:00:00Z</updated><video>';

while ($row = mysql_fetch_array($result)) { 
    $id=$row['id'];
    $title=$row['title'];
    $string .='<id>'.$id.'</id>';
    $string .='<title>'.$title.'</title>';
}
$string .='</video></videos>'; 
$xml = new SimpleXMLElement($string);
Header('Content-type: text/xml');
echo $xml->asXML();
?>
