Formulaire aide

Bonjour,
a l'aide de internet j'ai reussi a faire tourner un formulaire en php,
ma question est comment refaire ma boucle pourque les données qui rentre apparaisssent au debut de la page et non a la fin de page
merci de votre cooperation.
voici mon code php
<?
$host = '';
$username="";
$password="";
$bdd="";
$table = '';

mysql_connect($host,$username,$password);
mysql_select_db($bdd) or die(mysql_error());


$sql="INSERT INTO $table VALUES('$first','$last','$phone','$mobile','$fax','$email','$web')";

mysql_query($sql) or die(mysql_error());

$query="SELECT * FROM X ";
$result=mysql_query($query);

$num=mysql_numrows($result);

mysql_close();

echo "<b><center>bdd Output</center></b><br><br>";

$i=0;
while ($i > $num) {

$First=mysql_result("First",$i,$result);
$last=mysql_result($result,$i,"last");
$phone=mysql_result($result,$i,"phone");
$mobile=mysql_result($result,$i,"mobile");
$fax=mysql_result($result,$i,"fax");
$email=mysql_result($result,$i,"email");
$web=mysql_result($result,$i,"web");

echo "<b>$first $last</b><br>Phone: $phone<br>Mobile: $mobile<br>Fax: $fax<br>email: $email<br>Web: $web<br><hr><br>";

$i++;
}
