WebMatrix PHP mySQL

I am using WebMatrix Beta 3 which has support for php 5.2 and 5.3 I am able to run php pages but when I am trying to connect to mySql DB its not working.

Can anyone please suggest me the right way of doing it.

The connection code is written in a file called dbinfo.php which resides under config folder

<?php
$hostname = '127.0.0.1';
$username = 'root';
$password = 'password';
$database = 'test';

$link = mysql_connect($hostname, $username, $password)
  or die("Could not connect : " . mysql_error());
mysql_select_db($database) or die("Could not select database");

//Below function added to allow customized unescaping.
function mysql_unescape($sRet_VAL=""){
  $sRet_VAL = str_replace('\"','"',$sRet_VAL);
  $sRet_VAL = str_replace("\'","'",$sRet_VAL);
return $sRet_VAL;
}
?>

and I am using this file as follows

<?php
require_once( $_SERVER['DOCUMENT_ROOT'] . '/config/dbinfo.php');
?>
<?php

    $query = "SELECT * from temp";
    $result = mysql_query($query)
        or die("Error: " . mysql_error());
?>

it worked seems like webmatrix do not recognize I replaced it wilt <>php echo $varData ?> and it worked.
