problem with php/mysql installation

Hi

I am new to php and trying to setup my dev environment. I have followed the
documentation to install WAMP but unable to get php work with mysql.

My env details are:
 Operating system : Windows 7
 PHP version: 5.2.17
 Web server : Apache 2.2
 MySQL 5.1.56

* Running PHP as Apache module

Problem Description: http://localhost/test.php  *[ <?php phpinfo(); ?> ] * is
correctly showing me php details in the html page. It also shows mySQL and
mySqli in its tabular form.
I believe this conforms that php is set up properly.

To test mysql access from php, i am using following php script: ( I have
created a database "test" from mysql command line)

<?php

# Define MySQL Settings
define("MYSQL_HOST", "localhost");
define("MYSQL_USER", "root");
define("MYSQL_PASS", "password");
define("MYSQL_DB", "test");

$conn = mysql_connect("".MYSQL_HOST."", "".MYSQL_USER."", "".MYSQL_PASS."")
or die(mysql_error());
mysql_select_db("".MYSQL_DB."",$conn) or die(mysql_error());

$sql = "SELECT * FROM test";
$res = mysql_query($sql);

while ($field = mysql_fetch_array($res))
{
$id = $field['id'];
$name = $field['name'];

echo 'ID: ' . $field['id'] . '<br />';
echo 'Name: ' . $field['name'] . '<br /><br />';
}

?>

When I try to run this script http://localhost/mysql_test, it dumps me to
error page:
* The webpage at http://localhost/mysql_test.php might be temporarily down
or it may have moved permanently to a new web address*

I confirmed that mysql is running as a service, apache is running as a
service. In apache log here is what i see:

I have been trying all possible solution to make this work, I will
appreciate if you can guide me toward the right solution.
