I've uploaded this file to a webserver but when I go to the address nothing happens

PHP Code:

<?php
if (isset($_COOKIE['admin']))  { 
echo "Welcome Aboard Maytee!
}
else if (isset($_POST['submit'])) {
$connection = mysql_connect('localhost', 'user', 'pass');
$db = mysql_select_db("database");
$username = $_POST["username"];
$password = $_POST["password"];
$result = MYSQL_QUERY("SELECT * from admin WHERE username='$username'and password='$password'")
   or die ("Name and password not found or not matched");
$worked = mysql_fetch_array($result);

$username = $worked[username];
setcookie('admin',$username); 
echo "<META HTTP-EQUIV=Refresh CONTENT='3; URL=$PHP_SELf'>";
}
else {
echo "<form action=$_SERVER['PHP_SELF'] method=POST>
<b>Username:</b> <input type=text name=username size=40><br>
<b>Password:</b><input type=text name=password size=40><br>
<input type=submit name=submit value=Send></form>";
}

replace localhost with mysql server address also replace user with mysql username same as password replace iwth password you have.

also replace database with database you created for example. you created Mydb replace it with Mydb
