This is a very simple Script for the beginners.

$host=”localhost”; // Host name
$username=”root”; // Mysql username
$password=”"; // Mysql password
$db_name=”dbname”; // Database name
$tbl_name=”table_name”; // Table name

// Connect to server and select databse.
mysql_connect(“$host”, “$username”, “$password”)or die(“cannot connect”);
mysql_select_db(“$db_name”)or die(“cannot select DB”);

// username and password sent from form
$myusername=$_POST['myusername'];
$mypassword=$_POST['mypassword'];

$sql=”SELECT * FROM $tbl_name WHERE uname=’$myusername’ and pswd=’$mypassword’”;
$result=mysql_query($sql);

// Mysql_num_row is counting table row
$count=mysql_num_rows($result);
// If result matched $myusername and $mypassword, table row must be 1 row

if($count==1){
// Register $myusername, $mypassword and redirect to file “login_success.php”
session_register(“myusername”);
session_register(“mypassword”);
header(“location:login_success.php”);
}
else {
echo “Wrong Username or Password”;
}
?>
