how can i make a php script for enter username and password?

Well. There are many solutions.

Here is a very unsecure and stupid (but working) way (one user only):

Code:

<?
session_start();

$usr = $_POST["usr"];
$pwd = $_POST["pwd"];

if ( $usr == "heja" and $pwd == "aik" ) {
$_SESSION["login"] = 1;
}

if ( $_SESSION["login"] != 1 ) {
print "<form method=\"post\"><input name="usr"><input name="pwd"></form>";
exit;
}

?>

Put this in a file and include it in every php-file where you require a password.

I am pretty tired and wrote this just now, so please forgive me for any stupid mistakes. I bet someone can correct this.

well one thing you left out is that it will work only for the user heja and the password aik... if he wants to implement a login form on a public website he will need some sql . Let`s see if i can do do better:
1)db connect file

Code:

$db_user = 'mysql_username';
$db_pass = 'mysql_password';
$db_name = 'mysql_db_name';
$user_name = $_POST['user_name'];
$password = $_POST['password'];

//connect to the DB and select the database
$connection = mysql_connect('localhost', $db_user, $db_pass) or die(mysql_error());
mysql_select_db('db_name', $connection) or die(mysql_error());

save this as let`s say db.php
now the login form:

Code:

<?php
//start the session (unique for each user)
session_start();
//include the file for connecting to the db
include('db.php');

//set up the query
$query = "SELECT * FROM users
      WHERE user_name='$user_name' AND password='$password'";

//run the query and get the number of affected rows
$result = mysql_query($query, $connection) or die('error making query');
$affected_rows = mysql_num_rows($result);

//if there's exactly one result, the user is validated. Otherwise, he's invalid
if($affected_rows == 1) {
   print 'you have logged int';
$_SESSION['user_name'] = $user_name;
}
else {
   print 'user does not exist';
}
?>

I would recommend reading some sessions tutorials...or you could just go to www.evolt.org/article/PHP_Login_Script_with_Remember_Me_Feature/17/60265/
and read there a very good tutorial...but it could be pretty complex if you don`t know nothing about session, cookies, and php functions
Good luck
