There are a few ways you can approach this.
1. If you have access to an LDAP server you can see if the authentication (i.e. password) can be stored on the LDAP server and then follow the tutorial in one of the sections here at phpbuilder.
2. Another way is to use the ACL on your webserver. For example Netscape Enterprise Server 3.5 and iPlanet 4.0 have ACL (Access Control Lists) that limits where and what your users can access. You can let the webserver do most or all of the work.
3. For a PHP-centric solution you can attempt to save username:password combos in a text file readable by only the script (use setuid <-- although that might be dangerous if improperly coded)
4. The best and probably most convenient solution is using PHP with some database such as Microsoft SQL Server or MySQL. You can store the username and passwords in your database and then whenever your user tries to access the site, your PHP script checks to see if they are valid users, if so it sets a session ID on their machine, otherwise it refuses to let them access the site. For session ID tutorials consult the other articles in this forum as well. You can also use cookies should the session ID not work for you.

Hope that helps.

/first check the length of the password ($pass) that the user entered /
if (strlen($pass) >= 6) {

//if length is correct, run query on database
$server = \"localhost\";
$user = \"****\";
$pass = \"***\";
$db = \"val\";
$connection = mysql_connect($server, $user, $pass) or die (\"Unable to connect to database.\");
//pass is the column containing passwords
$query = \"select from val.val where pass=\'$pass\'\";
/ check if there\'s a match between $pass entered and pass from table /
$result = mysql_db_query($db,$query ,$connection);
$num = mysql_numrows($result);
//if there\'s a match
if ($num != \"0\") {
echo \"<table bgcolor=black><tr><td><font color=red><h1>Thank You!<font color=white> \";
echo \"You\'re now logged in\";
}else{
....
You could also use a simple text file, like the user said before. Then OPEN/READ the file and EXPLODE. Then compare strings.
