$filename = "data.txt";
$fp = fopen( "data.txt", 'r' );
$file_contents = fread( $fp, filesize( $filename ) );
fclose( $fp );
// Place the individual lines from the file contents into an array.
$lines = explode ( "\n", $file_contents );
$memb=count($lines);
// Split each of the lines into a username and a password pair
// and attempt to match them to $PHP_AUTH_USER and $PHP_AUTH_PW.
foreach ( $lines as $line ) {
if ($line) {
list( $user, $pass ) = explode( '->', $line );
}
if (($user == $username)&&($pass == $password)) {
// A match is found, meaning the user is authenticated.
// Stop the search.

The problem in here is when enter the correct username and password, i can't get in. so i change this line in readform:
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
if (($user == $username)&&($pass == $password))
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
TO
if ($user == $username)
then it works, and i do the samething for the password, then it doesn't work.
that means i can validate the username, but the password can't.
