for one, at the very top:  <?php instead of <php?
Also, echo is not a function that uses () as far as I know, it's 

echo "This will be printed";

[silentg0d]

no <php? is rite becuz when i change it to <?php it errors the whole page

[silentg0d]

i changed <php? to <?php and i get this error
Parse error: syntax error, unexpected '{' in /home/xploit/public_html/home/index.php on line 91

which would be this line

<?php if( !isset( $_POST['submit'] ) )
{

echo( '<form action="' . $_SERVER['PHP_SELF'] . '" method="post">
Username: <input type="text" name="username" /><br />
Password: <input type="password" name="password" /><br />
<input type="submit" name="submit" value="Login" />' );

} else {

if( $file_exists( 'users.db' )
>>>>>>>>>>>>>>>>>>>>>>>>>>>{

$file = file( 'users.db' );

foreach( $file as $info )
{

$explode = explode( '|', $info );
$user = $explode[0];
$pass = $explode[1];
$email = $explode[2];
$usern = $_POST['username'];
$passw = $_POST['password'];
if( ( $usern == $user ) && ( $passw == $pass ) )
{
echo( 'Members Area' );
}
}

} else {

$fopen = fopen( 'users.db', 'w+' )
fwrite( $fopen, '' );
fclose( $fopen );
}
?>

This should work:
[code]
<?php
if(!isset( $_POST['submit'])) {
echo( '<form action="bbb.php" method="post">
Username: <input type="text" name="username" /><br />
Password: <input type="password" name="password" /><br />
<input type="submit" name="submit" value="Login" />' );
}
if(file_exists('users.db' )){
$file = file( 'users.db' );
foreach( $file as $info ) {
$explode = explode( '|', $info );
$user = $explode[0];
$pass = $explode[1];
$email = $explode[2];
$usern = $_POST['username'];
$passw = $_POST['password'];
if( ( $usern == $user ) && ( $passw == $pass ) ){
echo( 'Members Area' );
}
}
}
else{
$fp = fopen ("users.db", "w+");
fwrite ($fp, "");
fclose ($fp);
}
?>
[/code]

You might want to try formatting the code so its easily readable. Also pointing out which lines are throwing errors helps us to debug, better yet, maybe learn to debug yourself.

[code=php:0]
<?php

  if (!isset( $_POST['submit'])) {
    echo '<form action="bbb.php" method="post">
    Username: <input type="text" name="username" /><br />
    Password: <input type="password" name="password" /><br />
    <input type="submit" name="submit" value="Login" />';
  }
  if (file_exists('users.db')) {
    $file = file('users.db');
    foreach ($file as $info) {
      $explode = explode('|',$info);
      $user = $explode[0];
      $pass = $explode[1];
      $email = $explode[2];
      $usern = $_POST['username'];
      $passw = $_POST['password'];
      if (($usern == $user) && ($passw == $pass)) {
        echo( 'Members Area' );
      }
    }
  } else {
    $fp = fopen ("users.db", "w+");
    fwrite ($fp, "");
    fclose ($fp);
  }
?>
[/code]

As far as I can tell there are no syntax erros in the above code. The logic of it however is pretty out there. You really should have a call to exit() after echo( 'Members Area' );.

ty and i would debug it myself but im just learning php, my friend made this for me and hes rarely on..

[silentg0d]

im sorry to be a pain but you last debug seemed to have worked somewhat it fixed the code sortove but i still get

The code i sent you WORKS!(i checked it),but it is obviously just part of some script,and the problem is not in this part-problem is somewhere else.
If you get permission denied message change folder permissions to 777.

ive resolved this  i had to change <form action="bbb.php" or whatever you put init to <form action="' . $_SERVER['PHP_SELF'] . '" plz lock
