Im making a login script with sessions, and when i logged in i recieved a message

Warning: Unknown: Your script possibly relies on a session side-effect which existed until PHP 4.2.3. Please be advised that the session extension does not consider global variables as a source of data, unless register_globals is enabled. You can disable this functionality and this warning by setting session.bug_compat_42 or session.bug_compat_warn to off, respectively. in Unknown on line 0

 

I dont really know what that is and how to fix it can someone explain to me on how to fix that

here is my script for logging in

<?php
$username = $_POST['username'];
$password = $_POST['password'];
if( (empty($username)) || (empty($password)) ) {
	print("<p>Please fill in all fields to continue</p>");
} else {
	$password = md5($password);
	$query = "SELECT username FROM ph_users WHERE username = '$username' AND password = '$password'";
	$result = mysql_query($query) or die("<p>Please Try Again</p>");
		$row = mysql_fetch_row($result);
		if($row > 1) {
			session_start();
			session_register('username');
			print("<p>Thank you for logging in</p>");
		} else {
			print("<p>Please Try Again</p>");
		}
}
?>
<form action="<?php $_SERVER['PHP_SELF']; ?>" method="POST">
<label>Your UserName:</label><br><input type="text" size="30" name="username"><br><br>
<label>Your Password:</label><br><input type="password" size="30" name="password"><br><br>
<input type="submit" name="login" value="Login to your Account">
</form>

Replace this line:

session_register('username');

 

with:

$_SESSION['username'] = "Value";

 

That *might* get rid of the error. Your registering your session the deprecated way.

[perezf]

how does this work

$_SESSION['username'] = "Value";

what does Value stand for

[pocobueno1388]

Well, you have to give the session a value. I'm guessing the value would be the users username...If you don't want to assign a value to it, just do this:

 

$_SESSION['username'] = TRUE;

 

The value of the session is what would be displayed if you echoed it out.
