Login script, need help.

[Anon]

Ok, I don't have access to an SQL server and i really don't want to because of my needs are so small. So I wrote a login script without using a database, but using a text file for the 'database'. It seems no matter what I do it just wont work, constantly having probs. I havn't worked with PHP all that much 5 days, but I know the basics. Well heres the code.

---

<?
$filename = "passwordfile.php";
$passwords = fopen ($filename, "r");

$username = $session_username;
$password = $session_password;

function CheckUser($session_username,$session_password,$passwords) {
if ($passwords == "$session_username:$session_password")
return "allowed";
else if ($passwords != "$session_username:$session_password")
return "denied";
}

if (CheckUser() == "allowed") {
header ("Location: main.php");
}
else if (CheckUser() == "denied") {
echo("<h1>Error!</h1>");
echo("<br><h3>Your username and password are incorrect</h3>");
echo("<br><h3><a href=password_enter.html>Please click here to try again.</a></h3>");
}

?>

I have a HTML form sending the variables $username and $password to this. And the problem im getting is taht it can't find the variables in the function CheckUser().

Please help.

You could try using strcmp(..) for comparing two strings (http://www.php.net/manual/en/function.strcmp.php)

you are opening the file, but not getting any text from it. that is the first problem i can see...

Here's another problem:

function CheckUser($session_username,$session_password,$passwords) { .. }
...
if (CheckUser()...

I.e., you aren't actually passing any parameters to the function.

Ok, well i looked at your messages and when one of you siad that its not reading the file i did a simple script

$filename = "passwordfile.php";
$passwords = fopen ($filename, "r");

echo("$passwords");

and found that it wasn't saying what it was so i found out how to do it and everything is sloved!

Thanks for your help!
