auto_increment, and that's what seemed to solve my issue. Looks like a
simple omission in forgetting to use auto_increment and using primary key.
I usually know better. I'll blame this one on the clonopin. lol
thank you

Hello fellows,
Does any one know a good guide for noobs to compile last PHP with
Apache support from source code? I was planning to use Ubuntu 11.10.
Already googled it but could only find old references that cannot be
used anymore.
Thanks.

Hello Alan.
Did you ever compile any application?
It's relatively simple. Generaly, You just have to:
Certify you have the minimum tools to compile a program (e.g apt-get install
build-essentials)
Cd to the php sources directory (i'm assuming you have allready downloaded them)
As root, run:
# ./configure
Select the options that applies to your needs, them
# make && make install
That should do the trick for you

I'm currently learning php and as a challenge, I'm creating a login
script using text files to store the information (until I learn how to
handle databases with php).
The problem I'm having is the if statement in my while loop is only
evaluated on the last iteration of the while loop, so its only
comparing the last username in the file and no others.
Heres the code:
<?php
session_start();
$users = file("../inc/users.inc.php");
if($_POST['username'] && $_POST['password']){
if(ereg("^[^@ ]+@[^@ ]+\.[^@ \.]+$",
$_POST['username'])){
while(list($id ,$username) = each($users)){
if($_POST['username'] == $username){
$_SESSION['logged_in'] = 1;
$_SESSION['username'] =
$username;
}
}
if($_SESSION['logged_in'] != 1){
$error = "2";
}
}else{
$error = "4";
}
}else{
$error = "3";
}
if($error){
header("Location:
http://koopasforever.com/scripts/login.php?error=$error";);
}else{
header("Location: http://koopasforever.com/";);
}
?>
I have checked all my variables and they all contain the proper information
Some help would be greatly appriciated, Thanks
