Here’s a PHP Login System, based on the one developed by jpmaster77: PHP Login System with Admin Features
Focusing only on the core functionalities and aimed to improve certain parts of the code, I took out some functionalities and added some others:
Removed:

• Admin features
• Active guests, active users, banned users
• Global variables
• Links to other pages after the login

All these can be easily reintegrated if you want. I focused on the login and registration part, leaving out the content “inside”.
Added:

• PHP 5 instead of PHP 4
• mysqli extension
• Send registration confirmation link to the email address
• Reset password feature without sending password to the email. Instead a link is sent to reset the password
• UTF8 support
• InnoDB transactions for database operations
• Registration and form validations made with AJAX
• jQuery
• Captcha image in registration form to avoid spam

Here are the most important settings for the installation of the login system.
Set database access in constants.php:

define("DB_SERVER", "localhost"); //type mysql server url
define("DB_USER", "XXXXXXX");  //type mysql user
define("DB_PASS", "XXXXXXX");  //type mysql password
define("DB_NAME", "XXXXXXX");  //type mysql database name

Further, you have to set the right location of the following files for the mail sending functions:

define("RESETPASSWORDLINK","http://www.tympanus.net/loginsystem/resetpassword.php");
define("CONFIRMACCOUNTLINK","http://www.tympanus.net/loginsystem/php/confirm.php");

The only table that you have to create in your MySQL database is the following:

CREATE TABLE users(
pk_user int unsigned not null auto_increment,
email  varchar(120) not null,
flname varchar(100) not null,
password varchar(64) not null,
usr_signup_date timestamp not null default CURRENT_TIMESTAMP,
usr_userid varchar(32),
# for the account confirmation:
usr_confirm_hash varchar(255) not null,
# after confirming its set to 1:
usr_is_confirmed tinyint(1) not null default 0,
# when the user resets password (forgot password):
usr_resetpassword_hash varchar(255) not null,
unique index(email),
primary key(pk_user)
)type=innodb DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci;

I will soon post a new version, as I am currently improving some points.
