A simple, but secure PHP login script. Uses the ultra-modern & future-proof PHP 5.5 BLOWFISH hashing/salting functions (includes the official PHP 5.3 & PHP 5.4 compatibility pack, which makes those functions available in these versions too).
In the PHP world every beginner tries to build login systems from scratch, doing all the typical mistakes, usually going from saving plain text passwords to using (horribly wrong) MD5 hashing. This script tries to give beginners a usable code base with a fully implemented user authentication ("login") system, preventing less-experienced developers at least from the worst security issues.
This script was originally part of the "php-login project", a collection of 4 different login scripts made in the 2012-2013 PHP era to give especially beginners and security-inexperienced users a set of basic auth functions that fitted the most modern password hashing standards possible. You know, this was the time when even major companies like SONY and LinkedIn used horrible outdated MD5-hashing for their passwords (or even saved everything in plain text) and when the big PHP frameworks didn't have proper user auth solution out-of-the-box.

- PHP 5.3.7+
- MySQL 5 database (please use a modern version of MySQL (5.5, 5.6, 5.7) as very old versions have a exotic bug that makes PDO injections possible.
- activated mysqli (last letter is an "i") extension (activated by default on most server setups)
Create a database login and the table users via the SQL statements in the _install folder.
Change mySQL database user and password in config/db.php (DB_USER and DB_PASS).

This script comes with a handy .htaccess in the views folder that denies direct access to the files within the folder
(so that people cannot render the views directly). However, these .htaccess files only work if you have set
AllowOverride to All in your apache vhost configs. There are lots of tutorials on the web on how to do this.
