/**
|
|
* A simple, clean and secure PHP Login Script
|
|
*
|
|
* MINIMAL VERSION
|
|
* (check the website / github / facebook for other versions)
|
|
*
|
|
* A simple PHP Login Script.
|
|
* Uses PHP SESSIONS, modern password-hashing and salting
|
|
* and gives the basic functions a proper login system needs.
|
|
*
|
|
* Please remember: this is just the minimal version of the login script, so if you need a more
|
|
* advanced version, have a look on the github repo. there are / will be better versions, including
|
|
* more functions and/or much more complex code / file structure. buzzwords: MVC, dependency injected,
|
|
* one shared database connection, PDO, prepared statements, PSR-0/1/2 and documented in phpDocumentor style
|
