1. Vorwort / Erklärung:
Erstmal, was hab ich denn hier released: Es handelt sich um einen relativ schlicht gehaltenes Blog-Framework auf MVC (ModelViewController) Basis mit integriertem, kleinem CMS. Das ganze sieht von der View her nicht gerade schön aus – war aber auch nicht der Kern/das Ziel meines Projekts. Im Vordergrund stand die Funktionalität des Ganzen. Außerdem liegt Schönheit bekanntlich im Auge des Betrachters. Ihr könnt es ja mit z. B. Twitter Bootstrap verschönern.

2. Voraussetzungen:
Voraussetzungen gibt es eigentlich nicht viele. Das Ganze ist auf PHP 7 Basis auf einem Apache 2.4 Localhost Server (XAMPP) mit PDO-Unterstützung aufgebaut worden. Ebenso sollte eine Datenbank aufgebaut werden mit dem Namen ‚blog‘ welche drei Tabellen beinhaltet: users, posts und comments.
DB-Name: blog
Tablename: users
- id [int(11), AUTO_INCREMENT, Primary]
- username [varchar(255)]
- password [varchar(225)]
Tablename: posts
- id [int(11), AUTO_INCREMENT, Primary]
- title [varchar(255)]
- content [text]
Tablename: comments
- id [int(11), AUTO_INCREMENT, Primary]
- content [text]
- post_id [int(11)]

4. Codes:
PHP Code:
<?php
spl_autoload_register(function ($class) {
// project-specific namespace prefix
$prefix = 'App\\';
// base directory for the namespace prefix
$base_dir = __DIR__ . '/src/';
// does the class use the namespace prefix?
$len = strlen($prefix);
if (strncmp($prefix, $class, $len) !== 0) {
// no, move to the next registered autoloader
return;
}
// get the relative class name
$relative_class = substr($class, $len);
// replace the namespace prefix with the base directory, replace namespace
// separators with directory separators in the relative class name, append
// with .php
$file = $base_dir . str_replace('\\', '/', $relative_class) . '.php';
// if the file exists, require it
if (file_exists($file)) {
require $file;
}
});

Der Blog ist noch in der „Beta-Phase“. Da kommen noch einige Funktionen dazu. Falls ihr selbst Funktionen dazu wollt, fragt einfach kurz nach und ich schreib sie (ggf. gegen etwas Kleingold) für euch! Hoffe das ganze gefällt euch und ihr findet zurecht. Falls nicht, helfe ich euch gerne per TeamViewer bei der Einrichtung. :) Natürlich findet ihr das ganze Projekt auch zum Download im Anhang ([Only registered and activated users can see links. Click Here To Register...] für die ganzen "Mimimi"-Kiddos).
Greez,
