Create a Full-stack Blog with vanilla PHP — Intro
Create a Full-stack Blog with vanilla PHP & TailwindCSS for styling.
Brief:
This project focuses heavily on the PHP and the Back-end. The main goal is to enhance our skills and gain a deeper understanding of how things work. In the real world, there are frameworks that handle the job with the support of dedicated teams and communities, ensuring stability and security. Hence, what we create is not advisable for production due to security concerns.
This project was inspired by Laracasts: PHP For Beginners. However, what I'm writing may not be beginner-friendly. I recommend you read it after acquiring a foundational understanding of the basics.

check the changelog to see added/updated features.
Walkthrough:
Considering the project's scope, it will be divided into multiple articles and parts. Each article will have links to facilitate easy navigation and tracking. We will cover fundamental aspects of creating a PHP web app, including database management, routing, request validation, authentication, authorization, middleware, file system handling (uploading), sessions, and more. Additional features may be added in the future as I expand my knowledge.
Prerequisites:
PHP 8 >.
Apache server (XAMPP, MAMP, WAMP, Laragon,...) (I use Laragon).
MySQL Database (You can use whatever Database you are comfortable with).
Setup Environment:
Run Apache & MySQL,
Create a MySQL database, named
vanilla_blog,
create database vanilla_blog;
Folder structure
Feel free to design the file structure according to your preferences, as long as it remains well-organized. The file structure I will use:
- root
- App:
- Configs: **PHP Files that stores the configuration values**
- Controllers: **Route Controller (Like MVC)**
- Core: **The core classes and function**
- Contracts: **Interfaces and abstract classes**
- Middlewares: **Register & Create Middlewares**
- Functions: **Global utility functions**
- Models: **Objects**
- Repositories: **Database Repositories for each model (User, Post,...) to handle Database queries and responses**
- bootstrap.php
- Public: **The public folder**
- JS
- Static: **Store static files like images, logos,...**
- Upload: **Upload directory**
- .htaccess
- index.php: **Entry point**
- routes: **Handel routes**
- web.php: **handle web routes (browser).**
- views: **Handle the page views (Like Laravel MVC, without blade ofc)**
- components: **partials components to include in views**
.htaccess:
The .htaccess files provide users with the ability to configure specific directories on the web server they have control over, without directly modifying the main configuration file. In our case, we can utilize this file to redirect all routes to: index.php, thereby enabling proper routing functionality.
The file's content:
<IfModule mod_rewrite.c>
<IfModule mod_negotiation.c>
Options -MultiViews -Indexes
</IfModule>
RewriteEngine On
# Handle Authorization Header
RewriteCond %{HTTP:Authorization} .
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
# Redirect Trailing Slashes If Not A Folder...
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} (.+)/$
RewriteRule ^ %1 [L,R=301]
# Send Requests To Front Controller...
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^ index.php [L]
</IfModule>
Useful constants
<?php
// ---- BEGIN:CONSTANTS ----
const BASE_PATH = __DIR__ . '/../';
const PUBLIC_PATH = __DIR__;
const HOMEPAGE = "/";
const LOGIN_PAGE = "/auth/login";
const REGISTER_PAGE = "/auth/register";
const PROFILE_PAGE = "/auth/profile";
// ---- END:CONSTANTS ----
Since our entry point is located within the public folder, it is important to ensure that all directory paths are relative to it. To facilitate this, we can use the BASE_PATH constant, which will serve as a reference point for constructing file paths and accessing resources within our project.
Why put an entry point in the public folder:
Let's imagine we have this folder structure:
- root:
- index.php
- router.php
- database.php
If we visit: http://someurl/router.php, we will have direct access to the router.php file, which poses a security vulnerability.
Set public folder as root:
It depends on how you are serving your PHP application. However, if you are using Laragon, you can follow these steps to make the necessary updates: \laragon\etc\apache2\sites-enabled\auto.vanilla-blog.test.conf
Update DocumentRoot from:
DocumentRoot "${ROOT}"
To:
DocumentRoot "${ROOT}/public"
If the file does not exist, create it:
define ROOT "{set the laragon root folder}/laragon/www/vanilla-blog"
define SITE "vanilla-blog.test"
<VirtualHost *:80>
DocumentRoot "${ROOT}/public"
ServerName ${SITE}
ServerAlias *.${SITE}
<Directory "${ROOT}">
AllowOverride All
Require all granted
</Directory>
</VirtualHost>
<VirtualHost *:443>
DocumentRoot "${ROOT}/public"
ServerName ${SITE}
ServerAlias *.${SITE}
<Directory "${ROOT}">
AllowOverride All
Require all granted
</Directory>
SSLEngine on
SSLCertificateFile {set the laragon root folder}/laragon/etc/ssl/laragon.crt
SSLCertificateKeyFile {set the laragon root folder}/laragon/etc/ssl/laragon.key
</VirtualHost>
Useful Utility function:
// app/functions/utils.php
function isUrl($url)
{
return parse_url($_SERVER['REQUEST_URI'])['path'] === $url;
}
function formatDate($date)
{
$formattedDate = date('d/m/Y', strtotime($date));
return $formattedDate;
}
function base_path($path)
{
return BASE_PATH . $path;
}
function public_path($path)
{
return PUBLIC_PATH . $path;
}
function component($name, $data = null) // To require component by its file name (without ".view.php")
{
if ($data != null) {
extract($data);
}
require base_path("views/components/" . str_replace('.', DIRECTORY_SEPARATOR, $name) . '.php');
}
function view($viewName, array $data = []) // To require component by its file name (without ".view.php")
{
extract($data);
$viewName = str_replace(".", DIRECTORY_SEPARATOR, $viewName);
require base_path("views/{$viewName}.view.php");
}
function abort($code)
{
http_response_code($code);
view($code);
die();
}
function config($name) // require confile file by its name
{
return require base_path("app/configs/" . $name . '.php');
}
function dd($value, $json = true) // Dump & die. similar to Laravel

Front-end and style:
To primarily concentrate on the PHP side, I have made the decision to incorporate Tailwind CSS and Flowbite UI. Additionally, I plan to integrate Alpine.js at a later stage.
Partials:
we will need three base components to start with:
Head,
Navigation,
Footer.
Let's create them!
// views/components/head.php
