Basic clean url / routing in php

we will make a array to file path. When user visit certain path we will require specific file for specific path.

array of file path

$routes = [
  '' => 'all_file/index.php',
  'about' => 'all_file/about.php',
  'contact' => 'all_file/contact.php'
];

to get url path in php file we extract REQUEST_URI from $_SERVER super global. Trim / from request uri using php trim function. Thats actually sufficient for clean routing. But when we use get method in form we will have some parameter alongside url. So to get only url we are using parse_url function and giving 2nd parameter PHP_URL_PATH.

$path = trim( $_SERVER['REQUEST_URI'], '/' );
$path = parse_url($path, PHP_URL_PATH);

once we have path, we can require a $routes value by path index. Therefore, we have just checked whether this path available or not in our $routes array using array_key_exists. If path is found, we will require file, otherwise we will require not found page. Thats all

if (array_key_exists($path, $routes) ) {
  require $routes[$path];
}else {
  require 'all_file/not_found_page.php';
}

Its working fine in my local php server. But in production we have to tweaking our server for clean url. So I have to make a .htaccess file. which is configuration file for apache web server. and put following content there

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} -s [OR]
RewriteCond %{REQUEST_FILENAME} -l [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^.*$ - [NC,L]
RewriteRule ^.*$ index.php [NC,L]
