After you running your XAMPP, go to your xampp directory then go to htdoc folder. Example : C:\xampp\htdocs. After that create a new folder in the htdocs folder for slim project. I name my folder to slim-framework-rest-api.

Install Composer

If you don have php composer, go to install composer in your computer to download dependency in your project. Go to // You can either install via .exe or type the command in your cmd.

php -r "copy('//', 'composer-setup.php');"
php -r "if (hash_file('SHA384', 'composer-setup.php') === 'e115a8dc7871f15d853148a7fbac7da27d6c0030b848d9b3dc09e2a0388afed865e6a3d6b3c0fad45c48e2b5fc1196ae') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;"

Understanding route

Go to the main slim index file in the slim folder, for example my path is C:\xampp\htdocs\slim-framework-rest-api\vendor\slim\slim\example\index.php. The following will route the index.php to / and /hello/{name}.


$app->get('/', function ($request, $response, $args) {
    $response->write("Welcome to Slim!");
    return $response;

$app->get('/hello[/{name}]', function ($request, $response, $args) {
    $response->write("Hello, " . $args['name']);
    return $response;
})->setArgument('name', 'World!');


RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^ index.php [QSA,L]

Access slim home path

Enter local url in your browser for example : //localhost:63343/htdocs/slim-framework-rest-api/vendor/slim/slim/example/.

If you see error such as the bottom pic.

slim-2You may modify index.php

require 'vendor/autoload.php';

to the full path of autoload.php

require 'C:\xampp\htdocs\slim-framework-rest-api\vendor\autoload.php';

Success access slim

After that, access again the path and you will be see the screen such as below.


You can also try another route for example for my situation //localhost:63343/htdocs/slim-framework-rest-api/vendor/slim/slim/example/hello/questdot

This route specify in the index.php

Edit Virtual Host

Go to the apache\conf\extra path for example my path is C:\xampp\apache\conf\extra to edit the virtual host file configuration which is “httpd-vhosts.conf. Edit and add the following text in your “httpd-vhosts.conf” file to change your project home path. For my case, my home path for the slim project is C:\xampp\htdocs\slim-framework-rest-api\vendor\slim\slim\example.

<VirtualHost *:80>
DocumentRoot “C:/xampp/htdocs/slim-framework-rest-api/vendor/slim/slim/example”
ServerName slimexample

Edit hosts file

Go to edit your hosts file inside the Windows directory C:\Windows\System32\drivers\etc. Right click the hosts file and edit it in the notepad. If you cannot edit the hosts file, drag the hosts file to your desktop and edit it.

Add this line in your hosts file ( slimexample)


Now, you can access by using this path //slimexample/ in your browser.
