Using the code

You need to give 777 -R permissions to your project folder.

Install composer:

curl -s https://getcomposer.org/installer | php

Install via composer:

composer install

php composer.phar install

You also need to register Slim’s autoloader.

require 'Slim/Slim.php';

Make sure you required Slim.php file that belongs to in Slim folder. Otherwise you won't be able to use Slim framework.

Then invoke this static registerAutoloader() function define into the Slim class. It is necessary to registerAutoloader() function if you won't register nothing will be work.

\Slim\Slim::registerAutoloader();

The next step would be just need to instantiate the \Slim\Slim() class and use referrence as an object, use that object in our code.

$application = new \Slim\Slim();

Define a HTTP GET route:

$application->get(
'/hi/:firstname/:lastname',
function ($first,$last){
echo "Hi!! $first $last";
});

'/hi/:firstname/:lastname' is the URL. If this URL is match then following function will be invoked using GET HTTP method.

function ($first,$last){
echo "Hi!! $first $last";
});

Run the your Slim application:

$application->run();

The URL address like

http://localhost/slimsample/helloslim.php/hello/Bryan/Adams

helloslim.php is my Slim application page.

hi/Bryan/Adams append with the URL address if it would be match to hi/:firstname/:lastname and if it's available the generate the output using passing parameters $first and $last.

Output is,

Hi!! Bryan Adams
