    Hello World

    - -

    PHP comes with a built in server that helps to speed up - developing by not having to configure a system web server, - first create file index.php;

    - - 
    -        <?php
-           echo "Hello World";
-
    - -

    Now run the server;

    - - 
    -        $ php -S localhost:8000
-
    - -

    Open your browser and browse http://localhost:8000, - you should see "Hello World".

    - -

    Profiling

    - -

    Testing

    - -

    Create folder tests for phpunit files with settings, inside - create another called tests to create tests to be performed on - the code.

    - - 
    -        $ mkdir -p tests/tests
-        $ cd tests
-
    - -

    Create a test tests/EngineTest.php;

    - - 
    -       <?php
-        declare(strict_types=1);
-
-        use PHPUnit\Framework\TestCase;
-
-        final class EngineTest extends TestCase {
-
-            public function testCanBeCreated(){
-
-                   $engine = new engine();
-
-                   $this->assertInstanceOf(engine::class, $engine);
-
-            }
-        }
-
    - -

    Create phpunit.xml;

    - - 
    -       $ phpunit --generate-configuration
-
    - -

    Run the test;

    - - 
    -       $ phpunit
