 <p><code>PHPrunner</code> uses inbuilt server to preview your generated application. So quite obvious when you close Runner it will close the inbuilt server connection as well. You will have to move the <code>output</code> folder to <code>root folder</code> of your web server. If you look inside your project folder, you will find a folder named <code>output</code>, move this folder to the <code>root folder</code> of your web server, it should work fine.</p> <p>Make sure your web server is powered to use PHP and other drivers related to your project.</p>
