How to install Magento 2 Module/Extension without cmd only External php file

How to run cmd command using magento 2 url not use command prompt. Create a php file on you magento 2 root directory & just run localhost/file.php or domain/php_file_name.php
In the code line number 14 you can add your magento 2 command here. After running the php file it take some time to executing the total procedure. Note it: if you use content static deploy, it takes long time & some time its failed cause of different issue. Make sure you have unlimited executing time on you php server xampp or web server.
