Hi , I'm a web developer from Argentina, I have 5+ years experience on web development. The technologies I use are the followings:
PHP, JSP, HTML, CSS, JS, Jquery, Mootools, YUI Library, Bootstraps, Ajax, Rest, Google Analytics, Yii, mySQL, SPRING MVC, Photoshop, SVN and others.
In my opinion make the website based on PHP will be cheaper (hosting are free for PHP), Yii give us a lot of tools and components already proof.
Regards.
Gabriel
