I am currently investigating what would be the most suitable language to use in order to get a dynamic site such as facebook for e.g. I will start shortly the development phase of my site and I want it to be very interactive with many small functionalities such as videos, drag and drop, tags, comments, publishing of photos by the enduser, online payments, etc.
On many forums I saw that JC and PHP were both complementary and that Ajax was a good way to promote interactivity between users.
I would like to use the hotest and most advanced language in order to get that very interactive website. Anyone could help? Thanks

Using Ajax is a great way to make your site dynamic with the client not having to constantly reload there browser.

Hi, thanks for your reply. Does Ajax involves lots of time for development? is Ajax the best and latest technology to create interactivity with your clients? Do you have some sites examples that you can share with me that were created in ajax? thanks
