When I visit programming talk I find out a hot topic talking about Levyo Ajax Technology Gallery. Their site is at
http://levyo.com. They build Ajax application on PHP, Mysql. Their gallery runs so fast, especially when I login, register, submit, rate, write comment, upload, process, Tab feature... It's great.
How can they do especially "unlimited tab feature", you can add new category in Admin CP, it generates new Tab automatically? How can we programm an Ajax Application on PHP?
