http://qpost.com/q/differences differences between javascript and PHP en-us javascript is a client side language, it allows you to perform operation on data on the page for user interaction and everything happens on the users internet browser. However php is a server side language and the user never sees it. It basically gets executed on the server and returns meaningful html constructed pages by going through the logic og the website functionality. So, in order to refresh data on a webpage you would send a request to eh server and php gets executed on theserver and responds with data (html). When you use javascript things are not sent to the server because it opnoly allows you to manipulate any data that is already present, so for example hiding some of the data making sliding windows effects int he page such as navigation slides etc. harvinder Fri, 01 Aug 2008 15:24:49 +0000 http://qpost.com/q/permalink/77 77
