Difference between client side and server side.

Server side
Server side script are processed at server after server get request for a PHP document.
After request for an PHP document was sent, server is processing PHP code and it generates HTML code that is sent to a client.
This means that page which client sees doesn’t exist anywhere on the server in such form.

Client side
Main an most used language of client side group is JavaScript.
Code written in Javascript is often included in an basic HTML code and it’s executed at the client explorer.
This kind of code is visible to everybody.

Let me show you examples:

Client side

<script language=”JavaScript”>

var v = new Date()

document.write(v.getHours())

document.write(”:”)

document.write(v.getMinutes())

document.write(”:”)

document.write(v.getSeconds())

</script>

and

Server side

<?

$time= date(”H:i:s”);

echo $time;

<?
