What is client side script and server side script?

Answer 1

Try seeing source code of the webpages in your google chrome .

you won't be able to see PHP scripts but html css js are present.

This is because the PHP files of any webpage are processed in the server side and only results are given to your browser.

Where as HTML JS CSS are processed at the client side which is your browser .

So you will have the entire source code of HTML CSs JS but only results of PHP.

Html css js are client side scripts
PHP is server side script.
