javascripts within php function

can I write javascript code within <script >tag inside php function.

Because when I use html within php function html does not work so I use print or echo function similarly i thought whether I can use java scripts wíthink php function ?.

If yes , how can i do so.pls reply

The thing is that PHP is Server-Side. And JScript is Client-Side. You can use PHP to print javascript code that will then be executed by the browser but you cannot run javascript code within PHP code. It's not how it works.

I mean , can i treat java scripts also like html like you said.

if its like that , i meán like you said then thanks , i will give a try
thanks

I'm sorry, I misunderstood. Yes you can print javascript code like html code. Just be careful with the quotes.
