Use php variable in javascript function

[emilia.woo@gmail.com]

Hello guys.
I have a question about js function and php variables.

I want to use php variables in javascript function. For example,


<?php
$ex=(int)$_POST['Example'];
?>

$ex value is 3

There's js function named "practice"
I want to run

<input type="button" onclick="practi ce(3); ">

in this case, 3 is $ex. However, I cannot use like this:

<input type="button" onclick="practi ce( <? $ex ? ); ">

How can I use php variables in javascript function? Thank you.

Yes, that works. You can assign javascript variables with php like that,
just remember that it doesn't work the other way though, you can't assign
php variables with javascript. :)

Re: Use php variable in javascript function

You have to keep in your mind that, in fact, PHP only mission is to 'paint'
the data that travel to the user browser.

Knowin' that, you can 'send' html, javascritp, css... plain text, or what
ever you want. Then the browser will treat is exactly as if it were reading
a normal .html file for example.
