PHP work with JS Jquery
<p>How do i make PHP work with JS?
I mean more like, i want to check if the user is logged in or not, 
and if he is then it will:
$("#message").fadeIn("slow");  ..</p>

<p>How should i do this? 
I have an idea maybe have a file that checks it in php, and then it echo out 1 or 0.</p>

<p>And then a script that checks if its getting 1 then do the message fade in.. But im not as so experienced to script that in JS</p>
