How to write a PHP variable in Javascript?

Question

This is my JavaScript function:

    $('.btn-setting').click(function (e) {
    e.preventDefault();
    $('#myModal').modal('show');
});

And this is how I call it in PHP file:

   <div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel"
     aria-hidden="true">

My question is: how to pass a variable in:

   $('#myModal<?php $variable ?>').modal('show');

And call it in a PHP file like this:

<div class="modal fade" id="myModal<?php echo $variable ;>?" tabindex="-1" role="dialog" aria-labelledby="myModalLabel"
     aria-hidden="true">

You need to echo the PHP variables. According to the vampires :) — Jay Blanchard

If you have short tags enabled, you can use <?=$variable;?>. — jtrumbull

In your php file, you need echo variable in your script, like

<script>
$('#myModal<?php echo $variable; ?>').modal('show');
</script>

If you echo in .js file, it doesn't work

Update answer

In html section of php file you need echo variable like below

<div class="modal fade" id="myModal<?=$variable?>" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
