javascript files with php code

Hi guys, I'd like to ask for some generic information, if possible.

I usually try to put all my javascript stuff in a single file, and not keep them inside <skript> tags in my views, so it would be a little bit cleaner and tided up. However there might be some cases where I have ti embed some PHP code inside my javascript, for instance:

PHP Code:

<script type="text/javascript">
$(function() {
    $.post('<?php echo base_url($url); ?>', function(data){
        // some code here
    });
});
</script> 


So in this case I'm just leaving these scripts in my views.

I was wondering whether there's a more efficient way to do this, or another better way to organize all javascripts. Would you recommend another way, or in that case, or keep going this way ?
