PHP file_get_contents使用变量

Question

I am trying to send the contents of javascript file using file_get_contents. The problem i'm having is the javascript contains some PHP variables:

<script>
jQuery('document').ready(function($){
    $('a.ajax_link').click(function(){
        $.ajax({
            type: 'DELETE',
            url: '/groups/$org_ID/leave/$member_ID',

            success: function(data){
                var data = $('<div>').html(data);
                var msg1 = data.find('#msg1');

                $('#data_box1').html(msg1).hide().fadeIn(500).delay(2000).fadeOut(500);
                setTimeout('window.location.href =\"/groups/\"',3000);
            }
        });

    });
});
</script>

Specifically, the url: line. That just stays as plain text and so my script fails. I now understand this is the behavior of file_get_contents but how can I go about doing this?

thanks!

Use output buffering and require:

$org_ID = 5;
$member_ID = 10;
ob_start();
require '/path/to/javascript_file.php';
$js_code = ob_get_clean();

Inside javascript file you'll have to use php tags:

url: '<?php echo "/groups/$org_ID/leave/$member_ID"; ?>'
