PHP - Edit last row in foreach

I have the following code to create a music playlist based on files in a folder. The issue is that the foreach section will echo the comma of the last row. Here is the code below:

echo '<script type="text/javascript">
                $(document).ready(function(){
                    new jPlayerPlaylist({
                        jPlayer: "#jquery_jplayer_'. $counter .'",
                        cssSelectorAncestor: "#jp_container_'. $counter .'"
                    }, [';

            foreach(glob('files/'. $dir .'/*.mp3') as $file) {
                $filename = $file;
                $parts = Explode('/', $filename);
                $filename = $parts[count($parts) - 1];
                echo '{';
                echo 'title:"'. $filename .'",';
                echo 'mp3:"'.$file.'",';
                echo '},';
            } 
            echo'
                ], {
                    swfPath: "js",
                    supplied: "oga, mp3",
                    wmode: "window"
                    });
                });
            </script>'; 
            $counter ++;
    }

with the line with the comma being line 15 here:

            echo '},';

Does anyone know of a simple solution to this. I've been racking my head trying to find out all day that nothings making sense anymore. CHEERS!

If I understood correctly what you wanna do: Try to make your loop with iterator, then you will be able to check if there is next object to iterate.

Get the files before loop, and the count of it, then check on every iteration

$files = glob('files/'. $dir .'/*.mp3');
$fCnt = count($files);
foreach($files as $i => $file) {
   -- SNIP --
   echo '}' . ($i != $fCnt - 1 ? ',' : '');
}
