use unlink() to delete a file.

$filename = "myfile.txt";
unlink($filename); 

but can u please tell me how to include it in that code under every file?

You need to create a delete link for each file, passing in the file to be deleted in the link. The delete link will be similar to the link used for viewing the file. Example delete link could be

                        $deletelink = "<a href=\"delete.php?folder=$view&file=$file\">Delete</a>";

Now in delete.php you'd make sure a) the user owns that file (it should be in their own folder) and b) the file exists. Then you you can pass the file to the unlink function suggested by paddyfields to delete it.

i've done that thanks ,, but is there anyway delete teh file without leaving current page?

You could use AJAX to deal with the request as it allows you to remain on the same page. I'd recommend using jQuery to make the AJAX request too, it makes it a lot more straight forward to code.
