The only way to do this through HTTP is to create a remote script that
accepts parameters and uses these to select and delete the file. There's
also a HTTP DELETE method, but I have never encountered a server which
supports it.

shortest way :
@unlink($file);

Make sure to check the input first

Apache does, though you need to do a lot of setup to get it to work.
WebDAV is a bit easier to set up, and better supported at the client end.

Do I rite this on my php code as you wrote it?

$nom=$_POST['numero'];
$sql="DELETE FROM canciones WHERE idcancion='$nom';";
mysql_query($sql) or die ("problema con borrado");
$arch=$_POST['ref'];
@unlink($arch);

Is this correct
Thanks I'll download the other option webdav too to see if it works

regards

No, as Arjen already pointed out: check the input. This means you should
check the value of $_POST['ref'], because if you don't the user will be
able to delete any file the webserver has writing rights to.

One way to do it:
check if page is listed in the db
$sql = "SELECT id,page FROM $table WHERE id = '".intval($_POST['id'])."'";

if that query gives one result then execute your code

And I mean execute your code with the results from the query :-) not
from the user input.
