PHP request with download and the erase of files

Hi,

I need to save informations in my database about the pictures downloaded with CKFinder (name, size of the image...) and erase all this informations when this picture is delete (with CKFinder too).

Is it posible to integrate a PHP request like

$requete=mysql_db_query($sql,"DELETE FROM table_images ...
AND
$requete=mysql_db_query($sql_sql,"INSERT INTO images ...

Which will be execute when the user download and the erase pictures (or other files...) ?

Thanks for helping me,
Robin
