Question

I’m trying to delete files (picture files) in a folder only if they’re not present in a specific database table.

Just like a check of filenames and if they’re present in the table it’s ok but if not delete them.

Any ideas how to do that?

Answer 1

Just select all pictures that shouldn’t be deleted from database and go through all files.

$result = mysql_query("SELECT filename FROM no_delete");
while($row = mysql_fetch_assoc($result)) {
   $do_not_delete[] = $row['filename'];
}

foreach(glob("*") as $filename) {
    if (!in_array($filename, $do_not_delete)) {
        //delete them
    }
}
