Backup MySQL

Ho il codice riportato sotto che effettua un backup di un intero Db e me lo fa scaricare....
Io volevo effettuare una modifica: Invece che farlo scaricare salvarlo nella directory.....
Ho cercato la stringa fwrtite ma nn la ho trovata quindi non so come modificarlo....

Codice PHP:

---

$target="file";
if($target=="file")

header('Content-Type: application/octetstream');
header('Content-Disposition: filename="backup.sql"');
$asfile="download";

Ti basta modificare il valore di $target a "download" e aggiungere:

Codice PHP:

---

if($target == "download")
fwrite(@fopen(time().".sql","w+"),$dump_buffer);


---

dopo:

Codice PHP:

---

echo $dump_buffer;


---

Ciao!

Ho impiegato 30 minuti per capire dove mettere la modifica, e più che dopo direi di metterla al posto di echo $dump_buffer;
serviva anche a me un script così, grazie mille

grazie 1000 !!
CIAO!
