Sqlite

[Werwolfe]

Ragazzi ho fatto uno script per estrarre dai dati da un file sqlite :

<?php

$db=sqlite_open("data2117.sql");

$query=sqlite_unbuffered_query($db,"select * from amministratore");
print($query);
print("

");
foreach($query as $r) {
    print_r($r);
    print("
");
};

sqlite_close($db);

unset($db);

?>

ma mi da questo errore


Fatal error: Call to undefined function sqlite_open() in /home/default/user/htdocs/prova6.php on line 4
