sqlite_factory
(PHP 5 < 5.4.0)
sqlite_factory — Opens an SQLite database and returns an SQLiteDatabase object
설명
$filename
[, int $mode = 0666
[, string &$error_message
]] )sqlite_factory() behaves similarly to sqlite_open() in that it opens an SQLite database or attempts to create it if it does not exist. However, a SQLiteDatabase object is returned rather than a resource. Please see the sqlite_open() reference page for further usage and caveats.
