sqlite_factory
(PHP 5)
sqlite_factory — Opens a SQLite database and returns a SQLiteDatabase object
说明
SQLiteDatabase sqlite_factory
( string $filename
[, int $mode
[, string &$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.
参数
-
filename
-
The filename of the SQLite database.
-
mode
-
The mode of the file. Intended to be used to open the database in
read-only mode. Presently, this parameter is ignored by the sqlite
library. The default value for mode is the octal value
0666 and this is the recommended value.
-
error_message
-
Passed by reference and is set to hold a descriptive error message
explaining why the database could not be opened if there was an error.
返回值
Returns a SQLiteDatabase object on success, NULL on error.
