# 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.

## 范例

例子 1. sqlite_factory() example

`<?php $dbhandle = sqlite_factory('sqlitedb'); $dbhandle->query('SELECT user_id, username FROM users'); /* functionally equivalent to: */ $dbhandle = new SQLiteDatabase('sqlitedb'); $dbhandle->query('SELECT user_id, username FROM users'); ?>`
