the database abstraction supports mysql mysqli PDO SQLiteDatabase AND SQLite3 now, and will support more in future…
for more infomations plz hit here

```php5
<?php

// set the Database::$instance
Database::$instance = Database::connect(‘mysql’, ‘localhost’, ‘root’, ‘root’, ‘test’);

//in some function, u can use them like this:

print_r(test());

function test() {
$sql = “SELECT * FROM test WHERE id = ?”;
$data = Database::$instance→getRow($sql, 1);

}
?>
```

```php5
<?php
// origin sql
$sql = “SELECT * FROM test_table WHERE id = ‘$id’ AND name = ‘$name’”;
$result = $db→getAll($sql);

// if there are variables in sql, you can do it like this, and don’t need to process the variables. : )
$sql = “SELECT * FROM test_table WHERE id = ? AND name = ?”;
$result = $db→getAll($sql, $id, $name);

// you can allso use:
$sql = “SELECT * FROM test_table WHERE id = ? AND name = ?”;
$result = $db→getAll($sql, array($id, $name));

// it allso support:
$sql = “SELECT * FROM test_table WHERE id = :id AND name = :name”;
$result = $db→getAll($sql, array(‘name’=>$name, ‘id’=>$id));
?>
```

```php5
<?php
public function getRow();
// get a row result
public function getCol();
// get a col result
public function getOne();
// get a column value
public function getAll();
// get all results
public function exec();
// execute a sql
public function lastInsertId();
// get the id of the last inserted row or sequence value
public function getDriver();
// get the origin link or object of the database driver
public function query();
// execute a sql and returns a statement object
public function fetch($query);
// fetch a result whith the statement object from query
?>
```

```php5
<?php
//mysql
$db = Database::connect(‘mysql’, ‘localhost’, ‘root’, ‘root’, ‘test’);
$db→initialization = array(
‘SET character_set_connection=utf8, character_set_results=utf8, character_set_client=binary’,

```php5
<?php
//mysql
$db = Database::connect(‘mysql’, ‘localhost’, ‘root’, ‘root’, ‘test’);

$db→setConfig(‘tablePreFix’, ‘db_’);
// or set multi table-prefix
$db→setConfig(‘tablePreFix’, array(
‘db1_’=>array(‘table1’, ‘table2’),
‘db2_’=> ‘*’ // means the other tables use ‘db2_’ prefix
));

// and u can get the table name by getTable function

$table_name = $db→getTable(‘table1’); // db1_table1

// and the sql will be auto replaced the table name with ‘tablePreFix’ by dafault if you use ‘{{tablename}}’ in sql

$sql = “SELECT * FROM {{table1}}”;
// SELECT * FROM db1_table1
$result = $db→getAll($sql);

// and you can disable the auto-replace by using:

$db→setConfig(‘replaceTableName’, false);
