 “require”: {

```

how to use it:
--------------

[](#how-to-use-it)

### database initialization:

[](#database-initialization)

```php5
<?php
require\_once ‘Database.php’;

// pdo
$db = Database::connect(‘pdo’, ‘mysql:dbname=test;host=localhost’, ‘root’, ‘root’);
$db = new Database(‘pdo’, ‘mysql:dbname=test;host=localhost’, ‘root’, ‘root’);

$db = Database::connect(array(‘pdo’, ‘mysql:dbname=test;host=localhost’, ‘root’, ‘root’));
$db = new Database(array(‘pdo’, ‘mysql:dbname=test;host=localhost’, ‘root’, ‘root’));

$link = new PDO;
$db = Database::connect($link);
$db = new Database($link);

// mysql
$db = Database::connect(‘mysql’, ‘localhost’, ‘root’, ‘root’, ‘test’);
$db = new Database(‘mysql’, ‘localhost’, ‘root’, ‘root’, ‘test’);

$db = Database::connect(array(‘mysql’, ‘localhost’, ‘root’, ‘root’, ‘test’));
$db = new Database(array(‘mysql’, ‘localhost’, ‘root’, ‘root’, ‘test’));

$link = mysql\_connect(‘localhost’, ‘root’, ‘root’);
mysql\_select\_db(‘test’, $link);
$db = Database::connect($link);
$db = new Database($link);

// mysqli
$db = Database::connect(‘mysqli’, ‘localhost’, ‘root’, ‘root’, ‘test’);
$db = new Database(‘mysqli’, ‘localhost’, ‘root’, ‘root’, ‘test’);

$db = Database::connect(array(‘mysqli’, ‘localhost’, ‘root’, ‘root’, ‘test’));
$db = new Database(array(‘mysqli’, ‘localhost’, ‘root’, ‘root’, ‘test’));

$link = new mysqli(‘localhost’, ‘root’, ‘root’, ‘test’);
$db = Database::connect($link);
$link = mysqli\_init();
$link→real\_connect(‘localhost’, ‘root’, ‘root’, ‘test’);
$db = Database::connect($link);
$db = new Database($link);

// sqlite
$db = Database::connect(‘sqlite’, ‘test.sqlite’);
$db = new Database(‘sqlite’, ‘test.sqlite’);

$db = Database::connect(array(‘sqlite’, ‘test.sqlite’));
$db = new Database(array(‘sqlite’, ‘test.sqlite’));

$link = new SQLiteDatabase(‘test.sqlite’);
$db = Database::connect($link);
$db = new Database($link);

$link = sqlite\_open(‘test.sqlite’);
$db = Database::connect($link);
$db = new Database($link);

// sqlite3
$db = Database::connect(‘sqlite3’, ‘test.sqlite3’);
$db = new Database(‘sqlite3’, ‘test.sqlite3’);

$db = Database::connect(array(‘sqlite3’, ‘test.sqlite3’));
$db = new Database(array(‘sqlite3’, ‘test.sqlite3’));

$link = new SQLite3(‘test.sqlite3’);
$db = Database::connect($link);
$db = new Database($link);

?>
```

### use the $instance variable

[](#use-the-instance-variable)

```php5
<?php
require\_once ‘Database.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);

return $data; }
?>
```

### demo code:

[](#demo-code)

```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));
?>
```

### database methods:

[](#database-methods)

```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
?>
```

### the class just do the connecting work at initialization. you can exec ‘the initialization sql’ after connect like this, sure, it is lazy-executing just like the connecting.

[](#the-class-just-do-the-connecting-work-at-initialization-you-can-exec-the-initialization-sql-after-connect-like-this-sure-it-is-lazy-executing-just-like-the-connecting)

```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’,
 “SET sql\_mode=’’”
);
// it’s same as above
$db→setConfig(‘initialization’, array(
 ‘SET character\_set\_connection=utf8, character\_set\_results=utf8, character\_set\_client=binary’,
 “SET sql\_mode=’’”
));
?>
```

### use table-prefix

[](#use-table-prefix)

```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);

?>
```
