PHP Database abstraction layer implementing PDO

Database::initialize();

The ability to fetch data from a database into a nicely formatted associative array is one of the main features of this library.

Fetch all of the rows from a database:

Database::select('Users', '*');

Fetch some rows from a database:

Database::select(
	'Users',
	'*',
	array(
		'limit' => '0,5',
		'orderBy' => 'last_name ASC,first_name ASC' ) );

Getting the number of rows from the previous result

Database::numrows();

Fetch a single row:

Database::select(
	'Users',
	'first_name,last_name,user_email',
	array(
		'where' => array(
			'uid' => 110 ),
		'singleRow' => 'true' ) );

Fetch a single column:

Database::select(
	'Users',
	'user_email',
	array(
		'orderBy' => 'last_name ASC,first_name ASC',
		'fetchStyle' => 'singleColumn' ) );

Fetch a single value:

Database::select(
	'Users',
	'first_name',
	array(
		'where' => array(
			'uid' => 396 ),
		'single' => true ) );

Database::insert(
	'Users',
	array(
		'first_name' => 'Abe',
		'last_name' => 'Lincoln' ) );

Get the last inserted id:

Database::lastInsertId();

Database::update(
	'Users',
	array(
		'uid' => $lastInsertId,
		'first_name' => 'George',
		'last_name' => 'Washington' ),
	array(
		'uid' ) );

Database::delete(
	'Users',
	array(
		'uid' => $lastInsertId ) );

Any SQL statement can be executed. In the following example we will optimize all of the tables in the database.

$tables = Database::listTables();

foreach( $tables as $table )
	Database::sql( "OPTIMIZE TABLE `$table`;" );
