TBP

TBP adalah kerangka kerja ringan yang dirancang untuk mengembangkan situs web kecil dan menengah. Fokus dalam berorientasi komponen

Antarmuka basis data

Sqlite

Konektor ke SQLite3. Bekerja dengan pernyataan yang disiapkan (wajib). Dukungan untuk transaksi.

Instalasi

PHP Extension ext-sqlite3 diperlukan. Periksa phpinfo() . Secara default, gambar Docker tbp-web-server mendukung SQLite.

Tambahkan ke composer.json Anda, di bagian require :

 "ext-sqlite3": "*"

Konfigurasi

Buat file konfigurasi, seperti config/my-sqlite.config

 # TBP/SQLite config file.
# ALL PARAMETERS ARE OPTIONAL!

# Database file name (if not defined, will use 'default.db')
filename=resources/test.db

# Access type
# readOnly=yes

# Encryption key (if not defined, no encryption used)
# encryptionKey=

Pelaksanaan

Buat domain memperluas AbstractSqliteDomain dan lewati file konfigurasi Anda. Tambahkan satu metode untuk setiap kueri yang diperlukan.

 class MyDomain extends AbstractSqliteDomain
{
    public function __construct ()
    {
        $ configReader = new Config ( __CONFIG_PATH__ );            // <-- get a config reader, passing your config folder
        $ config = $ configReader -> getConfig ( ' my-sqlite ' );        // <-- read your configuration, passing your config base name
        $ config -> filename =                                     // <-- convert your relative path into absolute path
            __BASE_PATH__ .
            DIRECTORY_SEPARATOR .
            $ config -> filename ;
        parent :: __construct ( $ config );
        $ this -> open ();                                          // <-- open a db connection and let's rock!
    }

    public function addRegister ( $ a , $ b )
    {
        $ sql = " INSERT INTO `MyTableWithAutoInc` (`a`, `b`) VALUES (?, ?) " ;
        $ params = array ( $ a , $ b );
        return self :: insertWithAutoincrement ( $ this -> connection -> command ( $ sql , $ params ));
    }

    public function addAnotherRegister ( $ a , $ b )
    {
        $ sql = " INSERT INTO `MyOtherTable` (`a`, `b`) VALUES (?, ?) " ;
        $ params = array ( $ a , $ b );
        return $ this -> connection -> command ( $ sql , $ params );
    }

    public function getRegisters ( $ b )
    {
        $ sql = " SELECT * FROM `MyTableWithAutoInc` WHERE `b` <= ? " ;
        $ params = array ( $ b );
        return self :: getAll ( $ this -> connection -> select ( $ sql , $ params ));
    }

    public function getRegisterById ( $ id )
    {
        $ sql = " SELECT * FROM `MyTableWithAutoInc` WHERE `MyId` = ? " ;
        $ params = array ( $ id );
        return self :: getSingle ( $ this -> connection -> select ( $ sql , $ params ));
    }
}

Penggunaan

Contoh kode lurus-maju:

 $ domain = new MyDomain ();
$ results = $ domain -> getRegisters ( 9391 ); // get an array

Kode sampel dengan transaksi:

 $ domain = new MyDomain ();
try {
    $ domain -> begin ();
    
    $ lastId = $ domain -> addRegister ( 1 , 2 );
    echo " first query: last inserted id: $ lastId n" ;
    
    $ lastId = $ domain -> addRegister ( 3 , 4 );
    echo " second query: last inserted id: $ lastId n" ;
    
    $ domain -> commit ();
} catch ( Exception $ e ) {
    $ domain -> rollback ();
    echo " ERROR: " . $ e -> getMessage () . "n" ;
}
