README

TBP is a light framework designed to develop small and medium websites. Focused in component oriented

Database interfaces

SQLite

Connector to SQLite3. Works with prepared statements (mandatory). Support for transactions.

Installation

PHP extension ext-sqlite3 required. Check phpinfo(). By default, tbp-web-server Docker image supports SQLite.

Add to your composer.json, at require section:

"ext-sqlite3": "*"

Configuration

Create a config file, like 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=

Implementation

Create a Domain extending AbstractSqliteDomain and pass your config file. Add one method for each needed query.

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));
    }
}

Usage

sample straight-forward code:

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

sample code with transactions:

$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";
}
