Requirements

• PHP 5.3 or higher is required.
• PHP extension MySQL or SQLite.

Composer installation

1. Get Composer.
2. Require SimplePDO with php composer.phar require dimns/simplepdo or composer require dimns/simplepdo (if the composer is installed globally).
3. Add the following to your application's main PHP file: require 'vendor/autoload.php';.

Usage

// Init class for MySQL (default port 3306)
$db = new DimNS\SimplePDO\MySQL('server', 'dbname', 'username', 'password');
// Or init class for MySQL (override port)
$db = new DimNS\SimplePDO\MySQL('server', 'dbname', 'username', 'password', 3307);
// Or init class for SQLite
$db = new DimNS\SimplePDO\SQLite('/path/to/database/file.sqlite');

// Query without prepared variables
$result = $db->query('SELECT `field1`, `field2` FROM `table`');
echo '<pre>';
print_r($result);
echo '</pre>';

// Query with prepared variables
$result = $db->query('INSERT INTO `table` SET
    `field1` = :field1,
    `field2` = :field2
', [
    'field1' => 'Simple string',
    'field2' => 123,
]);
echo $result;

// Transaction (only for mysql innodb table)
$result = $db->transaction([
    [
        'query' => 'INSERT INTO `table` SET `field1` = :field1, `field2` = :field2, `field3` = :field3',
        'data'  => [
            'field1' => 'val1',
            'field2' => 'val2',
            'field3' => 'val3',
        ],
    ], [
        'query' => 'UPDATE `table` SET `field1` = :field1 WHERE `field2` > :field2',
        'data'  => [
            'field1' => 'val1',
            'field2' => 'val2',
        ],
