Composer

composer require onebytesolutions/database

Initialization

Simple initialization:

use OneByteSolutions\Database\Database,
    OneByteSolutions\Database\Adapters\PdoAdapter;

// set db config
$db = [
    'host' => 'localhost',
    'user' => 'db-username',
    'pass' => 'db-password',
    'database' => 'database-name'
	// OPTIONAL: ,'port' => 3308 
];

// try to connect to the database
try {
    $database = new Database(new PdoAdapter($db));
    $database->connect();
}catch (\Exception $e){
    echo "Unable to connect: ".$e->getMessage();
}

Insert Query

Simple example

// example of inserting a new user, with transactions
$database->beginTransaction();
try {
    $row = [
        'name' => 'John Doe',
        'email' => 'john.doe@example.org'
    ];
    $id = $database->insertRow("users", $row);
    $database->commit();
    
    echo 'inserted id: '.$id;
} catch(\Exception $e){
    echo 'insert failure';
    $database->rollBack();
}

Insert Batch Query

Simple example

// example of inserting a bunch of rows
$rows = [];
$rows[] = [
        'name' => 'John Doe ',
        'email' => 'john.doe@example.org'
];
$rows[] = [
        'name' => 'Jane Doe ',
        'email' => 'jane.doe@example.org'
];
$rows[] = [
        'name' => 'Sarah Doe ',
        'email' => 'sarah.doe@example.org'
];
$database->insertRowBatch("users", $rows);

Update Query

// example of updating a row
$database->updateRowWhere("user", ["lastLogin" => time()], "id", 1);

Select Query

// example of fetching a query as an array
$sql = "SELECT * FROM users LIMIT 30";
$params = [];
$results = $database->queryToArray($sql, $params);

echo '<pre>'.print_r($results,true).'</pre>';

Delete Query

// example of deleting a row
$database->deleteWhere("users", "id", 1);

Raw Query

// example of running raw sql
$database->run("UPDATE users SET name = :name", ['name' => 'Alex Doe']);
