Also you can use raw where conditions:
```php
$db->where ("id != companyId");
$results = $db->get("users");
```
Or raw condition with variables:
```php
$db->where("id = ? or id = ?", Array(6,2));
$res = $db->get ("users");
// Gives: SELECT * FROM users WERE id = 2 or id = 2;
```
Optionally you can use method chaining to call where multiple times without referencing your object over an over:
```php
$results = $db
->where('id', 1)
->where('title', 'MyTitle')
->where('login', 'admin')
->get('users');
```

### Helper commands
Reconnect in case mysql connection died
```php
if (!$db->ping())
$db->connect()
```
Obtain an initialized instance of the class from another class
```php
$db = MysqliDb::getInstance();
