### Where Method
This method allows you to specify the parameters of the query.
Regular == operator:
```php
$db->where('id', int);
$db->where('title', string);
......@@ -80,6 +81,27 @@ $results = $db->get('tableName');
print_r($results); // contains array of returned rows
```
Custom Operators:
```php
$db->where( 'id', array( '>=' => 50 ) );
$results = $db->get('tableName');
// Gives: SELECT * FROM tableName WHERE id >= ?
```
BETWEEN:
```php
$db->where( 'id', array( 'between' => array(4, 20) ) );
$results = $db->get('tableName');
// Gives: SELECT * FROM tableName WHERE id BETWEEN ? AND ?
```
IN:
``php
$db->where( 'id', array( 'in' => array(1, 5, 27, -1, 'd') ) );
$results = $db->get('tableName');
// Gives: SELECT * FROM tableName WHERE id IN ( ?, ?, ?, ?, ? )
```
Optionally you can use method chaining to call where multiple times without referencing your object over an over:
