## Example usage
```php
// Assign the variable on the connection
$db->let('name', [
	"first" => "Tobie",
	"last" => "Morgan Hitchcock",
]);

// Use the variable in a subsequent query
$db->query('CREATE person SET name = $name');

// Use the variable in a subsequent query
$db->query('SELECT * FROM person WHERE name.first = $name.first');
```

You can remove the variable from the connection using the [`unset()` method](/docs/reference/php/v1/methods/unset.md).
