16 | - Create an object:<br>
17 | `$template = new Template();`
18 | - Set template variables, single:<br>
19 | `$template->assign( 'my_var', 'test' );`
20 | - Set template variables, loops:<br>
21 | `$template->assign( 'items', array( array( 'name' => 'First' ), array( 'name' => 'Second' ) ) );`
22 | - Parse template:<br>
23 | `$template->parse( 'tpl.html' );`
