$my = array();
$my['qwe'] = '';
$my['asd'] = '';
$my['zxc'] = '';

$my['']// inside '' will be autosuggest

你也可以使用PHPdoc(CTRL Q)：

/**
 * keys:
 * <pre>
 * some_array   (array)
 * some_bool    (boolean)
 * some_double  (double)
 * some_nice_integer    (integer)
 * </pre>
 * @return array
 */
public function toArray(){
    // return some array
}
