| ||
$var | mixed | variable to be dumped |
$depth | integer | maximum depth that the dumper should go into the variable. Defaults to 10. |
$highlight | boolean | whether the result should be syntax-highlighted |

public static function dump($var,$depth=10,$highlight=false)
{
echo self::dumpAsString($var,$depth,$highlight);
}
Displays a variable. This method achieves the similar functionality as var_dump and print_r but is more robust when handling complex objects such as Yii controllers.
