一个导出类分享给大家，有更好的也可以讨论

php导出类。支持csv和phpexcel,以前写的

namespace Common\Event;
use Common\Controller\CommonController;
/**

class DataPutEvent extends CommonController{
public function _initialize(){
parent::_initialize();
C('SHOW_PAGE_TRACE',false);
}
/***

function test(){
$head = array('哈哈','呵呵','嘿嘿','嘎嘎','赫赫','嘻嘻',);
$data = array(
'0'=>array(
