PHPexcel导出

标签：限制   cti   sql查询   导出   ati   时间   office   orm   ast   

写过很多次的导出，依旧每次导出的时候都会忘记一些必要参数，趁着有时间记录下

参数设置 $header 列头

　　　　$datas 数据

　　　　$fileName 文件名称

　　　　$sheet sheet名称

　　　　$isDown 文件保存到指定文件还是直接输出

 public  function excelout($header,$datas,$fileName,$sheet,$isDown=false)
    {
        ini_set ("memory_limit","-1"); //内存无限制
        $obj = new PHPExcel();
        $obj->setActiveSheetIndex(0); //激活默认sheet
        $obj->getActiveSheet()->setTitle($sheet); //设置激活sheet的名称
        //头部及列设置 
        $jisuan = 0;
        foreach ($header as $key=>$headerlist ){
            if($key>25){ //当导出列大于25列时处理
                $list[]= chr(65).chr(65+$jisuan);
                $obj->getActiveSheet()->getColumnDimension(chr(65).chr(65+$jisuan))->setWidth(20);
                $obj->getActiveSheet()
                    ->setCellValue($list[$key] . 1, $headerlist);
            }else{
                $list[]=chr(65+$jisuan);
                $obj->getActiveSheet()->getColumnDimension(chr(65+$jisuan))->setWidth(20);
                $obj->getActiveSheet()
                    ->setCellValue($list[$key] . 1, $headerlist);
            }
