PHPExcel随笔

1.在设置值的时候显示的指定数据类型
$objPHPExcel = new PHPExcel();
$objPHPExcel->setActiveSheetIndex(0);
$objPHPExcel->getActiveSheet()->setTitle('Simple');

$objPHPExcel->getActiveSheet()->setCellValueExplicit('D1',123456789033,PHPExcel_Cell_DataType::TYPE_STRING);

2.在数字字符串前加一个空格使之成为字符串

$objPHPExcel = new PHPExcel();
$objPHPExcel->setActiveSheetIndex(0);
$objPHPExcel->getActiveSheet()->setTitle('Simple');

$objPHPExcel->getActiveSheet()->setCellValue('D1', ' ' . 123456789033);

vendor('PHPExcel.PHPExcel');
$obpe = new \PHPExcel();

//设置当前sheet索引,用于后续的内容操作
//一般用在对个Sheet的时候才需要显示调用
//缺省情况下,PHPExcel会自动创建第一个SHEET被设置SheetIndex=0
//设置SHEET
$obpe->setactivesheetindex();
$obpe->getActiveSheet()->setTitle('电费');

//处理sheet内容
//写入多行数据
foreach($mulit_arr as $k=>$v){
     $k = $k+1;
     /* @func 设置列 */
    $obpe->getactivesheet()->setcellvalue('A'.$k, $v[0]);
    $obpe->getactivesheet()->setcellvalue('B'.$k, $v[1]);
    $obpe->getactivesheet()->setcellvalue('C'.$k, $v[2]);
}


//创建一个新的工作空间(sheet)
$obpe->createSheet();
$obpe->setactivesheetindex(1);

//写入多行数据
foreach($mulit_arr as $k=>$v){
    $k = $k+1;
     /* @func 设置列 */
    $obpe->getactivesheet()->setcellvalue('A'.$k, $v[0]);
    $obpe->getactivesheet()->setcellvalue('B'.$k, $v[1]);
}

//写入类容
    $obwrite = \PHPExcel_IOFactory::createWriter($obpe, 'Excel5'); 

//创建一个新的工作空间(sheet)
    $obpe->createSheet();
    $obpe->setactivesheetindex(1);
    //写入多行数据
    foreach($mulit_arr as $k=>$v){
         $k = $k+1;
          /* @func 设置列 */
         $obpe->getactivesheet()->setcellvalue('A'.$k, $v[0]);
        $obpe->getactivesheet()->setcellvalue('B'.$k, $v[1]);
         $obpe->getactivesheet()->setcellvalue('C'.$k, $v[2]);
    }
                   
    //写入类容
    $obwrite = \PHPExcel_IOFactory::createWriter($obpe, 'Excel5');
    //ob_end_clean();
    //保存文件

    ob_end_clean();//清楚缓存区，解决乱码问题
