最近在研究php的yii框架,很喜欢,碰到导出excel的问题,研究了一下,就有了下面的方法:

最简单的利用composer安装

composer require "phpoffice/phpexcel": "*"

如果没有安装conposer可以参考下面1.2步

1、引入phpexcel

首先得要下载phpexcel地址:https://github.com/phpoffice/phpexcel/archive/1.8.1.zip

你可以直接在入口文件index.php中引入,也可以在你定义的controller类之前,只要是在你使用之前引入就可以

require dirname(dirname(__file__)).'/excel/phpexcel.php';

或者在phpexcel类里修改相应的namespace也可。

2、按照下面的代码修改phpexcel代码目录里的autoloader.php文件,对比源文件改成:

public static function register() {
  $functions = spl_autoload_functions();
  foreach ( $functions as $function)
    spl_autoload_unregister($function);
    $functions = array_merge(array(array('phpexcel_autoloader','load')),$functions);
  foreach ( $functions as $function)
    $x = spl_autoload_register($function);
    return $x;
}

上面的函数中,注释掉的是原有的代码。

3、下面的代码是输出excel,以及一些常用的属性设置,在controller中:

public function actionexport()
{
    $objectphpexcel = new phpexcel();
    $objectphpexcel->setactivesheetindex(0);
  
    $page_size = 52;
    $model = new newssearch();
    $dataprovider = $model->search();
    $dataprovider->setpagination(false);
    $data = $dataprovider->getdata();
    $count = $dataprovider->gettotalitemcount();
    $page_count = (int)($count/$page_size) +1;
    $current_page = 0;
    $n = 0;
    foreach ( $data as $product )
    {
      if ( $n % $page_size === 0 )
      {
        $current_page = $current_page +1;
  
        //报表头的输出
        $objectphpexcel->getactivesheet()->mergecells('b1:g1');
        $objectphpexcel->getactivesheet()->setcellvalue('b1','产品信息表');
  
        $objectphpexcel->setactivesheetindex(0)->setcellvalue('b2','产品信息表');
        $objectphpexcel->setactivesheetindex(0)->setcellvalue('b2','产品信息表');
        $objectphpexcel->setactivesheetindex(0)->getstyle('b1')->getfont()->setsize(24);
        $objectphpexcel->setactivesheetindex(0)->getstyle('b1')
          ->getalignment()->sethorizontal(phpexcel_style_alignment::horizontal_center);
  
        $objectphpexcel->setactivesheetindex(0)->setcellvalue('b2','日期:'.date("y年m月j日"));
        $objectphpexcel->setactivesheetindex(0)->setcellvalue('g2','第'.$current_page.'/'.$page_count.'页');
        $objectphpexcel->setactivesheetindex(0)->getstyle('g2')
          ->getalignment()->sethorizontal(phpexcel_style_alignment::horizontal_right);
          
        //表格头的输出
        $objectphpexcel->getactivesheet()->getcolumndimension('a')->setwidth(5);
        $objectphpexcel->setactivesheetindex(0)->setcellvalue('b3','编号');
        $objectphpexcel->getactivesheet()->getcolumndimension('b')->setwidth(6.5);
        $objectphpexcel->setactivesheetindex(0)->setcellvalue('c3','名称');
        $objectphpexcel->getactivesheet()->getcolumndimension('c')->setwidth(17);
        $objectphpexcel->setactivesheetindex(0)->setcellvalue('d3','生产厂家');
        $objectphpexcel->getactivesheet()->getcolumndimension('d')->setwidth(22);
        $objectphpexcel->setactivesheetindex(0)->setcellvalue('e3','单位');
        $objectphpexcel->getactivesheet()->getcolumndimension('e')->setwidth(15);
        $objectphpexcel->setactivesheetindex(0)->setcellvalue('f3','单价');
        $objectphpexcel->getactivesheet()->getcolumndimension('f')->setwidth(15);
        $objectphpexcel->setactivesheetindex(0)->setcellvalue('g3','在库数');
        $objectphpexcel->getactivesheet()->getcolumndimension('g')->setwidth(15);
          
        //设置居中
        $objectphpexcel->getactivesheet()->getstyle('b3:g3')
          ->getalignment()->sethorizontal(phpexcel_style_alignment::horizontal_center);
  
        //设置边框
        $objectphpexcel->getactivesheet()->getstyle('b3:g3' )
          ->getborders()->gettop()->setborderstyle(phpexcel_style_border::border_thin);
        $objectphpexcel->getactivesheet()->getstyle('b3:g3' )
          ->getborders()->getleft()->setborderstyle(phpexcel_style_border::border_thin);
        $objectphpexcel->getactivesheet()->getstyle('b3:g3' )
          ->getborders()->getright()->setborderstyle(phpexcel_style_border::border_thin);
        $objectphpexcel->getactivesheet()->getstyle('b3:g3' )
          ->getborders()->getbottom()->setborderstyle(phpexcel_style_border::border_thin);
        $objectphpexcel->getactivesheet()->getstyle('b3:g3' )
          ->getborders()->getvertical()->setborderstyle(phpexcel_style_border::border_thin);
  
        //设置颜色
        $objectphpexcel->getactivesheet()->getstyle('b3:g3')->getfill()
          ->setfilltype(phpexcel_style_fill::fill_solid)->getstartcolor()->setargb('ff66cccc');
          
      }
      //明细的输出
      $objectphpexcel->getactivesheet()->setcellvalue('b'.($n+4) ,$product->id);
      $objectphpexcel->getactivesheet()->setcellvalue('c'.($n+4) ,$product->product_name);
      $objectphpexcel->getactivesheet()->setcellvalue('d'.($n+4) ,$product->product_agent->name);
      $objectphpexcel->getactivesheet()->setcellvalue('e'.($n+4) ,$product->unit);
      $objectphpexcel->getactivesheet()->setcellvalue('f'.($n+4) ,$product->unit_price);
      $objectphpexcel->getactivesheet()->setcellvalue('g'.($n+4) ,$product->library_count);
      //设置边框
      $currentrownum = $n+4;
      $objectphpexcel->getactivesheet()->getstyle('b'.($n+4).':g'.$currentrownum )
          ->getborders()->gettop()->setborderstyle(phpexcel_style_border::border_thin);
      $objectphpexcel->getactivesheet()->getstyle('b'.($n+4).':g'.$currentrownum )
          ->getborders()->getleft()->setborderstyle(phpexcel_style_border::border_thin);
      $objectphpexcel->getactivesheet()->getstyle('b'.($n+4).':g'.$currentrownum )
          ->getborders()->getright()->setborderstyle(phpexcel_style_border::border_thin);
      $objectphpexcel->getactivesheet()->getstyle('b'.($n+4).':g'.$currentrownum )
          ->getborders()->getbottom()->setborderstyle(phpexcel_style_border::border_thin);
      $objectphpexcel->getactivesheet()->getstyle('b'.($n+4).':g'.$currentrownum )
          ->getborders()->getvertical()->setborderstyle(phpexcel_style_border::border_thin);
      $n = $n +1;  
    }
  
    //设置分页显示
    //$objectphpexcel->getactivesheet()->setbreak( 'i55' , phpexcel_worksheet::break_row );
    //$objectphpexcel->getactivesheet()->setbreak( 'i10' , phpexcel_worksheet::break_column );
    $objectphpexcel->getactivesheet()->getpagesetup()->sethorizontalcentered(true);
    $objectphpexcel->getactivesheet()->getpagesetup()->setverticalcentered(false);
  
  
    ob_end_clean();
    ob_start();
  
    header('content-type : application/vnd.ms-excel');
    header('content-disposition:attachment;filename="'.'产品信息表-'.date("y年m月j日").'.xls"');
    $objwriter= phpexcel_iofactory::createwriter($objectphpexcel,'excel5');
    $objwriter->save('php://output');

代码执行后,会直接生成excel,并提示下载或打开。
