ThinkPHP 操作Excel进行读写

/ 0评 / 0
  1. 下载PHPExcel:到官网下载或者链接: https://pan.baidu.com/s/1i4HKWj7 密码: 7wr4
  2. 解压文件夹至ThinkPHP\Library\Org\Util目录下。
  3. 然后就可以进行读写操作了。
  4. 读取Excel:

    
    public function impExcel(){
    //echo $_FILES['file']['name'];
    if (!empty($_FILES)) {
    header("Content-Type:text/html;charset=utf-8");
    $upload = new \Think\Upload();// 实例化上传类
    $upload->maxSize   =     3145728 ;// 设置附件上传大小
    $upload->exts      =     array('xls', 'xlsx');// 设置附件上传类
    $upload->rootPath  ='./';
    $upload->savePath  =      './Public/upload/'; // 设置附件上传目录
    // 上传文件
    $info   =   $upload->uploadOne($_FILES['file']);
    $filename = $info['savepath'].$info['savename'];
    $exts = $info['ext'];
    //print_r($info);exit;
    if(!$info) {// 上传错误提示错误信息
    $rets['info'] = $upload->getError();
    $rets['status'] = 1;
    $this->ajaxReturn($rets, 'json');
    }else {
    import("Org.Util.PHPExcel");
    //创建PHPExcel对象,注意,不能少了\
    $PHPExcel=new \PHPExcel();
    //如果excel文件后缀名为.xls,导入这个类
    if($exts == 'xls'){
    import("Org.Util.PHPExcel.Reader.Excel5");
    $PHPReader=new \PHPExcel_Reader_Excel5();
    }else if($exts == 'xlsx'){
    import("Org.Util.PHPExcel.Reader.Excel2007");
    $PHPReader=new \PHPExcel_Reader_Excel2007();
    }
    //载入文件
    $PHPExcel=$PHPReader->load($filename);
    //获取表中的第一个工作表,如果要获取第二个,把0改为1,依次类推
    $currentSheet=$PHPExcel->getSheet(0);
    //获取总列数
    $allColumn=$currentSheet->getHighestColumn();
    //获取总行数
    $allRow=$currentSheet->getHighestRow();
    //循环获取表中的数据,$currentRow表示当前行,从哪行开始读取数据,索引值从0开始
    $col = array();
    $data = array();
    for($currentRow=1;$currentRow<=$allRow;$currentRow++){
    //从哪列开始,A表示第一列
    $i = 0;$row = array();
    for($currentColumn='A';$currentColumn<=$allColumn;$currentColumn++){ 
    //数据坐标 
    $address=$currentColumn.$currentRow; 
    //读取到的数据,保存到数组$arr中 
    $cell =$currentSheet->getCell($address)->getValue();
    //$cell = $data[$currentRow][$currentColumn];
    if($cell instanceof PHPExcel_RichText){
    $cell  = $cell->__toString();
    }
    /* 列标题 */
    if($currentRow==1){
    $col[$i++] = str_replace('_text','',$cell._text);
    }else{
    $row[$col[$i++]] = str_replace('_text','',$cell._text);
    }
    }
    
    $data[] = $row;
    
    }
    dump($data);
    unlink($filename);
    rmdir('./Public/upload/'.date("Y-m-d"));//上传后删除
    }
    } else {
    echo "上传文件错误!";
    }
    }
    
  5. 写入Excel:
    
    import("Org.Util.PHPExcel");
    //创建PHPExcel对象,注意,不能少了\
    $PHPExcel=new \PHPExcel();
    $objWriter = new \PHPExcel_Writer_Excel5($PHPExcel);
    //接下来就是写数据到表格里面去
    $list =你从数据库查出来的的数据
     foreach ($list as $key => $value) {
                      $i=$key+1;//表格是从1开始的
                      $objPHPExcel->getActiveSheet()->setCellValue('A'.$i,  $value['name']);//这里是设置A1单元格的内容
                      $objPHPExcel->getActiveSheet()->setCellValue('B'.$i,  $value['id']);////这里是设置B1单元格的内容
                      //以此类推,可以设置C D E F G看你需要了。
                      
    }
    //接下来当然是下载这个表格了,在浏览器输出就好了
              header("Pragma: public");
              header("Expires: 0");
              header("Cache-Control:must-revalidate, post-check=0, pre-check=0");
              header("Content-Type:application/force-download");
              header("Content-Type:application/vnd.ms-execl");
              header("Content-Type:application/octet-stream");
              header("Content-Type:application/download");;
              header('Content-Disposition:attachment;filename=文件名称.xls');
              header("Content-Transfer-Encoding:binary");
              $objWriter->save('文件名称.xls');
              $objWriter->save('php://output');
    到这里你就已经完成了。如果有哪里不懂可以留言
                
     上面只是完成了流程而已。但是不可能这样简单而已。我们可以设置很多东西。看自己需要来设置了。
    
     
    
    设置excel的属性:
    创建人
    $objPHPExcel->getProperties()->setCreator("Maarten Balliauw");
    最后修改人
    $objPHPExcel->getProperties()->setLastModifiedBy("Maarten Balliauw");
    标题
    $objPHPExcel->getProperties()->setTitle("Office 2007 XLSX Test Document");
    题目
    $objPHPExcel->getProperties()->setSubject("Office 2007 XLSX Test Document");
    描述
    $objPHPExcel->getProperties()->setDescription("Test document for Office 2007 XLSX, generated using PHP classes.");

    保护cell
    $objPHPExcel->getActiveSheet()->getProtection()->setSheet(true); // Needs to be set to true in order to enable any worksheet protection!
    $objPHPExcel->getActiveSheet()->protectCells('A3:E13', 'PHPExcel');
    设置格式
    // Set cell number formats
    echo date('H:i:s') . " Set cell number formats\n";
    $objPHPExcel->getActiveSheet()->getStyle('E4')->getNumberFormat()->setFormatCode(PHPExcel_Style_NumberFormat::FORMAT_CURRENCY_EUR_SIMPLE);
    $objPHPExcel->getActiveSheet()->duplicateStyle( $objPHPExcel->getActiveSheet()->getStyle('E4'), 'E5:E13' );

    $objPHPExcel->getActiveSheet()->getStyle('B1')->getFont()->setUnderline(PHPExcel_Style_Font::UNDERLINE_SINGLE);
    $objPHPExcel->getActiveSheet()->getStyle('B1')->getFont()->getColor()->setARGB(PHPExcel_Style_Color::COLOR_WHITE);
    $objPHPExcel->getActiveSheet()->getStyle('E1')->getFont()->getColor()->setARGB(PHPExcel_Style_Color::COLOR_WHITE);
    $objPHPExcel->getActiveSheet()->getStyle('D13')->getFont()->setBold(true);
    $objPHPExcel->getActiveSheet()->getStyle('E13')->getFont()->setBold(true);
    设置align
    $objPHPExcel->getActiveSheet()->getStyle('D11')->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_RIGHT);
    $objPHPExcel->getActiveSheet()->getStyle('D12')->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_RIGHT);
    $objPHPExcel->getActiveSheet()->getStyle('D13')->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_RIGHT);
    $objPHPExcel->getActiveSheet()->getStyle('A18')->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_JUSTIFY);
    //垂直居中
    $objPHPExcel->getActiveSheet()->getStyle('A18')->getAlignment()->setVertical(PHPExcel_Style_Alignment::VERTICAL_CENTER);
    设置column的border
    $objPHPExcel->getActiveSheet()->getStyle('A4')->getBorders()->getTop()->setBorderStyle(PHPExcel_Style_Border::BORDER_THIN);
    $objPHPExcel->getActiveSheet()->getStyle('B4')->getBorders()->getTop()->setBorderStyle(PHPExcel_Style_Border::BORDER_THIN);
    $objPHPExcel->getActiveSheet()->getStyle('C4')->getBorders()->getTop()->setBorderStyle(PHPExcel_Style_Border::BORDER_THIN);
    $objPHPExcel->getActiveSheet()->getStyle('D4')->getBorders()->getTop()->setBorderStyle(PHPExcel_Style_Border::BORDER_THIN);
    $objPHPExcel->getActiveSheet()->getStyle('E4')->getBorders()->getTop()->setBorderStyle(PHPExcel_Style_Border::BORDER_THIN);
    设置border的color
    $objPHPExcel->getActiveSheet()->getStyle('D13')->getBorders()->getLeft()->getColor()->setARGB('FF993300');
    $objPHPExcel->getActiveSheet()->getStyle('D13')->getBorders()->getTop()->getColor()->setARGB('FF993300');
    $objPHPExcel->getActiveSheet()->getStyle('D13')->getBorders()->getBottom()->getColor()->setARGB('FF993300');
    $objPHPExcel->getActiveSheet()->getStyle('E13')->getBorders()->getTop()->getColor()->setARGB('FF993300');
    $objPHPExcel->getActiveSheet()->getStyle('E13')->getBorders()->getBottom()->getColor()->setARGB('FF993300');
    $objPHPExcel->getActiveSheet()->getStyle('E13')->getBorders()->getRight()->getColor()->setARGB('FF993300');
    设置填充颜色
    $objPHPExcel->getActiveSheet()->getStyle('A1')->getFill()->setFillType(PHPExcel_Style_Fill::FILL_SOLID);
    $objPHPExcel->getActiveSheet()->getStyle('A1')->getFill()->getStartColor()->setARGB('FF808080');
    $objPHPExcel->getActiveSheet()->getStyle('B1')->getFill()->setFillType(PHPExcel_Style_Fill::FILL_SOLID);
    $objPHPExcel->getActiveSheet()->getStyle('B1')->getFill()->getStartColor()->setARGB('FF808080');
    加图片
    $objDrawing = new PHPExcel_Worksheet_Drawing();
    $objDrawing->setName('Logo');
    $objDrawing->setDescription('Logo');
    $objDrawing->setPath('./images/officelogo.jpg');
    $objDrawing->setHeight(36);
    $objDrawing->setWorksheet($objPHPExcel->getActiveSheet());
    $objDrawing = new PHPExcel_Worksheet_Drawing();
    $objDrawing->setName('Paid');
    $objDrawing->setDescription('Paid');
    $objDrawing->setPath('./images/paid.png');
    $objDrawing->setCoordinates('B15');
    $objDrawing->setOffsetX(110);
    $objDrawing->setRotation(25);
    $objDrawing->getShadow()->setVisible(true);
    $objDrawing->getShadow()->setDirection(45);
    $objDrawing->setWorksheet($objPHPExcel->getActiveSheet());
    //处理中文输出问题
    需要将字符串转化为UTF-8编码,才能正常输出,否则中文字符将输出为空白,如下处理:
     $str  = iconv('gb2312', 'utf-8', $str);
    或者你可以写一个函数专门处理中文字符串:
    function convertUTF8($str)
    {
       if(empty($str)) return '';
       return  iconv('gb2312', 'utf-8', $str);
    }
