ThinkPHP 操作Excel进行读写

/ 0评 / 0赞
  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：

$objPHPExcel->getProperties()->setCreator("Maarten Balliauw");
最后修改人
$objPHPExcel->getProperties()->setLastModifiedBy("Maarten Balliauw");

$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.");
关键字
$objPHPExcel->getProperties()->setKeywords("office 2007 openxml php");
种类
$objPHPExcel->getProperties()->setCategory("Test result file");
设置当前的sheet
$objPHPExcel->setActiveSheetIndex(0);
设置sheet的name

$objPHPExcel->getActiveSheet()->protectCells('A3:E13', 'PHPExcel');
设置格式
// Set cell number formats
echo date('H:i:s') . " Set cell number formats\n";

// Set column widths
$objPHPExcel->getActiveSheet()->getColumnDimension('B')->setAutoSize(true);
$objPHPExcel->getActiveSheet()->getColumnDimension('D')->setWidth(12);
设置font
$objPHPExcel->getActiveSheet()->getStyle('B1')->getFont()->setName('Candara');
$objPHPExcel->getActiveSheet()->getStyle('B1')->getFont()->setSize(20);
$objPHPExcel->getActiveSheet()->getStyle('B1')->getFont()->setBold(true);
$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('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()->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);
}
