ThinkPHP3.2+PHPExcel1.8版类库 实现导入导出excel表

实现步骤：

一：去官网http://phpexcel.codeplex.com/下载最新PHPExcel放到Vendor下，注意位置：ThinkPHP\Extend\Vendor\PHPExcel\PHPExcel.php

(如果下载困难,可以使用1.8版,本来是免积分的,但是下载多了被强行加了2个积分,链接附上:http://download.csdn.net/download/h330531987/9831432)

二：在Controller.class.php中添加以下两个方法：

/**     +----------------------------------------------------------     * @param $expTitle     string File name     +----------------------------------------------------------     * @param $expCellName  array  Column name     +----------------------------------------------------------     * @param $expTableData array  Table data     +----------------------------------------------------------     */    public function exportExcel($expTitle,$expCellName,$expTableData){        $xlsTitle = iconv('utf-8', 'gb2312', $expTitle);//文件名称        $fileName = $_SESSION['loginAccount'].date('_YmdHis');//or $xlsTitle 文件名称可根据自己情况设定        $cellNum = count($expCellName);        $dataNum = count($expTableData);        vendor("PHPExcel.PHPExcel");        $objPHPExcel = new \PHPExcel();        $cellName = array('A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P','Q','R','S','T','U','V','W','X','Y','Z','AA','AB','AC','AD','AE','AF','AG','AH','AI','AJ','AK','AL','AM','AN','AO','AP','AQ','AR','AS','AT','AU','AV','AW','AX','AY','AZ');                $objPHPExcel->getActiveSheet(0)->mergeCells('A1:'.$cellName[$cellNum-1].'1');//合并单元格        $objPHPExcel->setActiveSheetIndex(0)->setCellValue('A1', $expTitle.'  Export time:'.date('Y-m-d H:i:s'));          for($i=0;$i<$cellNum;$i++){            $objPHPExcel->setActiveSheetIndex(0)->setCellValue($cellName[$i].'2', $expCellName[$i][1]);         }           // Miscellaneous glyphs, UTF-8           for($i=0;$i<$dataNum;$i++){          for($j=0;$j<$cellNum;$j++){            $objPHPExcel->getActiveSheet(0)->setCellValue($cellName[$j].($i+3), $expTableData[$i][$expCellName[$j][0]]);          }                     }                  header('pragma:public');        header('Content-type:application/vnd.ms-excel;charset=utf-8;name="'.$xlsTitle.'.xls"');        header("Content-Disposition:attachment;filename=$fileName.xls");//attachment新窗口打印inline本窗口打印        $objWriter = \PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5');          $objWriter->save('php://output');         exit;       }         /**     +----------------------------------------------------------     * @param  $file   upload file $_FILES     +----------------------------------------------------------     * @return array   array("error","message")     +----------------------------------------------------------          */       public function importExecl($file){         if(!file_exists($file)){             return array("error"=>0,'message'=>'file not found!');        }         Vendor("PHPExcel.PHPExcel.IOFactory");         $objReader = \PHPExcel_IOFactory::createReader('Excel5');         try{            $PHPReader = $objReader->load($file);        }catch(Exception $e){}        if(!isset($PHPReader)) return array("error"=>0,'message'=>'read error!');        $allWorksheets = $PHPReader->getAllSheets();        $i = 0;        foreach($allWorksheets as $objWorksheet){            $sheetname=$objWorksheet->getTitle();            $allRow = $objWorksheet->getHighestRow();//how many rows            $highestColumn = $objWorksheet->getHighestColumn();//how many columns            $allColumn = \PHPExcel_Cell::columnIndexFromString($highestColumn);            $array[$i]["Title"] = $sheetname;             $array[$i]["Cols"] = $allColumn;             $array[$i]["Rows"] = $allRow;             $arr = array();            $isMergeCell = array();            foreach ($objWorksheet->getMergeCells() as $cells) {//merge cells                foreach (\PHPExcel_Cell::extractAllCellReferencesInRange($cells) as $cellReference) {                    $isMergeCell[$cellReference] = true;                }            }            for($currentRow = 1 ;$currentRow<=$allRow;$currentRow++){                 $row = array();                 for($currentColumn=0;$currentColumn<$allColumn;$currentColumn++){;                                    $cell =$objWorksheet->getCellByColumnAndRow($currentColumn, $currentRow);                    $afCol = \PHPExcel_Cell::stringFromColumnIndex($currentColumn+1);                    $bfCol = \PHPExcel_Cell::stringFromColumnIndex($currentColumn-1);                    $col = \PHPExcel_Cell::stringFromColumnIndex($currentColumn);                    $address = $col.$currentRow;                    $value = $objWorksheet->getCell($address)->getValue();                    if(substr($value,0,1)=='='){                        return array("error"=>0,'message'=>'can not use the formula!');                        exit;                    }                    if($cell->getDataType()==\PHPExcel_Cell_DataType::TYPE_NUMERIC){                        // $cellstyleformat=$cell->getParent()->getStyle( $cell->getCoordinate() )->getNumberFormat();                        // $formatcode=$cellstyleformat->getFormatCode();                        if (preg_match('/^([$[A-Z]*-[0-9A-F]*])*[hmsdy]/i', $formatcode)) {                            $value=gmdate("Y-m-d", \PHPExcel_Shared_Date::ExcelToPHP($value));                        }else{                            $value=\PHPExcel_Style_NumberFormat::toFormattedString($value,$formatcode);                        }                                    }                    if($isMergeCell[$col.$currentRow]&&$isMergeCell[$afCol.$currentRow]&&!empty($value)){                        $temp = $value;                    }elseif($isMergeCell[$col.$currentRow]&&$isMergeCell[$col.($currentRow-1)]&&empty($value)){                        $value=$arr[$currentRow-1][$currentColumn];                    }elseif($isMergeCell[$col.$currentRow]&&$isMergeCell[$bfCol.$currentRow]&&empty($value)){                        $value=$temp;                    }                    $row[$currentColumn] = $value;                 }                 $arr[$currentRow] = $row;             }             $array[$i]["Content"] = $arr;             $i++;        }         // spl_autoload_register('Think');//must, resolve ThinkPHP and PHPExcel conflicts        unset($objWorksheet);         unset($PHPReader);         unset($PHPExcel);         unlink($file);         return array("error"=>1,"data"=>$array);     }

注意:两个方法应该放在析构方法之前,否则无效(迷...)

/**     * 析构方法     * @access public     */    public function __destruct() {        // 执行后续操作        Hook::listen('action_end');    }

应用实例:

1.文件目录:

2.提交界面:

<!DOCTYPE html><html><head><title>excel</title> </head><body><form method="post" action="{:U('impUser')}" enctype="multipart/form-data">      <h3>导入Excel表：</h3>

<input  type="file" name="import" />        <input type="submit"  value="导入" /></form></body></html>

3.导入导出操作

<?phpnamespace Home\Controller;use Think\Controller;class ExcelController extends Controller{    public function indexAction()    {    $this->display();    }    //导入    public function impUserAction(){     if(isset($_FILES["import"]) && ($_FILES["import"]["error"] == 0)){        $result = $this->importExecl($_FILES["import"]["tmp_name"]);              // echo "<pre>";var_dump($result);die;        if($result["error"] == 1){                    $execl_data = $result["data"][0]["Content"];                  foreach($execl_data as $k=>$v){                    //数据处理                      echo "<hr>";                      dump($v);                  }         }      }}//导出public function expUserAction(){//导出Excel        $xlsName  = "User";        $xlsCell  = array(            array('category_id','序列'),            array('title','标题'),            array('sort_number','权重')        );        $xlsModel = M('category');//数据库查询,具体查询表名和字段根据实际改变        $xlsData  = $xlsModel->Field('category_id,title,sort_number')->select();          // var_dump($xlsData);          // die;        $this->exportExcel($xlsName,$xlsCell,$xlsData);    }

效果:
