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

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);
}

/**
* 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:

<!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

<?php
namespace 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:
