Thinkphp中使用PHPExcel 导入导出excel

ThinkPHP版本：3.2.3

PHPExcel版本：1.8

PHPExcel 官方下载地址：https://github.com/PHPOffice/PHPExcel

下载解压后目录结构如下：



1、将目录中的 Classes 文件夹改名为 PHPExcel，

2、改名后的文件夹 复制到 Thinkphp/Library/Vender/ 目录下

完成后目录结构如下：



3、Application/Admin/Common/function.php 内添加导入导出excel的函数，代码如下：

/**

+----------------------------------------------------------
* @param {string} $expTitle     导出后的文件名前缀
* @param {string} $expCellName  标题栏
* @param {array}  $expTableData 内容数组
*/
function export_excel($expTitle,$expCellName,$expTableData){
$xlsTitle = iconv('utf-8', 'gb2312', $expTitle);//文件名称
$fileName = $expTitle.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]]);
}
}

exit;
}

function import_excel($file){
if(!file_exists($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();

}

注意：ob_end_clean();//清除缓存,避免中文乱码， 这一行非常重要 ，要放在所有header（）前面

4、使用：查询mysql数据库并导出excel

后台代码：Application/Admin/Controller/MemberController.Class.php

public function expt(){

$title  = "Member";
$th  = array(
array('id','用户id'),
array('truename','姓名'),
array('phone','手机号')
);
$data  = M('Member')->Field('id,truename,phone')->select();
export_excel($title,$th,$data);
}

4.2、导入excel

public function impt(){
if(isset($_FILES["import"]) && ($_FILES["import"]["error"] == 0)){
$result = import_execl($_FILES["import"]["tmp_name"]);
if($result["error"] == 1){
$execl_data = $result["data"][0]["Content"];
foreach($execl_data as $k=>$v){
#循环写入数据库，或者开启事务..
}
}
}
}

前台代码: Application/Admin/View/Index/member.html

<a href="{:U('Admin/expt')}">导出Excell</a>
<br />
<form action="" name="impt" id="impt" method="post" enctype="multipart/form-data">
<h3>导入Excel：</h3><input  type="file" name="import" />
<input type="submit"  value="导入" onclick="impt();"/>
</form>

<!-- other code -->

<script type="text/javascript">
function impt(){
document.getElementById('impt').action="__APP__/Admin/Member/impt";
document.getElementById('impt').submit();
}
</script>
