ThinkPHP+PHPExcel[导入][导出]实现方法

以下是我自己的实现方法，可能存在很多不足，欢迎大家提出改进...
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CommonAction.class.php中添加以下两个函数：/**
+----------------------------------------------------------
* Export Excel | 2013.08.23
* Author:HongPing
+----------------------------------------------------------
* @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 $objPHPExcel->setActiveSheetIndex(0)->setCellValue($cellName[$i].'2', $expCellName[$i][1]);
}
// Miscellaneous glyphs, UTF-8
for($i=0;$i for($j=0;$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;
}

}使用方法
导入：function impUser(){
if(isset($_FILES["import"]) && ($_FILES["import"]["error"] == 0)){
$result = $this->importExecl($_FILES["import"]["tmp_name"]);
if($result["error"] == 1){
$execl_data = $result["data"][0]["Content"];
foreach($execl_data as $k=>$v){
..这里写你的业务代码..
}
}
}
}导出：function expUser(){//导出Excel
$xlsName = "User";
$xlsCell = array(
array('id','账号序列'),
array('account','登录账户'),
array('nickname','账户昵称')
);
$xlsModel = M('Post');
$xlsData = $xlsModel->Field('id,account,nickname')->select();
$this->exportExcel($xlsName,$xlsCell,$xlsData);
