excel导入导出

这里实现的PHP导入导出excel功能用到的是开源PHPExcel，执行下面的操作之前请先下载该类库文件，官方网站：http://www.codeplex.com/PHPExcel，官网案例代码很多，导出pdf什么的都有，这里主要介绍PHP导入导出excel的功能，导出excel文件是office2007格式，同时兼容2003。php导入excel导入的excel文件的数据格式，截图如下：下面是将该excel文件的数据导入到数据库的具体代码： 代码如下:<?phprequire_once 'Classes/PHPExcel.php';require_once'Classes/PHPExcel/IOFactory.php';require_once'Classes/PHPExcel/Reader/Excel5.php';$objReader=PHPExcel_IOFactory::createReader('Excel5');//use excel2007 for2007 format$objPHPExcel=$objReader->load($file_url);//$file_url即Excel文件的路径$sheet=$objPHPExcel->getSheet(0);//获取第一个工作表$highestRow=$sheet->getHighestRow();//取得总行数$highestColumn=$sheet->getHighestColumn(); //取得总列数//循环读取excel文件,读取一条,插入一条for($j=2;$j<=$highestRow;$j++){//从第一行开始读取数据 $str=''; for($k='A';$k<=$highestColumn;$k++){            //从A列读取数据 //这种方法简单，但有不妥，以'\\'合并为数组，再分割\\为字段值插入到数据库,实测在excel中，如果某单元格的值包含了\\导入的数据会为空          $str.=$objPHPExcel->getActiveSheet()->getCell("$k$j")->getValue().'\\';//读取单元格 } //explode:函数把字符串分割为数组。 $strs=explode("\\",$str); $sql="INSERT INTO `".TB_PREFIX."business`(`username`,`password`,`company`,`prov`,`address`,`btime`,`phone`,`email`,`name`) VALUES ( '{$strs[0]}', '{$strs[1]}', '{$strs[2]}', '{$strs[3]}', '{$strs[4]}', '{$strs[5]}', '{$strs[6]}', '{$strs[7]}', '{$strs[8]}')"; $db->query($sql);//这里执行的是插入数据库操作}unlink($file_url); //删除excel文件?>php导出excel下面直接放出本人总结的使用PHP导出Excel的部分调用代码。复制代码 代码如下:<?phperror_reporting(E_ALL);date_default_timezone_set('Asia/Shanghai');require_once'./Classes/PHPExcel.php';$data=array( 0=>array(  'id'=>1001,  'username'=>'张飞',  'password'=>'123456',  'address'=>'三国时高老庄250巷101室' ), 1=>array(  'id'=>1002,  'username'=>'关羽',  'password'=>'123456',  'address'=>'三国时花果山' ), 2=>array(  'id'=>1003,  'username'=>'曹操',  'password'=>'123456',  'address'=>'延安西路2055弄3号' ), 3=>array(  'id'=>1004,  'username'=>'刘备',  'password'=>'654321',  'address'=>'愚园路188号3309室' ));$objPHPExcel=new PHPExcel();$objPHPExcel->getProperties()->setCreator('http://www.jb51.net')        ->setLastModifiedBy('http://www.jb51.net')        ->setTitle('Office 2007 XLSX Document')        ->setSubject('Office 2007 XLSX Document')        ->setDescription('Document for Office 2007 XLSX, generated using PHP classes.')        ->setKeywords('office 2007 openxml php')        ->setCategory('Result file');$objPHPExcel->setActiveSheetIndex(0)            ->setCellValue('A1','ID')            ->setCellValue('B1','用户名')            ->setCellValue('C1','密码')            ->setCellValue('D1','地址');$i=2;   foreach($data as $k=>$v){ $objPHPExcel->setActiveSheetIndex(0)            ->setCellValue('A'.$i,$v['id'])            ->setCellValue('B'.$i,$v['username'])            ->setCellValue('C'.$i,$v['password'])            ->setCellValue('D'.$i,$v['address']); $i++;}$objPHPExcel->getActiveSheet()->setTitle('三年级2班');$objPHPExcel->setActiveSheetIndex(0);$filename=urlencode('学生信息统计表').'_'.date('Y-m-dHis');/**生成xlsx文件header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');header('Content-Disposition: attachment;filename="'.$filename.'.xlsx"');header('Cache-Control: max-age=0');$objWriter=PHPExcel_IOFactory::createWriter($objPHPExcel,'Excel2007');*//**生成xls文件header('Content-Type: application/vnd.ms-excel');header('Content-Disposition: attachment;filename="'.$filename.'.xls"');header('Cache-Control: max-age=0');$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel,'Excel5');*/$objWriter->save('php://output');exit;//导入$this->load->library('PHPExcel');$this->load->library('PHPExcel/IOFactory');$config['upload_path'] = './excel/';$config['allowed_types'] = 'xls|xlsx|xl';$this->load->library('upload',$config);if ($this->upload->do_upload('img')) //原表名 { $file = $this->upload->data();$file_name = $file['file_name'];
