phpexcel excel数据导入到数据库

最近做项目遇到要把excel表格的数据导入到mysql数据库里面，一直报错：文件不存在或不可读，经过一下午的排错，终于弄好了，不多说了，直接贴代码：

function impUser(){
ini_set(‘memory_limit‘,‘1024M‘);
if (!empty($_FILES)) {
$config = array(
‘exts‘ => array(‘xlsx‘,‘xls‘),
‘maxSize‘ => 3145728000,
‘rootPath‘ =>"./Public/",
‘savePath‘ => ‘Uploads/‘,
‘subName‘ => array(‘date‘,‘Ymd‘),
);
$upload = new \Think\Upload($config);
if (!$info = $upload->upload()) {
$this->error($upload->getError());
}
vendor("PHPExcel.PHPExcel");
$file_name=$upload->rootPath.$info[‘photo‘][‘savepath‘].$info[‘photo‘][‘savename‘];
$extension = strtolower(pathinfo($file_name, PATHINFO_EXTENSION));//判断导入表格后缀格式
if ($extension == ‘xlsx‘) {
$objReader =\PHPExcel_IOFactory::createReader(‘Excel2007‘);
$objPHPExcel =$objReader->load($file_name, $encode = ‘utf-8‘);
} else if ($extension == ‘xls‘){
$objReader =\PHPExcel_IOFactory::createReader(‘Excel5‘);
$objPHPExcel =$objReader->load($file_name, $encode = ‘utf-8‘);
}
$sheet =$objPHPExcel->getSheet(0);
$highestRow = $sheet->getHighestRow();//取得总行数
$highestColumn =$sheet->getHighestColumn(); //取得总列数
D(‘Expert‘)->execute(‘truncate table qw_expert‘);
for ($i = 2; $i <= $highestRow; $i++) {
//看这里看这里,前面小写的a是表中的字段名，后面的大写A是excel中位置
$data[‘id‘] =$objPHPExcel->getActiveSheet()->getCell("A" . $i)->getValue();
$data[‘name‘] =$objPHPExcel->getActiveSheet()->getCell("B" .$i)->getValue();
$data[‘sex‘] =$objPHPExcel->getActiveSheet()->getCell("C" .$i)->getValue();
$data[‘thumbnail‘] = $objPHPExcel->getActiveSheet()->getCell("D". $i)->getValue();
$data[‘workunit‘] =$objPHPExcel->getActiveSheet()->getCell("E" . $i)->getValue();
$data[‘phone‘] =$objPHPExcel->getActiveSheet()->getCell("F" .$i)->getValue();
$data[‘sex‘] =$objPHPExcel->getActiveSheet()->getCell("G" .$i)->getValue();
$data[‘email‘] = $objPHPExcel->getActiveSheet()->getCell("H". $i)->getValue();
$data[‘research‘] =$objPHPExcel->getActiveSheet()->getCell("I" . $i)->getValue();
$data[‘sort‘] =$objPHPExcel->getActiveSheet()->getCell("J" .$i)->getValue();
$data[‘time‘] =$objPHPExcel->getActiveSheet()->getCell("K" .$i)->getValue();

//看这里看这里,这个位置写数据库中的表名

D(‘Expert‘)->add($data);
}
$this->success(‘导入成功!‘);
} else {
$this->error("请选择上传的文件");
}



}

说明：1、

          2、下载phpexcel 

         3、要和数据的字段一致。
