PHP导入Excel表

初始化参数，先导入PHPExcel类

/**
 * 读出Excel表格数据
 * @param $filename  文件名
 * @param string $encode  编码格式
 * @return array   Excel数据
 * @throws PHPExcel_Reader_Exception
 */
function read($filename, $encode = 'utf-8')
{
    require_once './PHPExcel/IOFactory.php';
    $objPHPExcelReader = PHPExcel_IOFactory::load($filename);

    $reader = $objPHPExcelReader->getWorksheetIterator();
    //循环读取sheet
    foreach($reader as $sheet) {
        //读取表内容
        $content = $sheet->getRowIterator();
        //逐行处理
        $res_arr = array();
        foreach($content as $key => $items) {
            $rows = $items->getRowIndex();              //行
            $columns = $items->getCellIterator();       //列
            $row_arr = array();
            //确定从哪一行开始读取
            if($rows < 2){
                continue;
            }
            //逐列读取
            foreach($columns as $head => $cell) {
                //获取cell中数据
                $data = $cell->getValue();
                $row_arr[] = $data;
            }
            $res_arr[] = $row_arr;
        }
        return $res_arr;
    }

}

if (!empty($_FILES['file_stu']['name'])) {
    $tmp_file = $_FILES ['file_stu'] ['tmp_name'];
    $file_types = explode(".", $_FILES ['file_stu'] ['name']);
    $file_type = $file_types [count($file_types) - 1];
    /*判别是不是.xls文件，判别是不是excel文件*/
    if (strtolower($file_type) != "xls") {
        echo '不是Excel文件，重新上传';
    }
    /*设置上传路径*/
    $savePath = './excel/';
    /*以时间来命名上传的文件*/
    $str = date('Ymdhis');
    $file_name = $str . "." . $file_type;

    /*是否上传成功*/
    if (!copy($tmp_file, $savePath . $file_name)) {
        echo '上传失败';
    }
    $res = read($savePath . $file_name);
}else{
            echo  "读取失败";
}
