PHPexcel的用法

由于经常要统计学生的考试成绩，就研究了下PHPexcel这个插件

顺便说一下,读取方法只针对xls文件。

如果报错，可以先生存一个xls文件，把需要读取的xls内容复制进去。

<?php  
　　　　　//读取excel文件
        header("Content-type:text/html;charset=utf-8");
        include 'Classes/PHPExcel/IOFactory.php'; 

        function  __construct(){
            include_once('Classes/PHPExcel.php');
        }

        function read ($filename){
            $objReader=PHPExcel_IOFactory::createReader('Excel5');

            $objReader->setReadDataOnly(true);
            $objPHPExcel = $objReader->load($filename);
            $objWorksheet = $objPHPExcel->getActiveSheet();
            $highestRow = $objWorksheet->getHighestRow();
            $highestColumn = $objWorksheet->getHighestColumn();
            $highestColumnIndex = PHPExcel_Cell::columnIndexFromString($highestColumn); 

            $excelData = array();
            for ($row = 1; $row <= $highestRow; $row++) {
                 for ($col = 0; $col < $highestColumnIndex; $col++) {
                    $excelData[$row][] =(string)$objWorksheet->getCellByColumnAndRow($col, $row)->getValue();
                }
            }

            return $excelData;
        }
        $result= read('1.xls');
        var_dump($result);
