导入/导出excel和PHPExcel基本使用

* PHPExcel基本使用

* PS:文章如果有误,请及时指出,给予修改

* 项目中导入PHPExcel

* 可以去网上下载 github composer 都可以

* 为了方便下载,我将压缩包添加到了百度云  下面是地址和提取密码

* 链接:https://pan.baidu.com/s/10eaZ0-Ij6kd4jriP3QOABA 提取密码:enwi

* 踩的坑:

* 坑1:excel的单元格读取的值 可能是空字符串 使用empty()函数进行判断 返回值为true 使用时先进行trim();

* 坑2:excel单元格的值若是函数计算出的值 读取出来无法进行直接使用 需要判断

* 坑3:getOldCalculatedValue 和 getCalculatedValue , getCalculatedValue()这个方法已经不推荐使用了

         $value = $objPHPExcel->getActiveSheet()->getCell($column.$row)->getValue();

         if(substr($value,0,1) == '='){

                $value = $objPHPExcel->getActiveSheet()->getCell($column.$row)->getOldCalculatedValue();

          }

* 坑4:如果当前excel数据列数超过Z列,后续AA,AB ... 此时循环需要自己手动处理循环列数 则不能再使用 ++ 完成自动运算

* 坑5:导出默认会自己创建一个sheet,如果需要导出多个sheet,在第一个sheet后再执行 $objPHPExcel->createSheet();

* 坑6:设置单元格不以科学技术法显示不生效,强制将数字字符串转换为字符串,拼接空格即可

* 坑7:不要闲麻烦,每个取值和不确定的数据 都使用isset()进行判断 ,很有可能当前取得列,其他sheet页没有

* 坑8:最好在方法开始的最外层,增加异常的捕获.不然程序异常影响用户体验

* 坑9:在require引入PHPExcel扩展的时候,确保文件夹有可读权限

* excel文件上传 : 由于无法在上传的时候 直接读取文件的值 只有先将文件存储后使用  使用完成后删除即可[使用:unlink()]

* laravel 框架自带文件存储 使用也相当简单

$request = new Request();

* 两种存储文件方式 store 和 storeAs

* store 方法接受相对于文件系统配置的存储文件根目录的路径。这个路径不能包含文件名，因为系统会自动生成唯一的 ID 作为文件名。

* 该方法还接受可选的第二个参数，用于存储文件的磁盘名称。这个方法会返回相对于磁盘根目录的文件路径

$path = $request->file->store('xxx');

$path = $request->file->store('xxx', 's3');

* storeAs 方法，它接受路径、文件名和磁盘名

$path = $request->file->storeAs($save_path, $tmpName);

* 解释为什么中间为file 是因为传递参数 name为file 如果是其他 则换为传递的name即可

* storeAs只能将文件存储到storage文件夹下 如果要自定义文件存储除storage以外的路径

* 使用PHP原生处理文件机制:move_uploaded_file 若成功，则返回 true，否则返回 false。

$bool = move_uploaded_file($_FILES["file"]["tmp_name"], '$save_path);//$save_path 为文件写入路径

*

* 使用:

* 项目中引用路径

require_once './PHPExcel/PHPExcel.php';

* 导出:PHPExcel实例化对象

* 导入:PHPExcel_IOFactory实例化对象

$objPHPExcel = new PHPExcel(); 

$objPHPExcel = \PHPExcel_IOFactory::load($path); //$path为excel文件绝对路径
