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
