PHPExcel导入excel数据到数据库中

绝地灬酷狼 2022-08-05 08:23 362阅读 0赞

以下内容是基于ThinkPHP框架。。

简述：导入的excel表格文件由四个工作表组成，其中前面三个工作表根据客户名称关联起来，它们共同构成数据库中12个表的每条数据，第四个工作表是独立的产品信息表。12个表都是关联表，含有其他表的外键。

数据库字段结构设计是全部不能为空，主键id都是自增。

1、总体实现思路

为每个数据库表创建一个数组来保存Excel表格中读取的数据，数组的键等于数据库字段名，数组的值等于excel对应的列的内容。先读取第一个工作表的数据，根据工作表行数增加来读取每条数据保存到数组中，然后使用

M()->add($data)方法添加数组到数据库中。通过PHPExcel类库中的$phpexcel->getSheet(0)方法可以读取每个工作表。

2、如何关联数据表的外键

TP中调用模型的add()方法添加数据成功后会返回插入的记录的主键id，保存该id。

一个客户名称存在于3个工作表的数据通过客户名称关联起来，也就是3个工作表中都有客户名称。所以插入其他工作表的数据到数据库时需要根据客户名称获得关联的表的主键。

$condition\[‘name’\] = $customer\_name;

$res = M(‘customer\_info’)->where($condition)->find();

$data\_procurement\_plan\[‘customer\_id’\] = $res\[‘id’\];//关联customer\_info表的id

3、添加相同的客户名称的记录

客户名称在客户信息表中是唯一存在的所以该字段设置唯一索引。Excel中含有数据库中已经存在的客户名称时更新记录，调用删除方法删除存在的12个表中的记录，再添加新记录。

4、excel有的列为空，但是数据库不能有空字段，设置默认值

定义一个函数对数组进行检查，有空的键给设默认值

public function setArrayDefault(&$arr)\{

foreach($arr a4 $k => $v)\{

arr\[$k\] = isset($v)?$v:’’;

return $arr;

5、数据库表中的每个字段在excel中都为空时，不插入该记录。例如无历史合作信息。

if( trim($data\_old\_cooperation\[‘cooperatiom\_time’\]) !== ‘’)

|| trim($data\_old\_cooperation\[‘cooperatiom\_type’\]) !== ‘’

|| trim($data\_old\_cooperation\[‘cooperatiom\_rank’\]) !== ‘’ )\{

// 添加记录代码

...

三个字段只要有一个有数据就插入，否则不插入。

trim() 函数是去除字符串两端的空格，防止excel中内容为空格的记录插入。

6、excel中的日期处理

很奇怪在excel中的日期2015-09-09在php代码中会变成42256,得不到正确的日期。

处理如下：首先在excel模版的有日期的列设置单元格格式，选中列头，右键->单元格格式->日期->格式码，设置为YYYY-MM-DD。

function formatData($data)\{

$data = trim($data);// 去除空格

if(empty($data)) return “0000-00-00”;

$n = intval(($data - 25569)\*3600\*24);// 转换成1970年以来的秒数

$format\_data = gmdata(‘Y-m-d’,$n);// 格式化的时间

return $format\_data;

$data 是从excel中读取的内容;

return “0000-00-00” 是设置自定义的默认值，如果excel内容为空的话，插入到数据库中得到的结果是1899-12-30,该值是输入日期为空时的默认时间。

注意事项：

1、数据库字段名称统一用小写，代码中字段名要可数据库中的大小写对应，否则可能插入数据失败。

2、PHPExcel插件放在Public目录下，没找到已经定义的指向public文件的路径，所以在index.php中定义了PUBLIC\_PATH的路径。
