php导出导入excel 文件

php 导入导出excel  需要加载excel 类库

ps :如果导出文件打不开时,要检查一下php.ini 中

在php.ini文件中,将extension=php_zip.dll前面的分号“;”去除,然后同样在php.ini文件中,将 zlib.output_compression = 

Off 改为 zlib.output_compression = On ;


public function outexecl()
{
$_POST = $_GET;
$_POST = str_replace('\\','',$_POST) ;
$result = array(
0=>array('类别0','代码0','姓名0','名称0','缴纳地0') ,
1=>array('类别1','代码1','姓名1','名称1','缴纳地1') ,
2=>array('类别2','代码2','姓名2','名称2','缴纳地2') ,
3=>array('类别3','代码3','姓名3','名称3','缴纳地3') ,
4=>array('类别4','代码4','姓名4','名称4','缴纳地4') ,
