使用示例:
$excel =new Excel();
$data=array(
array('id'=>1,'name'=>'天命1'),
array('id'=>2,'name'=>'天命2')
);
$header=array('ID','角色名');
$excel->setFileName('aaa');
$excel->setTitle('工作区1');
$excel->create($data,$header);也就是说,从数据库里拿出的二维数组可以直接创建,
另外,有的字段为type,保存为int类型的,代表某一个状态的.可以参考create第三个参数
举例:
$excel =new Excel();
$data=array(
array('id'=>1,'name'=>'天命1','type'=>1),
array('id'=>2,'name'=>'天命2','type'=>2)
);
$replace['type']=array(1=>'猛男',2=>'萌女');
$header=array('ID','角色名');
$excel->setFileName('aaa');
$excel->setTitle('工作区1');
$excel->create($data,$header,$replace);
