// 自动减去头部

//输出到临时缓冲区 提供下载
header ( "Content-Type: application/force-download" );
header ( "Content-Type: application/octet-stream" );
header ( "Content-Type: application/download" );
header ( 'Content-Disposition:inline;filename="'.$this->fileName.'"' );
header ( "Content-Transfer-Encoding: binary" );
header ( "Cache-Control: must-revalidate, post-check=0, pre-check=0" );
header ( "Pragma: no-cache" );
$objWriter = PHPExcel_IOFactory::createWriter ( $this->excelObj, 'Excel5' );
$objWriter->save ( 'php://output' );
}
/**
* 创建头部
*
* @param array $data
*/
private function createHeader($header, $keys) {
$header = array_combine ( $keys, $header );
foreach ( $header as $key => $vo ) {
$this->excelObj->setActiveSheetIndex ( 0 )->setCellValue ( "{$key}1", $vo );
}
}
}

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);
