如何使用thinkphp导出excel

第一，先查出数据库里面要生成Excel的数据，如：
$data= M('User')->findAll(); //查出数据$name='Excelfile'; //生成的Excel文件文件名$res=service('ExcelToArrary')->push($data,$name);
第二，ExcelToArrary类,用来引用phpExcel并处理数据的
class ExcelToArrary extends Service{public function __construct() {/*导入phpExcel核心类 注意 ：你的路径跟我不一样就不能直接复制*/include_once('./Excel/PHPExcel.php');}/* 导出excel函数*/public function push($data,$name='Excel'){error_reporting(E_ALL);date_default_timezone_set('Europe/London');$objPHPExcel = new PHPExcel();$objPHPExcel->getProperties()->setCreator("php爱好者")->setLastModifiedBy("php爱好者")->setTitle("数据EXCEL导出")->setSubject("数据EXCEL导出")->setDescription("备份数据")->setKeywords("excel")->setCategory("result file");foreach($data as $k => $v){$num=$k+1;$objPHPExcel->setActiveSheetIndex(0)//Excel的第A列，uid是你查出数组的键值，下面以此类推->setCellValue('A'.$num, $v['uid'])->setCellValue('B'.$num, $v['email'])->setCellValue('C'.$num, $v['password'])}$objPHPExcel->getActiveSheet()->setTitle('User');$objPHPExcel->setActiveSheetIndex(0);header('Content-Type: application/vnd.ms-excel');header('Content-Disposition: attachment;filename="'.$name.'.xls"');header('Cache-Control: max-age=0');$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5');$objWriter->save('php://output');exit;}
