PHPExcel导出mysql数据库数据

使用PHPExcel导出文件

首先看看上面的文章，写入方法一样，只是中间多了数据库的操作，后面还有excel浏览器输出。

数据库代码（数据库配置文件自行完成）

<?php
/*db.php*/
	require dirname(__FILE__)."/dbconfig.php";

	class db{
		public $conn = null;

		public function __construct($config){
			$this->conn=mysql_connect($config['host'],$config['username'],$config['password']) or die(mysql_error());
			mysql_select_db($config['database'],$this->conn) or die(mysql_error());
			mysql_query("set names ".$config['charset']) or die(mysql_error());
		}

		public function getResult($sql){
			$resource = mysql_query($sql,$this->conn) or die(mysql_error());
			$res = array();
			while(($row=mysql_fetch_assoc($resource))!=false){
				$res[] = $row;
			}
			return $res;
		}

		public function getUserinfo(){
			$sql = "。。。";
			$res = self::getResult($sql);
			return $res;
		}
	}

数据库导出代码：

<?php
	$dir = dirname(__FILE__);
	require $dir."/db.php";
	require $dir."/PHPExcel.php";

	$db = new db($phpexcel);
	$objPHPExcel = new PHPExcel();

	for($i=0; $i<3; $i++){
		if($i>0){
			$objPHPExcel->createSheet();
		}
		$objPHPExcel->setActiveSheetIndex($i);
		$objSheet = $objPHPExcel->getActiveSheet();
		$data = $db->getUserinfo();

		$objSheet->setCellValue("A1","编号")->setCellValue("B1","登陆名")
				->setCellValue("C1","昵称")->setCellValue("D1","电子邮箱")
				->setCellValue("E1","学校")->setCellValue("F1","最后登陆时间");

		$j = 2;
		foreach ($data as $key => $value) {
			# code...
			$objSheet->setCellValue("A".$j,$value['id'])->setCellValue("B".$j,$value['user_login'])
					->setCellValue("C".$j,$value['user_nicename'])->setCellValue("D".$j,$value['user_email'])
					->setCellValue("E".$j,$value['sch_name'])->setCellValue("F".$j,$value['last_login_time']);
			$j++;
		}
	}

	$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel,"Excel5");
	// $objWriter->save($dir.'/export.xls'); //生成excel文件
	browser_export("Excel5","browser_excel03.xls"); //浏览器输出
	$objWriter->save("php://output");

	function browser_export($type, $filename){
		if($type == "Excel5"){
			header('Content-Type: application/vnd.ms-excel'); //excel2003
		}else{
			header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet'); //excel2007
		}
		header('Content-Disposition: attachment;filename="'.$filename.'"');
		header('Cache-Control: max-age=0');
	}
