使用PHPExcel类库将数据导出为excel文档

下载PHPExcel类库，http://phpexcel.codeplex.com/，解压后在Class中找到PHPExcel文件夹和PHPExcel.php文件，拷贝到自己的项目代码中，以下是导出为excel文件的方法

<?php
function export_data() {
	require_once(‘PHPExcel.php‘);
	// 文档名称
	$filename = ‘filename‘;
	// 创建 PHPExcel 对象
	$objPHPExcel = new PHPExcel();
	// 设置生成的文档属性
	$objPHPExcel->getProperties()->setCreator("http://www.jianbin.info")
		->setLastModifiedBy("http://www.jianbin.info")
		->setTitle("http://www.jianbin.info")
		->setSubject("http://www.jianbin.info")
		->setDescription("http://www.jianbin.info")
		->setKeywords("http://www.jianbin.info")
		->setCategory("http://www.jianbin.info");

	$col_number = 65;
	$col_letter = chr($col_number);
	$row_number = 1;

	/**
	$table 数据格式
	array(
		‘head‘ => array(字段1,字段2,...,字段n),
		‘body‘ => array(
			‘行1‘ => (数据1,数据2,...,数据n),
			‘行2‘ => (数据1,数据2,...,数据n),
			...
			‘行n‘ => (数据1,数据2,...,数据n),
		)
	)
	 */

	foreach ($table[‘head‘] as $key=>$val){
		$objPHPExcel->setActiveSheetIndex(0)->setCellValue("{$col_letter}{$row_number}", $val);
		$objPHPExcel->getActiveSheet()->getColumnDimension("{$col_letter}")->setAutoSize(true);	// 自动列表设置对中文不支持

	}

	$row_number++;
	// 构造body
	foreach ($table[‘body‘] as $row){

			$col_number++;
			$col_letter = chr($col_number);
		}
		$row_number++;
	}
	// 重命名工作表
	$objPHPExcel->getActiveSheet()->setTitle($filename);
	// 默认打开工作表1
	$objPHPExcel->setActiveSheetIndex(0);

	// 设置header输出到客户端
	header(‘Content-Type: application/vnd.ms-excel‘);
	header(‘Content-Disposition: attachment;filename="‘.$filename.‘.xls"‘);
	header(‘Cache-Control: max-age=0‘);
	// If you‘re serving to IE 9, then the following may be needed
	header(‘Cache-Control: max-age=1‘);
	// If you‘re serving to IE over SSL, then the following may be needed
	header (‘Expires: Mon, 26 Jul 1997 05:00:00 GMT‘); // Date in the past
	header (‘Last-Modified: ‘.gmdate(‘D, d M Y H:i:s‘).‘ GMT‘); // always modified
	header (‘Cache-Control: cache, must-revalidate‘); // HTTP/1.1
	header (‘Pragma: public‘); // HTTP/1.0

	$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, ‘Excel5‘);
	$objWriter->save(‘php://output‘);
	exit;
}

导出后的文件打开效果如下：
