tp5.1/thinkPHP5.1/TP5.1 composer安装和使用PHPExcel

一.windows本地环境composer安装PHPExcel
首先：下载安装composer
其次 cmd切换到项目根目录 运行命令：composer require phpoffice/phpexcel
注意：
        1.运行可能会报错OpenSSL之类的 去php.ini中开启extension=php_openssl.dll扩展，去掉分号
        2.还有可能出现 找不到匹配的包的错误，这是因为我本地用的phpstudy的nts版本，这个版本比较特殊同时支持apache和nginx，只是本地虚拟环境开发测试用的PHP版本，所以匹配不到，应该切换正常版本在运行命令安装



    3.composer只支持php5.6以上版本

出现下图说明已经安装成功了



二、使用phpexcel
composer安装的phpexcel
只需要在头部use PHPExcel;
然后创建一个对象$objExcel = new \PHPExcel();
这样就可以使用了





三、
我直接封装了一个方法，只需要把要导出的数据的数组传进来，然后改一些字段和文案就可以了
function daysales_excel($driver){
//导出表格
$objExcel = new \PHPExcel();
$objWriter = \PHPExcel_IOFactory::createWriter($objExcel, 'Excel5');
// 设置水平垂直居中
$objExcel->getActiveSheet()->getDefaultStyle()->getAlignment()->setHorizontal(\PHPExcel_Style_Alignment::HORIZONTAL_CENTER);
$objExcel->getActiveSheet()->getDefaultStyle()->getAlignment()->setVertical(\PHPExcel_Style_Alignment::VERTICAL_CENTER);
// 字体和样式
$objExcel->getActiveSheet()->getDefaultStyle()->getFont()->setSize(10);
$objExcel->getActiveSheet()->getStyle('A2:AB2')->getFont()->setBold(true);
$objExcel->getActiveSheet()->getStyle('A1')->getFont()->setBold(true);
// 第一行、第二行的默认高度
$objExcel->getActiveSheet()->getRowDimension('1')->setRowHeight(30);
$objExcel->getActiveSheet()->getRowDimension('2')->setRowHeight(20);
//设置某一列的宽度
$objExcel->getActiveSheet()->getColumnDimension('A')->setWidth(10);
$objExcel->getActiveSheet()->getColumnDimension('B')->setWidth(15);
$objExcel->getActiveSheet()->getColumnDimension('C')->setWidth(20);
$objExcel->getActiveSheet()->getColumnDimension('D')->setWidth(10);
$objExcel->getActiveSheet()->getColumnDimension('E')->setWidth(5);
$objExcel->getActiveSheet()->getColumnDimension('F')->setWidth(30);
$objExcel->getActiveSheet()->getColumnDimension('G')->setWidth(30);
$objExcel->getActiveSheet()->getColumnDimension('H')->setWidth(15);

//设置表头
//  合并
$objExcel->getActiveSheet()->mergeCells('A1:I1');
$objActSheet = $objExcel->getActiveSheet(0);
$objActSheet->setTitle('用户统计');//设置excel的标题
$objActSheet->setCellValue('A1','日销售额统计');
$objActSheet->setCellValue('A2','标的名称');
$objActSheet->setCellValue('B2','标的金额');
$objActSheet->setCellValue('C2','标的利率(%)');
$objActSheet->setCellValue('D2','标的上线时间');
$objActSheet->setCellValue('E2','募集天数');
$objActSheet->setCellValue('F2','实际募集金额(元)');
$objActSheet->setCellValue('G2','超过部分');
$objActSheet->setCellValue('H2','融资人');

$baseRow = 3; //数据从N-1行开始往下输出 这里是避免头信息被覆盖
foreach ( $driver as $r => $d ) {
$i = $baseRow + $r;
$objExcel->getActiveSheet()->setCellValue('A'.$i,$d['title']);
$objExcel->getActiveSheet()->setCellValue('B'.$i,$d['amount']);
$objExcel->getActiveSheet()->setCellValue('C'.$i,$d['user_interest_rate']);
$objExcel->getActiveSheet()->setCellValue('D'.$i,$d['start_time']);
$objExcel->getActiveSheet()->setCellValue('E'.$i,''.$d['duration_collect']);
$objExcel->getActiveSheet()->setCellValue('F'.$i,$d['daysales_amount']);
$objExcel->getActiveSheet()->setCellValue('G'.$i,$d['amount']-$d['daysales_amount']);
$objExcel->getActiveSheet()->setCellValue('H'.$i,$d['debit_name']);
}

$objExcel->setActiveSheetIndex(0);
//4、输出
$objExcel->setActiveSheetIndex();
header('Content-Type: applicationnd.ms-excel');
$time=date('YmdHis');
header("Content-Disposition: attachment;filename=用户统计$time.xls");
header('Cache-Control: max-age=0');
$objWriter->save('php://output');
}
