tp5的excel导出功能

使用composer安装phpexcel包

composer require phpoffice/phpexcel

然后在common.php文件写个导出excel的函数

/**

 * excel表格导出

 * @param string $fileName 文件名称

 * @param array $headArr 表头名称

 * @param array $data 要导出的数据

 * @author static7  */

function excelExport($fileName = '', $headArr = [], $data = []) {

    $fileName .= "_" . date("Y_m_d", Request::instance()->time()) . ".xls";

    $objPHPExcel = new \PHPExcel();

    $objPHPExcel->getProperties();

    $key = ord("A"); // 设置表头

    foreach ($headArr as $v) {

        $colum = chr($key);

        $objPHPExcel->setActiveSheetIndex(0)->setCellValue($colum . '1', $v);

        $objPHPExcel->setActiveSheetIndex(0)->setCellValue($colum . '1', $v);
        
        //下面注释的这行代码是让表头拥有筛选功能，根据需要取消注释即可

        //$objPHPExcel->getActiveSheet()->setAutoFilter($objPHPExcel->getActiveSheet()->calculateWorksheetDimension());


        $key += 1;

    }

    $column = 2;

    $objActSheet = $objPHPExcel->getActiveSheet();

    foreach ($data as $key => $rows) { // 行写入

        $span = ord("A");

        foreach ($rows as $keyName => $value) { // 列写入

            $objActSheet->setCellValue(chr($span) . $column, $value);

            $span++;

        }

        $column++;

    }

    $fileName = iconv("utf-8", "gb2312", $fileName); // 重命名表

    $objPHPExcel->setActiveSheetIndex(0); // 设置活动单指数到第一个表,所以Excel打开这是第一个表

    header('Content-Type: application/vnd.ms-excel');

    header("Content-Disposition: attachment;filename='$fileName'");

    header('Cache-Control: max-age=0');

    $objWriter = \PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5');

    $objWriter->save('php://output'); // 文件通过浏览器下载

    exit();

}

接着在控制器里写一个测试导出excel的方法

/**

 * tp5 使用excel导出

 * @param

 * @author staitc7  * @return mixed

 */

public function excel() {

   $name='测试导出';

   $header=['表头A','表头B'];

   $data=[

       ['嘿嘿','heihei'],

       ['哈哈','haha']

   ];

   excelExport($name,$header,$data);

}

最后调用excel方法
