【问题描述】：

我有评论计数的用户列表。我有使用下面的库和代码导出 excel。如何在 Excel 工作表中包含图表。

这是我的输出：例如：

Sno   USER     CommentCount
1     User1    10
2     User2    12
3     User3    21

如何使用 codeigniter 在 Excel 中形成图形或图表。

图书馆功能：

class Export{    
    function to_excel($array, $filename) {
        header('Content-type: application/vnd.ms-excel');
        header('Content-Disposition: attachment; filename='.$filename.'.xls');         
        $h = array();
        foreach($array as $row){
            foreach($row as $key=>$val){
                if(!in_array($key, $h)){
                    $h[] = $key;   
                }
            }
        }
        echo '<table><tr>';
        foreach($h as $key) {
            $key = ucwords($key);
            echo '<th>'.$key.'</th>';
        }
        echo '</tr>';
        foreach($array as $row){
            echo '<tr>';
            foreach($row as $val)
            $this->writeRow($val);   
        }
        echo '</tr>';
        echo '</table>';
    }
    function writeRow($val) {
        echo '<td>'.utf8_decode($val).'</td>';              
    }
}

控制器代码：

public function userlist(){      
    $sql = $this->export_model->user_export();      
    $this->export->to_excel($sql, 'UserList'); 
}

最后我使用 PHP EXCEL 得到了它。代码如下

include "Classes/PHPExcel.php";
    header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');
    header('Content-Disposition: attachment;filename="graphdemo.xlsx"');
    header('Cache-Control: max-age=0');
    $workbook = new PHPExcel();

    $objRichText = new PHPExcel_RichText();
    $objBold = $objRichText->createTextRun('Name');
    $objBold->getFont()->setBold(true);
    $workbook->getActiveSheet()->getCell('A1')->setValue($objRichText);

    $objRichText = new PHPExcel_RichText();
    $objBold = $objRichText->createTextRun('Sharing Count');
    $objBold->getFont()->setBold(true);
    $workbook->getActiveSheet()->getCell('B1')->setValue($objRichText);  

    $workbook->setActiveSheetIndex(0);
    $sheet = $workbook->getActiveSheet();
    $sheet->getPageMargins()->setTop(0.6);
    $sheet->getPageMargins()->setBottom(0.6);
    $sheet->getPageMargins()->setHeader(0.4);
    $sheet->getPageMargins()->setFooter(0.4);
    $sheet->getPageMargins()->setLeft(0.4);
    $sheet->getPageMargins()->setRight(0.4);
    $workbook->getProperties()->setTitle("Demo");
    $workbook->getProperties()->setCreator("Demo");
    $workbook->getProperties()->setLastModifiedBy("Demo");
    $workbook->getProperties()->setCompany("Demo");


    $Requete = "SELECT  COUNT(*) As cnt , name FROM `users` GROUP BY  user_id  ";
    $result  = mysql_query($Requete);  
    while ($row = mysql_fetch_array($result)){   
        $bname[] = $row["name"];
        $bk_co[] = $row["cnt"];         
    } 
    $data =$bname;  
    $row = 2;
    foreach($data as $point) {
        $sheet->setCellValueByColumnAndRow(0, $row++, $point);
    }    
    $data = $bk_co;
    $row = 2;
    foreach($data as $point) {
        $sheet->setCellValueByColumnAndRow(1, $row++, $point);
    }

    $values = new PHPExcel_Chart_DataSeriesValues('Number', 'Worksheet!$B$1:$B$10');
    $categories = new PHPExcel_Chart_DataSeriesValues('String', 'Worksheet!$A$1:$A$10');
    $series = new PHPExcel_Chart_DataSeries(
    PHPExcel_Chart_DataSeries::TYPE_BARCHART,        
    PHPExcel_Chart_DataSeries::GROUPING_CLUSTERED,   
    array(0),                                        
    array(),                                         
    array($categories),                             
    array($values)                                   
    );
    $series->setPlotDirection(PHPExcel_Chart_DataSeries::DIRECTION_COL);
    $layout = new PHPExcel_Chart_Layout();
    $plotarea = new PHPExcel_Chart_PlotArea($layout, array($series));
    $chart = new PHPExcel_Chart('sample', null, null, $plotarea);
    $chart->setTopLeftPosition('F2');
    $chart->setBottomRightPosition('N25');
    $sheet->addChart($chart);
    $writer = PHPExcel_IOFactory::createWriter($workbook, 'Excel2007');
    $writer->setIncludeCharts(TRUE);
    $writer->save('php://output');
