PHP 利用PHPExcel類庫批量導出數據

以前作健康檔案系統時，有一個將統計的數據批量導出到Excel的需求，後來實現後就沒怎麼作記錄，最近一個小夥伴問我這塊的問題，我以爲有必要將這塊的東西寫下來和你們分享和學習下，這段時間真的是太忙了，因此博客這塊也沒能及時更新，望見諒。

下面進入正題，在需求這塊，有一個統計展現，統計出按條件搜索出來的全部信息，如今是要將這些數據都導入到Excel表格中，方便給領導看須要的數據。我這塊的思路是首先獲取表頭的數據，獲取數據庫中對應的數據信息，注意這塊的數據要和表頭的信息是對應的，而後根據表頭信息數量來肯定插入的數據量，設置部分Excel表格樣式，最後是經過瀏覽器輸出給用戶。

下面是部分代碼段，因爲時間關係，我只解釋部分代碼段

    

//生成excle文件
function generateExcel($param){
    $objExcel = new PHPExcel();
    $i=0;
    //表頭
    $k1="民警編號";
    $k2="民警姓名";
    $k3="性別";
    $k4="出生日期";
    $k5="部門";
    $k6="體檢時間";
    $k7="住院時間";
    $k8="出院時間";
    $k9="病種";
    $k10="殘疾情況";
    $k11="受傷時間";
    $k12="培訓時間";
    $k13="培訓結果";
    $k14="資質級別";

    $objExcel->getActiveSheet()->setCellValue('a1', "$k1");
    $objExcel->getActiveSheet()->setCellValue('b1', "$k2");
    $objExcel->getActiveSheet()->setCellValue('c1', "$k3");
    $objExcel->getActiveSheet()->setCellValue('d1', "$k4");
    $objExcel->getActiveSheet()->setCellValue('e1', "$k5");
    $objExcel->getActiveSheet()->setCellValue('f1', "$k6");
    $objExcel->getActiveSheet()->setCellValue('g1', "$k7");
    $objExcel->getActiveSheet()->setCellValue('h1', "$k8");
    $objExcel->getActiveSheet()->setCellValue('i1', "$k9");
    $objExcel->getActiveSheet()->setCellValue('j1', "$k10");
    $objExcel->getActiveSheet()->setCellValue('k1', "$k11");
    $objExcel->getActiveSheet()->setCellValue('l1', "$k12");
    $objExcel->getActiveSheet()->setCellValue('m1', "$k13");
    $objExcel->getActiveSheet()->setCellValue('n1', "$k14");

    $policehealthstatistics = new Policehealth_statistics();
    $links_list = $policehealthstatistics->getConditionInformationExcle($param);
 
    foreach($links_list as $k=>$v) {
        $u1=$i+2;
        /*----------寫入內容-------------*/
        $objExcel->getActiveSheet()->setCellValue('a'.$u1, $v["policenum"]);
        $objExcel->getActiveSheet()->setCellValue('b'.$u1, $v["realname"]);
        $objExcel->getActiveSheet()->setCellValue('c'.$u1, $v["sex"]);
        $objExcel->getActiveSheet()->setCellValue('d'.$u1, $v["csrq"]);
        $objExcel->getActiveSheet()->setCellValue('e'.$u1, $v["department"]);
        $objExcel->getActiveSheet()->setCellValue('f'.$u1, $v["tjsj"]);
        $objExcel->getActiveSheet()->setCellValue('g'.$u1, $v["zysj"]);
        $objExcel->getActiveSheet()->setCellValue('h'.$u1, $v["cysj"]);
        $objExcel->getActiveSheet()->setCellValue('i'.$u1, $v["bz"]);
        $objExcel->getActiveSheet()->setCellValue('j'.$u1, $v["cjjb"]);
        $objExcel->getActiveSheet()->setCellValue('k'.$u1, $v["sssj"]);
        $objExcel->getActiveSheet()->setCellValue('l'.$u1, $v["pxsj"]);
        $objExcel->getActiveSheet()->setCellValue('m'.$u1, $v["pxjg"]);
        $objExcel->getActiveSheet()->setCellValue('n'.$u1, $v["zzjb"]);
        $i++;
    }

// 高置列的寬度
    $objExcel->getActiveSheet()->getColumnDimension('A')->setWidth(15);
    $objExcel->getActiveSheet()->getColumnDimension('B')->setWidth(15);
    $objExcel->getActiveSheet()->getColumnDimension('C')->setWidth(15);
    $objExcel->getActiveSheet()->getColumnDimension('D')->setWidth(15);
    $objExcel->getActiveSheet()->getColumnDimension('E')->setWidth(35);
    $objExcel->getActiveSheet()->getColumnDimension('F')->setWidth(15);
    $objExcel->getActiveSheet()->getColumnDimension('G')->setWidth(15);
    $objExcel->getActiveSheet()->getColumnDimension('H')->setWidth(15);
    $objExcel->getActiveSheet()->getColumnDimension('I')->setWidth(15);
    $objExcel->getActiveSheet()->getColumnDimension('J')->setWidth(15);
    $objExcel->getActiveSheet()->getColumnDimension('K')->setWidth(15);
    $objExcel->getActiveSheet()->getColumnDimension('L')->setWidth(15);
    $objExcel->getActiveSheet()->getColumnDimension('M')->setWidth(15);
    $objExcel->getActiveSheet()->getColumnDimension('N')->setWidth(35);

    $objExcel->getActiveSheet()->getHeaderFooter()->setOddHeader('&L&BPersonal cash register&RPrinted on &D');
    $objExcel->getActiveSheet()->getHeaderFooter()->setOddFooter('&L&B' . $objExcel->getProperties()->getTitle() . '&RPage &P of &N');

// 設置頁方向和規模
    $objExcel->getActiveSheet()->getPageSetup()->setOrientation(PHPExcel_Worksheet_PageSetup::ORIENTATION_PORTRAIT);
    $objExcel->getActiveSheet()->getPageSetup()->setPaperSize(PHPExcel_Worksheet_PageSetup::PAPERSIZE_A4);
    $objExcel->setActiveSheetIndex(0);
    $timestamp = time();
//導出excel2007文檔
//    header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');
//    header('Pragma:public');
    /*header("Content-Type: application/force-download");
    header('Content-Disposition: attachment;filename="links_out'.$timestamp.'.xlsx"');
    header('Cache-Control: max-age=0');*/

    ob_end_clean();//清除緩衝區,避免亂碼
    header('Content-Type: application/vnd.ms-excel');
    header('Content-Disposition: attachment;filename="詳情表(' . date('Ymd-His') . ').xls"');
    header('Cache-Control: max-age=0');
    $objWriter = PHPExcel_IOFactory::createWriter($objExcel, 'Excel2007');
//    $fileName = "111.xlsx";
    $objWriter->save('php://output');
    exit;

因爲表頭這塊以前是固定的格式，因此我沒有用動態獲取的方式來處理，經過$objExcel->getActiveSheet()->setCellValue('a'.$u1, $v["policenum"]);將從數據庫中提取出的信息寫入到Excel中，這塊有個注意點在setCellValue中的第一個參數不能同名，由於這塊是給表格作標識，同名後會致使後面的數據覆蓋前面的數據。後面的設置表格樣式你們能夠去體會，就是對象調用方法的問題，主要說下最後的那個輸出方式。$fileName = "111.xlsx";是將生成好的excle文件命名爲111.xlsx並輸出到當前文件目錄中，若是用$objWriter->save('php://output');則是在瀏覽器窗口中輸出。以前我卡在無法在瀏覽器中進行輸出excle文件，因爲時間有點久了，具體的緣由如今記得不太清楚了，好像是傳給前端是json數據，致使後面文件一直沒有出來。

若有說的錯誤或不許確的地方，但願你們指正
