PHPExcel：在“ 01simple-download-xls.php”示例上使用MySQLi查詢

Question

有人會知道有人采用PHPExcel的“ 01simple-download-xls.php”並對其進行修改以與MySQLi查詢一起使用的一個好例子嗎？ 我一直在尋找一個好的例子方面遇到一些麻煩。

我想完整地保留示例中的所有內容，而只用MySQLi查詢替換這部分代碼（如下）。

看來我可以遍歷查詢並轉儲setCellValue（我認為）。 我一直在嘗試找到一種更優雅的解決方案，其中（不知道所涉及的列數）該代碼可以在不做任何修改的情況下適用於任何查詢。

因此，我只想替換此示例的一部分：

// Add some data
$objPHPExcel->setActiveSheetIndex(0)
            ->setCellValue('A1', 'Hello')
            ->setCellValue('B2', 'world!')
            ->setCellValue('C1', 'Hello')
            ->setCellValue('D2', 'world!');

// Miscellaneous glyphs, UTF-8
$objPHPExcel->setActiveSheetIndex(0)
            ->setCellValue('A4', 'Miscellaneous glyphs')
            ->setCellValue('A5', 'éàèùâêîôûëïüÿäöüç');

這是PHPExcel示例（01simple-download-xls.php）中包含的完整示例文件：

Answer 1

在此處下載PHPExcel ，然后嘗試以下代碼。

$sql = mysqli_query($conn, "SELECT id FROM invoice_product WHERE model_name = '$mname' && model_no = '$mno' ORDER BY color");
$a=0;
while ($result = mysqli_fetch_array($sql))
{
    $id_array[$a] = $result[id];
    $a++;
}

$sql2 = mysqli_query($conn, "SELECT * FROM invoice_imei WHERE invoice_product_id IN (".implode(',',$id_array).")");

$setExcelName = "IMEI"; 

require_once '../PHPExcel/Classes/PHPExcel/IOFactory.php';
require_once '../PHPExcel/Classes/PHPExcel.php';

// Create new PHPExcel object
$objPHPExcel = new PHPExcel(); 

//setting column heading
$objPHPExcel->getActiveSheet()->setCellValue('A1',"Model Name"); 
$objPHPExcel->getActiveSheet()->setCellValue('B1',"Model No."); 
$objPHPExcel->getActiveSheet()->setCellValue('C1',"Color"); 
$objPHPExcel->getActiveSheet()->setCellValue('D1',"IMEI"); 
$objPHPExcel->getActiveSheet()->setCellValue('E1',"Status"); 

//setting column body
$i=2; //starting from row 2 bcz row 1 set to header
while ($result2 = mysqli_fetch_array($sql2)) {
    $sql3 = mysqli_query($conn, "SELECT color FROM invoice_product WHERE id = '$result2[invoice_product_id]'"); 
    $result3 = mysqli_fetch_assoc($sql3);

    $objPHPExcel->getActiveSheet()->setCellValue('A'.$i,$mname);
    $objPHPExcel->getActiveSheet()->setCellValue('B'.$i,$mno);
    $objPHPExcel->getActiveSheet()->setCellValue('C'.$i,$result3[color]);
    $objPHPExcel->getActiveSheet()->setCellValue('D'.$i,$result2[imei]);
    if ($result2[status] == 0) { 
        $objPHPExcel->getActiveSheet()->setCellValue('E'.$i,'Not Used');
    } else {
        $objPHPExcel->getActiveSheet()->setCellValue('E'.$i,'Used');
    }
    $i++;
}
// Redirect output to a client’s web browser (Excel5)
header('Content-type: application/xlsx');
header('Content-Disposition: attachment;filename="IMEI.xls"');
header('Cache-Control: max-age=0');

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

$objWriter->save('php://output');
exit;

Answer 2

您可以利用工作表的fromArray()方法將數組中的一行單元格設置為單個調用，無論數組中有多少值，該行都將起作用：

$row=2;
while ($result = mysqli_fetch_row($queryResultSet)) {
    $objPHPExcel->getActiveSheet()
        ->fromArray($result, null, 'A'.$row++);
}
