PHPExcel：在'01simple-download-xls.php'上使用MySQLi查詢例如

Question

是否有人會知道有人採用PHPExcel的「01simple-download-xls.php」並將其修改爲與MySQLi查詢？我一直在找一個好的工作例子遇到一些麻煩。

我想保留示例中的所有內容，只需用MySQLi查詢替換這部分代碼（下面）。

它看起來像我可以循環查詢並轉儲setCellValue（我認爲）。我一直在試圖找到一個更優雅的解決方案，其中（不知道涉及的列數）代碼可以適用於任何查詢而無需修改。

所以，我想只需更換這一塊的例子：

// 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'); 

這是包括PHPExcel樣品（01simple下載-xls.php）在完整的示例文件：

下載PHPExcel here並嘗試下面的代碼。

$sql = mysqli_query($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;

您可以利用工作表的fromArray()方法來從一個數組作爲一個單一的呼叫建立單元行，不管有多少值在數組中，將工作：

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