空白頁和沒有下載PHPExcel

我有這樣的代碼......

<?php 
session_start(); 
include 'dbconnect.php'; 
date_default_timezone_set("Europe/Rome"); 

if (!isset($_SESSION['user'])) { 
    header("Location: index.php"); 
} 
$query = mysql_query("SELECT * FROM partner1 WHERE uid=" . $_GET['id']); 
while ($userRow1 = mysql_fetch_assoc($query)) { 

    /** Error reporting */ 
    error_reporting(E_ALL); 
    ini_set('display_errors', TRUE); 
    ini_set('display_startup_errors', TRUE); 
    date_default_timezone_set('Europe/Rome'); 

    if (PHP_SAPI == 'cli') 
     die('This example should only be run from a Web Browser');

當我嘗試閱讀和下載我的數據庫中的數據爲Excel格式得到了一個空白頁面，並沒有下載。

我沒有得到任何錯誤。我不知道該怎麼辦笑

通常，當您最終出現空白頁面時，這是因爲您的代碼中存在錯誤並且錯誤報告已關閉。 – ThrowBackDewd

錯誤報告是TRUE隊友，即時通訊正在監視每一次刷新我的error_log –

我注意到的一件事是，你有你的while語句關閉在你的頁面的最後，但你的頭裏麪包括。這意味着你多次發送你的標題。我建議的另一件事是在這些行上使用for循環：$ objPHPExcel-> getActiveSheet（） - > getRowDimension（'1'） - > setRowHeight（40）;'。你所做的只是從1-27增加，所以你可以簡化代碼。 – ThrowBackDewd

明顯的問題

if(!isset($_SESSION['user'])) 
{ 
    header("Location: index.php"); 
}

仍將繼續執行你包括PHPExcel代碼

的其餘部分（只是這堵牆的代碼涉水）創建一個新的PHPExcel對象，併發送響應到瀏覽器中的每一行，同時$userRow1 = mysql_fetch_assoc($query))循環....我假設你真的想要將每一行寫入相同的文件

編輯

試圖保持答案簡單，而不是代碼的牆，你的結構應該是這樣的：

include 'dbconnect.php'; 

/** Include PHPExcel */ 
require_once dirname(__FILE__) . '/Classes/PHPExcel.php'; 

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

$query=mysql_query("SELECT * FROM partner1 WHERE uid=".$_GET['id']); 

while($userRow1 = mysql_fetch_assoc($query)) { 
    // Add some data 
    $objPHPExcel->setActiveSheetIndex(0) 
      ->setCellValue('A1', 'Codice Op') 
      ..... 
    ; 
} 

// Redirect output to a client’s web browser (Excel5) 
header('Content-Type: application/vnd.ms-excel'); 
header('Content-Disposition: attachment;filename="01simple.xls"'); 
header('Cache-Control: max-age=0'); 
// If you're serving to IE 9, then the following may be needed 
header('Cache-Control: max-age=1'); 

// If you're serving to IE over SSL, then the following may be needed 
header ('Expires: Mon, 26 Jul 1997 05:00:00 GMT'); // Date in the past 
header ('Last-Modified: '.gmdate('D, d M Y H:i:s').' GMT'); // always modified 
header ('Cache-Control: cache, must-revalidate'); // HTTP/1.1 
header ('Pragma: public'); // HTTP/1.0 

$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5'); 
$objWriter->save('php://output'); 
exit;

還要注意的是mysql擴展在PHP過時，你確實應該使用mysqli或帶有預處理語句/綁定變量的PDO來保護您的腳本免受SQL注入的影響

你能幫我通過對代碼進行必要的修改嗎？ –

現在已下載但空白xls文件:( –

也許你的SQL查詢沒有返回任何記錄 –
