空白页，没有下载PHPExcel

Question

谁能帮助我使用PHPExcel？

我有这个代码...

<?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');

    /** Include PHPExcel */

exit;

当我尝试读取数据库数据并将其下载为excel格式时，出现空白页且没有下载。

我对此没有任何错误。 我不知道该怎么办

Answer 1

显而易见的问题（只是在这段代码中徘徊）

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

仍将继续执行其余代码

您将包括PHPExcel，创建一个新的PHPExcel对象，并在$userRow1 = mysql_fetch_assoc($query))循环$userRow1 = mysql_fetch_assoc($query))迭代的每一行的响应发送到浏览器。...我假设您确实希望将每一行写入同一文件

编辑

为了使答案简单而不是一堵墙，您的结构应类似于：

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;

还要注意，PHP中不建议使用mysql扩展，您实际上应该将mysqli或PDO与已准备好的语句/绑定变量一起使用，以保护脚本免受SQL注入
