PHPExcel打开输出的Excel文件时出错

Question

我希望我在正确的地方。我有这个PHP将数据从SQL导出到XLSX。

<?php 



$conexion=odbc_connect("syb_master","sa","server"); 

$sql = "Here's the query"; 

    $exec = odbc_exec($conexion,$sql); 

$resultado = odbc_result_all($exec); 
$registros = odbc_num_rows ($resultado); 
require_once '../Classes/PHPExcel.php'; 


if ($registros > 0) { 

    $objPHPExcel = new PHPExcel(); 

    //Informacion del excel 
    $objPHPExcel-> 
    getProperties() 
     ->setCreator("ingenieroweb.com.co") 
     ->setLastModifiedBy("ingenieroweb.com.co") 
     ->setTitle("Exportar excel desde mysql") 
     ->setSubject("Ejemplo 1") 
     ->setDescription("Documento generado con PHPExcel") 
     ->setKeywords("ingenieroweb.com.co con phpexcel") 
     ->setCategory("ciudades");  

    $i = 1;  
    while ($registro = odbc_fetch_object ($resultado)) { 

     $objPHPExcel->setActiveSheetIndex(0) 
      ->setCellValue('A'.$i, $registro->name); 

     $i++; 

    } 
    $objPHPExcel->getActiveSheet()->setTitle('Simple'); 
} 

header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet'); 
header('Content-Disposition: attachment;filename="ejemplo1.xlsx"'); 
header('Cache-Control: max-age=0'); 



$objWriter=PHPExcel_IOFactory::createWriter($objPHPExcel,'Excel2007'); 
$objWriter->save('php://output'); 
exit; 
odbc_close($conexion); 
?> 

它的工作原理导出到XLS的时候，但是当我出口到XLS，一切似乎除了一个事实，即在完成后，Excel不能打开该文件正确。它给出错误：“Excel无法打开文件，因为文件格式或文件扩展名无效。”

我认为这是因为查询有很多数据，但我不确定。我是phpexcel的新手。我希望你能帮助我。谢谢！

这是我的代码。这不太好，但我有没有这样的问题：

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

define('EOL',(PHP_SAPI == 'cli') ? PHP_EOL : '<br />'); 

/** Include PHPExcel */ 
require_once 'Classes/PHPExcel.php'; 


// Create new PHPExcel object 
//echo date('H:i:s') , " Create new PHPExcel object" , EOL; 
$objPHPExcel = new PHPExcel(); 

// Rename worksheet 
$objPHPExcel->getActiveSheet()->setTitle('Simple'); 
$objPHPExcel->getActiveSheet()->getColumnDimension('A')->setWidth(50);  
$objPHPExcel->getActiveSheet()->getColumnDimension('B')->setWidth(50);  
$objPHPExcel->getActiveSheet()->getColumnDimension('C')->setWidth(50);  
$objPHPExcel->getActiveSheet()->getColumnDimension('D')->setWidth(50); 

$objPHPExcel->getProperties()->setCreator("Ketov Alexandr") 
          ->setLastModifiedBy("Ketov Alexandr") 
          ->setTitle("PHPExcel Test Document") 
          ->setSubject("PHPExcel Test Document") 
          ->setDescription("Test document for PHPExcel, generated using PHP classes.") 
          ->setKeywords("office PHPExcel php") 
          ->setCategory("Test result file"); 

//$objPHPExcel->getActiveSheet()->getRowDimension(1)->setRowHeight(-1); 

$query = "SELECT * FROM `lang`"; 
$result = mysql_query($query) or die(mysql_error()); 


$objPHPExcel->setActiveSheetIndex(0) 
      ->setCellValue('A1', 'Ключ') 
      ->setCellValue('B1', 'На русском') 
      ->setCellValue('C1', 'На казахском') 
      ->setCellValue('D1', 'Портлет'); 

$styleArray = array(
    'font' => array(
     'bold' => true, 
     'color' => array('rgb' => '000000'), 
     'size' => 11, 
     'name' => 'Verdana' 
    )); 


$objPHPExcel->getActiveSheet()->getStyle('A1')->applyFromArray($styleArray)->getBorders()->getAllBorders()->setBorderStyle(PHPExcel_Style_Border::BORDER_THIN); 
$objPHPExcel->getActiveSheet()->getStyle('B1')->applyFromArray($styleArray)->getBorders()->getAllBorders()->setBorderStyle(PHPExcel_Style_Border::BORDER_THIN);

$objPHPExcel->getActiveSheet()->getStyle('D1')->applyFromArray($styleArray)->getBorders()->getAllBorders()->setBorderStyle(PHPExcel_Style_Border::BORDER_THIN); 

$n = 2; 
while ($row = mysql_fetch_object($result)) 
{ 
    $objPHPExcel->setActiveSheetIndex(0) 
      ->setCellValue('A'.$n, $row->id) 
      ->setCellValue('B'.$n, $row->ru) 
      ->setCellValue('C'.$n, $row->kz) 
      ->setCellValue('D'.$n, $row->module); 
    $objPHPExcel->getActiveSheet()->getStyle('A'.$n)->getBorders()->getAllBorders()->setBorderStyle(PHPExcel_Style_Border::BORDER_THIN); 
    $objPHPExcel->getActiveSheet()->getStyle('B'.$n)->getBorders()->getAllBorders()->setBorderStyle(PHPExcel_Style_Border::BORDER_THIN); 
    $objPHPExcel->getActiveSheet()->getStyle('C'.$n)->getBorders()->getAllBorders()->setBorderStyle(PHPExcel_Style_Border::BORDER_THIN); 
    $objPHPExcel->getActiveSheet()->getStyle('D'.$n)->getBorders()->getAllBorders()->setBorderStyle(PHPExcel_Style_Border::BORDER_THIN); 
    $n++; 
} 

// Set active sheet index to the first sheet, so Excel opens this as the first sheet 
$objPHPExcel->setActiveSheetIndex(0);
