PHPExcel:在客户端下载Excel文件

Question

问题已解决:对于可能存在此问题的其他用户 - 请注意PHP文件的编码.如果您使用PHPExcel,它必须是ANSII编码而不是UTF8,否则将彻底下载EXCEL.添加的标题(答案1)在我更改了文件本身的编码后解决了问题.

我正在使用PHPExcel从MYSQL DB中的表创建一个EXCEL,因此用户可以将其下载到他的计算机上.

下面的代码创建了一个正确的Excel文件,但问题是它被下载到我的服务器.我在PHPExcel手册中读到我需要添加标题:

header('Content-Type: application/vnd.ms-excel');
header('Content-Disposition: attachment;filename="'.$name.'.xls"');
header('Cache-Control: max-age=0');
header('Cache-Control: max-age=1');
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');

但是,如果我这样做,下载的文件是:1.内部有一些jibrish 2.说Excel需要修复它,因为文件不好.问题是这个文件保存为UTF8,如果我把它编码为ANSI然后它正常工作,但当然这是一个手动更改,我需要一个正常工作excel到达用户.

什么是虫子？

我的代码有效(但将文件下载到服务器):

<?php
include 'connection.php';
include 'checkUser.php';

//Getting all the needed information from the DB
$task_id=$_GET['id'];
$query2 = "SELECT * FROM projects WHERE ProjectID=$task_id";
$data2 = mysqli_query($con, $query2);
$row = mysqli_fetch_array($data2);
$project_type = $row['ProjectType'];
$project_name = $row['ProjectName'];

switch ($project_type){
                    case 2: $NumberOfRows=22;  $project = "slivedetails"; break;
                    case 3: $NumberOfRows=30;  $project = "plivedetails"; break;
                    default: $NumberOfRows=0; $project = "none";
                    }
//column names
if ($project="slivedetails"){
    $ColumnNames = mysqli_query($con,"SHOW COLUMNS FROM slivedetails") or die("mysql error"); 
    }
else if ($project="plivedetails"){
    $ColumnNames = mysqli_query($con, "SHOW COLUMNS FROM plivedetails") or die("mysql error"); 
    }

$query = "SELECT * FROM $project WHERE TaskID=$task_id";
$data = mysqli_query($con, $query);
$num_rows = mysqli_num_rows($data); 


/** Include PHPExcel */
require_once 'PHPExcel_1.7.9_doc/Classes/PHPExcel.php';
require_once 'PHPExcel_1.7.9_doc/Classes/PHPExcel/IOFactory.php';


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

// writer already created the first sheet for us, let's get it
$objSheet = $objPHPExcel->getActiveSheet();
// rename the sheet
$objSheet->setTitle('Task Results');

// let's bold and size the header font and write the header
// as you can see, we can specify a range of cells, like here: cells from A1 to A4
$objSheet->getStyle('A1:AD1')->getFont()->setBold(true)->setSize(12);

$char = 65;
// write header]
for ($i=1;$i<=$NumberOfRows;$i++){
    $col_name = mysqli_fetch_array($ColumnNames);
    $objSheet->getCell(chr($char).'1')->setValue($col_name['Field']);
    $char++;
}

// Now we need to get the data from the DB. While we have a row in the result:
$rowIterator=2; //our row number. We begin from 2 because the first one is the title.

while ($RowInfo = mysqli_fetch_array($data)){
//We will fill the information based on the amount of columns:
$char = 65; //we set the first char as column A
for ($i=0;$i<$NumberOfRows;$i++){
    $objSheet->getCell(chr($char).$rowIterator)->setValue($RowInfo[$i]);
    $char++;
}
$rowIterator++;
}

// autosize the columns
$char = 65;
for ($i=1;$i<=$NumberOfRows;$i++){
    $objSheet->getColumnDimension(chr($char))->setAutoSize(true);
    $char++;
}

// create the writer
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, "Excel2007");
$objWriter->save('results.xlsx');


?>

Answer 1

删除以下内容:

require_once 'PHPExcel_1.7.9_doc/Classes/PHPExcel/IOFactory.php';

您将对象声明了两次.删除其中一个:

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

在创建Writer之前插入以下标题:

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

而不是以下(实际上将文件保存在服务器中):

$objWriter->save('results.xlsx');

插入以下内容(将创建可下载文件):

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

这应该解决胡言乱语的问题.如果仍然获得此类文本,请在最后一行($objWriter->save("php://output");)之前插入以下代码:

ob_clean();

这对我有用.希望能帮助到你.
