Question

我试图在点击按钮后生成excel文件。我把它作为形式：

<form method="post" action="ExcelStudio.php" target="_blank" style="float:right;">
    <input type="submit" name="export_excel_studio" class="button" value="Studio Report"></input>
</form>

因此，在提交表单后，我继续生成excel文件：

<?php
require_once ('PHPExcel/Classes/PHPExcel.php');
header('Content-Type: text/html; charset=utf-8');
include('inc/database_connection.php');
$conn = mysqli_connect(DATABASE_HOST, DATABASE_USER, DATABASE_PASSWORD, DATABASE_NAME); 

$output = '';
$conn->set_charset('utf8_unicode_ci');//if not by default
// Create new PHPExcel object
$objPHPExcel = new PHPExcel();
$F = $objPHPExcel->getActiveSheet();

if(isset($_POST["export_excel_studio"]))
{
    // 1.Get data
    $sql2 = '
                select
                  p2.proc_leader as username,
                       max(case when studio = "APEX" then "x" else "" end) as APEX,
                       max(case when studio = "BASECAMP" then "x" else "" end) as BASECAMP,
                       max(case when studio = "CANVAS" then "x" else "" end) as CANVAS,
                       max(case when studio = "HORIZON" then "x" else "" end) as HORIZON,

}

除了一件事，它工作得很好，我在桌子后面得到了奇怪的符号。所以我认为这意味着某处存在问题。这是我打开excel文件后得到的。什么可能是一个问题，我该如何解决这个问题？谢谢

通过更改文件来实现它：

header( "Content-Type: application/vnd.ms-excel" );
header( "Content-disposition: attachment; filename=StudioReport.xls" );
include('inc/database_connection.php');
$conn = mysqli_connect(DATABASE_HOST, DATABASE_USER, DATABASE_PASSWORD, DATABASE_NAME); 

$output = '';
$conn->set_charset('utf8_unicode_ci');//if not by default   
// print your data here. note the following:
// - cells/columns are separated by tabs ("\t")
// - rows are separated by newlines ("\n")

if(isset($_POST["export_excel_studio"]))
{
    // 1.Get data
    $sql2 = '
                select
