我尝试了file_put_contents（），但是没有用。
$TestName = $row['TestName'];
$binary = $row['PdfReport'];
$binary = base64_decode($binary);
file_put_contents($TestName.'.pdf', $binary);
header('Content-type: application/pdf');
header('Content-Disposition: attachment; filename="'.$TestName.'.pdf"');
echo $TestName;
PDF文件已生成，但没有打开。当我打开pdf文件时，它显示了我的php文件代码。请帮忙。谢谢
