php实现pdf文件的生成与下载
这个有点复杂的，我们一步一步来说明。
受先我们要下载pdf需要的文件，搜索‘php生成pdf’找到相关进行下载，这里不做介绍
//pdf下载
$name = $_SESSION['ex_uname'];
$name_pdf=$name.'.pdf';
$url = $_SERVER['DOCUMENT_ROOT']."/static/download/".$name;
if (false == file_exists($url.'/'.$name_pdf)) {
$name = $_SESSION['ex_uname'];
$url = $_SERVER['DOCUMENT_ROOT']."/static/download/".$name;
@mkdir ( $_SERVER['DOCUMENT_ROOT']."/static/download/".$name, 0777 );//新建文件夹
//echo dirname(dirname(__FILE__)).'/static/pdf/tdpdf/tcpdf_autoconfig.php';exit;
require_once($_SERVER['DOCUMENT_ROOT'].'/static/pdf/tcpdf/tcpdf.php');
