Question

我试图使用mpdf生成pdf文件。它包含超过50000页。问题是浏览器可以处理并显示pdf文件，当它有2000页时但是当我试图生成更多时，浏览器没有响应，最后，它显示max_execution_time虽然我将max_execution_time 30增加到300表单php.ini文件，但所有错误。

这是我的mpdf代码......

<?php
// header('Content-type: application/force-download');
// header("Content-type:application/pdf");
ini_set("memory_limit","128M");
ob_start();


include("fpdf/mpdf/mpdf.php");
// $mpdf=new mPDF('mm','array(140,215)',14,'nikosh'); 
$mpdf = new mPDF('0',array(280,216),12,'nikosh',3,3,'L'); 
$mpdf->SetTopMargin(0);
$mpdf->SetRightMargin(0);
$mpdf->useSubstitutions = false;
$mpdf->simpleTables = true;
$stylesheet = file_get_contents('style.css');

Answer 1

您有两种选择：

在没有`max_execution_time`

的情况下在后台生成PDF

在处理这种规模的事情时，无论如何都应该这样做。使用cli脚本生成PDF，cli php.ini通常没有设置max_execution_time。将您的PDF保存在磁盘上进一步利用（发送，共享，链接下载）。

浏览器并不意味着显示如此大量的数据，使用适当的桌面PDF查看器可以获得更好的性能。

生成此大小的PDF时，您很可能遇到内存限制问题，为此，还有第二个选项：

以较小的块在后台生成PDF文件，并将它们与外部程序连接

将HTML拆分为最多100页的块，使用cli生成单独的文档（每个文档都运行一个新的干净脚本），并将生成的PDF文档与外部程序连接起来，例如。 GhostScript的：

gs -dBATCH -dNOPAUSE -q -sDEVICE=pdfwrite -sOutputFile=out.pdf in1.pdf in2.pdf

或pdftk：

pdftk in1.pdf in2.pdf cat output out.pdf
