PHP PDFLIB PHPMAILER 创建、保存、发送

Question

我想使用 PDFLIB 创建一个 PDF，将其保存到服务器，然后发送给收件人并打开它！ 使用此代码，我可以创建它，将其保存到服务器，发送但不在浏览器的 pdf 应用程序中显示。 有什么帮助吗？提前致谢。

<?php

    try {
     $p = new PDFlib();

     /* all strings are expected as utf8 */
     $p->set_option("stringformat=utf8");

     /*  open new PDF file; insert a file name to create the PDF on disk */
     if ($p->begin_document("test.pdf", "") == 0) {
     die("Error: " . $p->get_errmsg());
    }

    $p->set_info("Creator", "hello.php");
    $p->set_info("Author", "Rainer Schaaf");
    $p->set_info("Title", "Hello world (PHP)!");

    $p->begin_page_ext(595, 842, "");

    $font = $p->load_font("Helvetica-Bold", "unicode", "");
    if ($font == 0) {
    die("Error: " . $p->get_errmsg());
    }

    $p->setfont($font, 24.0);
    $p->set_text_pos(50, 700);
    $p->show("Hello world!");
    $p->continue_text("(says PHP)");
    $p->end_page_ext("");
    $p->end_document("");

基本的 HTTP 问题。您正在输出文本之前将其标识为 PDF 的标题，这将破坏它。我希望您从那些对header() 的调用中收到错误记录，称“标头已发送”。注释掉echo "Message sent!"; 行。
