PHP PDFLIB PHPMAILER创建，保存，发送

Question

我想创建PDF使用PDFLIB，将其保存到服务器，发送给收件人，并打开它毕竟！ 使用此代码，我可以创建它，将其保存到服务器，发送它，但不显示在浏览器的pdf应用程序中。 对此有何帮助？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。您在之前输出的文字标识为PDF的标题，会将其分解。我希望你会收到错误记录，说明这些调用的“头文件已经发送”到header()。注释掉echo "Message sent!";一行。
