PHP PDFlib unicode

Question

是否可以在UTF-8中呈现pdf。波斯字符还是阿拉伯字符？我不想用tcpdf。它在通过php脚本生成pdf时存在性能问题。我会尝试最新版本的php 5.4和pdflib 8.0.4p2，但我看不到有效的波斯语单词。

<?php 

try {
    $p = new PDFlib();

    /*  open new PDF file; insert a file name to create the PDF on disk */
    if ($p->begin_document("", "") == 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("Courier", "unicode", "");

    $p->setfont($font, 24.0);
    $p->set_text_pos(50, 700);
    $p->show("Hello world!");
    $p->continue_text($p->utf8_to_utf16("(says PHP) سلام جهان", 'utf16'));
    $p->end_page_ext("");

    $p->end_document("");

    $buf = $p->get_buffer();
    $len = strlen($buf);

    header("Content-type: application/pdf");
    header("Content-Length: $len");
    header("Content-Disposition: inline; filename=hello.pdf");
    print $buf;
}
catch (PDFlibException $e) {
    die("PDFlib exception occurred in hello sample:\n" .
    "[" . $e->get_errnum() . "] " . $e->get_apiname() . ": " .
    $e->get_errmsg() . "\n");
}
catch (Exception $e) {
    die($e);
}
$p = 0;

主要问题是Courier字体没有您要打印的阿拉伯文本的字形。如果你使用像Arial Unicode这样的字体，你会看到预期的结果。

另一个技巧是，使用$p->set_parameter("textformat", "utf8");，然后就可以像在$p->continue_text("(says PHP) سلام جهان x");中那样直接使用utf8
