PDFLib来给未捕获的异常错误(PDFLib giving an uncaught excepti

我试图获得支持的PDFlib到PHP，但后，终于搞清楚如何安装PDFlib，所以我得到这个错误：

Fatal error: Uncaught exception 'PDFlibException' with message 'Function must not be called in 'object' scope'

使用的示例代码php.net ：

<?php
// create handle for new PDF document
$pdf = pdf_new();
// open a file
pdf_open_file($pdf, "test.pdf");
// start a new page (A4)
pdf_begin_page($pdf, 595, 842);
// get and use a font object
$arial = pdf_findfont($pdf, "Arial", "host", 1); pdf_setfont($pdf, $arial, 10);
// print text
pdf_show_xy($pdf, "There are more things in heaven and earth, Horatio,",50, 750);
pdf_show_xy($pdf, "than are dreamt of in your philosophy", 50,730);
// end page
pdf_end_page($pdf);
// close and save file
pdf_close($pdf);
?>

没有人有任何想法，这可能是导致此？我试着用搜索引擎周围，但我一直无法找到任何解决方案。

Answer 1:

您正在使用什么版本的PDFlib？如果是6.0或更高，试试这个代码：

<?php
// create handle for new PDF document
$pdf = PDF_new();
// open a file
PDF_begin_document($pdf, "test.pdf");
// start a new page (A4)
PDF_begin_page_ext($pdf, 595, 842);
// get and use a font object
$arial = PDF_load_font($pdf, "Arial", "host", 1); pdf_setfont($pdf, $arial, 10);
// print text
PDF_show_xy($pdf, "There are more things in heaven and earth, Horatio,",50, 750);
PDF_show_xy($pdf, "than are dreamt of in your philosophy", 50,730);
// end page
PDF_end_page_exit($pdf);
// close and save file
PDF_end_document($pdf);
?>

功能pdf_open_file, pdf_begin_page, pdf_findfont, and pdf_close都已过时。
