问题
I'm trying to get PDFlib support into PHP, but after finally figuring out how to install PDFlib, I get this error:
Fatal error: Uncaught exception 'PDFlibException' with message 'Function must not be called in 'object' scope'
Using the example code on 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);
?>
Does anyone have any ideas as to what could be causing this? I've tried googling around, but I've been unable to find any solutions.

What version of PDFLib are you using? If it's 6.0 or greater, try this code:
<?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);
?>
The functions pdf_open_file, pdf_begin_page, pdf_findfont, and pdf_close are all deprecated.

Or in "hard" and very not nice way - try moving your code somewhere to global scope.
回答3:
Please check the path where you are creating file.
pdf_open_file($pdf, "test.pdf");
Just ensure that the path is proper and error will gone away.
回答4:
Check for permission of your location you are passing. Mine is fixed with doing the same. It should have write permission.
chmod 0777 -R <PATH>
-R is recursive
path is certainly you stored in
pdf_open_file($pdf, "test.pdf");
in $pdf.
