pdf_open

Description

bool pdf_open_file ( resource pdfdoc, string filename )

Create a new PDF file using the supplied file name. If filename is empty the PDF document will be generated in memory instead of on file. The result must be fetched by the client with the pdf_get_buffer() function. Parameter filename is optional before PHP 4.3.5 or with PDFlib less than 5. 如果成功则返回 TRUE，失败则返回 FALSE。

The following example shows how to create a pdf document in memory and how to output it correctly.

<?php $pdf = pdf_new(); pdf_open_file($pdf); pdf_begin_page($pdf, 595, 842); pdf_set_font($pdf, "Times-Roman", 30, "host"); pdf_set_value($pdf, "textrendering", 1); pdf_show_xy($pdf, "A PDF document created in memory!", 50, 750); pdf_end_page($pdf); pdf_close($pdf); $data = pdf_get_buffer($pdf); header("Content-type: application/pdf"); header("Content-disposition: inline; filename=test.pdf"); header("Content-length: " . strlen($data)); echo $data; ?>

"Fatal error: PDFlib error: [2100] PDF_begin_page: Function must not be called in 'object' scope"



I found a solution for this fault: 

when i got the fault, this was the script -> 



<?php



$pdf = pdf_new();



pdf_open_file($pdf, "C:\web\pdf\test45.pdf");

pdf_begin_page($pdf, 595, 842);

pdf_set_font($pdf, "Times-Roman", 30, "host");

pdf_set_value($pdf, "textrendering", 1);

pdf_show_xy($pdf, "A PDF document is created!", 50, 750);

pdf_end_page($pdf);

pdf_close($pdf);



?> 



but when i added some slashes to the path:



<?php



$pdf = pdf_new();



pdf_open_file($pdf, "C:\\web\\pdf\\test45.pdf");

pdf_begin_page($pdf, 595, 842);

pdf_set_font($pdf, "Times-Roman", 30, "host");

pdf_set_value($pdf, "textrendering", 1);

pdf_show_xy($pdf, "A PDF document is created!", 50, 750);

pdf_end_page($pdf);

pdf_close($pdf);



?> 



there wasn't no fault anymore and the pdf-file was succesfully created



I think you guys get the point ( add 2 slashes )

"Fatal error: PDFlib error: [2100] PDF_begin_page: Function must not be called in 'object' scope.."



If you get this error then you probably forgot to call pdf_open_file() or pdf_open_file() failed.

The example uses pdf_set_font, but that function is deprecated. Instead use pdf_setfont (without the underscore).

...

$fd = fopen("download/liste.pdf", "w");

$pdfdoc = pdf_open($fd);

pdf_begin_page($pdfdoc, 595, 842);

pdf_set_font($pdfdoc, "Helvetica", 20, "host", 1);

pdf_set_text_pos($pdfdoc, 50, 795);

pdf_show($pdfdoc, "Liste");

...

does not work under PHP5, use

...

$fd = fopen("download/liste.pdf", "w");

$pdfdoc = pdf_new();

pdf_open_file($pdfdoc, "download/liste.pdf");

pdf_begin_page($pdfdoc, 595.3, 841.8);

$font = pdf_findfont($pdfdoc, "Helvetica", "winansi", 0);

pdf_set_font($pdfdoc, $font, 20);

pdf_set_text_pos($pdfdoc, 50, 795);

pdf_show($pdfdoc, "Liste");

After some troubles I found filename must be absolute path  here in windows; relative path doesn't work in my box.

It is possible to append pdfs to each other, however it requires the commercial version of PDFlib with PDI support (http://www.pdflib.com) 



I've used it quite a bit and is well worth the price they are asking for.

When creating a pdf in memory, it appears that the code is executed twice. This does not seem to happen when creating a pdf as file. Not a problem when outputing a pdf, but does cause a problem if doing other writes in the same code:



// the write to the file is executed twice

$fp = fopen("testfile.htm", "a");

fwrite($fp, "testline/") ;

fclose($fp);

//--------------



$pdf = pdf_new();



if (!pdf_open_file($pdf, "")) {

    print error;

    exit;

};



pdf_begin_page($pdf, 8.5*72, 11*72);

pdf_set_font($pdf, "Helvetica-Bold", 24, "host");

pdf_set_text_pos($pdf, 50, 700);

pdf_show($pdf,"Hello,world!");

pdf_end_page($pdf);

pdf_close($pdf);



$buf = pdf_get_buffer($pdf);

$len = strlen($buf);



header("Content-type: application/pdf");

header("Content-Length: $len");

header("Content-Disposition: inline; filename=foo.pdf");

print $buf;

Appending to PDF files: plainly, you can't. PDF files have an internal structure that would get corrupted by just appending to the file. You'd need to parse the PDF, create a new PDF and mix your additions with the old PDF. Just creating a new one should be *much* easier.



Reading back the results: do a fopen() on the temporary file and use fgets() to read it. In your example where you just want to output the file, passthru should do the trick.

If you get "Fatal error: PDFlib error: function 'PDF_set_info' must not be called in 'object' scope in script.php on line xxx" when using pdf_open_file with a filename, make sure your webserver has write permissions to the directory your are trying to save your PDF file to.
