LXXXIII. PDF functions
소개
The PDF functions in PHP can create PDF files using the PDFlib library created by Thomas Merz.
The documentation in this section is only meant to be an overview of the available functions in the PDFlib library and should not be considered an exhaustive reference. Please consult the documentation included in the source distribution of PDFlib for the full and detailed explanation of each function here. It provides a very good overview of what PDFlib is capable of doing and contains the most up-to-date documentation of all functions.
All of the functions in PDFlib and the PHP module have identical function names and parameters. You will need to understand some of the basic concepts of PDF and PostScript to efficiently use this extension. All lengths and coordinates are measured in PostScript points. There are generally 72 PostScript points to an inch, but this depends on the output resolution. Please see the PDFlib documentation included with the source distribution of PDFlib for a more thorough explanation of the coordinate system used.
Please note that most of the PDF functions require a pdfdoc as its first parameter. Please see the examples below for more information.
참고: If you're interested in alternative free PDF generators that do not utilize external PDF libraries, see this related FAQ.
요구 사항
PDFlib is available for download at http://www.pdflib.com/products/pdflib/index.html, but requires that you purchase a license for commercial use. The JPEG and TIFF libraries are required to compile this extension.
Issues with older versions of PDFlib
Any version of PHP 4 after March 9, 2000 does not support versions of PDFlib older than 3.0.
PDFlib 3.0 or greater is supported by PHP 3.0.19 and later.
설치
To get these functions to work, you have to compile PHP with --with-pdflib[=DIR]. DIR is the PDFlib base install directory, defaults to /usr/local. In addition you can specify the jpeg, tiff, and pnglibrary for PDFlib to use, which is optional for PDFlib 4.x. To do so add to your configure line the options --with-jpeg-dir[=DIR] --with-png-dir[=DIR] --with-tiff-dir[=DIR].
When using version 3.x of PDFlib, you should configure PDFlib with the option --enable-shared-pdflib.

Confusion with old PDFlib versions
Starting with PHP 4.0.5, the PHP extension for PDFlib is officially supported by PDFlib GmbH. This means that all the functions described in the PDFlib manual (V3.00 or greater) are supported by PHP 4 with exactly the same meaning and the same parameters. Only the return values may differ from the PDFlib manual, because the PHP convention of returning FALSE was adopted. For compatibility reasons, this binding for PDFlib still supports the old functions, but they should be replaced by their new versions. PDFlib GmbH will not support any problems arising from the use of these deprecated functions.

예제
Most of the functions are fairly easy to use. The most difficult part is probably creating your first PDF document. The following example should help to get you started. It creates test.pdf with one page. The page contains the text "Times Roman outlined" in an outlined, 30pt font. The text is also underlined.
The PDFlib distribution contains a more complex example which creates a page with an analog clock. Here we use the in-memory creation feature of PDFlib to alleviate the need to use temporary files. The example was converted to PHP from the PDFlib example. (The same example is available in the CLibPDF documentation.)

I seriously tried to get PDF parsing to work to use it in the indexing for fulltext search for a document management. But none of the pdf2text functions below worked for my test cases (among them an openoffice generated pdf file and a file generated by fpdf).
But I found a REALLY WORKING SOLUTION! On linux systems, install the XPDF package. It comes with a tool called pdftotext. Use php code similar to the following to get the text content of your pdf files:
<?
$file = "test.pdf";
$outpath = preg_replace("/\.pdf$/", "", $file).".txt";
system("pdftotext ".escapeshellcmd($file), $ret);
if ($ret == 0)
{
$value = file_get_contents($outpath);
unlink($outpath);
print $value;
}
if ($ret == 127)
print "Could not find pdftotext tool.";
if ($ret == 1)
print "Could not find pdf file.";
?>
The solution works on all test cases and is much more powerful than any of the previous pure php functions posted here, although only available on linux.

PHP5 class that converts HTML to PDF. From the website:
"At its heart, dompdf is (mostly) CSS2.1 compliant HTML layout and rendering engine written in PHP. It is a style-driven renderer: it will download and read external stylesheets, inline style tags, and the style attributes of individual HTML elements. It also supports most presentational HTML attributes."

Easiest way to get the text of a pdf is to install xpdf (on redhat yum -y install xpdf)
then run xpdftotext your.pdf - which will then generate your.txt.

I am trying to extract the text from PDF files and use it to feed a search engine (Intranet tool). I tried several functions "PDF2TXT" posted below, but not they do not produce the expected result. At least, all words need to be separated by spaces (then used as keywords), and the "junk" codes removed (for example: binary data, pictures...). I start modifying the interesting function posted by Swen, and here is the my current version that starts to work quite well (with PDF version 1.2). Sorry for having a quite different style of programming. Luc

Here is a function to test whether a file is a PDF without using any external library.
<?php
define('PDF_MAGIC', "\\x25\\x50\\x44\\x46\\x2D");
function is_pdf($filename) {
return (file_get_contents($filename, false, null, 0, strlen(PDF_MAGIC)) === PDF_MAGIC) ? true : false;
}
?>
It's not checking if the whole file is valid, just if the correct header is present at the beginning of the file.

domPDF is also a great PDF creation interface. it basically converts your code to CSS and then builds the PDF from that with the absolute positions, and what not...

I was having trouble with streaming inline PDf's using PHP 5.0.2, Apache 2.0.54.
This is my code:
<?
header("Pragma: public");
header("Expires: Mon, 26 Jul 1997 05:00:00 GMT");
header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT");
header("Cache-Control: must-revalidate");
header("Content-type: application/pdf");
header("Content-Length: ".filesize($file));
header("Content-disposition: inline; filename=$file");
header("Accept-Ranges: ".filesize($file));
readfile($file);
exit();
?>
It would work fine in Mozilla Firefox (1.0.7) but with IE (6.0.2800.1106) it would not bring up the Adobe Reader plugin and instead ask me to save it or open it as a PHP file.
Oddly enough, I turned off ZLib.compression and it started working. I guess the compression is confusing IE. I tried leaving out the content-length header thinking maybe it was unmatched filesize (uncompressed number vs actual received compressed size), but then without it it screws up Firefox too.
What I ended up doing was disabling Zlib compression for the PDF output pages using ini_set:
<?
ini_set('zlib.output_compression','Off');
?>
Maybe this will help someone. Will post over in the PDF section as well.

I was searching for a lowcost/opensource option for combining static html files [as templates] and dynamic output from perl or php routines etc. And the sooner or later I found out that this was the most stable, 'speedest' and customizeable way to produce usable pdf 's with nice formatting :
1] create html page output [perl-> html output, direct html output from any app or php echo's etc. [sort these html files locally]
2] parse all html [inluding webimages links, tables font formatting etc] to [E]PS files with the perl app : html2ps [as mentioned beneath]
http://user.it.uu.se/~jan/html2ps.html [sort all ps files by future pdf page positions]
3] use the free ps2pdf/ps2pdfwr linux application
http://www.ps2pdf.com/convert/index.htm [uses gostscript, ghostview libs and so on etc]
Has great formatting options like headers, footers, numbering etc
[sort pdf files]
4] convert all pdf files to 1 pdf file with : pdftk [pdftoolkit], deliveres optional compressions/encryption, background stamps etc
One should ask why using different scripts :
- combination perl/php is great : perl is speedier at some issues like conversion to ps files in my experience
- ps to pdf is quickier then direct php to pdf [in my exp.!]
- I have total control over every files whenever i change html files as a template I use only editors or other app. for it [online or offline].
p.s. I had to make a opensource solution for creating simpel report analyses that's based on things like :
- first page [name / title / #/ date]
- some static info [like introduction, copyrights etc]
- some dynamic info [outputted from php->dbase queries] combined
with html tags/images etc.
And this all mixed [so seperated in files for transparancy]. Also the 3 way manner : data-> html, html->ps, ps->pdf, is easier and quickier to program or adjust in every step.
Correct me if i'm wrong [mail me to]

After one hole day understanding how pdflib works i got the conclusion that its enough hard to draw just with words to furthermore for drawing a line maybe you will need something like four lines of code, so i did my own functions to do the life easier and the code more understable to modify and draw. I also made a function that will draw a rect with the corners round and the posibility even to fill it ;)
You can get it from http://www.deulos.com/pdf_php.php
feel free to make suggestions or whatever u like ;o)

Yet another addition to the PDF text extraction code last posted by jorromer. The code only seemed to work for PDF 1.2 (Acrobat 3.x) or below. This pdfExtractText function uses regular expressions to cover cases I have found in PDF 1.3 and 1.4 documents. The code also handles closing brackets in the text stream, which were ignored by the previous version. My regular expression skills are somewhat lacking, so improvements may possible by a more skilled programmer. I'm sure there are still cases that this function will not handle, but I haven't come across any yet...
<?php

If you want to display the number of pages (for example: page 1 of 3) then the following code could be helpful:
<?php
...
$pdf->begin_page_ext(842,595 , "");
.. add text,images,...
$pdf->suspend_page("");
$pdf->begin_page_ext(842,595 , "");
.. add text,images,...
$pdf->suspend_page("");
... create all pages
$pdf->resume_page("pagenumber 1");
... add number of pages to page 1
$pdf->end_page_ext("");
$pdf->resume_page("pagenumber 2");
... add number of pages to page 2
$pdf->end_page_ext("");
...

I found this info about pdflib scope on a Chinese (I think) site and translated it. I was trying to do pdf_setfont and kept getting the wrong scope error. Turns out it has to be in the Page scope. So pdf_setfont will only work when called between pdf_begin_page and pdf_end_page.

How to get how many pages in a PDF? I read PDF spec. V1.6 and find this:
PDF set a "Page Tree Node" to define the ordering of pages in the document. The tree structure allows PDF applications, using little memory to quickly open a document containing thousands of pages.
If a PDF have 63 pages, the page tree node will like this...
2 0 obj
<< /Type /Pages
/Kidsn [ 4 0 R
10 0 R
]
/Count 63 <---- YES, got it
>>
endobj
[P.S] a PDF may not only a pages tree node, The right answer is in "root page tree node", if /Count XX with /Parent XXX node, it not "root page tree node"
SO, You must find the node with /Count XX and Without /Parent terms, and you'll get total pages of PDF
%PDF-1.0 ~ %PDF-1.5 all works

I recently tested Donatas' code below for the extraction of text from PDF files. After running into a few problems where PDF files were not being read at all, I've modified it somewhat. It still isn't perfect, but should work great for searching. Thanks Donatas.

I've been looking for a way to extract plain text from PDF documents (needed to search for text inside 'em). Not being able to find one I wrote the needed functions myself. here you go folks.
<?php
function pdf2string ($sourceFile)

$searchTagStartLenght = strlen ($searchTagStart);
while ((($objStart = strpos ($content, $searchTagStart, $objStart)) && ($objEnd = strpos ($content, 'endstream', $objStart+1))))
{
$data = substr ($content, $objStart + $searchTagStartLenght + 2, $objEnd - ($objStart + $searchTagStartLenght) - 2);
$data = @gzuncompress ($data);
if ($data !== FALSE && strpos ($data, 'BT') !== FALSE && strpos ($data, 'ET') !== FALSE)
{
$textArray [] = ExtractText ($data);
}
$objStart = $objStart < $objEnd ? $objEnd : $objStart + 1;
}
return $textArray;
}
function ExtractText ($postScriptData)

Those looking for a free replacement of pdflib may consider
pslib at http://pslib.sourceforge.net which produces PostScript but it can be easily turned into PDF by Acrobat Distiller or ghostscript. The API is very similar and even hypertext functions are supported. There
is also a php extension for pslib in PECL, called ps.

About creating a PDF document based on the content of another document(let's say a text file):
I have tried to send to the PDF-creator page from a link from the sender page the file name of the file I want to read the content from and generate the PDF document containing this content. The idea is is that when I tried to reffer the pdf-creator page via the link your_root/create_pdf.php?filename=$your_file_name, the pdf-creator page does not behave well when before creating the pdf document I have a line like $filename = $_GET["filename"].
I solved this using on the sender page instead of the link a form with a button, so the form has as action "create_pdf.php", as method "post" and a hidden field containing the "filename" value. And it works like this if, on the pdf-creator page I have a line like $filename = $_POST["filename"].
I would like to understand why this way it works and the other way does not.
I hope this helps. Here are the pieces of code I used.
Sender page:
print("<form name='to_pdf' action='see_pdf_file.php' method='post'>");
print("<br/><input type='submit' value='PDF'><input type='hidden' name='filename' value='$filename'></form>");
PDF-creator page:
<?
$filename = $_POST["filename"];
$file_handle = fopen($filename, "r");
$file_content = file_get_contents($filename);
fclose($file_handle);
//
$file_content = wordwrap($file_content,72,"|");
$a_row = explode("|",$file_content);
$i = 0;
//
$pdf = pdf_new();
pdf_open_file($pdf, "");
pdf_begin_page($pdf, 595, 842);
pdf_set_font($pdf, "Times-Roman", 16, "host");
pdf_add_outline($pdf, "Page 1");
pdf_set_value($pdf, "textrendering", 1);
pdf_show_xy($pdf, 'The content of the file:',50,700);
while ($a_row[$i] != "")
{
pdf_continue_text($pdf,$a_row[$i]);
$i++;
}
pdf_end_page($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;
?>

It seems to be a working bundle if you do some magic with ./configure:

If you want to use bundled GD-library then:
1) install following packages: libjpeg, libjpeg-devel, libpng, libpng-devel, freetype, freetype-devel, libtiff, libtiff-devel, zlib, zlib-devel
2) ln -s /usr/lib/libjpeg.so.62 /usr/lib/libjpeg.so
ln -s /usr/lib/libpng.so.62 /usr/lib/libpng.so
It seems to be a working combination, because it is NOT give you:
1) error message in Apache's error_log:
Module compiled with module API=20020429, debug=0, thread-safety=0
PHP compiled with module API=20020429, debug=0, thread-safety=1
2) error message in Apache's error_log:
[notice] child pid 12345 exit signal Segmentation fault (11)
3) MS Internet Explorer can show PDF-output from your PHP-script via Acrobat plug-in and does not crush. No confusing messages about opening "Adobe Acrobat Control for ActiveX".
Hope it will save you some time.
Good luck,
Boris
