Remarque sur les fonctions obsolètes de la PDFlib

Depuis PHP 4.0.5, l'extension PHP pour la PDFlib est officiellement supportée par PDFlib GmbH. Cela signifie que toutes les fonctions décrites dans le manuel de référence de la PDFlib (PDFlib V3.0 ou supérieur) sont supportées par PHP 4 avec exactement la même signification et les mêmes paramètres. Cependant, avec la PDFlib V5.0.4 ou supérieure, tous les paramètres doivent être spécifiés. Pour des raisons de compatibilité, l'implémentation de la PDFlib supporte la plupart des fonctions obsolètes, mais elles doivent être remplacées par leur nouvelle version. PDFlib GmbH ne fournira aucun support pour les problèmes survenant lors de l'utilisation de ces fonctions obsolètes. La documentation de cette section indique les anciennes fonctions comme "obsolètes" et donne la fonction qui doit être utilisée à la place.

Folks, There is an excellent tutorial from Rasmus Lerdorf available at (It does not support I.E.)

http://talks.php.net/show/osconpdf/

Where PHP Mastermind Guru (Father) explained nicely about text, fonts, images and their attributes with working snippets.

Another tutorial can be found at

www.devshed.com/c/a/PHP/Building-PDF-Documents-with-PHP-5

Hence following is the various size of PDF Document.

Origin is at the lower left and the basic unit is the DTP pt.

1 pt = 1/72 inch = 0.35277777778 mm

Some common page sizes

Format          Width   Height
US-Letter      612      792
US-Legal       612      1008
US-Ledger     1224     792

For those of us that do not want to pay for a commercial license to use PDFlib I suggest TCPDF:

http://tcpdf.sf.net

TCPDF is an Open Source PHP class for generating PDF files on-the-fly without requiring external extensions. This class is already adopted by a large number of php projects such as phpMyAdmin, Drupal, Joomla, Xoops, TCExam, etc. 

Starting from 2.1 version TCPDF supports UTF-8 Unicode and bidirectional languages such as Arabic and Hebrew.

To get this to work on Windows do not use escapeshellcmd()

From online help:
Following characters are preceded by a backslash: #&;`|*?~<>^()[]{}$\, \x0A and \xFF. ' and " are escaped only if they are not paired. In Windows, all these characters plus % are replaced by a space instead.

So you are probably passing duff paths to pdf2text.exe

Removing escapeshellcmd worked for me. Just make darned sure you are in control of what is being passed through to your system call.

To extend alex's example earlier, you can use a couple of switches inside the pdf doc to give you the total number of pages, without using any ext. I would have added the whole code, however the site keeps on saying "line is too long... yadayada".

Open the doc using fopen("$file", "rb"); (for reading)

Test the first approx 1000b for the following regex
<?php
if(preg_match("/\/N\s+([0-9]+)/", $contents, $found)) {
    return $found[1];
}
?>

If that doesn't return anything, you have to read the rest of the file:

<?php

preg_match_all("/\/Type\s*\/Pages\s*\/Kids\s+
\[.*?\]\s*\/Count\s+([0-9]+)/");

?>

This may return more than one, so look through for the highest value, which is the total number of pages in your doc.

The other issue with DOMpdf is that it has some pretty painful flaws.

You have to supply full paths to everything (images, includes, javascript files, etc).  And boy, do i mean everything.

Even then, it is not 100% sound.  If you have complex sites, it cannot handle it.  It instead breaks the design and only provides you with about a million broken images.

Don't get me wrong, it's GREAT for use with lower-end more simple sites, but if you have a site that say, has a javascript navigation, flash, and a bunch of container divs, it's really not going to do the job.

The above library seems to be the best fit, as about the only way to get high-end sites to work is just to manually write it out yourself using the functions above.

Sorry to bust anyone's bubble.  Good luck.

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:

<?php
    $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.

http://www.digitaljunkies.ca/dompdf/index.php

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.

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

function pdf2string($sourcefile) {

    $fp = fopen($sourcefile, 'rb');
    $content = fread($fp, filesize($sourcefile));
    fclose($fp);

    $searchstart = 'stream';
    $searchend = 'endstream';
    $pdfText = '';
    $pos = 0;
    $pos2 = 0;
    $startpos = 0;

    while ($pos !== false && $pos2 !== false) {

        $pos = strpos($content, $searchstart, $startpos);
        $pos2 = strpos($content, $searchend, $startpos + 1);

        if ($pos !== false && $pos2 !== false){

            if ($content[$pos] == 0x0d && $content[$pos + 1] == 0x0a) {
                $pos += 2;
            } else if ($content[$pos] == 0x0a) {
                $pos++;
            }

            if ($content[$pos2 - 2] == 0x0d && $content[$pos2 - 1] == 0x0a) {
                $pos2 -= 2;
            } else if ($content[$pos2 - 1] == 0x0a) {
                $pos2--;
            }

            $textsection = substr(
                $content,
                $pos + strlen($searchstart) + 2,
                $pos2 - $pos - strlen($searchstart) - 1
            );
            $data = @gzuncompress($textsection);
            $pdfText .= pdfExtractText($data);
            $startpos = $pos2 + strlen($searchend) - 1;

        }
    }

    return preg_replace('/(\s)+/', ' ', $pdfText);

}

function pdfExtractText($psData){

    if (!is_string($psData)) {
        return '';
    }

    $text = '';

    // Handle brackets in the text stream that could be mistaken for
    // the end of a text field. I'm sure you can do this as part of the
    // regular expression, but my skills aren't good enough yet.
    $psData = str_replace('\)', '##ENDBRACKET##', $psData);
    $psData = str_replace('\]', '##ENDSBRACKET##', $psData);

        $psData,
        $matches

    for ($i = 0; $i < sizeof($matches[0]); $i++) {
        if ($matches[3][$i] != '') {
            // Run another match over the contents.

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 recently use mattb code below for the extraction of text from PDF files. I modify this code for only extract text fields.

Hope i can help some one

Here is the Function
