My recipie:

1) untar pdflib-2.01.tar.gz
$./configure
$ make
$ make install

2) set a symlink 
$ ln -s /usr/local/lib/libpdf2.01.so /usr/local/lib/libpdf.so
You need to do this 'cause the PHP configure checks for pdflib with a
little C-program, compiling it and linking with library named libpdf (!)

2)
$ldconfig
this updates the info about dynamic library on your system (think about
the magic phrase  "Reboot  Windows "  )   ;-) 

3) go to cvs.php.net and checkout the source tree. 
You can find How-To on 

4) configure your php: 
$make 

Stop your Apache server with apachectl stop (don't forget it!!!!!)

$make install

$apachectl start
 and 
 .......... have happy time hacking with pdflib/php ! ;-> 

Luk.

The php mailinglist reported a problem with the
installation of pdflib 2.01. The file pdf.h which is to be copied e.g.
into /usr/local/include will end up as /usr/local/include if the directory
/usr/local/include does not exist already. This is because configure of
php to fail, since it can't find pdf.h

When pdflib2.01 is installed on a HPUX-10.20 system (perhaps others as
well?), the libs end with .sl not .so which means that you should use
"ln -s /usr/local/lib/libpdf2.01.sl /usr/local/lib/libpdf.sl"
instead!

You need the to get the latest pdf.c file from the CVS tree:
php4/ext/pdf/pdf.c


And make sure that you have patched pdflib 3.01, or you will have problem
writing pdf to file(httpd core dumps). 

After a couple of hours of trial and error, I've finally gotten PHP
4.0.1pl2, Apache 1.3.12, and PDF 3.01 to all work together.� Here are the
steps I followed.

Downloaded the above from the following sites:
PDFlib: www.pdflib.com
Apache: www.apache.org
PHP: www.php.net

I also downloaded the following:
PDFlib patch: 
Latest PHP pdf.c: 

After untarring the archives I did the following:
In PDF directory:
Applied PDF patch.
./configure --enable-cxx --with-tiffauxlib=-ljpeg --with-tifflib=/usr/lib
--with-zlib=/usr/lib --with-pnglib=/usr/lib --enable-shared
--enable-static --enable-shared-pdflib
make
make install

In Apache source directory:
./configure --prefix=/www/apache --with-perl=/usr/bin/perl
--enable-module=so --enable-module=rewrite
make
make install

In PHP direcotry
Copied over new pdf.c file.
./configure --with-mysql --with-apxs=/www/apache/bin/apxs
--enable-track-vars --with-zlib-dir --with-jpeg-dir=/usr/lib
--with-png-dir=/usr/lib --with-tiff-dir=/usr/lib --with-pdflib
make
make install

From there I configured httpd.conf as outlined in the PHP docs.� Hope this
helps.

Here are a couple of other notes I made when compiling in PDF 3.x support.

The PDF patch does not work, or at least I was unable to get it to work
using 'patch'.  You have to manually make changes to the pdf file.  Simply
look at the patch file to see what line to delete and add.  Lines with a
plus in front of them should be added while lines with a minus should be
deleted.

After compiling the PDF library, make sure '/usr/local/lib' appears in
/etc/ld.so.conf.  Also, it's probably a good idea to run 'ldconfig' once
the PDF library has been compiled.

Hope this helps.

Just FYI, I just find pdflib-3.0.1 and pdflib-3.0.2 does't work with
php-4.0.2 in my certain condition. Fortunately pdflib-3.0 does fine.

I'm runing Solaris 7 on a Sun Sparc, apache-1.3.12. DSO php-4.0.1pl2 or
php-4.0.2 works well without pdflib support. But when I install
pdflib-3.0.2, there's no DSO library made, which will cause php
configuration failed, in /usr/local/lib, nor does pdflib-3.0.1, no matter
how do I adjust the configure line parameters.

I have to back to pdflib-3.0, it works like a magic.

For PdfLib.dll v2.01 look 

My process to get this all working:

I use debian, so I used dselect to make sure that I had libtiff and
libjpeg.

Compile pdflib 3.02 "./configure --enabled-shared-pdflib --enable-cxx
--enable-static --enable-shared --with-tifflib=/usr/lib
--with-tiffauxlib=-ljpeg"

"make" then "make test" and "make install"

Edit /etc/ld.so.conf and include the line "/usr/local/lib"

"ln -s /usr/lib/libtiff.so.3.5.4 /usr/lib/libtiff.so"
"ln -s /usr/lib/libjpeg.so.62.0.0 /usr/lib/libjpeg.so"

"ldconfig"

Recompile PHP with "--with-pdflib"

If that doesn't work, make sure to check the last few lines of config.log
("tail -n 25 config.log") and look for errors.  Worked finally
for me with PHP 4.0.2.

There seems to be a [known] bug in
pdflib-3.0.1 where file descriptors
are overwritten, resulting in an
apache segfault when accessing pdf
functions. The bug is documented in
the changelog of pdflib-3.0.2,
which cures this problem. (Thanks to
Jani for catching this.)

[Editor's note: See the section "Security" in the manual for more
information on this and other security matters]

The script getpdf.php should only be used to learn the concept of passing
a file through a script and not actually used to perform this task.  In
its current state, there is a large security flaw which enables many files
(including all your php source) to be viewed by anyone.

For example 
shows the servers machines password file.

PHPLIB (3.0.2)

after compiling and installing pdflib3.0.2, it defaults to /usr/local/lib
and creates symlinks that the ./configure of PHP doesnot want to
recognize...

Simply run :
rm /usr/local/lib/libpdf.so.1
rm /usr/local/lib/libpdf.so
mv /usr/local/lib/libpdf.so.1.0.0 /usr/local/lib/libpdf.so.1

and everything will go right : -)

Having trouble getting MS IE to display your PDFs?

As [email protected] kindly wrote in the ClidPDF man page:

"I found out MSIE _REQUIRES_ a correctly set Content-Length header to
be sent beside Content-Type to correctly display PDFs"

After digging around in pdf.c I found two very useful undocumented PDF
functions.

pdf_add_pdflink(int pdfdoc, double llx, double lly, double urx, double
ury, string filename, int page, string dest)
Adds link to pdf document

void pdf_add_weblink(int pdfdoc, double llx, double lly, double urx,
double ury, string url)
Adds link to web resource

enjoy them.
kill-9 
www.kill-9.dk

Here is a short example to display PDF files without needing a
'redirection'.
Works also with IE thanks to the previous note.
Avoid spaces/newlines/whatever before and after the php script if you want
the file to be correctly handled as PDF.

Mathieu BOIS

pdftest.php :
<?php
$filename="/tmp/test.pdf";
$fp=fopen($filename,"w");
//CREATE YOUR PDF FILE HERE
fclose($fp);

$fp2=fopen($filename,"r");
header("Content-Length: ".filesize($filename)); // for IE to
work
header("Content-type: application/pdf");
fpassthru($fp2);
fclose($fp2);
?>

To get around the IE problem with content-length, you can use the output
buffering feature with PHP 4:

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

// turn output buffering on
ob_start();
$pdf = PDF_open();

// create your pdf here.

PDF_close($pdf);

// get the length of the document
$length = ob_get_length();

// output content-length header
header("Content-Length: $length");

// send pdf to the browser, flushing and turning off output buffering
ob_end_flush();
?>

This works for me in NS 4.7 and IE 5

just something from :
Quite Important!!!

Just to have it in the archive I am responding to myself.

I managed to get it to compile. The problem lies with the PDFlib and the
options you compile it with. I was seeing some errors in reference to
the png functions inside the PDFlib being undefined. I decided to
recompile without PNG support. (--with-pnglib=no). Even though my system
has PNGlib in /usr/local/lib. I tried it both ways and disabling the PNG
support seemed to be the way to go.

After recompiling, PHP is no longer stopped on pdf_show_boxed.

HTH somebody...

Ok, with the 3.03 version of pdflib, there's a bug in the library that
throw an error when you try to create the Pdf direct in memory using:

pdf_open();

You can fix this with the patch published in the pdflib page at:



After aplying the patch and recompiled the pdflib, you don't need to
recompile the php, just restart the webserver and you are ready to go, at
least it work for me =)
I use Linux, Apache and PHP as DSO.

Greettings and excuse my english, but it's not my mother language and is a
little late now ;-)
Ernesto Domato.

You're trying to configure php with support for pdflib. You get the
following error: 

checking whether to include Pdflib 3.x support... yes 
checking for PDF_show_boxed in -lpdf... no 
configure: error: pdflib extension requires at least pdflib 3.x.

You may also need libtiff and libjpeg. If so, what you need is to install

libjpeg-devel-6b-10.rpm

I don't know what source tarball has those development libraries or if
it's some make option I'm not aware of in the latest jpegsrc.v6b.tar.gz

When I installed that rpm both php and apache configured and compiled
perfectly...

I added the manually patched the file, configured with ./configure
--enable-shared-pdflib and nothing else, and used this modification of the
php page shown above:

<?
header( "Content-type: application/x-pdf" );
$f = fopen("/tmp/test", "w");
$pdf = PDF_open($f);
//$pdf = PDF_new();
PDF_set_info_author($pdf, "Luca Perugini");
PDF_set_info_title($pdf, "Brochure for FlyStore");
PDF_set_info_creator($pdf, "See Author");
PDF_set_info_subject($pdf, "FlyStore");
PDF_begin_page($pdf, 595, 842);
PDF_add_outline($pdf, "Item".$data[1]);
PDF_set_font($pdf, "Helvetica-Bold" , 20, winansi);
PDF_set_text_rendering($pdf, 0);
PDF_show_xy($pdf, "OMG its a pdf on the fly!",50,780);
if (!isset($name)) {
$name = "Test Name";
}
if (!isset($age)) {
$age = "Test Age";
}
PDF_show_xy($pdf, "Your Name : $name" .$data[1], 100, 700);

PDF_show_xy($pdf, "Age : $age" .$data[2], 100, 620);

PDF_stroke($pdf);
PDF_end_page($pdf);
PDF_close($pdf);
fclose($f);
header("Content-length: " . filesize("test"));
$f = fopen("/tmp/test", "r");
fpassthru($f);
fclose($f);
?>

Only then did it work for me.

My php compiled ok, but phpinfo() forgot about phplib. I figured out the
libtiff on my box was not the right version. Very offset, I edited
manually configure file and erase all -ltiff or replace them with bogus
-lpng. Don-t care if -lpng wa duplicate. Php works fine now, with pdflib
and without tiff support.

Same as [email protected] only more info!!!!

(comments below are true as of 4.0.4pl1).
I kept banging my head on the "samples" that use PDF_new(). If
you check 
out the source tree comments on PDF_new(), PDF_delete(), and
PDF_open_file() and
you will see they are only available in the CVS tree.

The solution:

$fd = fopen("somefile","w"); $pdf = PDF_open($fd);
[...]
PDF_close($pdf); fclose($f);

You can't use PDF_new(), PDF_delete(), or PDF_open_file() until the
current CVS
source code tree is branched into a version release at least newer than
4.0.4pl1!

If you still can't get your pdf files to show up in IE 5.5, here is
something I found on phpBuilder:

1. Be sure to install the SR 1 for IE 5.5 
2. Be sure your running Adobe Acrobat 4.0 (not 3.0). 
3. Open Adobe Acrobat 4.0 by itself. 
4. Click on File 
5. Click on Preferences 
6. Click on General 
7. Deselect the option to: Web Browser Integration 

That should do it. This does not correct the problem of opening the files
directly in IE, but it's a great work around....and it works.

To continue on the internet explorer (Iexplorer, IE) requirements, instead
of content-length, a simple:
header("Accept-Ranges: bytes");

is enough for the getpdf.php file working right. Even Netscape will
without error with this modification.

An FYI for anybody else looking for pdflib help.  I got php-4.0.5 and built
pdflib-4.0.0 with 

'./configure' \
'--enable-cxx' \
'--enable-shared' \
'--enable-shared-pdflib'

I did make, make install and both make and make install complained that
there is  no makefile in pdflib-4.0.0/bind/php.  It works anyway, so dont
worry bout it. 
Then in php I used --with-pdflib=/usr/local and it works, this was
performed on a FreeBSD 4.2 Release machine

If you just have a look into the rep given, you'll see a nice readme.txt
saying you how to make this link working

When I use
$text='<align="center"><strong>Text
text!</strong></div>
';
....
and then
$num=pdf_show_boxed($pdfdoc, $text ....)
I get a problem with PHP: after 30 sek. says PHP... Timiout reached.
With other text (without HTML Tags) it works fine. Were is a problem
here?
Thanx for Answer.

With php-4.0.5 and pdflib-4.0.1 there is an error in the php source code
ext/pdf/pdf.c with function pdf_close_pdi_page wanting 3 args instead of
2.

To fix, copy the section for this function from the pdflib source 
bind/php/ext/pdf/pdf.c  and then it will compile.


Section from the pdflib source reproduced below:

/* {{{ proto void pdf_close_pdi(int pdf, int doc);
 * Close all open page handles, and close the input PDF document. */
PHP_FUNCTION(pdf_close_pdi) {
        zval **arg1, **arg2;
        PDF *pdf;
 
        if (ZEND_NUM_ARGS() != 2 || zend_get_parameters_ex(2, &arg1,
&arg2) == FAILURE) {
                WRONG_PARAM_COUNT;
        }
 
        ZEND_FETCH_RESOURCE(pdf, PDF *, arg1, -1, "pdf object",
le_pdf);
 
        convert_to_long_ex(arg2);
 
        PDF_close_pdi(pdf,
                Z_LVAL_PP(arg2)-PDFLIB_PDI_OFFSET);
 
        RETURN_TRUE;
}

With PHP-4.0.5 and PDFLib 4.0.1 the Error that do not compile in the php
compiling..

The error function in pdf.c is no PHP_FUNCTION(pdf_close_pdi) but
PHP_FUNCTION(pdf_close_pdi_page)

patch pdf.c in php-4.0.5. Like as below

PHP_FUNCTION(pdf_close_pdi_page) {
	zval **arg1, **arg2;
	PDF *pdf;

	if (ZEND_NUM_ARGS() != 2 || zend_get_parameters_ex(2, &arg1,
&arg2) == FAILURE) {
		WRONG_PARAM_COUNT;
	}

	ZEND_FETCH_RESOURCE(pdf, PDF *, arg1, -1, "pdf object",
le_pdf);

	convert_to_long_ex(arg2);

	PDF_close_pdi_page(pdf,
		Z_LVAL_PP(arg2)-PDFLIB_IMAGE_OFFSET);

	RETURN_TRUE;
}

I'm running Apache 1.3.20+PHP 4.0.6+PDFLib 4.0.1 and the 1st example given
above doesn't seem to work.  When I try it, I get:

Fatal error: PDFlib error: function 'PDF_set_info' must not be called in
'object' scope in
/usr/local/apache/htdocs/restricted/accounting/pdftest.php on line 4

Removing the filename and replacing it with "" seems to make the
page work fine again.

In reply to [email protected] comment about the 
"Fatal error: PDFlib error: function 'PDF_set_info' must not be
called in 'object' scope"

The reason why you get this error is because the directory you are saving
to does not have write permission.  Make sure that Apache (or whatever
webserver you are using) can actully write to your directory.

PDFLIB 3.0 won't work with PHP 4.0.6 because this version makes use of the
"imagewarning" parameter, available only from PDFLIB version
3.01. PDFLIB 3.03 works fine for me with PHP 4.0.6.

The demo version for windows (.dll) is purely for testing as their
enourmous watermark spanning the entire page diagnolly makes it completely
useless for anything else (that is what their liscensing suggests, I just
wanted to let everyone know in case you got comfortable with the
open-source concept.)

To make PDFlib PDFlib 4.0.1 work under PHP 4.0.6, you need to add the file
libpdf_php.so manually to the PHP extension library (as defined in
php.ini).

The file can be downloaded from www.pdflib.com. Just add it manually after
all the compiling stuff is done.

I thought the whole beauty of PHP was the fact that it is free.  So to find
out how much the PDFlib licence will cost me was quite a shock.  Is there
not a free API for building PDF documents ?

Cheers

Justing

Hi,

yes there is a free one:



Hope that helps a bit

You can also try  for a
completely free PDF-generating class. Not complete yet, but very
promising!

Right from their site:
The �Aladdin Free Public License�

 In short and non-legal terms:

* you may develop free software with PDFlib, provided you make all of your
own source code publicly available
 * you may develop software for your own use with PDFlib as long as you
don't sell it
 * you may redistribute PDFlib non-commercially
 * you may redistribute PDFlib on digital media for a fee if the complete
contents of the media are freely redistributable.

Is there a way to open a exiting pdf file  and add some text to it?

If you're wondering how to highlight words inside a PDF file, take a look
at this script I've written (doesn't need PDFLib)



It's a whole lot harder than you think. (Rarely has no much code been
written that does so little, that's what I say :-) Worth looking at if you
want to do searches inside a PDF.

Well it's nice to have a PDF function under PHP, but for several problems
PDFlib is useless. Here my problem I need a solution that create a PDF
file after I've had transformed a XML file with XSLT to XSL-FO. Executing
Apache-FOP with the "system" Command is not quite well.
Therefore I need to create a seperate channel to create PDFs. The
usability for transforming XML with XSLT in this case is poor. For
standealone project this lib could be quite usefull, but for XSLT
transforming I think a C++-dll-wrapper for XSL-FO->PDF after
XML->XSLT->XSL-FO is more usefull. Or what do you think about it?

Hope it can help someone:

Hi Guys

How can you encrypt a pdf document so that it is write protected.  You can
read it, but can't make modifications to the file, except if you have the
password.

Apparently this is a new feature that was added in Adobe Acrobat 5.0.

Thx
