Hi Tom,
Have a look at the library called 'pChart':
http://pchart.sourceforge.net/
While it's a bit old, it generates very nice looking (anti aliased)
charts, using the default GD library.
Regards,
Mattias

Subject: [PHP] Bar Charts in PDFs
Hi
I need to generate some PDF reports (1000s). Part of the report is a set
of
bar charts (the results of a questionnaire). Each question has the same
5
answers (v.bad, bad, ok ,good, v.good) and the chart is the %
distribution
of the answers.
My plan is to create a HTML version, using "some graph drawing"* (saving
a
copy of the HTML to disk), creating a PDF version using html2pdf (saving
a
copy to disk and emailing to the recipient).
I think html2pdf can handle this. But I have not had much success
finding
something to draw my graphs. Any (free) simple libraries out there I
could
be pointed towards?
Thanks!
Tom

For the PDF production, I'd recommend looking at fpdf [1]. A free PHP
class that doesn't use any libraries.
It can easily take the image you've created using Mattias's suggestion.
I use the fpdf class to take fax documents and add various report data
to it and subsequent pages. All fairly simple stuff.
Regards,
Richard.

Actually, it's been updated to v2.1 now. It looks pretty nice.

Sweeeeeeet... good to know. I recently used this and had to hack in
support for missing features (mostly different line types for each data
set). Hopefully there's better support for that now.
Cheers,
Rob.

Tom:
You can try:
http://www.tcpdf.org/ to generate pdf.
And http://jpgraph.net/ To generate chart.
EX: to add a image to a pdf document:
$pdf->Image( '/home/peter/test.png',
127.78, 15, // left and right
74.93, 6.42, // width and height
'PNG', '', 'T', false, 300 );
With this tcpdf i create a legal documents for Brazilian government.

well, first off i should be using php:flush() instead of
php:ob_flush() in my simple test.
second;
http://www.php.net/manual/en/function.flush.php :
....
Several servers, especially on Win32, will still buffer the output
from your script until it terminates before transmitting the results
to the browser.
.....
aargh..
well, i'll have to dig deep here.
will inform you of any relevant progress, digest style

BUYAKAA! This fixed my problem in the simple test AND in my application!
No need to send keep-alive bytes on the text/html level either.
I just added the "KeepAliveTime" setting with windows 7 regedit.exe in
HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/services/Tcpip, as a
REG_DWORD value, set it to decimal 25000 (so 25 seconds), rebooted,
and it all works as i want it now..
Note that windows registry entries key names are case-sensitive, wrong
casing and they'll be deleted on restart.
Lots of thanks, Daniel. I would've never solved this on my own..
I'll make an entry in the php.net website "comments" about this.

Hey all -
I'm using mcrypt to store credit cards into MySQL. About 90% of them decrypt
fine, but about 10% decrypt as nonsense ("b1�\�JEÚU�A���" is a good example).
Maybe there is a character that appears in about 10% of my encryptions that's
not being encoded properly???
// Encryption is set up at the top of the script:
$crypto = mcrypt_module_open('rijndael-256', '', 'ofb', '');
$iv = mcrypt_create_iv(mcrypt_enc_get_iv_size($crypto), MCRYPT_DEV_RANDOM);
$ks = mcrypt_enc_get_key_size($crypto);
$key = substr(md5('my_funky_term'), 0, $ks);
// When the card number is collected by the form, it's encrypted:
$cc_number = addslashes($_POST['cc_number']);
mcrypt_generic_init($crypto, $key, $iv);
$cc_encrypt = mcrypt_generic($crypto, $cc_number);
mcrypt_generic_deinit($crypto);
// This is written to the database:
$query = "update accounts set cc_encrypt='$cc_encrypt', encrypt_iv='$iv',
other_fields='$other_stuff' where id='$account_id' limit 1";
$result = mysql_query($query) or die(mysql_error());
Both the cc_encrypt and encrypt_iv fields are tinytext, latin1_swedish_ci,
MyISAM, MySQL 5.0.91
In another script, when I retrieve, I first set it up at the top of the script
exactly like step #1 above, then retrieve it like this:
mcrypt_generic_init($crypto, $key, $row['encrypt_iv']);
$cc_number = trim(mdecrypt_generic($crypto, $row['cc_encrypt']));
mcrypt_generic_deinit($crypto);
Most of them are good, a few of them are bad. Can anyone see anything I'm doing
wrong or a case I'm not covering? Thanks much.
