Phillip,
I use ezpdf (http://www.ros.co.nz/pdf/). I've been using it for
years and have found it very capable of making any PDF I want.
Take care,
Floyd

Currently, we use DOMPDF to generate PDFs from HTML. However, it's
no longer maintained and it has a few bugs that we just can no
longer live with. What PDF generating software do you use? It does
not have to be free, but it must run on linux and may be command
line or run through code. Some of the ones I have researched are...
html2pdf
html2ps
html2fpdf
xhtml2pdf
fpdf
tcpdf
You're thoughts would be appreciated. Oh, my preference would be to
send HTML/CSS to a script and it just automagically convert to PS/PDF.
Thanks,

This one seems fairly neat. However, it appears as though the author
no longer keeps up with it - last entry on 6/17/2006. Have you ever
run into any problems or setbacks with it?

Nope. I've never had any troubles with it. I've been able to produce
all kinds of PDFs including loan agreements, inventory pick lists with
barcodes, and various others. I find it incredibly powerful and easy
to use.
Take care,
Floyd

I've been using fpdf for 4-5 years for invoices among others and are
very happy with that.

I've been using ezpdf for many years and I think it is still the best option
available.

I need to know if there is _any_ connection available, not a specific
connection. In one script it may be $link but in another $connection.

Of course they connect differently, each to a different database (all
on localhost).

Dotan,
You are making this thing harder then it has to be.
All you need is to replicate the escaping of the same characters that
mysql_real_escape_string() escapes. Simply do that. They are listed on the
functions manual page on php.net
http://php.net/mysql_real_escape_string
Here is a function that I mocked up really quick.
I have no idea if it will work, but it is a start down the right road to solve
your problem(s)...
<?php
function clean_string($input) {
/**
* Character to escape...
* \x0 \n \r \ ' " \x1a
**/
$patterns = array( "\x0", "\n", "\r", "\\", "'", "\"", "\x1a");
$replace = array( '\\\x0', '\n', '\r', '\\\\', '\\\'', '\\"', '\\\x1a');
return str_replace($patterns, $replace, $input);
}
?>

Hello everyone,
I post a message here because i didn't find any solution yet.
I just finished video streaming service on my website. I use xmoov
script (http://xmoov.com/xmoov-php/) to do that. It works like a
charm, but I find an issue. When the video is buffering into the
flash player, all others requests are pending until the video is loaded.
I discovered in my search that fopen() function could block php process.
Does someone know this problem ?
I've had a similar problem with zip downloads (which also use fopen),
I supect either the headers, a caching problem or latin1/utf-8
What does your headers look like? (firefox has a lovely plugin "live
http headers")
Which character encoding do you use?
Show us code bit from fopen to fclose
I forced charset encoding in my htaccess to ISO-8859-1.
Here's the http headers I receive :
Expires: Thu, 19 Nov 1981 08:52:00 GMT
Cache-Control: no-store, no-cache, must-revalidate, post-check=0,
pre-check=0, max-age=0
Pragma: no-cache
Last-Modified: Mon, 19 Oct 2009 19:00:33 GMT
X-Pad: avoid browser bug
Content-Length: 14145470
Vary: User-Agent
Keep-Alive: timeout=5, max=100
Connection: Keep-Alive
Content-Type: video/x-flv
And here's the php code :
if (($fh = fopen($file, 'rb')) === FALSE)
return;
# assemble packet interval
$packet_interval = 0.3;
# assemble packet size
$packet_size = STREAM_SPEED * 1042;
$seekPos = intval($seekPos);
$fileSize = filesize($file) - (($seekPos > 0) ? $seekPos + 1 : 0);
session_cache_limiter("nocache");
header("Cache-Control: private",false);
header("Expires: Thu, 19 Nov 1981 08:52:00 GMT");
header("Last-Modified: " . date("D, d M Y H:i:s") . " GMT");
header("Cache-Control: no-store, no-cache, must-revalidate,
post-check=0, pre-check=0, max-age=0");
header("Pragma: no-cache");
header("Content-Type: video/x-flv");
header("X-Pad: avoid browser bug");
header("Content-Length: " . $fileSize);
# FLV file format header
if($seekPos != 0) {
print('FLV');
print(pack('C', 1));
print(pack('C', 1));
print(pack('N', 9));
print(pack('N', 9));
}
# seek to requested file position
fseek($fh, $seekPos);
# output file
while(!feof($fh)) {
# get start time
list($usec, $sec) = explode(' ', microtime());
$time_start = ((float)$usec + (float)$sec);
# output packet
print(fread($fh, $packet_size));
# get end time
list($usec, $sec) = explode(' ', microtime());
$time_stop = ((float)$usec + (float)$sec);
# wait if output is slower than $packet_interval
$time_difference = $time_stop - $time_start;
if($time_difference < (float)$packet_interval) {
usleep((float)$packet_interval * 1000000 -
(float)$time_difference * 1000000);
}
}
fclose($fh);
Thanks for help.
I solve the issue. I forgot to close the session before sending the stream.
Add session_write_close(); before sending.
In hope it may help.
Cheers.

This has been solved today. Talawa had a similar problem and came up
with a solution to his problem, namely using session_write_close()
before creating the headers. That stunt also solved my problem :-)

Hi PHP people
I have a really strange and annoying problem. I've got a site, where
members can download music. User clicks index.php (in index.php
there's an iframe, that opens another file), if certain check are okay
then a popup window opens download.php, where a mp3 file is fetched
from the server and renamed in the header, then pushed to the enduser,
this works fine. But now I want to create zipfiles too but when a user
downloads a zipfile it's like the whole site is freezed until download
has completed. My guess is that this is some sort of header problem
(see headers below), due to three headers at the same time, cause the
class works as expected in the test page i've created. Inputs to
correct headers would be appriciated very much :-)
Mp3 headers:
$new_filename = "attachment; filename=\"{$artist} - {$title}.mp3\"";
header('Content-Description: File Transfer');
header("Content-Type: application/octet-stream");
header("Content-Length: $size");
header("Content-Disposition: $new_filename");
header("Content-Transfer-Encoding: binary");
readfile($source_file);
Zip headers:
$zip = new zipfile();
$zip->add_dir(".");
$new_filename= "{$artist} - {$title}.mp3";
if(mysql_num_rows($result)) {
$zip->add_file($file, $new_filename);
}
header("Pragma: public");
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Cache-Control: private",false);
header("Content-type: application/zip");
#header("Content-Type: application/octet-stream");
header("Content-disposition: attachment; filename=\"zipTest.zip\"");
header('Content-Transfer-Encoding: binary');
ob_end_clean();
echo $zip->file();
Code example: http://lps.netlinq.dk/test010/test_zip.class.php
Headers (fetched with firefox add-on: live http headers)
This is headers from the site, where the problem occurs:
1. click on the link to a title (Maxwell in this case)

Hi,
I'm writing a program to record the system calls my web application places
by interposing the libc libraries. However, I noticed that none of the
system calls generated by the MySQL module in PHP is being recorded. I did
ltrace and it seems like the module is statically linked, but doing "file
/usr/lib/php/modules/mysql.so" says differently. I'm using Fedora 11 and
wondering if PHP is statically linked or not by default?
Thank you.

Hi,
Most likely your machine has a borked zlib library. Try:
pear install -Z DB
This will download the uncompressed .tar and should work fine. If it
does, look to fix your zlib install and re-build PHP.

Ha, I guess I should wait before replying :).
It is zlib's fault. We've had reported problems for years on some
poorly configured systems (not your problem: several distros decided to
include a borked zlib and apparently some still do for no good reason at
all).

Hi,
The error I posted about the other day, "PHP has encountered an
Access Violation at .", is recurring on an intermittent basis. I find that
once it starts occurring, it continues happening for about an entire day,
and then it mysteriously stops occurring again for a day or two.
I am running PHP on a commercial server at Hostway.com, so I
don't have the ability to reboot the server as a test. Nor do I think I have
the ability to check PHP error logs or ini files on my own. I've written to
Hostway support about the problem and am waiting for their reply, but I'm
afraid they might just tell me it's a programming problem they can't help me
with.
I have reduced the problem to a very simple script that shows it
occurs on a call to "file_get_contents()" on a URL. It can likewise occur on
calls to "simplexml_load_file()". Note that the problem is not directly
caused by these function calls because I can run scripts with those calls
over and over again until suddenly the error starts occurring without any
discernible cause. Even after the error does start occurring, it does not
occur when I call "file_get_contents()" on a file, only on a URL, but the
URL does not have to be valid, so the problem is not being caused by actual
data transfer in an open stream.
See below for the code that yields the problem, when the problem
is occurring, along with two example outputs from it, and with links to the
script running on the server so you can see the problem yourself, unless the
intermittency phase is that the error is not being generated at the moment
you try it! The second example shows that the problem occurs without
successfully opening a stream. It seems to me that this means the problem is
somewhere in the server that my script is running on, not caused by any
connection to another server.
An additional detail. The problem started happening after I
started using the Google Maps API to access data on mailing addresses via
calls of the form
simplexml_load_file("http://maps.google.com/maps/geo?output=xml&key="; .
GoogleKey . "&q=" . urlencode($sAnAddress));
I wonder if the problem is caused by something the calls to Google do to
affect the server over time, so that the error is not directly caused by any
single such call, but by the cumulative effect of hundreds of such calls in
some mysterious way.
Does anyone have any idea what is going on or how to test or
check things on the server to figure out what the problem is?
Stumped,
Marshall

I second that and make sure you add an SPF Key to your domain:

You should be able to get the SMTP limits from your host and these can be
configured in PHPlist.
The bounce handling takes away a lot of admin work once your list starts
getting larger and people's email addresses change/stop working.
