Mike. I would start by confirming that the pdf library has been
enabled/loaded successfully. Call phpinfo() and look for the pdf
library. It should be there. Since I am on Mac OS X, I am not sure
what php_cpdf.dll/php_pdf.dll really is (pdflib? - why two
libraries?). Anyway, the error you get indicates that the pdf
extension hasn't been loaded successfully. Did you restart the server
after enabling it?
Regarding the printing issue, assuming that you are on Windows, there
is a PECL extension called php_printer.dll that should do what you want.
For download: http://pecl4win.php.net/ext.php/php_printer.dll
Documentation: http://se2.php.net/manual/en/ref.printer.php

I am trying to get a query to run and outputed to a pdf file I get the
following error
Fatal error: Call to undefined function pdf_begin_document()
in my php.ini I have php_cpdf.dll and php_pdf.dll enabled am I missing
something.?
also is there a way to send the document I create to the printer
instead of
the screen?

in the email. It should be all on a single line.
$result = fread($fp,102400); // Reads 100KB, change if you need more
echo $result;
Now when I try that I get a "Bad Request invalid header name" error.
I have an IIS server running localy on port 8080, the Project1.dll is in the
root directory, it contains two input components 1 a textfield to type your
name, the other a checkbox called likes. What's wrong? Here's it's code:
<snip code>
It has nothing to do with your code, you have made an invalid request,
if the above is correct, then the Host: header must be wrong, I'm not
sure what it should be for localhost, but if above doesn't work, try
127.0.0.1.

it would be upto the ISAPI code to 'publish' a COM interface to its
functionality. in php you merely start a COM session by creating a COM object
that inits the functionality offered by the ISAPI code by way of the passed in
'modulename'
... the functionality available via the php COM object interface is dependent on
whatever the ISAPI exposes via COM.
try also searching for ISAPI and OLE combinations.
I'll be honest and say that I'm just stabbing in the dark, but it just seems
right that
you should be able to talk to the ISAPI interface somehow withit involve the
network stack
or HTTP.
goodluck.

The Secure Systems Lab at the Technical University of Vienna has released the
newest version of Pixy, an open-source vulnerability scanner. Here are some of
the highlights:
- detection of SQL injection and XSS vulnerabilities in PHP source code
- automatic resolution of file inclusions
- computation of dependence graphs that help you understand the causes of
reported vulnerabilities
- static analysis engine (flow-sensitive, interprocedural, context-sensitive)
- platform-independent (written in Java)
Pixy can be downloaded for free from http://pixybox.seclab.tuwien.ac.at/. There,
you can also find a web interface that allows you to test Pixy online. Enjoy!
We would be happy to receive feedback, comments, and other contributions! Please
send your suggestions to "pixy-tool at seclab" (domain see below).

Hi. I have been asked to try to catch the php error generated when the
PHP script exceed execution time, but I do not know if that can be
done... Any ideas? Mainly I want to show a custimized error page instead
of that error (kind of "Sorry but we are busy right now" or something
similar)
Thanks.

Depends what the error is. See http://php.net/set_error_handler for details.

I'm currently creating a socket cerver class, similar to Twisted for
python. I have a simple socket server working now, but would like to
extend it using threads.
I've done a fair bit of research on threads in PHP in the past, but
coming up to the conclusion that there is no way to have real multi
threading in PHP.
Would anybody here know of any way to use threads in PHP that I may have
missed? I'm hoping to find a way that would work on most OS's without
any major changes.

You could look iinto using ticks or forking new processes using pcntl,
but that's the limit.

Hi all
I'm new to this list. I hope this hasn't been discussed already.
using this code:
function test_time($time_string) {
echo strftime("%X %A, %b %e\n", strtotime($time_string));
}
test_time('now');
test_time('4pm + 2 Hours');
test_time('now + 2 fortnights');
test_time('last Monday');
test_time('tomorrow');
test_time('5am tomorrow');
test_time('7am 12 days ago');
gives this output:
21:46:18 Wednesday, Jun 20
18:00:00 Wednesday, Jun 20
21:46:18 Wednesday, Jul 18
00:00:00 Monday, Jun 18
00:00:00 Thursday, Jun 21
00:00:00 Thursday, Jun 21
07:00:00 Friday, Jun 8
I'm wondering why the 2nd and 3rd last both give 00:00 as the
time. Especially why 5am tomorrow doesn't work. Using PHP5.
Thanks
Phil P.

If I have a record that matches Level4 it will display both with the

I don't think IF is the culprit. I'm guessing you have a bad join in
your sql query so you are getting back more records than you expect.
Have you run the query directly in to see what your results are?
Hi Roberto,
Thanks for the reply! The query I'm using to grab the records from
MySQL is a very simple one:
$sql = "SELECT * FROM tasks WHERE completed='0' order by id";
I don't totally understand yet why it happened, but Jim's suggestion
worked great.
Thanks though!

nope, couldn't guess why.
I would look at your result set and see if you had multiple lines
returned. One person mentioned that you might be using a JOIN in you
SQL call. This could lead to multiple lines.
Start investigating your SQL statement I would suggest.

depends on what format do you have $start_date in
if you have something like 2007-02-01 then you could use
$parts = explode('-', $start_date);
$start_year = $parts[0];
$start_month = $parts[1];
$start_day = $parts[2];
or you could use substr like
$start_year = substr($start_date, 0, 4);
$start_month = substr($start_date, 4, 2);
$start_day = substr($start_date, 7, 2);
and you have several other options also, like strtotime() etc ;)

Of course depending on what $start_date looks like, but this should work
most of the time:
$timestamp = strtotime( $start_date );
$start_year = date( "Y", $timestamp );
$start_month = date( "m", $timestamp );
$start_day = date( "d", $timestamp );

If you are pulling $start_date from a database, depending on the format you
could use something like the following:
Assuming the data is 20070215.
Connect and query your database, get the result and assign it to a variable.
$start_date = $my_result_row['start_date'];
$start_year = substr($start_date, 0, 4);
$start_month = substr($start_date, 4, 2);
$start_day = substr($start_date, 6, 2);
Now you will have variables for the entire date, the year, the month and the
day to play around with however you want.

I'm adding all of that stuff in. As of now, the user can change
their name by typing:
/nick name
.... but there may still be some bugs. I've only put about two
hours of work into it so far, so there's a lot of stuff left undone.
