PNG's support transparency as well as GIFs.
The short answer is that you'll create your image and also specify a color
that will be made transparent. I don't see why imagecreatetruecolor making a
default black image is a problem? If it is, just set black to be the
transparent color and go from there.
This is your friend:

If you want to create a transparent image don't forget it must be a GIF. At
least that's what my graphics guys have been telling me all these years :)

hello,
What is the better way to read from a pipe from a php cli script?
#! /usr/bin/php -q
<?php
$stdin = fopen('php://stdin', 'r');
while (!feof($stdin))
$buffer .= fgets($stdin, 4096);
fclose($stdin);
?>
or
<?php
while ($stdin = fread(STDIN, 4096)) $buffer .= $stdin;
?>
I have tryed these ways, but the problem is that if there is no pipe input,
the script is waiting for ^D from the user (so this is a problem if the php
filter is used in a bash script, because it will block the process).
How can I detect if there is an stdin from a pipe or not?
I have tryed this but it does not work:
stream_set_timeout(STDIN, 1, 10);

Just FYI -- if you've searched for information on a spell checker, I'm sure
you saw Jspell -- <http://www.jspell.com/jspell.html>. It's Java and
Javascript, but I found it fairly easy to add to a PHP CMS.

Hi...
I stopped here in my program :
I want to make a PHP page that reads from a mySQL Database.. This page displays two
fields for the user : 1- Username. 2- Password.
Now in the database there are many columns.. each one has many fields :
Username, Password, Serial, Phone No., Address..Etc..
Now I want the PHP file to take the Username and Password after the user enter them in
the fields and compare them with the ones inside the database.. if they are the same..
the serial field inside the database will send its value to the PHP page.. which will
echo it as a variable ($var) there..
So every user has a column that has..
Waiting your replies..

You didn't specify whether you and your client are using the same
server. If not, make sure you have the same gpc slashing settings on
both servers.

Hi all,
I m undergoing a very weird kind of file uploading problem. I m trying to upload an image file and a pdf file using HTTP Upload form. Now my client is complaining that pdf file is getting corrupted during uploading as they do not open once uploaded. But when i try to upload(using WinXp home, I.E 6+) from my end every thing works perfectly ... so its very surprising for me.
Initially when client complained (using WinXp home editon , I.E 6+) , i thought it is some browser issue and hence instructed them to upload pdf using Win2K machine. But they are facing the same problem there also. I don know wht to do..
Any of u guys faced this sort of problem plz tell me where exactly is the problem? Why the pdf files are getting corrupted? is there some thing hidden which is causing the corruption?
Thanks in advance

Why create thumnails? You can resize the images on

If you mean resize with <img /> tag then you are wasting bandwidth. If
you mean resize by creating the thumbnail at request time, then you are
wasting processing time. Unless the thumbnail is requested very
infrequently then it is usually better to have a pre-resized image, than
to resize it on the fly.

Rob.

This would be too expensive.
I need to store the thumbnails in the database.
So, I need to resize the image at the same time as I store it.
I can do this and save the thumbnail in the file system, but
cannot save the thumbnail in the database.
Kind regards

This is a known issue with IE. And it is in their knowledge base. If I
recall the fix is to clear the cache, cookies, and broken/corrupt
objects.

Again, it is *not* that known issue. That's the very first thing I checked.
If that were the issue, jpgs from other sources would also not save
properly. But they do, as I've stated several times.
Thanks, though.

try adding showpicture.php?pid=111384&img=x.jpg to the end even though you
aren't using that variable, IE may see that the type is jpg here. I have

I have the same problem. Strange: I have a session_start(); before the
header... if I take that out, the image will download as a JPG... so maybe
if you find a way to do things in this script without starting the session
first...

We are not here to write your project for you. Plenty of people have
already told you to download the documentation and get yourself some
good books on the subject. It is becoming clear you have no wish to

Matt,
You're not by any chance using an Apache server on a machine that also has a firewall,
are you? I've had all sorts of mysterious session-related problems when running
scripts
on my test server (Apache on Win2k with a ZoneAlarm firewall). Took me *ages* to zero
in on the source of the problem. Now whenever I need to test a script that involves
sessions, I simply disconnect from the internet and shut down my firewall.
Cheers,
Erik

So every user has a column that has..
So which actions must I use.. and which lessons are important for me at the moment?

Whatever do you want to do that for? What do you need (or want) to accomplish? What
kind of project is this? Give us the big picture!
> So every user has a column that has..
That has...?? Your unfinished sentences presume telepathic powers that few of us
have. :-)

What exactly do you expect the people on this list to do for you? Help you with your
project because you're running out of time? Most of us are very busy too, so take it
nice
and easy.
Have you opened the book that you've bought and had a look at its table of contents?
Have you read the introduction? Authors usually tell you in the introduction which
parts
you absolutely must read to get up and running. Assuming that your book has a section
on PHP, a section on MySQL and a section on PHP interacting with MySQL, you'll
probably want to read the first few chapters in each section.
When you have a better idea of what it is that you want to accomplish and stumble on a
problem that you can't solve, then by all means post a question to this list —
preferably
with a title that reflects the issue you're addressing, not the urgency of your
personal
needs.
Good luck,
Erik

It actually does not work.
Could you explain what, exactly, does not work?
I am trying to load a PDF file. I've tried
to load it from a protected directory loading it with headers, but this
fails if the protection is on. Does this make sense to you?
The above outlines a scheme which is workable. Could you describe the steps
you took to implement said scheme which lead you to the conclusion that "It
actually does not work" ?
Yes, sorry. Here is the code: $file =
'http://miningstocks.com/protected/archive/Dec03PostPress.pdf'; //now
view the PDF file header("Content-Type: application/pdf");
header("Accept-Ranges: bytes"); header("Content-Length:
".filesize($file)); readfile($file); I can send the rest if necessary.
You can see the results yourself of this:
http://miningstocks.com/enteremail.php (just enter [EMAIL PROTECTED] for an email
address). Yet, when I have changed the $file to hold a path that is not
protected through http auth. it works perfectly fine and loads the file.
