Hi!

I am using amfchat from tufat.com, and wanted to integrate it with my
site's session data. amfchat uses flash remoting to communicate to the
server.

It initally sends

sessionid=time() to gateway.php

gateway.php starts a session using:

And accesses the session variables in another function thats called
using flash remoting.
as $_SESSION['username'];

I wanted to replace all this and I have made gateway.php start a
session as follows:
$prev_name = session_name();
session_start();

But I am not able to access my session variables in the functions
using $_SESSION['login']

This is the function I have modified:

        $session_name = session_name();
        session_start();
        $username=$_SESSION['login'];
        $password=$_SESSION['passwd'];

$result['description'] = "User= $username, Password: $password,
Session: $session_name"

When flash prints the 'result' arrary, the output for description is as follows

User= , Password: , Session: PHPSESSID

Can any one tell me if I am making a mistake some where or give me a solution?

Regards,
Yaswanth

Thanks Jay,

In the site of example I did in JS :)
I thought It would be improvement if there was something similar then I
could use it for other things later.

Thanks again,

Hi Dan,

You are sooo right. We know certain kindda people would love to break the
code just cuz its there :D

I am least worried about programmers. Its stupid rich Art collage kids I am
trying to prevent using my stuff. You would be amazed to know I walked in
SVA( School of Visual Arts), NYC & saw my painting exactly as is printed in
their merit list with a kid's name under.

What I want to achieve is, only my homepage will have File, View, Edit
menus. I have mapped navigation over images, once they go anywhere it should
open a window that has no menus like http://creative.gettyimages.com/ uses
for display of images.

I am not even sweating hot-linking.

Thanks a lot for the input,
C

As Dan has correctly pointed out, you can only hope to make stealing your
content "less convenient", though only marginally so. If you display a
picture on my browser, all I have to do to steal it is hit my "Print Screen"
button, then paste it into PhotoShop. There are any number of other ways to
get it too.

My guess is that Visual Arts students will be pretty good at manipulating
images on a computer, and that, unfortunately, you will not be able to
thwart a determined content thief.

PS Top posting here since it seems to be the "in" thing to do on this
thread.

I wish I had a dollar every time I've seen a question like yours, it seems
like a lot of new developers think they need to fundamentally alter the way
the browser works to protect their "content." The fact is, if you're
putting content on the public web, it can--and will--be downloaded by all of
your visitors. (they have to download it to display it after all)

You're going the wrong way about protecting your images. No matter what
Javascript tricks you try to use, all I have to do is disable Javascript.
And you're going to seriously annoy your visitors who are not technically
savvy, whether they have the intention to "steal" your content or not.
Personally I would not come back to a site that assumes I'm a thief.

You might want to look into other methods to protect your content, such as
login authentication and watermarking. PHP can help with these. But if you
come on this list and demand ridiculous things, don't expect to be taken
seriously.

A better way to ask your original question would have been: "How can PHP
help protect web content?"

Best,
Jason

Thanks Jason,

I am always ready to be enlightened by ones who know better than me.

As you suggested, I really would love to get a watermark which is invisible
with initial viewing but activated once a copying/printing command ( Can be
Ctrl+C or Alt+Printscreen) is used.

If you can help it would be delighting.

Thanks,
C

Once the browser has the content, it's out of PHP's hands. It's on the disk
of the remote client, and they can do what they like with it. To print an
image or web page that's in my disk cache, I don't need to use my web browser
- I can just go to the cache in my file manager and print it.

Unless you write a dedicated viewing application that must be used to view the
content, you're not going to have much luck.

If you want a watermark on print, just watermark the image anyway.

Steganography might help, but only in the digital world.

Are you sure you're tackling the right problem from the right angle?

attached mail follows:

Rather than trying to prevent theft of your images why not create a little
app that steganographs some copyright information... With some thought it's
possible to hide textual content within an image

At least then you can prove it was yours... Just a thought

New to mailing lists, aren't you? You're well on your way to breaking
every 'rule'...hell, you broke the number one rule just by asking the
question, as it's quite obvious what you _have not_ done.

I don't think you can, but you could have a single function that calls
both, then specify that function in ob_start().

[05-Dec-2005 07:40:33] PHP Fatal error: Call to undefined function
sqlite_open() in G:\apache2\htdocs\sqlite.php on line 9

I am running W2K professional, Apache 2.0.54, and PHP 5.1.0.

The CLI for version Sqlite version 3 is sqlite3, does that have anything
to do with the function names I should be using in PHP?

Any ideas, or point me to a cheat sheet.

I was getting php_sqlite module not found error when apache loaded. Then
I fixed the extension_dir setting. Next I got php_sqlite.dll could not
load because php_pdo module not found. I needed to include all of the
following dlls to get apache to load without complaint. I included the
php_pdo_sqlite because I am using sqlite version 3 CLI. Now it is working.

edited to:
extension_dir = "x:\php5\ext"

added:
extension=php_pdo.dll
extension=php_pdo_sqlite.dll
extension=php_sqlite.dll

HTH someone else.

Hi there,

I have been using the GD functions from PHP5.0 on Mac OS X.

I have a simple script that creates a PNG image with text on the image using
fonts using FreeType 2.

I am trying to use the imagettftext() function within a foreach loop but I
get the following error:

PHP Warning: imagettftext() expects parameter 2 to be double

The code is as follows:

$font['type']="./fonts/font.ttf²;

$font['color']=imageColorAllocate($card['png'],$font['hexcolor']['r'],$font[
'hexcolor']['g'],$font['hexcolor']['b']);

imageFill($card['png'],0,0,$card['color']);

foreach ($xml->textblock as $text) {
$fontsize=$text->fontsize; $fontangle=$text->fontangle;
$fontxpos=$text->fontxpos; $fontypos=$text->fontypos;
$text=$text->text;
imagettftext($image['png'],$fontsize,$fontangle,$fontxpos,$fontypos,$font['c
olor'],$font['type'],$text); }

It works fine if I add just one line outside of the loop but as soon as
its within the loop it errors.

Cheers,

James

Hello,

I'm having a problem with certain SSI files which include php scripts
after upgrding php from 4.3.10 to 4.4.1.
The includes look like:

In some cases, the page output is different with 4.4.1 than it is with
4.3.10. In the worst cases, Apache gives a segmentation fault, and
the page is blank.

Has anyone encountered any similar issues?

Thanks,
Kristina

We'd have to see some code to begin to analyse what the problem might be.
Can you send php code snips from eventdb.php?

The code is short. The same php script is being included in the page
which is displaying differently and the page which is causing the
apache segfault.

if (empty($ID)){
    $ID='1';
}
$today = date("Ymd");
$conn = mysql_connect ([snip]);
if ($conn == false){
  echo mysql_errno() . ": " . mysql_error() . "<BR>";
  exit;
        }
else {
                        $rtn = mysql_select_db ("[tablename]");
                        $sql = "select * from events where ID = ".$ID;
                                                $result = mysql_query ($sql);
                        if ( ($row = mysql_fetch_row($result)) &&
($today<=$row[4]
) ){
                                                        //if ( $row =

                                                        case 2:
                                                        echo $row[2];
                                                        break;

                                                        echo $row[7];
                                                        break;

                                                        break;
                                                          }
                                                }

}

By the way, the backtrace from the apache segfault is:
#0 0xb7e095cc in zend_hash_index_update_or_next_insert (ht=0xb7ea29c0, h=0,
    pData=0xbfffdc60, nDataSize=12, pDest=0x0, flag=1)
    at /home/sys/src/php-4.4.1/Zend/zend_hash.c:390
390 p = ht->arBuckets[nIndex];
(gdb) bt full
#0 0xb7e095cc in zend_hash_index_update_or_next_insert (ht=0xb7ea29c0, h=0,
    pData=0xbfffdc60, nDataSize=12, pDest=0x0, flag=1)
    at /home/sys/src/php-4.4.1/Zend/zend_hash.c:390
        nIndex = 0
        p = Variable "p" is not available.
(gdb)

That segfault backtrace is the same even if I compile php with the
--without-zend-memory-manager flag, and also when I disable all Zend
settings in php.ini.

Probably not a PHP problem. And probably can't help without seeing
your redirect code. I've never had a problem with redirects in any
browser Safari or otherwise, but I always make sure I redirect with a
full URL rather than a relative URL.

Trying to validate input so it is valid in what ever context it may
be used in is probably the wrong mindset. You should think in the
terms of ensure this string wont cause any problems in the medium
you are outputing it to. For Example.

You have a string that is being passed in from a html input field
such as:
$_GET['string'] = "O'rielly <script>...</script> <?php echo 'foo';?>"

So the question is where are you planning on putting this?
  1) A DB?
    you will need to escape the string so it wont cause any
    problems with the output to mysql:

$string = mysql_real_escape_string($_GET['string']);

  2) The browser?
    you will need to escape the string so it wont cause any
    problems with the output to html:

      $string = htmlentities($_GET['string']);

  3) For some reason want to eval() it?
    you will need to escape the string so it wont cause any
    problems with the output to php:

      // assuming short tags, asp tags etc are disabled...
      // remove <?php and ?>
      $string = preg_replace('/(\<\?php|\?\>/', '', $_GET['string']);

So it comes down to the fact that the standard technique is to
ensure that the data you are sending, to what ever medium, is
properly escaped.

The same output escaping should be considered no matter the input
of the data ie: database, rss feed, flat file ...

Hi,

actually I think that if you have performance problem is when you make the
calculations and process. If you make processes while giving output to the
client, you might have some problems whether being somehow output buffering
dependant... I would rather leave the output management as final step,
concentrating all the process in the first part "hidden" and not involved
into the parsing of HTML code (useless).

I rather prefer the approach of

data entry/input -> process -> output

instead of

data entry -> output while processing

especially when the performance of process is critical. Do essential first,
have fun laterz =:)

Obviously IMHO :)

Have fun,

All you need to do is redifine what the $_SESSION['client'] array's
definition is:

$_SESSION['client'] = array('name' => $_SESSION['client']['name']);

>

Don't mix session_*register() functions with the use of $_SESSION.
Those functions are only there for old scripts to work, see
http://php.net/session_unregister (the second Caution)

To register a session var:

$_SESSION['client'] = $client;

To unregister a session var:

unset($_SESSION['client']);

                  return FALSE;
               }
               die(mysql_error());
            }

            return $result;
         default:
            $err = ERR_INVALID_ACCT_STATE;

Some specific questions I have are:

1) It seems mysql_connect can "die" internally. At least this is what I
see if the username or password is incorrect. Is there a way to suppress
that behavior so that I can display an appropriate message rather than
too much information or nothing?

2) Must I always call mysql_select_db or can that be folded into the
connect or somehow specify a default db in some settings somewhere?

3) I use a global $err and define() custom ERR_* strings to communicate
errors similar to errno in C. Is this a respecible method or is a
different technique preferred?

4) Can I rely on mysql_errno() values as I do above to determine if a
username already exists (1062 is the value returned by mysql_errno()
when trying to insert a record with a username that already exists).

Note that I call $acct->store() and handle the error. Is this the
preferred technique? It seems redundant and racey to query the database
to determine if the username exists and then insert if available.

Thanks,
Mike

It seems so, but the issue is still present in 1.5 and might be
further on.

session_cache_limiter('private') changed the output from

session_cache_limiter('private_no_expire') can get rid of the Expires
header as well, but it doesn't seem to be an issue here. It could
still be relevant for other reasons though.

Does anyone know of a good GD tutorial for creating graphs? I'm
looking to create something like the attached one by feeding it the
values and have it create the graph. Possibly with multiple lines,
different colors, different types of data, etc., etc.

You may have alreayd looked at this class, but this one is great for
creating graphs:

There are some licensing issues with it so if this is for a company then you
probably have to buy a license.
