Woof.
Okay, restricting oneself solely to GD 1.x (gak) and PHP 4.1.2 does
change the ground rules quit a bit...
Honestly, your BEST bet is getting current GD and using one of the
pre-existing galleries.
That said, the two requirements you gave initially:
slide show
thumbnails
are both completely do-able in GD 1.x
SLIDE-SHOW:
<?php
//Change the next 2 lines for sure:
$path = "/full/path/to/your/photo/directory/here";
$url_path = "/just/from/homepage/to/your/photo/directory/here";
$dir = opendir($path) or die("Could not opendir $path");
if (!isset($_REQUEST['file'])){
readdir($dir); //skip dir commonly known as "."
readdir($dir); //skip the ".." also
$file = readdir($dir); //should be a real image
}
else{
while (readdir($dir) != $file){
//do nothing, just skipping merrily along to find the file
}
//Okay, that was the image they just saw. Show the NEXT one:
$file = readdir($dir);
if ($file === false){
//They have seen the whole show... Start over? What?
//You get to code this part yourself.
}
}
?>
<html>
<head>
<title><?php echo htmlentities($file);?></title>
<meta http-equiv="refresh" content="1;<?php echo
$_SERVER['PHP_SELF'], "?file=", htmlentities(urlencode($file))?>"
/>
</head>
<body bgcolor="#ffffff"><table width="100%" height="100%"><tr><td
align="center">
<img src="<?php echo "$url_path/$file"?>" /></body>
</td></tr></body>
</html>
For making thumbnail, see http://php.net/imagecopyresized
That was in GD 1.x
The cooler, better, much nicer-looking imagecopyresampled came in 2.x,
I think.
There's a BUNCH of notes and examples there for this bit, so I'm not
typing another one.

Hi!
I've got a very strange issue that is basically cutting off session variable
data after 1 character. When I set the session variable as "50" it comes
back as "5". When I set it to "XYZ" it comes back as "X". I have a script
that is taking $_GET['State'] variable and setting it to a session variable
named $USER['State']. This worked fine until a few days ago, but now it's
persistent! Any ideas what might be causing this?? I've searched the
web/lists and can't find any reference.

Hi,
I am having a problem with my system when sending e-mails to yahoo
accounts, and it has been baffling me for the last couple of days,
actually I should say it is driving me crazy...
As I mentioned, I have a cpanel and have 2 domains/sites with
dedicated IP addresses on my system. The base account has domain name:
host.mydomain.com with IP address, let's say is x.x.x.x, the first
domain first.com is x.x.x.[x+1], the second domain second.com is
x.x.x.[x+2]. And, as you know, all e-mails for both domains are sent
from host.mydomain.com with source IP as x.x.x.x
Now, I wrote a php script, and placed it on both sites. It is exactly
the same script, with only one difference, from address, reply-to
address, etc. are set to [EMAIL PROTECTED] for the first domain and
[EMAIL PROTECTED] for the second domain.
When I execute this script, it sends an e-mail to a yahoo address. The
problem is: the e-mail sent from first.com is sent fine meaning it
reaches the recipient Yahoo INBOX, but the one sent from second.com is
dropping into Yahoo's Bulk Folder...
For the second domain, I tried sending e-mail for that domain from
another hosting service, and that one got into the INBOX, not Bulk...
Both first.com and second.com have proper A records and MX records.
host.mydomain.com has an A record setup, and mydomain.com has an MX
record setup (pointing to some other mail server)...
Now, this is very confusing because:
1. If my hosts IP address (x.x.x.x) was blocked, then both
[EMAIL PROTECTED] and [EMAIL PROTECTED] should be blocked, but one of
them is reaching its destination, while the second one is tagged as
SPAM.
2. If there was a problem with the way SMTP is configured, again both
should not have been dispatched. In fact, EHLO domain
(host.mydomain.com) is resolving to source IP (x.x.x.x) and source IP
(x.x.x.x) is resolving to the EHLO domain (again host.mydomain.com)...
And, two headers are almost same (other than return-path, etc. of
course)
3. If [EMAIL PROTECTED] (or the whole domain second.com for that
matter) e-mail address(es) was/were blocked, then both mail sent from
x.x.x.x and other hosting service should have been blocked. But, as I
mentioned, other hosting services e-mail goes thru fine!
Can someone please shead a light onto this before I lost my sanity

Hello list,
I am in a need of GUID generator but it seems that PHP doesn't have this as
a built-in feature.
I looked at http://pear.php.net <http://pear.php.net/> and
http://pecl.php.net <http://pecl.php.net/> but found nothing suitable
there.
I really need "true" unique identifiers - md5() hash is not OK because of
the "birthday paradox".
Can anyone recommend a way for solving this trouble?
Have a great day,

uniqid() ?
Bearing in mind of course that no unique ID generator can ever be 100%
unique unless it keeps a record of previously generated IDs. So you
may wish to add this check.
Cheers,
Rich

I use:
$unique_id = sha1( uniqid( mt_rand(), true ) );
which should be very unique and suitable for most purposes.

I really need millions of unique IDs - hashing is not suitable for this task
(I think so) :-(. Any more ideas?
Is there a PHP extension or an external library for generating GUIDs?

While not ideal, you could do a select on a db. MS SQL and MySQL both have
functions to generate unique id's and I imagine the other databases do as
well. While running a "SELECT uuid()" and hitting the database for each
one of these things is annoying, it is one possible pseudo-solution.

hi,
i want to create a "shop server" application. the shop client interface
will be in flash (communication with php over xml, soap or amfphp), the
administration interface will be html. most likely it will probably
be a
long-running application that will be extended in several steps, so we
need a solid foundation. we also need to get started quickly (who
doesn't), otherwise i would consider starting from scratch.
i have already looked around quite a lot for a nicely adaptable
shop/ecommerce implementation, but haven't been very successful so far.
everything i found was conceived in php4 times, where OO wasn't as
wide-spread in the php community as it is today. some of the packages
are poorly documented (both in-code and separate documentation),
have an
inconsistent coding style, are dead, are copies of oscommerce with a
worse interface, ...
feature-wise the best i found was xtcommerce (oscommerce fork)
admin interface wise: zencart (oscommerce fork)
code-wise: randshop
non of them use php5's features, though, none are written
object-oriented.
i have no info on the performance of these shops, although that
shouldn't be a prob as long as it's not desastrous (to some extend, you
can always scale hardware-wise).
so i am looking for a cleanly layered application where i could swap
out
the presentation layer. and all important shop data (products, product
categories, cart, etc.) should be represented as objects, so i could
extend them to implement required customizations.
it would be a big plus if the admin interface was well thought-out.
we need quite some features like multiple languages, multiple
categories, discounts on certain products, payment provider
integration,
customer newsletters, possibly administration of several slightly
different shops in one installation, etc.
is there such an application or am i stuck with oscommerce and its
forks?
i don't need it to be feature complete, as long as there is a way to
adapt the code without hacking the whole thing (and loosing the
possibility of upgrading).
as long as the code was open, i would be happy to pay a certain amount
for the application.
anyone?

It appears you are learning php.
I suggest that you will find it very rewarding to learn the array functions. I certainly did when I first started work
with php.
There is an array function that does exactly what you want.

Thanks for the detailed explanation.
I should have expanded further on my design goals though. I initiated my
examination of this problem when I tried to generate my "on-the-fly" images
with a class method like:
// on_the_fly.php
<script language="php">
class on_the_fly {
function on_the_fly() {
}
function a_graphic() {
$image = imagecreatefrompng("my_graphic.png");
imagepng($image);
}
}
</script>
then call the method as needed as in:
// my_page.php
<html>
<head>
<title>Untitled Document</title>
</head>
<body>
<script language="php">
include ('on_the_fly.php');
$otf_graphic = new on_the_fly();
echo "<img src=$otf_graphic->a_graphic()">;
</script>
</body>
</html>
This resulted in a page filled with random characters.
So I interpret from your response that I'm still unable to reference "<img
src=$otf_graphic->a_graphic()"> and MUST create my on-the-fly graphic in a
*.php file or *.png as you suggest.
Thanks

This before or after you switched to Apache?...
[/snip]
Before...the switch to Apache solved many, many problems.
[snip - for informational purposes]
Can you surf to a static page?
Can you surf to a static page in the same directory as the PHP page?
PHP CGI or Service/Module?
Anything in the log files?
Do all browsers say 404, or is that just the badly-broken MS IE
generalized message?
[/snip]
I could surf to static pages, including ones in the PHP directory. PHP was
running as ISAPI. The log files showed 404 errors regardless of browser. The
PHP was working fine until I rebooted the server, which was done to see if I
could solve the extensions problem. With Apache installed the only thing I
have to worry about will be some PERL stuff and I will probably install
Apache::ASP to handle some legacy stuff until I can convert it to PHP.

I'm afraid not. You can hack recursion in Perl with the (??{ })
postponed expression construct. But PCRE doesn't support it.
Without recursion, the best you can do is decide on a reasonable depth
of nested comments and hardcode that.

I'm not sure exactly what you mean here. It's true that comments don't
affect how mail gets delivered, but they're very definitely part of
the address and may well have a meaning to the recipient that you
can't predict. They could be using it for anti-spam or to disinguish
between users of a mailbox or... well, anything really.
Which is the reason that RFC-2821 recommends that they be passed to
the recipient unchanged.

I had a quick look through my email last night and found 14 different
email validation regular expressions posted to this list in the last
few months. All of them would falsely reject valid addresses even
without taking comments into account. 6 of them wouldn't even allow
"judy.o'[EMAIL PROTECTED]" and another 3 would reject mail from the
entire .museum TLD.
What that would indicate to me, is that many people can't even
recognise what a "good enough" regular expression looks like.

Possibly because those whose email addresses it rejected couldn't
contact you to complain? :-)
Actually, I have very little problem with your regexp - I'd like it to
handle domain literals, as they can be useful in communicating with
people with broken DNS. But that's about it.

Just in case anyone's inspired to read through the specs; It's
RFC-2822 these days. RFC-822 is obsolete.

Hi,
Got round the problem by doing this instead:
$param = array(
'country1' => 'uk',
'country2' => 'usa'
);
$wsdl="http://www.xmethods.net/sd/2001/CurrencyExchangeService.wsdl";;
$curr_client = new nusoapclient($wsdl, 'wsdl');
$rate = $curr_client->call('getRate' ,$param);
The ends justified the means, though I am still using SimpleXML to parse my
Copyright Clearance Center processes.
Cheers
George

I just found this is known bug and was already fixed in CVS.

Howdy all,
I am trying a new technique, for me, when processing a form. The form is
filled out and submitted, during processing it is determined that there is
an error with the posted data...such as a blank or mismatched password,
I want to return the form with the data filled out using curl....as a test I
did this....
/* curl post test */
$post_data['username'] = $_POST['username'];
$post_data['password'] = $_POST['password'];
$url = "http://TEST20051010/FMSRegister.php";;
/* assemble POST data in string */
$pd="";
foreach ($post_data as $k=>$v){
$pd.= "$k=".$v."&";
}
$post_data=substr($pd,0,-1);
$ch = curl_init();
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data);
curl_setopt($ch, CURLOPT_URL, $url);
curl_exec($ch);
curl_close($ch);
Now, this works OK...save for one little problem that I cannot seem to
figure out. The URL now reads
http://TEST20051010/NameOfProcessingScript.php instead of
FMSRegister.php.
I am searching the curl options http://www.php.net/curl_setopt but have not
found what I am looking for. Can someone clue me in?
Thanks!

If, for some weird reason, you want to allow the user (authenticated,
logged in, trusted) to print to a networked computer on the WEB
SERVER, then your best bet is probably to figure out how to print that
PDF from MS-DOS and then to use http://php.net/exec to print it, I
would guess...
It's from a cli PHP install on a local machine :-)
You might be able to use PHP to open up a COM object to convince
Adobe/Windows/whatever to print...
COM makes me want to cry ;-) At the moment I'm trying to convince
OpenOffiice it wants to play with PHP and COM.
I have tried to exec print on the windows box but that just hung.
If it was a Un*x server, you'd just send the document to lpr or CUPS
or something, and be done with it, probably in a half-hour of work,
even allowing for a protracted battle with file/exec permissions.
I'm not sure I could just fire a PDF at lpr, but no doubt it would be
much easier under Unix :-)

Two (and a half) things:
1. Even though DOS/Windows machines don't have, specifically, /dev/printer or
/dev/lpr or whatever the *nix specific is, it does have a LPTx: device
According to the page listed below, it may be possible to do:
copy /b filename LPTx
The /b indicates it's a binary file. How it'd handle PDF fonts and such, I'm
not sure, but I know that some printers can decode PDF's internally so that'd
work out great.
2. Second point... If all you need is a simple print function and you have
exec() privs, why not try to find a DOS based printing solution. The copy
command above was mentioned on this page:
http://www.lerup.com/printfile/
It says it works with Windows 3.1 to XP. And it even works with command line
options:
"PrintFile also works well with command line (DOS) programs. It has several
command line options and can read data from command line standard input, e.g. a
command line pipe. A command like:
dir | prfile32"
So I guess it sets up it's own print device that you can pipe to.
And finally... the half a point. All of this may not be necessary because you
can configure Windows printers to support DOS (although I havn't done this in
ages, I assume you still can in XP) so in theory the normal DOS "print" command
would pipe through Windows drivers and print handling to the printer of choice.
So in general, there's probably zero need to use COM to print. One of these
options should pipe the file through Windows which in turn, could possibly send
it through the proper printing method. If not, you might be able to look in
your registry and find the right-click "Print..." option and see if it's
something you can execute from command line.
Ok, I know this email's too long already, but I know someone's going to say
"How do you do that?" So here's the 50 cent tour:
1. Pull up "regedit"
2. Search for the file extension ".pdf"
3. Make note of the "(Default)" value, in this case "AcroExch.Document" (I
think this is specific to having the full Acrobat installed)
3. Below the area where all the file extensions are in HKEY_CLASSES_ROOT there
are the actual named app section (that way, ".gif" and ".jpg" can both point to
Photoshop.document" or something.. get it?) So search for "AcroExch.Document"
in this case
4. Expand that tree and look for "shell". These are all the things that show up
on your right-click menu. In this case, we have a "print" section. Under each
of these entries, there should be (but sometimes not) a "command" branch. This
is what's run when you select that option from the right-click menu. And
voila! We find that the command to use Acrobat to print (which can be executed
from command line on a Windows machine) is:
"C:\Program Files\Adobe\Acrobat 5.0\Acrobat\Acrobat.exe" /p /h "%1"
Substituting the %1 for the filename.
Using that command line in a php exec() call should exactly simulate selecting
right-click PRINT on a PDF file.
Crossposting this to PHP-Win for their benefit too since this is more Windows
related than PHP General.
I see lots of ways to potentially solve this problem without using COM.
I loved messing with COM (with or without PHP) for a while, but it's not a
great general solution to things unless you absolutely HAVE to control the app
(which is very cool and slick sometimes, but not for something as simple as
printing).
Hope this gives you some new avenues to persue. Best of luck!

Convert the .doc to a .txt document before opening it with PHP.
There are external tools available to do this but I won't do the
searching for you ;-)

thanks, Richard :)
The simplest solution is usually the best
As you suggested, I used php to created a 'log in' movie which upon
authentication loads the playlist of movies
Also, as you suggested, I think I'll create a session id with a
master password, can see everything, and a 'movie specific' password

How do you *KNOW* it originated from ITSELF?
Can't I just fake it out by copying the URL you are using?
This request was sent from OUTSIDE the server. The main script,
makeMoviePlaylist.php, realizes the this request did not originate
from itself on the server
Again, how you do *KNOW* that to be true?
What's the big picture again?
They need to login to see the movies, right?
Or is it something else?
If just need login, use http://php.net/session_start and friends as I
just posted.
If it's something else, session_start() may not help.

Hi guys.
I've created a small newsletter application and the content of the
newsletter is stored in a DB (the HTML).
However once the newsletter is complete and the user clicks a button I
want the newsletter/html file to be created on the server. How do I go
about this?
I assume that I will use fwrite() to add the HTML to the file, I need to
know how to actually create the file before adding the content to it.
thanks in advance.
