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 adminfirst.com for the first domain and
adminsecond.com 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
adminfirst.com and adminsecond.com 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 adminsecond.com (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.

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.

Hi,

just take a look at this function:

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
Chris

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'gradyexample.com" 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

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

http://bugs.php.net/bug.php?id=34450&edit=2

thanks to all!

attached mail follows:

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!

 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.

Dave.

attached mail follows:

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

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.
