To get an array full of the file names you want:
$interestingFiles = array();
$dir = opendir( "/path/to/directory" ) or die( "Could not open dir" );
while( $dirEntry = readdir( $dir ) ){
if( ereg( "full", $dirEntry) ){
array_push( $interestingFiles, $dirEntry );
}
}
I'll leave it up to you to sort $interestingFiles by the date in the
element values, since I don't recognize a date in your file-naming
convention.

It'd be easier to sort if you changed your date format a bit ... what you
have is rather difficult to work with, unless you take the string apart.
(i.e. - How is '7102002' not greater than '6122002'?)
For simplicity & ease, I work with date strings formatted as "MMDD".
If your files were named "something-full-MMDD", you could get a sorted
array of your files easily.
$interestingFiles = array();
$dir = opendir( "/path/to/directory" ) or die( "Could not open dir" );
while( $dirEntry = readdir( $dir ) ){
if( ereg( "full-([0-9]{8})", $dirEntry, $MATCH ) ){
$interestingFiles[$MATCH[1]] = $dirEntry;
}
}
ksort( $interestingFiles );

If you mean that $_POST['vars'] is an array of numbers:
$total = 0;
foreach( $_POST['vars'] as $number ){
$total += $number;
}
If you mean that all vars in the POST data are numbers you want to add:
$total = 0;
foreach( $_POST as $number ){
$total += $number;

Ah!, I think I understand better now. You want to add num1, num2, num3,
... numN, which are inputs from the second form in your sequence. Gotcha.
If you name /all/ the form elements as "nums[]" instead of individually as
"num${current}", the numbers put into the form will all be accessible in
one array to the PHP script that does the adding. Then you can just loop
over the array of numbers.
In your second form, change this:
""
To this:
"
Then in the script that adds the numbers:
$total = 0;
foreach( $_POST['nums'] as $number ){
$total += $number;
}
Hopefully I understood your problem this time! Let me know if I missed
again.

Oh my! That's not going to work, because
"make_calendar.php3?month=$month&year=$year" is not a file in your
filesystem. I'd start making suggestions on what you can do to achieve

I can man an uncomfortable assumption, though: You mean to generate

The most likely scenario is that common.php is being processed by the web
server & PHP before being included into your code. This would be causing
a second HTTP request from your web server to your web server for the
included code ... there are no cookies on the HTTP request for the
included code, /and/ the variables available to the parent are not
available to the included code. You effectivly get the output of
common.php, not included code.
Try this:
- copy common.php to common.inc (or some other extension that your web
server is not configured to hand off to be parsed by PHP).
- in the parent code, include() the common.inc URL instead of the
common.php URL.
Let us know if that helps or not.

You've already demonstrated that you know included code inherits the parent's variables at the scope where require() is called ... so I'll leave it up to you to determine whether or not the "?variable=1" is necessary.

Give your submit buttons names and values, then you can check the button
element's value as submitted and made available in $_POST.
i.e. -
In your HTML (notice the button /names/ are the same) :
And in your PHP:
if( $_POST['submitButton'] == "form1" ){
// do something for form 1;
} elseif( $_POST['submitButton'] == "form2" ){
// do something for form 2;
} else {
// some tardnugget is playing games with your form ;)
}
There are several variations on this ... hope this one helps.

It's /real/ hard to tell when you don't give any context or otherwise
explain what it is you want to achieve. Since the code in fact executes
correctly, we can only explain what's going on in your code, not why it
doesn't work for your needs ...
You while() loop runs through a mysql result set in its entirety the
first time through the foreach() loop and leaves the result pointer at the
end of the result set. All subsequent runs of the while() loop will start
fetching results from the end of $show_names ... and get /nothing/.
If you want to use all the results out of $show_names again, you have to
reset the result pointer to the beginning of $show_names. Use
mysql_data_seek(). http://php.net/mysql_data_seek, and see below.

in your php.ini. If you have magic_quotes_runtime = On, then it will also
unescape double-quotes (and backslashes and NULLs).

foreach() would work for you ...
foreach( $dirs as $dirName => $indexName ){
$indexPath = "${dirName}/${indexName}";
$fh = fopen( $indexPath, "r" );

Say that the paragraph you gave is a string in a variable, $TEXT ...
$allowedChars = "/:@\w.#~?%+=&!-";
preg_match_all(
"{\bhttp:[$allowedChars]+?(?=[$.:?\-]*[^$allowedChars]|$)}x",
$TEXT,
$URLS
);
foreach( $URLS[0] as $link ){
print( "${link}\n" );
}
That should get ya started. Read up on regular expressions, and the
regexp functions in PHP to make heads & tails out of the code, other than
"it works." (So far it works well for my intentionally limited purposes
... I wouldn't be surprised that someone finds a case where my code
breaks, or someone can/does easily extend the regexp to grok more stuff.)

but you failed to address the caching of images in any of your code or
setup. The cache headers on the view.php script have /no/ affect on
anything but view.php. You're fighting the communication betweneen the
browser and the web server, so configure one or the other to play nicely.
- Disable caching in your browser.
- Configure your web server to include cache-control & expires headers on
all pertinent image requests. (For example, see mod_expires for Apache:
http://httpd.apache.org/docs/mod/mod_expires.html)
In lieu of those, change the way you handle uploads.
Instead of using the exact filename of the uploaded file, rename the file
slightly, to include a timestamp or some other changing identifier each
time the file is uploaded. For exampple, when myImage.jpg is uploaded,
save it as myImage-001.jpg the first time, myImage-002.jpg the second
time.

I consider FTP a security risk, period. (There /are/ ways to run an FTP server securely, but I won't assume everyone, or even anyone, knows this.) The possibility of having plain-text authentication flying around ... security risk. This is probably the perspective of your hosting company. You may want to only access a server which provides anonymous FTP. You might not use the same username and password to the FTP server that you use on the hosting server. You might only be accessing a server on a trusted network. But you're just one user. From a sysadmin perspective, that's a lot of assumptions made about all the other users who could potentially use those FTP functions and not take the precautions you took. (Not to mention, that it's a bit rude to expose someone's FTP server to compromise just because the security issue doesn't affect the hosting server. Plain-text authentication, such that FTP and Telnet use, are the bane of sysadmin existence ... usernames and passwords are sniffed too easily.) That said ... FTP is a protocol; there's nothing stopping you from opening a socket and talking FTP back & forth across it (unless your host has disabled fsockopen() too). If you know the protocol, you probably know how and why to avoid its security concerns.

That's precisely NOT what the hosting provider said (at least it's not what my appreciation for running a secured web host led me to believe they said). I don't expect you to be a security expert, but think with me through a very common scenario sysadmins must account for. I'll use the word "you" in a general sense: You access an FTP server with a user name and a password to retrieve a file via PHP FTP. The user name and password is the same that grants you access to your hosting providers server. (People do this v.frequently. Most people have trouble remembering one username/password, so they make the dangerous choice to use one username/password over and over again.) A malicious individual sniffs your username and password while you transfer a file via FTP from to you hosting provider. Once the individual has his way with your FTP site using your credentials, (s)he does the obvious next step ... attempts to use the same credentials to gain access to your hosting providers server. Make sense? That didn't take much time, effort, or thought to get the hosting provider compromised. And note that it had nothing to do with PHP. It has everything to do with FTP itself. Like I said, originally, you and/or your customer might take precautions against something like this, but there's no way a responsible sysadmin can assume or be assured that every user on a system will do the same. The hosting provider isn't trying to protect itself from malicious people attacking some vulnerability in PHP's FTP extensions. The webhost is trying to protect itself from it's own users who might code somthing using an insecure protocol which might allow malicious people easily gain access credentials to its servers, or othewise allow abuse of a server's resources. PHP's FTP extenstions aren't a security risk. The security risk is what users can do with FTP. At the /risk/ of introducing more reasons for the webhost to disallow the FTP extensions, forward them this thread and ask if these are indeed their reasons. > I am not trying to start a debate on whether or not people should send > passwords and userids over plain text. Yes, that is a security risk. > My concern is that this webhost is telling my customer that PHP FTP > itself is a security risk when it does nothing more than act like > ws-ftp.

Modern FTP servers support virtual users and chroot so the > risk of server compromise is minimised. Not so. Nevermind gaining access to the hosting server via FTP. With stolen credentials, one might log into the server via SSH, or gain access to other services on the box with the stolen credentials. It doesn't matter what modern service you have running ... once you've stolen the keys, you're in, and you can do /something/ you're not supposed to do. I've seen chrooted home directories in exactly one place. You'll almost never find them in a shared hosting environment. Most likely, there are quotas. Even so, the risk of having unauthorized users on your server(s) is not acceptable under any circumstances, especially through one avenue you know you can shut down. With the quotas in todays shared hosting offerings, there's enough space to distribute/run/launch a myriad of malicious software, or simply replace the account owner's content with warez for a short time. The risks range from a minor pain in the ass to becoming a platform for launching [D]DoS attacks, worms, or viruses. On the Internet, risk is risk, big or small, and none if good.

The original question dealt with making an FTP connection to an outside FTP site from a web host. The FTP server and the web server aren't run by the same people/company. The web hosting provider objected to allowing outgoing FTP connections. Nowhere in this thread is the opinion of the owner of the FTP site about incoming or outgoing FTP connections. Also, nowhere in this thread is mentioned how files are uploaded to the web host. That's left to our imaginations, I guess. If you assume the users use FTP for uploads, then you have to assume the hosting company is a band of hypocrites. If you assume the users use SFTP or SCP for uploads, then you have to assume the hosting company's objection to outgoing FTP is actually addressing a security concern. I erred to this side so as not not unduely ridicule anyone, and to share some pertinent insight from my experiences with running a secure shared host. Also, the manager-speak in the original message included verbiage from the hosting company stating that the company had already been burned by a similar circumstance. They apparently learned from it and are being somewhat smart about what they enable and disable. I gave them the benefit of the doubt on whether they were really addressing a security concern ... and I agree that there is a security concern to address. ~Chris -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Consider this (Warning: I haven't tried this, yet): Write your session handling functions and put them in a file ... say, /var/www/server/custom_session.php. Call session_set_save_handler() with your function names as arguments in that file. (Good explanations here: http://www.php.net/manual/en/function.session-set-save-handler.php) In your php.ini file, set: session.save_handler = user auto_prepend_file = /var/www/server/custom_session.php This will cause PHP to use your custom session handler system-wide, while remaining transparent to your users, I believe. (If anyone knows this to be not the case, let me know.) Caveats: You'd have to make sure you custom handler function names are unique enough so as to not conflict with functions names your users can create. I'm not sure what will happen if your users call session_set_save_handeler() again, but with their own functions as handlers.

Your code works as you'd expect ... on my mod_php 4.2.2 & Apache 1.3.26
setup. It's amazing though, because implode() is used incorrectly.

The above line:
I'm assuming you want to collapse $recordsarray into a sting, with the
elements of $recordsarray separated by a null char. Well, you told
implode() to collapse a null char into a string with the elements of null
char separated by $recordsarray ... inverted the arguments to implode().
I have no idea why an error isn't raised instead of kind-of working, but
anywho
Try switching the arguments around in the call to implode(), to:
$lines = implode('',$recordsarray);
http://www.php.net/manual/en/function.implode.php
If that doesn't correct the problem you're experiencing, let us know.
I have other ideas for you, but they may not be necessary if that solves
it.

Actually, it's literally printing "[0]" after it prints "Array". PHP is
detecting that $manilist (not $manilist[0]) is an array (for which it
prints "Array"), then you get a literal "[0]" afterwards because you put
it all within quotes.
If you print this way, you'll get what you want:

So, while you may fully intend to stash passwords access to only your application, you may actually be storing passwords to people's online banks, work logons, pr0n sites, etc. You can save yourself a lot of time in the future by taking a little time now to make sure that plain-text passwords are not retrievable from your application/database. If your database server were to be compromised, you can rest assured that you didn't leak any passwords. Otherwise, you'll have to really worry that somebody didn't walk away with a list of names, usernames and passwords that could be used elsewhere. > The reason I ask is because I'm trying to implement a "forgot password" > feature on a membership site.

While this is true, what I've found in practice is that this rarely happens (actually hasn't happend yet, for my sites ... knock on wood). If you find that this becomes a problem, some logic around how often, and by what method passwords can be changed may help alleviate the problem. g.luck, ~Chris -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Of course.

You've done two things with this statement. (1) Got all the keys from
$test, then (2) printed out the keys in "human readable" format.
print_r() is printing information about the array which was returned from
the call to array_keys().
Examine the output from "print_r($test)" and check the documentation for
print_r() & array_keys() to get a glimpse into what might be the source
of what's got you a bit confused.

You can access array indicies by number for non-associative arrays:
$test = array( "A", "B", "C", "D" );
OR associative arrays that use numbers for keys:
$test = array( 0 => "A", 1 => "B", 3 => "C", 4 => "D" );
echo( $test[2] ); ... will work for either of those,
but the indicies of your original $test:
> $test = array ( 'a' => 'A', 'b' => 'B', 'c' => 'C');
have to accessed with the appropriate key.

... because you've created an array ($ID_arr) with an array as the first
value (the result of the call to explode()). Take the brackets off
$ID_arr, and you'll get what you want. You don't want your array in an
array ... you just want an array.
$ID_arr = explode(',', $pictures);
If you really wanted your array in the array, then loop over $ID_arr[0].

Re: [PHP] problems with cookies
A couple problems may exist:
1) If you're trying to do this all in the same script, it's not going to
work. You can't set a cookie and use it (with the value you've just
set) in the same script (in the same request). You can only use cookies
that have been sent back to your script from the browser. If you
require the use of a cookie value you're trying to set, use your local
variable's value, instead of trying to get the cookie.
2) I'm pretty sure there is not timeset() function in php.
> setcookie("cookiename1","$domin","timeset()+1800");
And you've used it as a quoted string ... set a very funky, if not very
invalid, expiry time, and hence didn't set the cookie at all. Try this
instead: setcookie( "cookiename1", $domin, time()+1800 );
On a different request, you can retrieve $_COOKIE['cookiename1']

header() is a PHP function. You're calling it with an invalid arguement.

Try calling header_row(), instead of header(), with your array argument,
since it seems that you already have the proper function defined.

Dude, you don't change to the root user ... you'll get yourself owned that
way. Change the permissions on the directory to allow the web server's

Re: [PHP] Re: submitting a form to multiple places!
Your problem is tough to understand. Submitting form data to multiple places isn't normal, and your need to do so wasn't clear to me. When you have total control of your environment, the need to re-submit submitted data is superfluous. If you must have a PHP script that handles submitted data and also submits it to someplace else, check out the CURL functions. You can create any kind of HTTP transaction you like with CURL in a PHP script, including a form submission. http://www.php.net/manual/en/ref.curl.php g.luck, ~Chris On Tue, 1 Oct 2002, Henry wrote: > No takers? > > Is this such a difficult problem? > > Please help. > > Henry > > "Henry" <[EMAIL PROTECTED]> wrote in message > [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... > > Hi All, > > > > I have a problem that I hope you can help me with. > > > > I'm using a third party shopping cart solution which is quite frankly > naff. > > They bundle some autoresponders with it.

Re: [PHP] Just cant figure out how this could be happening...
"SELECT CURDATE() - 14" ... this isn't doing what you think it's doing.
The CURDATE() function returns a string like "2002-10-03".
Subtracting 14 from that gets you "20020989" as a result from MySQL.
Pretty useless, right? If that ever worked for you, it was a total
coincidence.
Try this instead:
SELECT DATE_SUB( CURDATE(), INTERVAL 14 DAY )
That will get you the date from 14 days ago.
See the MySQL manual for descriptions of the functions.
I'm sure that the MySQL site has references to MySQL mailing lists too, to
help with MySQL questions.

It doesn't work at all like you want it to. I assume you've already put
this script up on a web server to test, so watch this:
After this line:
$$key = $val;
Insert this line for debugging:
echo $key . " --> " . $val . "\n";
Then visit the script:
scriptname.php?foo=2&2=1
You've created something far worse than register globals.
Someone already posted a decent solution, something like this:
foreach( $get_allow as $get_key => $get_val ){
if( isset( $_GET[$get_val] ) ){
${$get_val} = $_GET[$get_val];
echo $get_val . " --> " . $_GET[$get_val] . "\n";

[PHP] ill sprintf() behavior w/ HEX type
Using PHP/4.2.2 & Apache/1.3.26 on Linux 2.4.17 I'm trying to format a HEX value into an 8-byte string, that is zero-padded to the left, using sprintf(). Simple enough. $sprintf( "%08x", "fa23d" ); This should return "000fa23d". But it returns "".

Re: [PHP] Question about using XSLT_Process?
You just need the XML and/or XSL as a string. xmldoc() is creating a DOM
object, which xslt_process() can't use.
In you example that does not work properly, change this:
$xsl = xmldoc(implode("",file("test.xsl")));
$xml = xmldoc(implode("",file("test.xml")));
to not use xmldoc(), like this:
$xsl = implode("",file("test.xsl"));
$xml = implode("",file("test.xml"));
xslt_process() should be happy with the strings in the arguments array.

The result will be that $var1 == "foo" and $var2 == "bar". You can mix it up too ... if you want the function to return a value (say, true or false) AND modify arguments, modify only a subset of the arguments, etc. (see http://www.php.net/manual/en/functions.arguments.php) g.luck, ~Chris /"\ \ / Microsoft Security Specialist: X The moron in Oxymoron. / \ http://www.thebackrow.net -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] returning more than 1 value from function
Sorry ... busy morning ... I misplaced the & for the reference. They
should be on the arguments on the function definiton, not the function
call.
Sorry if I caused any confusion.

Does the php.ini affect both? Specifically script times? Check the output of phpinfo() for each and see. You're looking for the line that's tagged "Configuration File (php.ini) Path". Usually there are different files for the module and the cgi. (i.e. - the packages from Debian Linux distribution(s) puts separate php.ini files into /etc/php4/apache and /etc/php4/cgi.) g.luck, ~Chris /"\ \ / Microsoft Security Specialist: X The moron in Oxymoron. / \ http://www.thebackrow.net -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

you probably want an "or" before that die().

Re: [PHP] Code Troubles
if( $db ){
@mysql_select_db($db) or die("The site database is unavailable.");
}
To debug, use print( mysql_error ) instead of die to figure out what's
going on. It's not that far of a leap in logic.

Re: [PHP] HTML form element
Name your select element "majors[]" and when the form is submitted, your form handler will get an array, not a scalar, called $majors.
