I appreciate all the input that I've gotten from all the list members.
I think I've come to the conclusion that leaves me exactly where I was
prior to asking the question. The determination to split inline code
from included files is left strictly up to the programmer him/herself,
and there is no rule of thumb to any of this, except in cases where
painfully obvious.
I thank you all for your time. I'll continue to monitor this list for
many months to come.

store them in a previously defined array (for example private $_vars;

another way to control access:
class test {
private function __construct() {}
function __get($var, $val)
{
$r = (isset($this-$var))

function __set($var, $val)

[PHP] Fatal Error Handling
Hi,
I have a set of functions which are potentially dangerous in terms of
memory hogging, and need to protect from memory overflow - this is I
want to detect when the memory overflow occurs.
The manual says that eval() will return false on a fatal error, so I
thought I could do something like the following, where it would produce
a O for each itteration, and when it failed (memory overflow) it would
continue and echo the last line. What I get however is this attached to
the end.
Any advice would be gratefully recieved (and perhaps, the documentation
on eval updating if it can not catch all fatal errors)
#! /usr/bin/php
?php
$y = 0;
$str = ;
$code = '$str .= $str . .; return true;';
$x = TRUE;
while($x != FALSE){
$x = eval($code);
echo O;
$y ++;
}
echo \n $y it's \n\n . $str;
?
run:
$ ./intellirun2.php

Re: [PHP] Re: stream_set_timeout() stream_get_meta_data() etc...
Quoting Al [EMAIL PROTECTED]:
Darn, I left out an important function, the fread(). Code snip should be:
$fp= fopen(http://www.anything.com/foo.html, 'rb');
if(!fp) {do something different}
stream_set_timeout($fp, 2);
$contents= fread($fp, 20);
$status= stream_get_meta_data($fp);
if($status[timed_out] {do something};
It appears to me there is a basic logic problem. The script must get
past the fread() function before it gets to the stream_get_meta_data($fp).
But, it hangs up on fread() and the script times out.
Set the stream to non-blocking mode (stream_set_blocking). Now all
read functions will return instantly, regardless if any data came
through. You can test whether you got back anything by checking the
returned data. If you now read from the non-blocked stream in a cycle,
you will have no dead times and you will always retain control.
Only now can you rely on comparing time() with a control value set
before entering the cycle and decide to abort if a number of seconds
has passed.
stream_set_timeout() will be pretty much superfluous at this point
and may even hinder your reading from the stream.
Important tip: in a non-blocking cycle you MUST have an usleep()
somewhere. Otherwise that cycle will consume 100% CPU while it
runs. An usleep(1000) will suffice, adjust as needed.

Is their any way to get PHP to clean up any remnants of any variables that might be in memory after a script is run? IE, is their a way to get PHP to overwrite the memory used by variables at the termination of a script? I wasn't worried about this before but I think the paranoia regarding CCN's on this site has gotten to me... Better safe than sorry! I don't think there is any way to do this... There may be an external library one could compile into PHP, and maybe one could then write their script do scrub their data... Even so, what about $_POST and $_GET and whatever temporary C strings/structs that PHP uses internally to store data. You may want to look at the Hardened PHP site, and see what they've got -- If anybody has done this, they'd be the ones. You could also ask them what they think of the idea from a feasibility stand-point and how useful it would be. I suspect that you'd have to do it at a much lower level than your PHP script, though, to be useful. If I can manage to read your script variables, I can also manage to read the PHP source code's C variables, so scrubbing just the $cc in PHP won't be enough. You'd also need to consider page faults and swap space while you're at it. Scrubbing your RAM does no good at all if the data got swapped to disk and the Bad Guy can read that. There's a low-level C function to force memory to *NOT* get swapped... I forget its name, but run cdrecord as non-root and you'll run into right quick-like, as I did the other night :-) I think, perhaps, though, that this is all going beyond what would be considered expected practice at this juncture in history. As I said earlier, anybody skilled enough to fish in your RAM to get credit card numbers, is probably skilled enough to get them much easier than that. That doesn't mean this won't change tomorrow, if PHP provides an interface to that low-level C function for your variables, or the Hardened PHP guys decided to implement this sort of stuff. Perhaps running Hardened PHP would be a good step to consider for a server handling CC numbers. Even if it's not feasible/needed to scrub RAM today, I'm guessing they'd be the first to implement it if it was feasible/needed. YMMV IANAL NAIAA Amazon store Credit Card Number in their databases.

[PHP] Multi-Page Forms
I have a form which is too long to be useful displayed on one page. I have it broken up into 7 sections. All 7 are generated by the same PHP source file, from data in a database. When the user updates a section they can submit it and go to the next section, or submit it and finish (return to a higher-level page). There is also a navigation form at the top that lets them jump from any section to any other, and uses JavaScript to prompt if they try to jump without having saved changes they made to the page. All of this is working fine. What's bothering me here is that when the user is done editing the data I use their input to regenerate a style sheet (the form allows them to customize the appearance of a web page for their customers). That's expensive -- relatively speaking -- in server load so I'd rather do it only once, when they're really done.

Re: [PHP] phpBB alternatives?
Yes, please read that page again. It had nothing to do with the phpBB software itself, but with the AWstats that run on their server. The vulnerabilities that phpBB a few months back had were quickly patched. The phpBB community is huge and offer fantastic support. Other alternatives include vBulletin or YaBB. Too bad the same reaction that hosting providers are have toward phpBB don't take place in the real world when a Microsoft product vulnerability is exploited. From the recent update at phpbb.com: ... It is actually quite fustrating at present that some hosting providers are asking or forcing their customers to remove installs of phpBB 2.0.11 due to the loss of phpbb.com. As I say above, our best available information right now is that phpBB was not to blame. ... Equally it's annoying to see some people posting the same old highlighting exploit claiming their 2.0.11 board was hacked via it. Again unless my team and indeed our other teams, heck large sections of our community, are all lying to me that vulnerability was fixed in 2.0.11. Sites running .11 and claiming (or thier hosts claiming) to have been attacked using it should take a close look at other applications they have installed. phpBB is not alone in being exploited, all the major boards can be if you don't update as new releases are made. Equally users should ensure the relevant highlighting fix is indeed present. Over the years we've dealt with thousands of users who say they've patched something (be it an exploit or bug) but upon examination we've discovered the problem code is still there. Equally hosts should look at their own systems. Are you running awstats if so have you updated? Do you regularly update your OS and particularly the kernel (if appropriate) as fixes are released? Are your users running old versions of other PHP/Perl/etc. software? Have you set appropriate permissions on key folders such as /tmp and /var/tmp? Is your webserver running with as few permissions as possible? Just because we overlooked something doesn't mean you should! ...

Re: [PHP] Re: Storing CCN's Again...
[EMAIL PROTECTED] wrote: Amazon store Credit Card Number in their databases. Are we saying that someone could hack into their database server and steal the numbers? YES! Wasn't PayPal widely publicized as a victim of such an event? Why would you think Amazon would be any better/safer? No system is unbeatable. So somebody *could* break in. You can be damn sure they work really hard to avoid that. Or have Amazon gone far enough to protect their data? How far is far enough? I supose they use a similar tactic as i have, and have a two way encryption method. I suppose they do a LOT more than that. They might, just as an example, have a network setup like this: Seg 1Seg 2 Seg 3 Internet --- Public Servers --- CC Processing Servers --- CC Storage Servers Where Seg 1 and Seg 2 and Seg 3 are all on: Completely different sub-networks Completely different network cards Completely different routers, hubs, switches Completely different color-coded network cables . . . And, of course, they use two-way encryption of the data that *IS* on the CC Servers, so while the secret decoder ring is on the CC Processing Server, you'd have to break into CC Processing, get the ring, break into CC Storage, and then apply the ring from CC Processing to the data in CC Storage. Is this starting to sound like an Adventure Game or what? They then severely restrict the source code and network access that can work with Seg 3, with an EXTREMELY limited API, internal documented, security audited, clean-room access, armed guards on all hardware setup, etc Instead of breaking into CC Storage with your secret decoder ring from CC Processing, you can maybe find a flaw in the API of Seg 3, and sniff out encrypted data to apply the ring, or even catch it after they decrypted it. The point is, you have to work much harder at it because of the segmented architecture. By adding an additional layer between the CC Processing and the CC Storage, they reduce risk significantly. All the CC machines (Processing and Storage) are in the armed guard locked storage room for physical access to be severely curtailed. Duh. But the CC Storage machines have an additional layer of software/network blocks with severely limited software/network access to the CC Storage area. I'm not claiming they *DO* have this, but I'll bet whatever they do have, it's at least that complicated, if not more so. Or, even more likely, Amazon doesn't store the number! They let the BANK that provides their CC processing services store the numbers. So then the BANK has this kind of setup. Whatever. This is just a description of what was explained to me on this very same list several years ago as *ONE* industry-standard way to store CC Numbers for later retrieval. I'm not an expert, and may easily have left out some (okay a lot) of crucial details. If you're storing CC Numbers with *JUST* the 2-way encryption, maybe you're doing it wrong. I dunno for sure, but *I* think so. Go hire a professional security audit and find out.

I have a set of functions which are potentially dangerous in terms of
memory hogging, and need to protect from memory overflow - this is I
want to detect when the memory overflow occurs.
The manual says that eval() will return false on a fatal error,
snip snip
You may or may not have some success by preceding the eval with a @ and/or

http://php.net/set_error_handler to trap the error.
Ok, using the @ that would get rid of the error message agreed, but it
still crashes the script (as a fatal error would and should). I took the
code from set_error_handler and that does not seem to work in this
instance - if I called the function with trigger_error then yes, it was
ok, but the memory fail still caused the crash.
Please note here, I dont really want to have to use eval - it is a null
function in this situation, it only seemed (from the manual) provide a
solution to my issue.
Removing the eval (replacing the entire loop with a simple while(true){
$str .= $str . .; } ) which undoubtly would crash after ten or so
loops, does not throw my exception on the fatal error!
There are other possible solutions which we may end up implementing
which include a success monitor, ie each run enteres into a database a
start and a end and then at some other time, another script can
check for scripts that have started but not ended (ie crashed) and
provide analysis, alerts and fixes for.
If you are using PHP 5, a try/catch block may also be useful to consider.
I am not (alas).
I suspect that eval() DOES return false, once you get the error_reporting
under control instead of relying on the rather crude default error
handling.
With error handling as normal, can it handle a fatal error? My issue is
not it would not report a fatal error, it does not continue with the script.
The last issue I am worried about is scope - if I have run out of
memory, then what can I do - I seem to have issues running commands
which go over this limit during the command (irrelevant of their end
memory usage). Supposing I had enough memory to run the set_ini function
and increase my memory limit, then I would be able to execute any
command to roll back (transaction wise) the program execution so far,
and email/notify/whatever. This is irellevant if a success orientated
monitoring method is implemented.

I think a try catch block wouldn't be enough, as most functions throw
warning messages instead exceptions.
You should set a custom error handler and throw the exception by
yourself, if you want to.

Re: [PHP] Re: stream_set_timeout() stream_get_meta_data() etc...
Many thanks to Richard and Skippy.
Skippy: Your suggestion to set non-blocking mode (stream_set_blocking) was the
magic key to success.
Here is the code I ended up with, I left some test stuff included so anyone who
may need it has a good start.
$fp= fopen($file, 'rb' );
if (!$fp) {die (Failed to open $file, errors: $errstr ($errno)br\n);
}//end if
stream_set_blocking($fp, FALSE );
$html= ''; $chunk= '';
$start= time();
while (!feof($fp)){
sleep($interval);
$chunk= fread($fp, 1); //chunks, packets are
limited anyhow
$length= strlen($chunk);
if($length)== 0){echo div style=\color:blue\Read zero
bytes/div;}
$html .= $chunk;
echo divAt . date(h:s) . $length bytes read/div;
ob_flush();
if (time() - $start $timelimit){echo(divstyle=
\color:red\Timeout!/div\n); break;}
}//end while
Putting the sleep() first thing helps everything get started better. Seems as if
fread() needs a little time after fopen().
ob_flush() is neat. It forces the client browser to render progress. I've
always been told you can't make a progress bar or list with php. Well here it
is, at least it works with IE6 and Mozilla.
Skippy wrote:
Quoting Al [EMAIL PROTECTED]:
Darn, I left out an important function, the fread(). Code snip should be:
$fp= fopen(http://www.anything.com/foo.html, 'rb');
if(!fp) {do something different}
stream_set_timeout($fp, 2);
$contents= fread($fp, 20);
$status= stream_get_meta_data($fp);
if($status[timed_out] {do something};
It appears to me there is a basic logic problem. The script must get
past the fread() function before it gets to the stream_get_meta_data($fp).
But, it hangs up on fread() and the script times out.
Set the stream to non-blocking mode (stream_set_blocking). Now all
read functions will return instantly, regardless if any data came
through. You can test whether you got back anything by checking the
returned data. If you now read from the non-blocked stream in a cycle,
you will have no dead times and you will always retain control.
Only now can you rely on comparing time() with a control value set
before entering the cycle and decide to abort if a number of seconds
has passed.
stream_set_timeout() will be pretty much superfluous at this point
and may even hinder your reading from the stream.
Important tip: in a non-blocking cycle you MUST have an usleep()
somewhere. Otherwise that cycle will consume 100% CPU while it
runs. An usleep(1000) will suffice, adjust as needed.

However, by hitting the back button, they can easily go back to the upload one, but I need to prevent that from happening. I know I can't disable the back button, or clean out someone's browser history, so I'm looking for other ways, server-side perhaps, that I can implement to prevent someone from reloading the upload.php page and try to upload another file (which will generate an error because the Java applet still has the old data in its variables.

Set a session variable when the upload is done. Check for the existance
of this variable before allowing the 'upload' portion of your to execute
if ( ! isset ( $_SESSION['upload'] ) ) {

* W Luke [EMAIL PROTECTED]: I've been fascinated by Flickr's, del.icio.us and other sites' usage of these Weighted Lists. It's simple but effective and I really want to use it for a project I'm doing. So I had a look at Nick Olejniczak's plugin for Wordpress (available here: www.nicholasjon.com) but am struggling to understand the logic behind it. What I need is to dump all words (taken from the DB) from just one column into an array. Filter out common words (the,a,it,at,you,me,he,she etc), then calculate most frequent words to provide the weighted list. Has anyone attempted this? Funny you should mention this -- I'm working on something like this right now for work. Basically, you need to: * define a list of common words to skip * define weighting (I weight items in a title and in text differently, for instance -- usually you weight by which field you're using); store weighting in an associative array * define a weights array (associative array of word = score) * separate all text from the column into words (build a words array) * loop over the words array * skip if the word is a common word * increment word element in weights array by the weight The sticky issues are: what is a word (you'll need to build a regexp for that), and how will you weight words (usually by field). Once you have all this, you populate a database table for use as a reverse lookup.

Looks like the Memory limit is hard-coded and won't trigger an error
handler nor will it give you any chance to catch it.
You *DO* have access to memory_get_usage, so you could check on your
memory available to find out what's going on...
There are other possible solutions which we may end up implementing
which include a success monitor, ie each run enteres into a database a
start and a end and then at some other time, another script can
check for scripts that have started but not ended (ie crashed) and
provide analysis, alerts and fixes for.
Looks like you're stuck with this.
With error handling as normal, can it handle a fatal error? My issue is
not it would not report a fatal error, it does not continue with the
script.
I think maybe not -- but maybe only specific errors exhibit this feature.
Memory limit and Time limit could be weird enough to need it.
You could try some other fatal errors to see.
The last issue I am worried about is scope - if I have run out of
memory, then what can I do - I seem to have issues running commands
which go over this limit during the command (irrelevant of their end
memory usage). Supposing I had enough memory to run the set_ini function
and increase my memory limit, then I would be able to execute any
command to roll back (transaction wise) the program execution so far,
and email/notify/whatever. This is irellevant if a success orientated
monitoring method is implemented.
I think you would be well-served to figure out where the RAM is going, and
making sure it's what it should be at various junctures.
Maybe you're trying to patch symptoms instead of debugging the true problem.
Just a thought.
You could also maybe file this as a bug, after searching the bugs database
to see if it's a known issue, or even a feature

Hi! Richard Lynch wrote: Don't take the wrong but you're probably not really skilled enough (yet) to do what you want to do... You're right, but we all have to start somewhere. And I don't take the wrong, I appreciate your answer. sudo is probably the best solution, Well, it's the only one that has been suggested. but you've got a long row to hoe before you could safely implement all the features you describe... That said, if you mostly trust everybody on your Intranet, and if you're willing to put off the Internet access for a long, indefinite time period, you'd be okay if you can prod your users to report oddities and errors, and if you do a TON of security reading between now and the day when you put it live on the Internet. If you don't trust your Intranet users, do this on a development machine that only you can access until you're way way way more comfy with sudo and Linux security in general. Right. Fortunately I'm not alone on this project, and the others might know more about this. I just want to present the best solution to the team, and to implement it in my program. There are 4 obvious ways the users could abuse the elevated privileges: 1) By directly doing something with my program, such as deleting a user. This is not possible without the correct set of permissions. I hope. I've taken great care of this point and controlling rights for user groups is implemented deeply in the program. There are many checks done for this kind of thing. If you don't have specific permission, you can't do it. So this method relies on my abilities as a php programmer, and this possible weakness is inherent to all programs everywhere. 2) By exploiting an error in the system, such as PHP, Apache, MySQL or the file system. These things are partly out of my reach, but there are some things I can do to make them more difficult. Such as NOT running Apache as root, which would be an easy way of solving my current problem. But this is where your good point enters the picture: I simply don't know enough about attack vectors and how to counter them. Just how could a weakness in MySQL be exploited and what can I do about it? The best I can think of is to keep reading and to apply all the common sense and critical thinking I can manage. 3) Session hijacking. I've implemented all the good security advice I've been able to find. I can't really do much more than that. 4) The easiest way to do damage is, as always, by social engineering, getting hold of somebody's password and such. One of the things I've asked for is articles and tutorials, but there apparently aren't any on this subject. I can find many on validating user input, securing sessions and that kind of thing. But not this, no howto make php run useradd safely. I've seen many other people have problems with this, but no tutorials are to be found.

Kirchner wrote: This is probably something that comes up every so often and it's generally related to PHP scripts, however I have a different setup and am now trying to figure out what to do. On our company site, we have a section that clients use to upload files to us through a Java applet. The way I have it setup is basically through 3 separate pages: login.php, upload.php, and thankyou.php. And people go through those pages in sequence. After uploading a file (through upload.php where the applet resides) they get redirected to thankyou.php. However, by hitting the back button, they can easily go back to the upload one, but I need to prevent that from happening. Since you can't stop them from going there, stop them from uploading again. You can store an http://php.net/uniqid or http://php.net/md5 as a token in their form (or Java data) and when they do an upload, compare their token to the tokens already used up -- Putting them in your database or with the upload filenames or... If you detect that, tell them that the Java is broken, and show them the first page to start over, I guess. Can I rely on referrers on upload.php to see where a hit came from? Not really. Or should I redirect to an interim page that simply redirects again to the thankyou.php one (which won't stop someone from hitting back twice, but it's just an extra thing.) What (other) ways have people found that works? I wouldn't rely on re-direction, as sooner or later somebody will hit Back or use the popup in Back to get to the page you're trying to keep them away from. Bottom Line: You can't keep them from getting to that page, so don't try.

Apache was still the user that created the file, and therefore it will belong to Apache until somebody does a 'chown' on the file. Only the superuser can 'chown' a file. Thus, you will need a sudo script of some kind to do the chown, or some way to let the FTP user create the file, then the Apache user's data to go in it. So, some options: 1. Write a cron job as root to chown ftp:ftp /var/tmp/php* This has the severe down-side of maybe someday changing stuff you *WANT* to be owned by Apache. 2. Let Apache move the files somewhere else, like, say: /var/to_ftp/ and then do #1 above. 3. When a file is uploaded, have PHP be able to execute a shell command that has the FTP user create a temp file, writable by Apache, and then Apache can copy its temp file to the FTP temp file by doing fopen/fwrite/fclose. It will still be owned by FTP user, but Apache can fill it up with whatever data it wants. You should add some serious sanity checking on the data when you READ these files, however, if you have untrusted users on the system. Or a routine audit/sweep of all these files to be SURE they are kosher, or... 4. Provide a shell script which allows the Apache user to chown *ONLY* files within /var/tmp, and *ONLY* files that start with 'php' and then Apache can chown the files to the FTP user. Don't give Apache free rein to chown any old file it wants! [shudder] 5. Easiest: Let Apache move_uploaded_file somewhere, and make it readable by FTP user. Have FTP user copy over files from the Apache storage space. When the FTP user creates the new file, it will be owned by the FTP user.

c:\Inetpub\wwwroot\Inpae\admin\lib\headerFooter.php on line 40
All related to $_SESSION, like the values are not set (sitedesc is one of
the indexes of the variable $_SESSION)
But when you first start a session, a totally NEW session, is
$_SESSION['sitedoc'] initialized?
I assume not.
Your problem code looks something like this:
?php
session_start();
if ($_SESSION['sitedoc']){
//whatever;
}
?
PHP is notifying you that there is NO session index named 'sitedoc' yet,
but you're trying to read it and use the value -- the value that doesn't
exist.
You'll need to get in the habit of writing (and re-writing) code like this:
?php
session_start();
if (isset($_SESSION['sitedoc']) $_SESSION['sitedoc']){
//whatever
}
?
You may also re-structure your code a bit if 'sitedoc' can take on several
values, so it ends up being more like:
?php
session_start();
if (isset($_SESSION['sitedoc'])){
if ($_SESSION['sitedoc'] == 'whatever'){
}
elseif ($_SESSION['sitedocd'] == 'something else'){
}
}
?
The point is that you shouldn't be reading session variables that were
never set to any value at all in the first place.
Sure, PHP will initialize them to 0 or '' or false, but the point here is
to catch typos where you have:
if ($_SESSION['sietdoc']){
}
else{
}
If you RARELY expect 'sitedoc' to be a TRUE value, and you don't do a lot
of unit testing, a typo bug like this could go undetected for a long
time.
The PHP Notice warns you about things like this by not notifying you when
you try to read a variable that hasn't been set.

Even FreeBSD my second favorite *nix distro recommends a clean install when moving from, say 4.10 to 5.3, but not Gentoo.. it's all progressive and inclusive. This past weekend I upgraded my friend's Gentoo box from 2004.0 to 2004.3 with no issues. etc-update took me a while to finish, but that was to be expected when you got 151 new conf files to merge. I use it myself for all my workstation and server needs. Good luck on finding one that suits you, though. Yeah, too bad there's no World of Warcraft for Linux. -- Greg Donald Zend Certified Engineer http://destiney.com/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Hi, Sorry i don't really find something useful there. That is cos pdflib is for making pdfs and not parsing them.

[PHP] Foreach problem.
HI,
I am really confused.
I have an array, that looks like this:
print_r($elementsarr) = Array ( [0] = knr [1] = subject [2] = title [3]
= kat [4] = pages [5] = access [6] = dofile [7] = MAX_FILE_SIZE [8] =
pdf [9] = dolink [10] = link [11] = erstam [12] = endless [13] = from
[14] = until [15] = openbem [16] = history [17] = closedbem [18] = [19]
= b [20] = br [21] = bw [22] = bay [23] = h [24] = hb [25] = hh [26]
= mv [27] = n [28] = nw [29] = rp [30] = s [31] = sa [32] = sh [33]
= sn [34] = t [35] = bund )
Now i try to work with this array in a foreach.
foreach($elementsarr as $key=$tmp);
{
echo $key=$tmpbr;
}
Now the result of that is:
35=bund
Ist not the first time i work with foreach. But it is the first time it just
returns the last value.
Do you have an idea why?
Thank you very much

The array that you are trying to use foreach on is a numerically indexed
array (note the [0] = knr, etc) - this might explain your problem!

But, today I have a completely off topic, but somewhat relevant question for y'all. What is your favorite Linux distribution? What would you recommend for my situation? Not sure what your situation is, but I'll answer anyways. I'm brand new to Linux. I'm just trying to learn how it works, but I think I'll catch on quick. I'm looking for the one with the most capability, and also one to run my development instance of Apache 2.0 on. I've been looking at either RedHat or Fedora. Is this a good choice? I'm truly drawing a blank, and I've searched Google, but never really found anything extremely useful. Please help me, an old Windows veteran, escape the Microsoft box! First off, do NOT go RedHat or Fedora. Both are abominations of Linuxdom and are as bloated as Windows. My recommendation for a good binary install distro is Slackware. Minimal set of tools installed for a base system so there is no bloat right off the bat. Gentoo is another good one, but rather more advanced the Slack although the tools are very well documented and once you learn them you'll never consider going to another distro. I really think Gentoo is that good. I use it myself for all my workstation and server needs. Good luck on finding one that suits you, though. Thanks a ton!! I very much disagree. I am writing this on my Fedora Core 3 box and am very happy with it's 'bloat'. As a new convert form windows I am kinda used to everything being there at my fingertips. And in Fedora, everything is, except mp3 support which I added easily with synaptic (the apt gui). I know that I will outgrow this distro, and follow this thread because I am looking for in which direction to grow. But I am very glad that I found Fedora because SUSE, slack, and a few others were way too over my head to get started. I almost gave up. Tips: -If you need support for languages other than english, make sure that yor distro has it built in (Fedora has built in hebrew support for me). Adding it as a newbie is not easy. -Try a live CD beforehand, to check that your hardware will work. -Dont erase windows just yet! You'll know when it's time. Or more accuratly, you'll know that you haven't gotten to that point just yet! -make sure that your ISP will help you setup the internet. I had a real mess with mine, and even switched ISPs. The former ISP's tech support's first qestion was what windows version are you using and if the answer wasn't endorsed by redmont, well, you had no one to talk with! -linuxquestions.org forums!

[PHP] Re: Multi-Page Forms
Hello, on 02/09/2005 01:38 PM [EMAIL PROTECTED] said the following: I have a form which is too long to be useful displayed on one page. I have it broken up into 7 sections. All 7 are generated by the same PHP source file, from data in a database. When the user updates a section they can submit it and go to the next section, or submit it and finish (return to a higher-level page). There is also a navigation form at the top that lets them jump from any section to any other, and uses JavaScript to prompt if they try to jump without having saved changes they made to the page. All of this is working fine. What's bothering me here is that when the user is done editing the data I use their input to regenerate a style sheet (the form allows them to customize the appearance of a web page for their customers). That's expensive -- relatively speaking -- in server load so I'd rather do it only once, when they're really done. But right now I do it every time they submit any page -- i.e. whenever any of the seven pages is submitted, the generation code runs. I don't see any simple way to let them jump around between pages, yet for me to know when they are truly finished with all the data. Of course I can give the required instructions -- after you are done you have to click submit to save all the data but I bet that those won't be read and the users will jump around, fail to save, and then complain that their changes are getting lost. Any thoughts on the design issues here? You may want to take a look at this class than handles multipage forms with pages either as wizard like (sequential access) or tabbed like (random access): http://www.phpclasses.org/multipageforms There is also this generates a single page using Javascript and DIVs to show you only part of the form at a time and links to switch to other pages: http://www.phpclasses.org/wizard -- Regards, Manuel Lemos PHP Classes - Free ready to use OOP components written in PHP http://www.phpclasses.org/ PHP Reviews - Reviews of PHP books and other products http://www.phpclasses.org/reviews/ Metastorage - Data object relational mapping layer generator http://www.meta-language.net/metastorage.html -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

The fact that there are some bleeding-edge developments makes it no different from most other distros. In fact, as far I as I understand, being a 'newbie-distro' it should be rather stable.

In response to parental demands the school has reconfigured its internet WatchDog software to block access to all internet sites mentioning PHP. Officials say this should prevent any other students from falling prey like Brett Tyson did. They have also stepped up locker searches and brought in drug sniffing dogs. Interviews with students suggested that PHP use is wide spread around the school, but is particularly concentrated in the geeky nerd population. When contacted by BBspot.com, Brett Tyson said, I don't know what the hell is going on dude, but this suspension gives me more time for fraggin'. Yee haw! PHP is a hypertext preprocessor, which sounds very dangerous. It is believed that many users started by using Perl and moved on to the more powerful PHP.

Re: [PHP] Problem using return from a class.

I'me just doing:-

If I do
echo $radio_html;
The condense of the variable gets outputted.
I could post the method here but its a bit long.
You only need to post concise code that illustrates your problem, a one
liner to return a value is all the that your method needs.
All I woul post them would be 'retrun $radio_htlm' I will post the
end of the method:
if ( $columns == 0 ) {
$radio_html .= $this-manditoryStar( $manditory );
} else {
if ( $manditory ) {
$radio_html .=
trtd colspan=$columnsp class=NormalText
font color=red size=+1 .
*/font You must select at least one option .
/font/p/td/tr;
}
$radio_html .= /table;
}
$radio_html .= \n\n!--nend presenter.renderRadioReal--\n\n;
// really nagst hack as rtturn not working
echo $radio_html;
return $radio_html;
++$index;
}
This works becouse I echo the varable, but not ideal. The method call
is echo $object-method(...). If the return was working I would get
the code returned twice, but I only get it returned once. without the
'nasty hack' I get nothing;(.

Re: [PHP] Secure system calls -- how
Richard Lynch wrote: Perhaps the reason there is no article or tutorial is that it would be a book, not an article or tutorial :-) There are so MANY affected/related software system pieces that you can't do it justice in an article or tutorial, I suspect. Quite true. However, warnings about don't do this or that, an attacker may use this and so on are numerous, but advice on what to do about it is rarer. And this thing with system calls is a good example: I can find many warnings about not doing it, but not a single piece of advice about how to do it when it's actually necessary. The interaction between your scripts, the OS, PHP and every other script or piece of software on the system comes into play once you start granting special privileges to the PHP user. Here's a method you could easily miss: Create a JPEG that looks like a JPEG in its header, but has malevlolent PHP code in it. Then, upload that JPEG to your server as an avatar or whatever through some kind of file upload anywhere on the system. Then, surf to that image with variations on .php in the URL in an attempt to get PHP to execute that image as PHP code. True, and I do have file uploads for privileged users. I check the files, but how can I be sure? Your example is good, it's very easy to miss the problem with code in a file -- but where's the solution? This is exactly the kind of thing that *CAN* happen by successive small minor mistakes taken one at a time over years of a server build-up, none of which in and of themselves will be obvious as a problem, until too late. Good point, but that's a danger with all programs. Maybe this is a good reason to use tried-and-tested modules like PEAR -- but they can be faulty as well. My main point isn't that I want to be 100% certain nothing will ever go wrong with my program. That's quite unrealistic. But I'm looking for solutions to the problems everybody's pointing out.

[PHP] PHP Development IDE's/Editors
I will apologise for this questions now, but everyone has to start somewhere.

[PHP] errors not reported
Hiya - My parse errors have disappeared from my development environment. Now whenever php cannot run a page, it just stops with a blank page in the browser and no clues. Running the same code on another server will give a fatal error class not found etc type output to the browser. Can someone help me with what other places error reporting (esp parse errors) is configured? What i did: check phpinfo() find which php.ini is being used edited that to set all error settings I could find to on. call error_reporting(E_ALL) in my scripts. but all to no avail! Gak! Are there any other apache settings or other system variables to check? /dc ___ David DC Collier mobile business creator [EMAIL PROTECTED] skype: d3ntaku http://www.pikkle.com +81 (0)90-7414-6107 -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
