Re: [PHP] Re: MySQL - PHP combined log
Well, I think the solutions or ideas are maybe a bit too involved. I was hoping that the errors I am interested in were already logged by default to some obscure location, and I *could* if needed just go and scrutinize them by hand. But, it seems like a detailed (specially mysql) error log does not exist and thus cannot be scrutinized. Reading some of the possible solutions regarding adding error_log() functions to existing code leads me to believe that it could be easier to maybe incorporate those functions into PHP by means of a switch in php.ini, one could theoretically have two sets of functions, a mysql_query() for normal use that acts as we all know it, and another mysql_query() (yes, with the same name), that has the error_log() function call built into it, and the one that gets used is determined by the (lets call it) mysql_error_log = on in php.ini. This way, the entire thing will be transparent to both users and existing/future code. Granted, I have no idea how PHP is coded behind the scenes and if something like this is even possible, it's simply an idea, and hopefully some of the more learned people on this list will be able to comment on the feasability of something like that. Dave wrote: clipped how about this curve... getting PHP to append a line to the apache log. How about reading the documentation? Deserved that for not being clear enough... see below. My apologies if I missed the word access log or even assumed you meant error log when you just said log.I shouldn't have. RTFM never hurt anyone :) You're right, you can't do that, without opening up security more than you want to. *ACTUALLY*... There *probably* is an Apache function for access logs just like the error logging one that PHP is using, and you could *PROBABLY* patch PHP with some dead-easy copypaste to use it, and you could even submit that worthy patch to the PHP Group. I suspect it's not there only because nobody really saw a need for it. I've never had a use for it untill now, wanting to charge a customer for massive uploads via file_upload forms... transfer that is not recorded in the apache logs and therefor not collected for billable bandwidth (while still preserving IP addresses and avoiding a ipfw counting per IP). Probably a requirement with limited scope. It's kinda icky that you'd almost have to use 4 (the next unused number) for Apache access log with 0 being Apache error log and 1,2,3 being other stuff between... Maybe -1 for access log? Ew. That's not 'right' either, but maybe it's 'less wrong' than 4. icky, I agree Damn things shouldn't have been magic numbers in the first place. Should be constants. Hey, while you're in there, make up some decent constant names and let's migrate to them and then deprecate the magic numbers and fix it right :-) :) Another option might involve some sort of nasty named pipe stuff and redirection and whatnot, and you *MIGHT* be able to have a file that you error_log into, but it really just ends up going into the Apache log... There may be some risk of corrupting your access log, however, if any incredibly *HUGE* entry over-steps the atomicity threshold for file appending in Linux... sounds like a nest of potential problems Not so sure it's a Good Idea anyway to have two programs trying to write to the same file at once if it can be avoided. thus the interim solution of having PHP write to a seperate log file, then doing a merge/sort during rotation time. Will look into it to see if something can be presented without creating more problems than the solution is worth.

[PHP] When to destroy sessions that iterate
Prolly a silly question, but I have a session process that never really ends as it is supposed to allow the user to carry on submitting etc. So I don't know where and when to end the session, and if it is really nescessary to end a session? Obviously a logout button will do the trick, but what about aborting users that don't bother to logout? I presume a session will have a timeout value? If so, how does this work? Surely there can't be a physical time allowed for a session to stay alive? What about if I want to have an intranet application that could ( and preferably should) be able to be open indefinately?

Re: [PHP] Help with msql_fetch_array()
I can almost guarantee that it's not the second line that is failing,
the problem here is that $result is not containing naything, and that is
normally due to the fact that you are not connecting to the db, or the

I use the following format as my standard MySQL connect and query snippet:
$link = mysql_connect(localhost,$username,$password) or die ('Could
not connect!'); // suppresses the default error message generated by
this function and the or die() bit kills the script right then and
there should it not be able to connect.

from it.

} else {

This is not a valid way to check if the query has returned anything.
mysql_query() returns FALSE on error. So if there was no error but there
also wasn't anything returned then the object stored in $result wiill more
than likely evaluate to TRUE. For the determining factor you should count
the number of rows with mysql_num_rows($result). If the returned value is
zero then you know it hasn't returned anything.

Re: [PHP] Re: MySQL - PHP combined log
Thanks, but all these methods require modification of the scripts already on the server, and it won't ensure any new script being written by a user on my system to comply. Are you all saying that there are no logs kept by default of errors generated on php/mysql pages at all unless specifically coded? Wouldn't it be possible then in future PHP releases to have a set_error_logging directive in the php.ini file that will automatically run a wrapper function on all mysql_query() functions to do this kind of thing? How are people out there managing the scripts/script errors caused by users on their systems? Or is it a case of handling the crisis when it happens? You see, as administrator, I need to be able to quickly see who are coding in such a way as to leave security holes, or even worse, cause the server to crash due to poor coding. There are almost 1000 individual php files on my server, and it wouldn't be possible for me to scrutinize all of them to make sure they are OK. Are there any admins out there that have policies about scripting practices on their systems; ie, checking a script from a user before it is allowed to be uploaded etc?

[PHP] Sessions without cookies : forms
Hi, thanks for all the replies on my two previous postings relating to sessions and cookies. I have set my mind on using sessions but without cookies, so that entails passing the SID via relative URL's. My problem comes in here, when I create a simple login page with a form that send username and password to the next page, I start_session(); and then in the form action, I append the url with ?=SID? , but that causes two parse errors.

[PHP] Sessions: watertight?
Hi I'm doing some reading on sessions and how it works etc, and have a concern (which is probably fed by my ignorance on the topic). The couple of simple session examples I have found in the PHP/MySQL book by Luke Welling Laura Thompson gives a simple 3 page session example where the session is started on the first page, a variable is registered as a session var and then has a link to the next page where the session_start() is called and the session_var is echoed to illustrate the workings of a session. My understanding is that PHP will either use cookies to store the session ID on the client's pc, or send it via URL, so, assuming that cookies is a no-go, can I now assume that PHP will attach it's session ID to each and every URL located on my .php page? The reason I'm asking is as follow: I did the little excersise, and then deliberately rejected my browsers call to process the cookie, and then the script didn't return the variable as it did previously... And now, assuming that I can assume that PHP will attach the SID to all URL's , how does it know to which URL's to attach, or am I supposed to manually attach them, leaving me with another question, If I have to manually code the SID into the URL, then the whole session coockies if possible approach doesn't seem to work???

Re: [PHP] Sessions: watertight?
Thanks OK, I have checked my phpinfo(); and the *session.use_trans_sid* = 1 ; *session.use_cookies =* On, so I'm not sure if I need to turn the cookies bit off, but I would think it not to be necessary. ; So, I can't see why the URL's aren't changed on my pages... Now, something to contemplate so long; say I DO get the URL bit right, what method does PHP use to determine which URL's to append? Would this method have a considerable overhead on performance? ( given that there could be alot of session usage on my domains). I'm rather interested in the workings of this URL detection, as it basically means that PHP runs forward through all my pages to see where the session stops and and it's difficult for me to see how PHP can tell which pages have to do with which sessions. Arguably one can have two session threads that has some overlapping files, and my mind boggles as to how php can track the session vars, secially if the one session thread were to use the same session variable names ( which is surely possible right?) I guess my question is very academic, but I'm trying to understand the workings of sessions.. But for now, my main concern is getting PHP to work it's magic with my URL's. Thanks [EMAIL PROTECTED] wrote: Taken straigh from the manual: (http://www.php.net/manual/en/ref.session.php) [quote] There are two methods to propagate a session id: - Cookies - URL parameter The session module supports both methods. Cookies are optimal, but since they are not reliable (clients are not bound to accept them), we cannot rely on them. The second method embeds the session id directly into URLs. PHP is capable of doing this transparently when compiled with --enable-trans-sid. If you enable this option, relative URIs will be changed to contain the session id automatically. Alternatively, you can use the constant SID which is defined, if the client did not send the appropriate cookie. SID is either of the form session_name=session_id or is an empty string.

[PHP] Cookies - good or bad???
I'm really battling with this whole session thing. My first impressions are that cookies are OK, and really helps to make sessions workable and efficient, YET, from a developers point of view, I always play devils advocate, and I'm wondering about those stubbourne individuals out there who outright refuse cookies; rendering my application useless unless I code a plan B into my code; meaning I can just as well NOT use cookies from the start... catch 22 dejavu... What are the general feeling out there amongst developers about the use of cookies? I'm concerned about the following scenario specifically: I develop my great application using session controll - which uses cookies by default, or alternatively adds the sid to the relative URL's on the page, YET, from responses to my previous posting, I gather that the alternative url method is not 100% the same as the cookie method inthat it doesn't work with IFRAMES etc. Leaving me to think that there will potentially be people out there that will NOT be able to use the application, that could lead to messy discussions between developer and client... Before I started to read up on sessions, I simply used my own form of session management by sending all relevant variables either via URL or via form fields to the subsequent pages. Obviously this method leaves a bunch of holes as well, but I KNOW that my application is always pure and simple HTML, doesn't have browser issues, doesn't have cookie issues, so 100% of the internet community can use it. Does anyone out there have a view/practise when it comes to session/cookies? - basically I am still not convinced that using sessions/cookies is a good idea, but I would love to be educated as to why I should... -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP] Register Globals = off
Hi Going through some literature, it seems like the use of registered globals can cause security issues. Now, the dilemma, all my previous PHP installations ( for the last year or so ) have come with register globals = on in the php.ini file by default, and users on my system has happily coded their websites using this function. Now , with all the new versions of PHP, the registered globals are turned off in the ini and will basically cause all those previous sites not to function. Which means that I'm between a rock and a hard place, turn the register globals back on and carry on with the security risks, or keep it off and have all those people re-code their sites... Is there a more gentle solution out there? Am I just misunderstanding the issue? Any light on the matter will be appreciated.

[PHP] Sessions : see also Tracking file downloads
HI While waiting for responses on my first question, I've done some reading on sessions, and came up with the following questions: First, I have been coding with PHP for a while without knowing about sessions, and have completed a couple of rather large projects without using sessions as such, yet, much of what I have read on sessions, I have done manually already by creating my own unique id's and passing them on via url to the subsequent pages. So, here is my question. Is sessions basically just that, made easier , or are there fundamental differences/advantages. I know (now after reading a bit) about the use of cookies etc if availale when using sessions, and that you cannot overwrite a session variable by passing it via url, but are those the only differences? So, basically, do you really HAVE to use sessions, or is it like most other things in life; there are more than one way to skin a cat. Are there set rules or guidelines to when one would definately absolutely have to use sessions?

[PHP] SMARTCARDS - PHP + MySQL
HI I would like to hear from anyone who have possibly worked on implementing a smartcard solution to controll access to a website. I am looking into possibilities for a proposal, and one of the requirements of the client is that the system data has to be accessible via the web, and that the access to the information has to be extremely secure. The administrators of the site as well as the clients will need to be verified with ( ideally ) smartcards. Obviously, you can deduct from this that the system will not neccessarily be implemented on the internet, but most probably WAN. It looks like the clients or users of the system will be physically required to be in front of a terminal connected to the system ( and it will have a smartcard reader) I have never worked with smartcards before, and am not sure how one would ( if possible) integrate or pass the access signal through to the php/mysql pages. Also, the user stations will most probably be Microsoft machines, but the servers will most definately be Linux, and if possible, I would like to have a smartcard verification solution on the servers as well ( this is not THAT, important, but seeing that the administrators might also want to work from Linux boxes, I would like to know if it can be done on a Linux platform). So, in a nutshell, it's almost like a normal postoffice scenario. People will come to visit the establishment and produce their smartcard to verify their identity to the clerks who will then be able to transact via a webinterface with the servers. Hope this is clear enough?? PS, I'm not trying to be cryptic, it's really all I know and most are deductions I made myself from reading the initial drafts. Thanks for any help. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Script executes for longer than 30s
HI I wrote a basic script that takes the input of a textfield and passes it onto the system() function and then echo's the result, somethinglike this: ?php $result = system($command); echo $result; ? The $command is sent from the previous page via text field. Whe I test this and do something like ping 192.168.0.2, the page keeps on growing and growing, way past 30seconds. My php.ini file is definately set to 30s timeout. Is there something wrong or do I have a misunderstanding of the timeout workings?

Re: [PHP] Script executes for longer than 30s
Hi Chris The script is not meant to run ping, I just used it as a test and then noticed that it does not time out as I would have expected. The problem is thus that if it is used on the command it is intended for and that command actually just keeps on going and going for whatever reason, I might end up with a problem where I expected PHP to take care of it for me Chris Hewitt wrote: If I may respectfully suggest that you do not use the php scipt timeout to limit the number of pings but ensure that the system command will finish within the required time. The former seems a poor technique to me. In your example, the ping command will never complete (unless php closes it down). Why not limit the number of pings with ping -c 10 192.168.0.2?

[PHP] Self Destruct code
Hi I have a funny request; I wrote a system for a client and am rather concerned that I am not going to receive payment for the work done. They want me to hand over the code before they are willing to pay, so basically I will be left at their mercy; if they don't pay, they will still have a working version of the system... So, is there any way I can inconspicuously code in some boo-boo's that are time related etc. Something that will bomb the mysql tables or break some code if it is not unlocked within a month etc. I'm not sure if people out tjere might have existing safeguard tools etc, so I'm open for suggestions. PS, I know about Zend's encrypter, but since it will live on their server, I don't think it will help much since they will need the decrypter on there anyway right?
