Re: [PHP] php teleprogramming -- How to avoid being ripped off ?
Sorry to hear things went down that way, but it 's been discussed many times before on the list... the key ingredients seem to be: 1. get a contract in writing to begin with 2. provide estimates of the time required, and UPDATE THESE ESTIMATES as the brief changes, so that they know that every "little thing" they change will cost them time 3. get a deposit on the estimated development costs OR 4. get part-payments, broken up perhaps into weeks or months... this again gives them a feeling for how much everything is costing, and ensures you get paid along the way... as long as they keep up payments, you keep working... the risk is then only that the LAST month's work is unpaid... clearly a much smaller risk. There are some other ideas as well: 1. keep the code on your server ONLY until payment is made... they should be willing to pay based on completion of the work... when you buy a car, the give you the keys AFTER you sign the cheque, so why should programming be any different? 2. encoding... include little bombs in your encoded scripts which will "break" the code after x months unless payment is made... although encoding is an expensive option. Your only chance is to find yourself legally secure, which comes in the form of signed contracts. If this guy isn't paying, and you have a signed contract, then your only chance of getting the money back would be through lawyers. If you don't have anything signed, I don't like your chances of seeing that money again, or the code.

[PHP] quick sanity check on user management / sessions
Hi all, I just need a quick sanity check. I was going through some old scripts, cleaning them up, optimising them, etc etc... and then I opened my OLD user/sessions management library... For some reason (inexperience probably, or a bad article), it was set-up so that both the uid and pwd were set as session variables, and EACH PAGE on the site checked the uid & pwd against the database... this seems like a lot of overhead to me. Here's what I'd like to do: login page validates user, and registers $_SESSION['uid'] (and any others I need, like admin = true) then, all other pages on the site will just need session_start(); rather than the current call to the database to validate the user on every page. I know the above should be fine, but I'm just checking if there's any reason why I choose to call the DB on every page... it was about 2 years ago, so my guess is "inexperience" :) TIA Justin French http://Indent.com.au Web Development & Graphic Design -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

This is more like a diversion around the problem... It will either be relevant to your problem, or not :) In particular, I use this to prevent people from refreshing their page (and hence adding something to the DB twice for example). Lets say you have form.php, which submits to process.php... the aim is to have process.php as a server-only script (ie, nothing is sent to the browser), with a header() redirect to a thankyou.php page once I've added stuff to the DB, or whatever The point is, they'll never see a page expired message in this case, because the script receiving the POST information never gets to the browser.

I don't think I was being clear enough at all :) 12px is 12pixels... there is no way for it to *reliably* be reset to 14px, or 10px by the user on all browser. In the current versions of IE for Win, using the text size larger smaller or % options in the menus has no effect whatsoever if values like 12px or 12pt are given. If you specify 12px, and I decide I need it bigger, I don't have many options, other than totally overwriting your style sheet with my own (no thanks!, and beyond most web users). The good news is that because 12pt and 12px are so prolific on the web (and so evil in terms of accessability), browser manufacturers are now beginning to make px and pt variable sizes as well. That is to say, in IE5 Mac, NN7 (and maybe 6), and some other browsers DO LET YOU CHANGE THE FONT SIZE FRONT THE MENUS, selecting smaller, larger, 120%, or whatever. The bad news is that the latest versions of IE6 (at least 3 months back when I did some major CSS testing) did not let users do this. It's well documented, and people like Zeldman and A List Apart have spent months campaigning for IE Win to match IE Mac and NN on this. Here's a snippet from http://www.zeldman.com/daily/0702b.html > To satisfy the demands of accessibility within the context of normative > practices in commercial web design, IE/Win needs to do what IE/Mac did in > March, 2000: implement Text Zoom, so visitors can resize any web text.

So, I stand partially corrected, the user CAN override ALL font size by digging into the accessibility menus, but I seriously doubt many do. If the latest versions of IE *DO* allow text zooming via the menus, again I stand corrected, but there are millions of web users out there on IE5 and IE6 without text zoom. IMO, specifying a px or pt font size is taking away the users right to choose what font size they prefer to read with, IF they are using IE4/5/6. > No, the problem he stated was the inconsistency of sizes on different > platforms.

Turn register globals off (as you have). Then NEVER pull any data out of the $_COOKIES array, and you're now "ignoring" cookies :) Perhaps a further step is to call something like unset($_COOKIES) at the top of every script... but I'm not sure how unset() works with the super global arrays.

It could be any proxy server between the client and the server, plus any proxies ON the server... this would include the user's local machine, their local network, their ISP, and any ISP/server in between the client and the server (do a traceroute), althoguh in this case it sounds like you're talking about a LAN. I don't *think* Apache caches anything by itself. Of course changing the filename will ensure you aren't using a cached copy :) Justin French http://Indent.com.au Web Development & Graphic Design -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] Decrypting mcrypted strings on Windows desktop
I've done something similar (encrypt a message, send it to a client, let them decrypt locally), and so far, the easiest solution was to simply install PHP and Apache on their PC. You could also check out PGP-GTK, which is a cross-platform, client-side extension to PHP for making GUI's... haven't worked with it yet, but I plan to soon. on 03/12/02 9:32 AM, Geoff Caplan ([EMAIL PROTECTED]) wrote: > I need to encrypt short strings in PHP, using mcrypt by preference, > email it to the customer, and have him decrypt the string on the > Windoze desktop. > > But all the Windows encryption utilities I can find use proprietary > file formats - none can decrypt the string output by mcrypt.

[PHP] easiest way to get 1st and last dates of the month?
Hi, I'm looking to get a unix timestamp for the first and last day of a month, given a timestamp. But so far everything i've come up with has been wy too many lines of trickery -- especially for the last day of the month (which isn't always 31) Any ideas or snippets of code floating around?

Re: [PHP] hiding php
Why not just make up an extension, like your initials (.lsb) or your business name (.dim or .dni), and set-up apache to pipe all those files through PHP...?? That way they'll have no clue at all (if used in conjunction with the "hide PHP" stuff, etc etc).

Yes, and they get discussed on this list almost daily... a quick search
would have helped.
1. the "script" that does all the validating and inserting SHOULD NOT send
any output to the browser... after insert, put in a header("Location:
script.php?action=thanks") style redirect.
This means that if the user hits refresh, they will only be refreshing the
"thanks" page, NOT the insert page, because it never gets to the browser.
Yes, this can all be done in one script, it may need some re-organisation
though.
2. when generating the HTML form, include a hidden field with a unique
string in it. Insert this string with the rest of the form data, and make
sure that this string is only inserted once... so, if they hit "refresh",
you'll know that the form has already been submitted, and the data already
inserted, so don't insert it again :)

If you're installing the App on various servers, clearly there needs to be SOME form of configuration upon installation... the document root could be in a different place, the database username and password stuff could be different, permissions could be different, etc etc. Generally this is achieved with an include()'d file, which keep all your config vars in one spot. Since a heap of my sites run on shared servers, I don't like the idea of central shared configs -- well, at least not above the config settings in php.ini and at .htaccess level. Speaking of which, PHP can be configured to automatically include a certain file at the top and bottom of every script that gets run. I think the php.ini directive is auto-prepend, or something like that... Perhaps this also address' your application variables question too? > Even with this being said, I'd like to use PHP for our application if > the 2 issues above can be resolved. I'm not up-to-speed with CF, so I can't address your exact issues, but I know that there are thousands of large enterprise sites running PHP (yahoo for example), so there MUST be a way to achieve everything you need.

Re: [PHP] Creating dynamic names for images
well, a) use a table in the DB with the primary key (id) as an auto-increment column. 1, 2, 3 etc. Use this ID as the name of the file 1.jpg, 2.gif, and perhaps store the filetype / extension as well, so that you know what filename to look for in the folder. b) something as simple as file_exists() may be enough... if a file with that name already exists, you could append something to it, like a random number, and try again. Ypu certainly don't have to ask the user to rename the file... YOU should be in charge of naming it.

Re: [PHP] String to an Array
I *think* either: OR Works -- you'll have to experiment, but I believe the second way is correct, and will echo the first (0th) character in the string. If you want to get more than 1 character from a string (example, characters 2-5), then use substr() -- check out the manual. So far, I don't think you've shown a need for the string to be converted to to an array...

Re: [PHP] Dumb session cookie question?
if you are allowing cookies on your browser, and the sessions are working (as they appear to be), then there WILL be a cookie somewhere on your browsing computer. However, I think you're a little confused about what you'll find... you'll just find a cookie named PHPSESSID, with a value of XX. A common misconception about sessions is that the session vars get stored on the user's computer... WRONG. ONLY the session id is stored on the user's computer (either in a cookie, or via the URL). Session vars and values are ASSOCIATED with that session id ON THE SERVER. WHERE exactly the cookie is stored on your CLIENT (viewing) hard drive will depend on the OS, Browser, and a heap of settings. WHERE exactly the session vars and values are stored on your SERVER will depend on a few PHP settings. What are you trying to achieve? To test if a cookie exists on the user's computer, you use the $_COOKIE array. To assign values to a session, you use the $_SESSION array (which associates a php session id (stored/carried by the user) with a bunch of session vars/values stored on the server).

[PHP] date() on two diff. servers
Hi, I'm running the following code on two servers: On my local development box (Free BSD, PHP 4.1.1, on AUSTRALIAN time), the above echo's "Wed, 11 Dec 2002" (I consider this to be the "correct date". However on the live server (Red Hat, PHP 4.2.3, hosted in CANADA) the above code echo's "Tue, 10 Dec 2002". Now, what could be causing this problem? IMHO, no matter where you are in the world (or more to the point, what timezone you are in), 1039525200 seconds after a certain date (in this case the unix epoch) should be another certain date, yes? What could be causing this difference? What should I talk to my host about, or look for?

Note, I don't believe there's anything wrong with the stamp itself. The point is, the stamp is displaying as two different dates using date() on two different servers, and I believe this is not what date() is supposed to do. Shouldn't the stamp for 12-09-2002 22:13:09 be the same on every server? My rationale for this is that no matter where you are in the world, it is always a certain number of seconds since 01-01-1970 00:00:00. Perhaps strtotime() is NOT running off GMT, and perhaps date() is... there has to be SOME confusion there -- either on my side, or in my choice of functions, or SOMETHING :) Justin French http://Indent.com.au Web Development & Graphic Design -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] How know from wich page you came from
*SOME* browsers set a referrer script name/url, and some don't, so you can't rely on it. The solution can be as simple as including the referring script as a GET variable in the URL: click Or, by keeping track of that sorta stuff with sessions... Whenever I *have to* know the URL of the preceding script, I take the directory, script name and query string eg dir/dir/page.php?var1=foo&var2=bah and base64 encode it (so that the get vars don't register with / affect the receiving script), and pass it to the next page: click On page.php, I decode it all with base64_decode(), and I know exactly where the user "came from". Similar (or even smarter) stuff can be done with sessions.

Re: [PHP] Passing variables from script to script
1. the only other ways to pass things around would be in sessions, or by setting a cookie on the user's computer... i hate the latter, and would prefer the former, but would NEVER carry things like a MySQL uname and password around in cookies or sessions. cookies, sessions, and even post & get (url) should be used for user-specific things (who are they, what are they asking the server to do), not program-related things (like the database password, or the global font size, or the site admin's email address... this is generally done with a config file or other included file: 2. you could define your vars (like the MySQL uname and pword) in a config file, and include it at the top of all your PHP scripts: ... 3. you can extend this further, by setting a value php.ini (auto-prepend I think) so that PHP will ALLWAYS includes the config file at the top of every script.

Re: [PHP] fgetcsv Help
How is the CSV being generated? Seems to me like your problem isn't
ggetcsv(), but rather the file itself.
Commonly, a CSV file is a series of values, separated by a comma (duh!!).
The separated values are generally enclosed in double quotes ("), as it
would appear yours are.
Any double quotes within each value (eg: she said "hello") are escaped with
a slash (eg: she said \"hello\").
If you are generating the CSV, then you can addslashes() to each value to
escape the quotes, and then later on, stripslashes() to get rid of them.
Sample line from your CSV should look like this:
---
"1","foo","harry said \"what is it?\"","foo"
"1","bah","\"don't know\" said sally","something"
---
When echoing these values to the browser, you would strip the slashes.
Cheers,
Justin

Re: [PHP] A little regex help
Not sure if it will be quicker or not, but I don't think you NEED a regex:
- get rid of 'for more information'
- split on 'See' into $pre and $code
- trim the bits down
- wrap $code in a URL
- glue it all back together
UNTESTED CODE:
http://support.microsoft.com/default.aspx?scid=kb;en-us;";;
$suffix = 'for more information';
$splitter = 'See';
// do it
list($pre,$code) = explode($splitter,$str = str_replace($suffix,'',$str));
$pre = trim($pre); $code = trim($code);
$str = "{$pre} See {$code} {$suffix}";
echo $str;
?>
If this gets heavy traffic, u may want to test which is faster -- or you may
not care!!

Re: [PHP] migrating from register_globals on to off
Why not: 1. place a .htaccess file in each existing client/developer directory switching the value to ON -- being careful to ensure you don't wipe over an existing .htaccess file!! 2. switch the value to OFF in php.ini This means all current clients will have continued support for ON, and all new ones will default to OFF. If existing clients which to go with OFF, they just delete the .htaccess file. OR the vice-versa can be done... advise clients that you are moving to OFF in a month, explain the benefits, and make a .htaccess file available to those who don't want to migrate... so that their stuff doesn't break. Most developers will know which way they're writing code. You ultimately need to: - change the default to OFF - allow existing clients to "patch" to ON Justin on 15/12/02 12:43 AM, Willem ([EMAIL PROTECTED]) wrote: > Hello, > > Lately we discovered that, by mistake, we've run PHP with register_globals > on for a few months for all our customers. > > Since we want to turn it off, we need to figure out which customers use the > 'register_globals' functionality so we can ask them to modify their scripts. > > However, checking all php code by hand is a non-trivial task, because there > are 20,000+ php scripts.

Re: [PHP] Session: I RTFM
John,
PHP looks for "$vars or {$vars} to parse in the string" when double quotes
are used... whereas when single quotes are used, it won't parse/substitute
the vars.
So, when you're not using $vars, using single quotes will be marginally
faster... perhaps not important on small sites, but very important on big
ones, and a decent habbit to get into :)

Re: [PHP] php setup
Check phpinfo() on both the new and old server -- i think the var not defined stuff is related to a different (higher) error reporting directive on the laptop. As for the images, view the actual SOURCE of the resultant HTML page (browser > view source) and see how the image src's are being written, then check for the files directly -- my guess is you're dynamically writing the image URLs, and something is breaking (possibly needs register globals ON in php.ini). on 17/12/02 6:29 AM, Edward Peloke ([EMAIL PROTECTED]) wrote: > I recently got a laptop and was in the process this weekend of installing, > php, apache, mysql etc. One thing I noticed is when I ran the code (that > works fine everywhere else) on the laptop, I got errors of 'Variable not > defined' and I have pictures that just won't show.

What do you mean "don't work"... what are you trying to do?
page1.php
click to go to page 2
page2.php
The value of $_SESSION['today'] is .
This code assumes you either have trans-sid compiled OR are allowing cookies
on your browser AND cookies is a method that PHP sessions use (it is by
default) in php.ini.

Re: [PHP] login
You really need to check out sessions. 1. user logs in by a form 2. php validates the login, checks for a valid uid/pwd 3. if valid, sets a session variable like $_SESSION['uid'] 4. you put session_start() at the top of each page, and php will know that they are logged in as "justin" or whatever. Rather than passing around thier userid in the URL, you pass around a session id (long unique number) in the URL, and associate MANY session variables to it via either the URL or cookies (userid, first name, fav colour, preference for font size, preference for date format, whatever) on the server-side. The guts of it is a lot more complex than that of course, with many different options, but you get the drift :) What you would actually be testing for on each page would be $_SESSION['uid'], not $clientid or $_GET['clientid']. There are some simple examples on: http://www.php.net/manual/en/ref.session.php Cheers Justin on 21/12/02 1:20 AM, Edward Peloke ([EMAIL PROTECTED]) wrote: > Ok, > Newbie Question. > I know have a login and registration page on my website.

Huh? I can't really understand what you're saying.
If you're adding stuff to a database, and getting an error, use
addslashes(), then on the way out of the database, you need to
stripslashes(). Easy.
If you don't get any errors, then magic quotes is probably enabled in your
php.ini file.

Re: [PHP] Which one to use..
I use:
if(eregi('index.php', $_SERVER['PHP_SELF']))

although it'd be quicker without the eregi() call, as long as you knew the
full value that PHP_SELF would return.

META refresh is the only standard, HTML way to do it, AFAIK -- and even then, i'm not 100% sure that all browsers and user agents support it. Another option would be for javascript to refresh the page, but again, this will probably invoke the IE clicking sound.

Re: [PHP] Re: Securing areas of a web site with PHP
A lot has been said on the issue already, so I'll attempt to keep mine brief. Cache control will help a little, but not all browsers support it. Yes, it will cause a little more traffic on your site, and yes it will "help" keep some people from clicking back, but it certainly won't FIX anything. Javascript can disable back buttons, but i've never used it, because a) I hate javascript b) you can't rely on javascript to be available c) i don't like forcing people to work a certain way d) there are always work-arounds I know it sounds simple, but try to analyse what other big sites are doing in this situation: - amazon.com doesn't seem to "break" when I disrupt my surfing with a login or logout... it just picks up the pieces and does what it can. last time I bought stuff there, I certainly didn't notice any caching issues, or that my back button was disabled. - my bank, the national bank (national.com.au) pops up the entire secure banking process in a new javascript window... essentially, this starts a new process for the user in a new window. when they log-out, the window is useless and is closed... there is NO clicking back if the window is closed :) I guess the national were concerned enough about back buttons and all that stuff to require javascript in order to use net banking... you'd have to make your own assessment of that. If there's a big issue with people clicking back, I'd suggest that there *may* be a problem with the logic of your site. Afterall, clicking "back" is what the web is about!! If the big sites can cope with it, I'm sure you can. In short my solution is that if you CAN'T live with people clicking back, then you should open the sensitive content in a new window which is auto-closed when the user logs out... this way there is no hope of clicking back. Yes it requires javascript, which means you have to think hard about ignoring a % of your users.

Re: [PHP] Using mail() for mailist list app
Check the archives... mail() tends to "break" pretty quickly... sometimes on less than 100 personalised emails... The issue ISN'T mail() itself, but things like server timeouts, script timeouts, etc etc. The issue also isn't really HTML mail, but more the fact that each email has to be sent to the mail que, and this is a slow-ish process, so the script timesout. So another option is Bcc'ing the email to everyone in a non-personalised manner... you can squeeze a lot more emails out of mail() before the script times out, but you will run into other issues like: a) Bcc'd mails of more than 100 recipients can't be sent on most shared hosts, because it looks like spam -- check with your ISP b) some mail programs and servers treat mass Bcc emails as spam, I hear At the moment, I've only got mailing lists that deals with 50-300 people, so I'm just Bcc'ing them in batches of 20 people... a trade off between lots of emails to timeout the script, and lots of people in the Bcc list. I think for 6000 though, you will really need to look at a class like Manuel's at PHPclasses.org (I think called mimeMail) which has various work-arounds, none of which I've tried.

Re: [PHP] Sessions & Security
Hi, There's actually another thread on this topic at the moment... quick summary: 1. you can't rely on the IP address 2. you can't rely on the referrer It's been suggested on the list that you could record the user agent into the session, and check against that -- keeping in mind that the user agent may be null, and that this would not prevent someone with an identical useragent from hijacking the session... it's more like an added layer of protection :) Check out the recent thread "prevent session_replay" Justin on 03/01/03 11:36 AM, Duncan ([EMAIL PROTECTED]) wrote: > Hi, > > i am currently working with sessions and how to secure them as much as > possible. > In an older script of mine, i used session_is_registered() to take care > of this, but according to the manual: "If you are using $_SESSION (or > $HTTP_SESSION_VARS), do not use session_register(), ..." - i can't use > this anymore. > Well, so i wondered: how do you or would you make sure that s.o. won't > be able to hijack the session? > Also any recommended URLs about this matter are more than welcome as well :) > > I am currently only checking the IP, but i read about issues with AOL > users about this, since it can happen that their IP changes while > browsing the site. > S.o. mentioned checking the referer and so making sure, the script comes > from the own server, but when using redirects or stuff like that (or the > browser doesn't support this properly - as read in the php manual), then > this isn't 100% working as well. > > So, start nuking me with your comments ;) > > Regards, > Duncan > -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
