[PHP-DB] Duplicates
Howdi all, How can you list the contents of a table and skip duplicate Dates?? eg select Date from table_name where name = 'Test'; |Date| 2000-01-01 2000-01-02 2000-01-02 --- How would you get rid of this duplicate date (without deleting it ;-))? I want to just get a list of dates in the table that querys have been inserted, but not duplicate dates... Say for instance I had 1 entry on 2000-01-01, and I had 10 entrys on 2000-01-02 I want it to tell me that there is a date for 2000-01-01 and a date for 2000-01-02, not for it to tell me there is 10 entrys on 2000-01-02 Any help would be appreciated Many Thanks guys -- Chris Grigor Calibre Clinical Consultants -- -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP-DB] Echo Command Thanks
Hi there everyone, Thank you all for your responses to my question about the best way to end a PHP command (Or use Echo to print HTML). My gut feeling was it should be ok, it's just that *To me* it is MUCH easier to follow code which doesn't contain echo table width=50 etc . I much prefer to do it ? table width=50 and so on, it seems to look much cleaner to me. I'm not a C+ programmer, a Perl programmer or anything like that, i've learnt ASP and PHP, started with ASP but found it to be a system hog, tried PHP and fell in love with it within a couple of days and just wanted to make sure I wasn't putting unecessary strain on my server :-) Thanks again everyone, this is the best PHP / Programming mailinglist out there.

Darren Henderson [EMAIL PROTECTED] wrote... : 1. Anything more than just one single PHP file made in your text editor. Not sure what you mean by this. If I write a single suite of data handling routines then it doesn't matter if I have one or 10,000 pages using it. I meant a file to write and store the data. A configuration file, for example. 2. Dynamically modifying your configuration files. File locks? Not a hard or complicated thing. But isn't a RDBMS easier and safer at that point? A very big point, actually. 3. Per-user based configurations like to store things for later, frequent use. ndbm type solution is much better suited to this unless you have complicated querying requirements. And unless you are dealing with many users a simple unix type password table or user configuration files is perfectly sufficient. Yes, if you never have to touch individual user's data from within an admin area. But, if you want to do more things than just loading variables - you need querying each file :) 1. Simpler developing a database in SQL than in some Flat Files logic. This means investment saving. Sessions are ideal. SQL buys nothing at all but complexity. A shopping cart is a list of items - you do not need to do multi-key/foreign key look ups to deal with it. I didn't talk about sessions and multy-key/foreign-key staff yet. All I want to mention is that, creating a logic between Flat Files is not a simple thing, and, often, SQL usage will be easier. Unless one doesn't know SQL at all and take really long time to start using it. Files are more intuitive, true, but less complex than SQL. Consider this for displaying an item out: ?php $link = mysql_connect(mysql_host, mysql_user, mysql_password)); mysql_select_db(my_shop); $result = mysql_query(SELECT * FROM products WHERE product_id = $id); $product = mysql_fetch_array($result, MYSQL_ASSOC)) ? Againsts this: ?php include(/a/huge/file.php); $product = $data[$id]; ? Easier with files, no? But, s limited... for a shopping cart is not optimal at all. You will have to be quite experienced to write data in PHP syntax with a solid logic and locking files. If you are, then your experience will tell you - just get a DB, it's better. So if you've written your applications correctly Let me cut it here: if one writes an application correctly - it means it will write it with a DB, not flat files for a shopping cart. I would much rather worry about that then worry about backing up data bases, every RDBMS has such utility. checking to make sure I can talk to the db What about checking to make sure file is still writable (by anything on the server?) dealing with network outages Not always a need. dealing with speed issues, RDBMS is faster in most cases, and, even if not then the downgrade rarely goes over 1-10 milliseconds for things accomplishable also with Flat Files. especially in a heavily shared environment as exists in most/many hosting companies. believe me, files are worth in these cases :) Until recently MySQL didn't have transaction protection. In many hosting environements it isn't offered. If you are not using the roll back capabilities of the latest versions of MySQL then you do not have data integrity. Data integrity is not only everything we hear about Oracle and what mySQL only now is trying to implement. Data Integrity is also knowing that the data is controlled by an application specialized in that. If you need a real data integrity look for PostgreSQL that is Open Source (or expensive Oracle which is the maximum of Data Integrity logistics). The password needs to be stored somewhere on the file system - there is no advantage here. I wold hope you are protecting accounts and files with appropriate file permissions. You are right about this. But, theoretically, it is still easier to steal a folder than a DB. If you have complicated searches over a lot of data then yes, a data base is appropriate. I didn't say it was never the way to go. But - I would take issue with this statement. a little search on a few variables is almost always going to be faster in a flat file unless you are refering to finding a few records based on a key. If you ever write files, then at least write PHP files that can be simply included and referred by array keys. Then yes - files are faster. But, if data is big than not. Database is also portable, and portability is VERY important in programming. Conclusion: 1. Flat files - for site configurations 2. Database - for data manipulations Databases are suitable for situations where you have a large amount of complex data that you must do complex operations on. The trade off will be the extra maintenace you must do and the additional potential points of failure you must contend with. But truly, the one that knows to handle files well normally has no problems writing SQL either and/or keeping a DB server up. Be
[PHP-DB] loading includes
Here's one that will shake your head, mine's about shook off. Basic problem: new site works on my box but not on dev server. Both boxes have Apache and php loaded. New site is not loading includes and dynamic data. The old site copy on dev server has some main pages that include some files when loaded and loads some dynamic data from a database. I'll call one of the main pages pgroups. When old pgroups gets loaded on dev server, included files are included fine and data gets loaded. When I ftp over my modified pgroups - files are not included nor does data get loaded. The modifications are small in number, but basically add a javascript menu to pgroup and some layers in an included file. I've tried commenting out the javascript code in pgroup but it still wont add header.php which has meta tag info, plus other include file info that does load with old script. Done some other error checking to basically prove that the include files are not being included on dev server. I have also tried including the absolute path when calling the include, which is in the same directory as pgroup anyway Additionally, on my box, all of the new files work fine. All the includes get loaded and dynamic data gets loaded. *** my box - only thing in php.ini is register globals = ON *** dev server - php.ini include path is commented out. But old code gets loaded fine. This code was loaded and configured by someone else that got it from phpnuke for free. Lucky me. We would start from scratch but have 11/1 deadline. I can send each page of code, pgroup.old pgroup.new, both are about 3 pages long. I think we're not supposed to send attachments ? I cant remember. Both boxes have Apache 1.3 and am assuming php 4 on both. -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP-DB] mysql_affected_cols() ??? or equivalent?
Is it possible to find out how many columns from a row were updated in a
single update SQL command?
For example:
$x = mysql_query(update users set un={$un},pw={$pw},ln={$ln},fn={$fn} where
id={$id});
And the function (something like mysql_affected_cols()) would return 0 if
everything stayed the same (like mysql_affected_rows() does), or if
something changed, the number of columns that were changed.
So if only the password and first name were changed, mysql_affected_cols()
would return 2.
From PHP.net regarding mysql_affected_rows():
When using UPDATE, MySQL will not update columns where the new value is
the same as the old value. This creates the possiblity that
mysql_affected_rows() may not actually equal the number of rows matched,
only the number of rows that were literally affected by the query.
Any ideas?
Peter

RE: [PHP-DB] PHP and databases? ...without MySQL and such
PHP-nites, I want to thank you all for your insight on PHP and database options, particularly to FLAT FILES. Many of you commented on using MySQL or Oracle and such, commenting how better it would be. I STRONGLY agree that using MySQL or any DMBS database application is a FAR better options. Although I am in a situation where I can only use FLAT FILE databases. I know it is not the best solution, but better than no database at all. I have looked into your suggestions on using dbase_create, php_dbase.dll, dbm, dba, xml, com and such, yet without finding a real solution. So, I am developing my own custom functions to maintain FLAT FILE databases. - EXAMPLES: - $conf_array = _FILEDB::Open( '/data/file.txt' ); _FILEDB::Edit( $conf_array, $line_id, $header, $new_value ); _FILEDB::Search( $conf_array, 'LIKE', 'joh*' ); _FILEDB::SearchHeader( $conf_array, 'LIKE', 'FNAME', 'John' ); Well, when I get done I'll post a link to download it for free. I know everyone is PRO MySQL, so am I. I just think flat files should not be excluded. Again, thank you all for your help.

A former programmer of mine who worked for a Security firm developed the base-line code which was originally written in C then transferred into Perl. He was greatful enough to provide us with the code (which is quite small) while working a few site before his departure. Seems to works like a charm and we've never had any issues with it (hacking, etc).

RE: [PHP-DB] Credit Card Info Cryptography
Since your goal is to encrypt the card number in the database you'll naturally need a way to decrypt it as well. At that point it seems your concern is that your database will be compromised. That can be avoided easily by creating a single private key and using your own algorithm to encrypt based on that key. The only catch is, if the code that does the encrypting is compromised, and the database is compromised, then the numbers are compromised. My basic point is, your need is not the same as what PGP addresses in that PGP addresses the more difficult problem of passing data between 2 entities. Your requirement is very simple to address; 1. write a simple compiled module with an embedded key, 2. keep that key in a safe place, and 3. write another module to decrypt, all it needs is the key. This is similar to what was done with DVDs, just don't allow your encryption algorithms to be compromised. You can put the source code in the same place as your key, you can use a code scrambler when you compile, and you should already have your server secure already. Again, my point is, this is easy because the same entity that encrypts is doing the decrypt. Hope this helps.

RE: [PHP-DB] Credit Card Info Cryptography
OFFTOPIC :-) You have a good point, I just assumed that decision had already been made. Here's :a visual representation of my point. To hide A by turning it into B using algorithm object C and only someone with key D can see it. C.encrypt(A,D) = B; C.decrypt(B,D) = A; If anyone has either part of C, or D you can consider your data compromised. However, a reasonably complex C and D will result in a B that will not be useful alone. In the case of PGP the encrypt and decrypt algorithms are public, either of which are a good start to breaking the encryption. Hence the considerable increase in complexity of their problem the need for a more complex solution. Every encryption method by nature boils down to obscurity. What cannot be kept private must be complex enough to provide sufficient security. Hence the name P(retty) G(ood) P(rivacy) ... Which is better, 128 bit encryption or 40? If you answered 128 you are correct, only because it introduces more complexity than the other. Trivia Question: Why WAS it illegal to export strong encryption technology? Answer: Export laws? Technically, but specifically the government wanted the ability to decrypt exported data in a timely fashion. You can believe it... or not. /OFFTOPIC I LOVE PHP!!!

RE: [PHP-DB] Credit Card Info Cryptography
How about encrypting the credit card with a secret word that the user chooses? Or obsfucate it by encrypting their credit card using str_rot13(base64_encode(str_rot13($lastname).$lastname.$email.$firstname)) as the key? Sure, if someone gets your code and your DB, those credit card numbers are as good as gone. But what about using a C program, stripped, doing the same thing? That way even if they get your PHP code AND the C program, they won't be able to reverse engineer the code. They can, however, start plugging in strings into the C program (if they have the same system you have, binary compatibility and all) and try those outputted strings on the DB. Let's all agree though: there is no 100% sure way to protect any data if you are going to be able to decrypt it. There are ways, however, to make it tough to do so for the average hacker. I mean, if Hacker A wants your credit cards, you can't keep the key from them. You have to use it somehow to encrypt it, and assuming this happens in the code and not manually, it is located somewhere on your site. If they can get the DB, they can get the key. Obsfucation always worked for me. Peter On Wed, 23 Oct 2002, Aaron Wolski wrote: Maybe you do, Bt I run a _client_dictates_the_development_requirments business.

You probably reached the number of persistent connections configured in php.ini . If you allow a larger number you probably exhaust your server memory until it crashes. The best solution is to cache content taken from the database and that does not vary frequently. That will also make your site faster. In that case you may want to try this class that can be used to store arbitrary data in files, like the HTML excerpts that are generated from your database queries. http://www.phpclasses.org/filecacheclass -- Regards, Manuel Lemos -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP-DB] checking data from a flash movie at my domain for an insert
is it possible to make sure data that will be inserted into a database is from a flash movie ( a game) residing on my domain? The data will be linked to prizes, so I want to be able to make sure that nobody executes a script and provides false data. The security measures I have now are encrypting strings client side (flash) and decrypting server side (php), only sending post vars, and sending obscure variables hidden deep in the flash movie, plus checking for the right ( or emtpy) value of http_referrer and checking for a cookie var that is set in the php page that embeds flash. So it's an I'll-make-it-annoying-but-not-impossible kind of thing. The reason I'm asking is because flash movies can be decompioled so the algorithm for encrypting can be decoded easily. thanks -- Rolf Vreijdenberger De Pannekoek en De Kale Maystraat 6 2593 VW Den Haag T: 06-24245719 E: [EMAIL PROTECTED] W: www.depannekoekendekale.nl -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP-DB] Credit Card Info Cryptography
There is a simple alternative that you might not be aware of, and that is use Advantage Database (I am assuming that you are using MySQL right now). You can get a free version to try and it provides encryption at the table level. There is a PHP interface for it and everything can be found at www advantage-database.com and go the the developers download area. I have been using it in my everyday development for about 4 years and I love it. I just recently saw that they offer a PHP interface to it as well as an ODBC, VB, Delphi, C++ Builder, JBuilder etc. Store the credit card info in Advantage and leave the rest of your data where you have it.

I mean when i'm using frames they appear or like a view with scrollbar or there is an option to print them singulary.

The printer functions in the manual only work in windows and only work for the printer attached directly to the server. Hmm..I wonder, though, if you have a network printer that's set up to print from the server, can you use the printer functions to print to that? I'm sure the answer is in the manual. If not, maybe you can open a connection directly to the printer and send it the raw data, if you know the format. ---John Holmes... -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php Free Email Account at www.flash.ro -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
