[PHP-DB] Using MySQL Inno DB transaction
Lately i'm building a library automation application with php 5 and MySQL 4..1. For the transaction module, i'm using Inno DB engine to store the transaction data, cos i want to use MySQL transaction method which can be commit or rollback. But when i tried to rollback the transaction in the other script, the data still exist in the database. script1.php : ?php $mysqli = new mysqli(...); $mysqli-autocommit(false); // do the transaction // and process it in script2.php ? script2.php ?php $mysqli-rollback(); ? What's wrong?? does anybody could help me?? Thanks -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

RE: [PHP-DB] PDF encoded
Hi Bastien.
Snippet of my code is
header('Content-type: application/pdf');
header( Content-Disposition: inline);
header('Content-Transfer-Encoding: base64');
echo echo base64_decode€($String);
Where
$string contains the encoded string.
Don’t know where I am going wrong.

Shekhar

Re: [PHP-DB] PDF encoded
Looks like you're telling the browser that the data is base64, and then
decoding the data before you send it.
Try sending the string without the base64_decode() statement. just echo
$string
Or, lose the transfer encoding header, and leave the base64_decode() in..

Re: [PHP-DB] PHP Bug handling Messages from MSSQL ?
Hi Denio, The function name should say it all, mssql_get_last_message() returns the last and only the last message from the server. I'll add an item on my todo list to implement a mssql_get_server_messages() function tal will allow you to get all messages from the previous mssql_query() call. This will only be available in PHP 5 as PHP 4 is closed for new features. - Frank Hello, I'm trying to build a demo of SQL Injection (SI) to discuss with my students. The idea is to use the live demo to show and discuss how to avoid SI using some secure code techiques. I'm using PHP 4.3.11 and MSSQL 80 on a windows XP box. Sometimes a multiline query is submitted to the server, something like this: use sales; select name from users; drop table xxx; Note the query above has in fact three queries, each one producing a message but the function mssql_get_last_message() aparently doesn't return all of them to the user. Capturing the packets during the connection (e.g ethereal or tcpdump) I can perfectly see all messages returning from the server, like this: --- (1) Changed database context to 'sales' (2) result set here (3) Cannot drop the table 'xxx', because it does not exist in the system catalog. But only the first message is returned from PHP mssql_get_last_message(). Can anyone help me to explain this behavior ? Thanks in advance. Denio. ...

Re: [PHP-DB] PDF encoded
I didn't really read your post carefully. On second read it looks like you're
trying inlide embedding? So in other words, you want an HTML page with an are
that is a PDF, as if you used an embed tag?
If that's what you're trying, it's really flaky, and you'd be better off to
save it as a .pdf file, and use the embed tag, IMHO..

[PHP-DB] PDO name
Anyone know why the name PDO was chosen for what is really just a SQL abstraction layer? I actually implemented something a while back that I called PDO, which provided a means to do get/set/save/delete etc. operations, on data objects, but the persistent implementation was hidden from the application programmer, similar to JDO. It seems like PDO is a misnomer, and there is a need for a real PDO framework... -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP-DB] Creating an Interbase.so file
I am running Fedora Core 3 and I want to install and integrate Interbase (Firebird 1.5) with php. To create the so file, I downloaded php 4.4.0 and did a ./configure --with-interbase=shared,/opt/firebird make Then I place the interbase.so into /usr/lib/php4 and make an interbase.ini in /etc/php.d to load the interbase.so. When I do a restart of httpd, I get this error: PHP Warning: Unknown(): Unable to load dynamic library '/usr/lib/php4/interbase.so' - /usr/lib/php4/interbase.so: failed to map segment from shared object: Permission denied in Unknown on line 0 Any suggestions?

[PHP-DB] Searchable/Sortable Database Fields with MySQL/PHP
Greetings, I need to securely store lots of sensitive contact information and notes in a (MySQL or other freely available) database that will be stored on a database server which I do not have direct access to. This database will be accessed by a PHP application that I am developing. However, I also need to be able to search/sort these data with the database functions (SELECT, ORDER BY, etc) so simple PASSWORD style encryption of specific fields would not work. (For example, I need to encrypt contacts' names, but need to be able to sort results by name). (I realize I could load the entire table into memory with PHP and process/search/sort it there, but that's obviously not a very good solution). Ideally I would like to encrypt entire tables. An encrypted file system is not really an option, because the goal is to prevent loss if the database server is hacked (in addition, I wouldn't be able to install an encrypted file system on the database server). My sense is that this is a difficult problem. However, I made the mistake of promising this functionality, so I'm scrambling to figure out some kind of solution. Any suggestions? Thanks so much!

Re: [PHP-DB] Searchable/Sortable Database Fields with MySQL/PHP
Just do all your searching/sorting in PHP.. it would be slower, and if your dataset is very large (sounds like it might be the case) it would be impossible.. So that might be out of the question.. A bit of system engineering might find a solution too, consider which fields you need to search/sort by, and by possibly limiting those somewhat to just what is absolutely necessary, you might be able to get by not encrypting those columns. Another idea would be to provide hinting columns, essentially providing just enough data in those columns to be able to sort with, but not enough to give away the data. i.e. just the first 2 characters of each name. This would allow you to search and get a smaller dataset from the database, something you could decrypt in php, and then search further, possibly making it manageable. Hope that helps, -Micah On Tuesday 12 July 2005 2:36 pm, Matt McNeil wrote: Greetings, I need to securely store lots of sensitive contact information and notes in a (MySQL or other freely available) database that will be stored on a database server which I do not have direct access to.

Re: [PHP-DB] Searchable/Sortable Database Fields with MySQL/PHP
Oh! Also, there's built in mysql functions for encryption, I forgot about
that, so you can still search, like this:
insert into table set name_field = AES_ENCRYPT('Some name', 'secret key');
select * from table where AES_DECRYPT(name_field,'secret key') LIKE '%some';
Make sense? You'll want an SSL connection to the database of course, and
anyone that has any decent access to the server memory would be able to get
the encryption key, but if you're careful it would work.
