Re: [PHP-DB] Closing curly brackets?
a good tutorial for code formating is c and c++ style guides
( http://www.cs.umd.edu/users/cml/cstyle/ )
a good code editor is vim (http://www.vim.org).
Jennifer Downey a écrit :
Thank you Paul,
I have asked about atutorial on proper code formatting and got back a
tutorial that was extremely hard to understand. While lots of people have
screamed at me for my coding format no one has supplied an understandable
answer. That is until this morning.
The first thing you should do is properly indent your code. If you do so,
you'll be sure to find the missing bracket. Basically, for each new
block,
tab out again.
Thought that was the best tutorial I could ever get. Short and sweet and oh
so easy to understand.
I am using HTML_Kit as it has the same features as all the othere editors
(color coding and such) but it also has a lot more. I can get plugins for
anything I would ever need. Except a formatting tutorial ;)
Thank for your help

Hi Jennifer,
The first thing you should do is properly indent your code. If you do so,
you'll be sure to find the missing bracket. Basically, for each new
block,
tab out again. It really helps to use a programmer's editor with syntax
highlighting like vim or BBEdit. Here's an example using your code:
===
$id = $HTTP_GET_VARS[id];
$query = SELECT id, name, image, quantity, type FROM
{$config[prefix]}_my_items WHERE uid={$session[uid]} ORDER BY id;
$ret = mysql_query($query);
while($row = mysql_fetch_array($ret)) {
$iid = $row['id'];
$image = $row['image'];
$name = $row['name'];
$quantity = $row['quantity'];
$type = $row['type'];
if ($iid == $id) {
$display_block =CENTERimg src=$image border=0brfont
size=2$nameBR$quantityBR$type/font/CENTER;
echo $display_blockBRBR;
if ($type == food) {
//if book or weapon is present then set an option and include
in
the form later
$thisoption=OPTION VALUE=\feed\Feed my pet\n/OPTION;
} else {
//if any other type is present then set a blank
$thisoption=;}
} // end option if statement
} // end id if statement
/* More code after this point */
} // end while if statement.
===
Hope that helps.

How about:

while (list ($key, $val) = each($test)) {
if ($key == 0 || $key == 3) {
//do nothing
} else {
echo $key = $val;

Let me know if this works.

Hmm, I have also been having similar problems with LOBs. However it

not
be cursor_sharing=force, because on my Win 2000 oracle, LOBs work fine
with
PHP
with this parameter set.
However on our Sun server, PHP crashes as you mention (yes
cursor_sharing=force is
set here too).

Is there any work-around for this? Is this a bug? This seems to be

[PHP-DB] Re: Delete from mysql table is there a way to....
I'm not sure how to change DELETE statements in this fashion, but is there a
way maybe to run an OPTIMIZE TABLE query every so often in your PHP script..
I don't imagine you'd want it running too often since it locks the table you
run it on, but maybe on the reload of $PHP_SELF or something.. It can take a
while to run on tables with lots of data, so it may not be the best option
anyway.. Just a thought though.. Ooh, maybe a PHP script run from a cron job
every couple hours or something even??

This is purely a MySQL issue. Is there a way to delete a record from a mysql table without fragmenting the db?

[PHP-DB] Re: Delete from mysql table is there a way to....
Maybe if you ran the delete query, then the optimize table query immed
after, it wouldn't take such a long time.. I would imagine if you had quite
large tables though, it could still take some time.. And if users are
connecting over the internet, you don't want too may delays..
If the user doesn't need any specific feedback about the delete command, you
could do a low priority delete.. That's sketchy at best though from what I
could gather in the manual and around. It just queues the query until the
database is done with everything but it sounds like it might release the
user/client to go on with what they're doing..
You might also check into truncate.. The mysql manual talks about it
briefly.. I guess it's an Oracle thing that mysql supports.. It sounds like
it would keep things clean but sounds slow possibly..

RE: [PHP-DB] Cross DB application
Hi Arcadius, If you know Object-oriented programming , you can write a class that includes both MySQL and PostGreSQL functions and you can inherit from that class. Or, you can just stick all mysql, postgresql functions in a functions.php file and include that file to be able to use the functions. I guess it would work best if you have a configuration file where the user chooses either DB and your code uses the corresponding function for that database. I am sure there are database wrapper classes for php to address your issue somewhere on the net , I just don't know where, since i have never searched for it.

Your $eventdate variable is an array, not a string so you can't just
drop it into an sql query string like that.
If you have separate fields in the db for year, month and day then you
probably want something like:
$query = insert into ... values ( ... , '$eventdate[0]',
'$eventdate[1]', '$eventdate[2]', ...);
Otherwise, if they're all supposed to go into the same field then do
something like:
$eventdatestring = join(-, $eventdate);
$query = insert into ... values ( ..., '$eventdatestring', ...);
This should insert the date in the form eventyear-eventmonth-eventday;

Hello, Arcadius A. wrote: Hello ! I'm planning to write a database application for MySQL, and then port it to PostrgeSQL. Is there any library or class that could help me to write/maintain just one source code for both MySQL and PostgreSQL ? I think your best (if not the only) option in PHP is Metabase. http://www.phpclasses.org/metabase This is a PHP databases abstraction focused on application portability. AFAIK, it is the only one that provide complete and true data type abstraction. This means that for instance if you have to deal with dates in your application, Metabase assures that you only have to deal with a single date format (ISO 9601 - -MM-DD HH:MM:SS) even if the underlying databases use other formats. So, when you switch to a different database, you do not have to touch a single thing in your application other that the choice of database type option. Metabase goes farther, it also abstracts database schema installation and maintenance. This means that it provides a way to describe a schema of database tables, fields, indexes and sequences using a simple XML syntax. Then the Metabase manager class will install it for you in the target database that you use. If you move to another database, Metabase can export the database contents in the same XML format and then you may reinstall the schema in the new database type without loosing information. Here it is an example of a Metabase schema: http://www.phpclasses.org/browse.html/file/59.html Regards, Manuel Lemos -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

According to Thies, this is an Oracle bug. A quick workaround which I just
tested is to execute an alter session before updating the LOB, and restore
cursor_sharing=force after the update.
ALTER SESSION SET cursor_sharing=exact

John!
Thanks for the update. Did you find any work-around for this issue?
Thanks,
Prince.

Hmm, I have also been having similar problems with LOBs. However it
might
not
be cursor_sharing=force, because on my Win 2000 oracle, LOBs work fine
with
PHP
with this parameter set.
However on our Sun server, PHP crashes as you mention (yes
cursor_sharing=force is
set here too).
PS: this is set in init.ora.

I have the following php code. If I add the parameter
CURSOR_SHARING=FORCE
in my init.ora and while executing the program I get the
Segmentation
fault.
$ /usr/local/php4/bin/php -q curshare.php
Segmentation fault (core dumped)
Is there any work-around for this? Is this a bug? This seems to be
happening
only when LOB with returning clause is present.
I tested a similar program from C program and is fine.
Note: currently I have set the parameter (CURSOR_SHARING=FORCE )
only
in
the program/session level.
Thanks,
Prince.
$ cat curshare.php
#!/usr/local/php4/bin/php -q
?
//program name curshare.php
$conn = OCILogon($dbuser, $dbpass, $dbname);
//This is added to affect only the current session.
$sql = alter session set cursor_sharing=force;
$stmt = ociparse($conn,$sql);
OCIExecute($stmt,OCI_DEFAULT);
$lob = OCINewDescriptor($conn, OCI_D_LOB);
$sqlstmt = insert into blob_test ( packageid, packagebody )
values('12344321123efd', EMPTY_BLOB()) returning packagebody into
:packagebody;
$stmt = OCIParse($conn, $sqlstmt) ;
OCIBindByName($stmt, ':packagebody', $lob, -1, OCI_B_BLOB);
OCIExecute($stmt, OCI_DEFAULT);
OCICommit($conn);
OCIFreeDesc($lob);
OCIFreeStatement($stmt);
OCILogoff($conn);

Re: [PHP-DB] Cross DB application
Hello, Andrew Hill wrote: ARcadius, You may use an abstraction library such as PEARDB or ADODB, or simply the unified ODBC functions. Andrew, you always suggest ODBC as a good solution for portable database application development, but AFAIK it is not a good solution at all because for crucial things you still have to resort to database specific code to handle database differences. I already asked you this before but I don't recall ever getting a satisfactory answer. I don't know if the problem is in PHP ODBC API or is really an ODBC limitation, but for instance, when you want to implement auto-incremented sequences of integer values that are fundamental for database aplications to use in primary key fields, with ODBC you there seems to be no database independent way to create and retrieve the next sequence value. The other important issue, especially for Web development, is query results paging. In most current databases there some clause like for instance MySQL LIMIT. Others use different syntaxes or clause for restricting the range of rows that are returned by the server to the client. This is importa, especially when you want to show a small number of rows of a very large result set. Once you suggested to use ODBC cursors, but that is not the same as limiting the result rows in the actual queries. For instance, if you need to get the first from row 10 to 19 of a result set of 1.000.000 rows, using the LIMIT clause will make the server stop the query after 20 rows. Using cursors, AFAIK will not stop the query making the database server hog the machine needlessly to traverse 1.000.000 rows of data that an application is not interested in. I don't know if there are better and portable solutions using PHP ODBC API functions, but with your ODBC knowledge is there a way to solve these issues with a complete ODBC API (besides what PHP ODBC API can offer)? I would like to make a better ODBC driver class for Metabase so users can develop portable database applications using Metabase via ODBC, but it seems that I will have to develop subclasses for each type of ODBC data source (MS Access, IBM DB2, SAP-DB, etc...) to handle database specific issues that the ODBC API does not handle by itself.

[PHP-DB] Re: [PHP] Re: Cross DB application
Hello, James Cox wrote: I'm planning to write a database application for MySQL, and then port it to PostrgeSQL. Is there any library or class that could help me to write/maintain just one source code for both MySQL and PostgreSQL ? I think your best (if not the only) option in PHP is Metabase. http://www.phpclasses.org/metabase snip spam you could also use PEAR (http://pear.php.net/) which has a more than adequate abstraction layer for various databases. PEAR does not offer a good means of writing portable database applications because it does not have data type abstraction support. This is important because different databases represent data types differently. For instance, Oracle, unlike other databases, does not have individual time and date field types, only a single type that represents both a full timestamp with time and date. This means that if you just want to store a date on the field you have to use the whole timestamp field and discard the time part. Metabase handles that for you. PEAR does not provide any support for this level of database portability. I think this is an important point to mention about this limitatation of PEAR because I noticed that a lot of people that use PEAR did not know about it because they develop applications that only deal with text and integers that need little or no conversion, besides any eventual quoting. As soon they need to use other data types like date and time, when they need to run their applications in different databases, they realize that PEAR was not a good idea because, unlike Metabase, it doesn't handle datatype representation format differences. This may not be a problem for you James, but it is a problem for a lot of database developers that really care about portability because it costs a lot of time and money to maintain the applications that need to work with different databases if you have to tweak your application to handle the differences of the databases. This is the main reason why Java JDBC provide such an high level of database application portability, that in the PHP world only has parallel with Metabase. But, I doubt even metabase can rewrite your SQL queries for you so that it's optimized for postgres AND mysql (and any other option you would like to choose). Metabase does not rewrite queries. You need to know Metabase better. It just converts datatypes of between a database independent format that applications use and the native database datatype format, if and when the develop wants that. you're much better off either picking one DB system, or use both but maintain seperate SQL for each, to provide full optimization. If the original poster would not mind to have the major headache of doing that, he would not have posted, don't you think?

[PHP-DB] Definitive answer for large scale registration/authentication
Can I get some feedback on the conventional wisdom as to the best solution for high volume registration and authentication of users accessing a secure site?

Probably the fastest way to keep session profile information is by serializing the data array into a string that will be encrypted and then stored in cookie. The security weakness of this method is that if the secret key leaks, hackers may use to forge new sessions. A more secure but eventually less scalable method is to store the session data in a shared memory cache, so you minimize database accesses to just one after the server is restarted. This is probably the one you want to use as long you know how to deal with shared memory and semaphores.

I guess you mean HTTP based authentication. No, AFAIK that is very unsecure because you can't end a session because browsers cache authenticated passwords and only drop them (of they do, IE may not do it) when you quit your browser.

[PHP-DB] Re: database table layout help
In article [EMAIL PROTECTED], [EMAIL PROTECTED] says... I am setting up a music info site and have decided on the follow tables ( not to sure weather to add the mp3 part). The one main question I have before starting to make the tables is weather mysql_insert_id() would be able to handle this with the way I have it ? :Artist id artist_name :Album id - auto-inc artist_id album_name rec_id image_id :Songs id - auto-inc album_id genre_id mp3_id lyrics :Genre id - auto-inc genre :Recording id - auto-inc recording_studio date :Album Image id - auto-inc image :Artist Info id - auto-inc info :Mp3 id - auto-inc mp3_location Any other suggestions are welcome. B.J.Rumsey In answer to your specific question, yes, mysql_insert_id will work for you as you have auto-increment fileds on each table. In passing, you could probably combine your artist and artist_info into one table - assuming there will only be one 'info' for each artist. Similarly, album and album_image could be combined. I don't see a song title field? Is that deliberate, or did you miss that (or am I blind?) -- David Robley Temporary Kiwi!

Re: [PHP-DB] Delete from mysql table is there a way to....
What exactly does it mean when a table becomes fragmented? How do you know
when it's happened and something should be done? All the docs and books
talk about how bad it is but I'm still confused on what this is and when it
happens.
Thanks,

Here is the query I am using and it does a horrible job. Fragment city.

}
