Re: [PHP-DB] Sorting in numerical order, and then randomly
Hi Peter,
Thanks for the suggestion, suggestion 3 works perfectly if I also switch
the order of the numbering as you suggest, because then I can do order by
priority desc, rand(), which returns the numbers first and then the 0's,
which is what I really wanted. Also, good point about adding higher
priority advertisers - I hadn't thought of that.
Thanks again,

Your options, as I see them, with 3 being the best I could come up with:
1. Make two queries. Depending on how many rows returned, this may be
the less taxing option processor wise.
2. Make the random query. As you iterate through them push folks with
priority 0 on one stack, priority 1 another stack, etc. At the end
of it all you'll have a bunch of stacks with a randomly ordered list
of advertisers.
3. (This is the obvious winner)
select * from ads_value where status='current' order by priority
asc, rand()
This will return 0's first, 1,2,3... etc after that in a random
order. I might recommend re-ordering your priority making 100 the
highest and 1 the lowest priority above 0. This way if you get an
advertiser that beats everyone out, they can be 101 or 150 or (if
you are lucky in this market) 2000. If you do it your way (as I
understand it) you will have to bump down #1 to #2, #2 to #3, etc in
order to put a newer higher priority advertiser first.

Ads for which advertisers pay more will have a higher priority - i.e. 1, 2,
3, etc. Everything else will have a priority of 0. When the page loads, I
want to first display any ads that have a priority higher than 0 to be
displayed in order, and then the remaining ads with a priority if 0 to be
displayed in random order. They have to be displayed in a different order
each time, so that each ad has the same chance of being displayed in a
particular spot as any other ad. The only spots a random ad cannot be in is
one taken by a higher paying ad. I hope this is clear.
Is it possible to do this with one query? Or would I have to use 2
different queries:
select * from ads_value where status = 'current' and priority 0 order by
priority asc
and then
select * from ads_value where status = 'current' and priority = 0 order by
RAND()

RE: [PHP-DB] Passing by reference
Rasmus,
Peter and I were discussing the use of .$myvar. vs quoted string {$myvar}
more quoted string in a separate thread.
Is there a performance or compatibility advantage to using the concatenated
version as you suggest in your message below?
I currently use the concatenated version in all of my scripts, but Peter
suggested the curly braces as a way to make the code more readable. While I
agree that the curly brace method IS more readable, I want to know what the
difference is before changing coding conventions.
Thanks,
Rich

Subject: Re: [PHP-DB] Passing by reference
PHP uses copy-on-write for by-value passes. So, if you are
not changing
the passed string inside the function there is no copy done on a
pass-by-value and this is actually faster than doing a
pass-by-reference.
But, I'd suggest doing .$myvar. (ie. break out of the
quoted string and
concat the var.)

passing by reference, not copying:

A few questions:
1. Am I correct that PHP makes a copy of the variable
when I call the

be global in
the function (unless I declare it such)?
2. Will I be saving some CPU cycles and memory by
passing by reference?
3. Is my pseudo code above correct? If not, can you
show me how one
might pass by reference correctly?
I've tested both pieces of code, but can't determine if there is a
speed/memory difference, and I don't actually have 125K in
data handy!

[PHP-DB] Fastest, easiest Flatfile DB with PHP

Re: [PHP-DB] Fastest, easiest Flatfile DB with PHP
For massive amounts of data, you really want to use some type of SQL database. Not only will you save time programming, but massive server resources aswell since the disk doesn't have to parse and seek a large flatfile everytime.

Re: [PHP-DB] Fastest, easiest Flatfile DB with PHP
For one, I don't see how it would be beneficial to store large quantities of data in a non-database type of format. As far as reducing the overhead of using MySQL, there are many methods one can use to reduce the number of queries to a database. For instance, if you are worried about making many small queries, you might want to look into creating large arrays of data from few queries, and then breaking out those arrays into the pieces you need throughout your program. I just revamped some code I did a while back and did the very same thing, making one db call to create a big array, and passing sections of that array that I had broken into multi-dimensional arrays to various functions. This change cut the processing time in half. Another option is using reduced data sets for certain tasks, if you can tell from the beginning of the program that only certain groups of data will be needed, such as per date entered, age, etc. | John Krewson | | 865-974-3263 | | [EMAIL PROTECTED]| |Senior Programmer/Analyst | Social Work Office of Research and Public Service The true art of memory is the art of attention.

RE: [PHP-DB] Fastest, easiest Flatfile DB with PHP
I've read the other posts and agree with them wholeheartedly - sounds like you actually should investigate using some sort of relational db, MySQL or otherwise. However, if there is some major reason you don't or can't use a relational database, you may want to consider storing your flat files as XML and using a native XML database to store and query those documents. Tamino by SoftwareAG comes to mind. It's proprietary, expensive and I don't know if or how you'd blend PHP with it, but if you absolutely must use flat files, XML might help. If you can get your head around XQuery (not an approved standard yet: http://www.w3.org/TR/xquery/) then you might be able to stay away from a proprietary solution like Tamino and use PHP to manipulate the flat files and possibly MySQL to store metadata if you need it(?). Don't know, just rambling at this point.

Valentina is rather unusual, coming as it does from its origins as an embedded SQL database for things like Macromedia Director and RealBasic, but it's maturing very nicely and is also available for Java, VB, C++ and several other environments. In OO environments (like RealBasic C++) it has an OO API which is just great. I already get speeds out of it well beyond what I can get with MySQL, and it has a more useful SQL environment (foreign keys etc). I recently built an essentially flat file with 20 million records recently and I easily get searches in under 0.1 sec in Director (which is a slow environment) on a P3/600 where the DB was 2x the size of available RAM, and it has at least an order of magnitude improvement in development. As yet it isn't client/server (will be in 2.0), but for the kind of solution being discussed, it's really excellent, especially as it will be running as a PHP extension, rather than as a separate server.

This works great :-) Thanks.
I'll write a letter to onlamp.com to get that misleading code off their
website (maybe it's PHP3 based?).
Perhaps this should be added to PEAR? It appears that this is the
proper repository for such things. I'll look into it although I would
be much obliged if somebody in the know could handle this since I am new
to PHP.
One thing I left out - I had to take out the $GLOBALS[acdb] part from
mysql_query. This doesn't work with my version of php (4.2.3) I guess.
Also, assert(!empty($SessionTableName)); didn't work, so I commented it

[PHP-DB] Insert path string into Mysql
Hi,
I have the following code, but it doesn't works. How can I insert a path
string into a MySql Varchar cell? The result is always FALSE, but if $path
is a normal string ($path ='demo') than it works fine.
What can I do? (I use WInXp, Apache, and Php4.2.2)
Thanks!
?php
$database=PH;
mysql_connect(localhost,root,);
@mysql_select_db($database) or die( Unable to select database);
$path = 'c:\\demo\\' ;
$query = insert into PH_PHOTO (PHOTO_PATH) VALUES ('$path');
$result=mysql_query($query);
mysql_close();
?

I would guess that the backslashes are being interpreted once by php
when the variable $path is interpolated into the query string (to
become c:\demo\) and again by mysql at which point it tries to insert a
value for \d. You might try $path = 'c:demo' and see if that
works. Or maybe leave the path alone and do the query line like this:
$query = insert into PH_PHOTO (PHOTO_PATH) VALUES (' . $path . ');

You might also want to look into using addslashes($path), especially if
you're going to be accepting this path info from a text box.

However, if there is some major reason you don't or can't use a relational database, you may want to consider storing your flat files as XML and using a native XML database to store and query those documents. Tamino by SoftwareAG comes to mind. It's proprietary, expensive and I don't know if or how you'd blend PHP with it, but if you absolutely must use flat files, XML might help. If you can get your head around XQuery (not an approved standard yet: http://www.w3.org/TR/xquery/) then you might be able to stay away from a proprietary solution like Tamino and use PHP to manipulate the flat files and possibly MySQL to store metadata if you need it(?).

[PHP-DB] creating a new mysql automatically every day?
i'm currently building a traffic analysis application for a website. it is my first time working on such a project, so i'm not even sure if this would be the best way to do it all, but here it goes. what i would like to do is count the number of hits that go to different sections of the site. i can think of two ways of doing this, although i'm not sure what would be the most efficient. option 1- i already have a table thast records each session on the site (including browser type, time they entered site, referring page, etc). on this, i could think of adding a field for each section of the site i wish to log, and simply implement a counter each time they visit a certain section. then when i wanted to analyze it i could use the mySQL sum() functions. (because i'm really only interested in how many total visits to each section, not who went where exactly). option 2- having another table with a new row being created daily, and fields with a counter for each section. then i would have the problem of automatically creating a row each day at midnight though. my other question is i'm worried about database size. i've been reading posts on this board about mySQL goin to hell with over a million records. this table is definitely going to eventually grow pretty large, but it wond be accessed all that much (as it would just be for traffic analysis for the two site admins every now and then). should i be worried? thanks -jon -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
RE: [PHP-DB] creating a new mysql automatically every day?
Not sure what the best answer is, but if you are going to have a table that's mostly going to be inserted into, and rarely read, then don't create any indexes or keys on it. When it comes time to search the table, copy it to another table, create indexes, and search away. Indexes slow down inserts. ---John Holmes... -Original Message- From: Jonathan Narong [mailto:[EMAIL PROTECTED]] Sent: Monday, November 18, 2002 8:26 PM To: [EMAIL PROTECTED] Subject: [PHP-DB] creating a new mysql automatically every day? i'm currently building a traffic analysis application for a website. it is my first time working on such a project, so i'm not even sure if this would be the best way to do it all, but here it goes. what i would like to do is count the number of hits that go to different sections of the site. i can think of two ways of doing this, although i'm not sure what would be the most efficient. option 1- i already have a table thast records each session on the site (including browser type, time they entered site, referring page, etc). on this, i could think of adding a field for each section of the site i wish to log, and simply implement a counter each time they visit a certain section. then when i wanted to analyze it i could use the mySQL sum() functions.

John, That is good advice. I wasn't aware of indexes/keys slowing down inserts. Whats the best way to copy a table over to another table though? -jon -Original Message- From: John W.

Re: [PHP-DB] If conditional behaviour
If you develop the habit of writing conditionals like this:
if (Victoria == $city)
instead of like this:
if ($city == Victoria)
Your compiler (interpreter in PHP's case) will catch the assignment
vs. comparison error for you, because assigning to $city is valid but
assigning to a constant string Victoria isn't. Of course you'd
have to have display_errors On for PHP to report the problem

That was it.
How embarrassing.
Thanks!

Did you try $city==Victoria ?

isn't set up on the server, so I've posted a screenshot of what it
looks like at http://crockett.ca/joinoptionalrendered.bmp (1/2 MB,
sorry). For some reason, it wants to repeat 'Victoria' in the form.
If I comment out the If conditional:
// if ($city = Victoria) {
// Ýecho selected ;
// }
..the problem goes away and the different cities appear as
expected.
The result of the query is at http://crockett.ca/queryresults.txt
Can someone point me in the right direction?

$encrypted_string = md5(base64_encode($var.'secret key')); Pass the user name or password to $var and place text in to replace the words 'secret key'. -Original Message- From: Aaron Wolski [mailto:[EMAIL PROTECTED]] Sent: Friday, November 15, 2002 8:45 AM To: 'Jason Vincent'; [EMAIL PROTECTED] Subject: RE: [PHP-DB] Email Encryption? Well.

Just thinking here.. PGP is not an option as it would mean EACH user being setup would need the company's public key to decrypt. Not possible as they setup a few hundred accounts each month.

OFFTOPIC Sorry for the off topic guys.. But I've just been informed that an application we developed for a client whereby they use an Admin tool to setup user accounts into their store needs to have the login (username and password) encrypted. I am thinking PGP for this but to be honest I've never really worked with PGP and wouldn't have the first clue. Does anyone have any experience with this or can offer and advise at all?
