Re: [PHP-DB] Joinging two different mySQL result?
Hehe, I ended up with a mile long sql query since I had to do some smart setup to make all tables work in the UNION. To distinquish between from where the data came from I did this Example (Look at the fromtable) (SELECT id, name, 0 as fromtable FROM table1 where blabla) UNION (SELECT id, company as name, 1 as fromtable FROM blabla) UNION (SELECT id, name, 2 as fromtable FROM blabla) Its not an optimal query thats for sure, but it makes the PHP code 10 times easier and the result is just marvelous.

[PHP-DB] Joinging two different mySQL result?
Im wondering how It would be possible to join two different mySQL results into one set? To clear it up a little bit, say we have two different databases which are completely different but they both share fields name and email. I want to select all the emails and names from both databases and show them in table on the webpage. The first thing that comes to mind is : ALTERNATIVE 1 1. Select the results from table 1 (Which accually is a join select from 2 tables) 2. Select the results from table 2 (Which is a single table) 3. Spin through set one, and spin through set two. This creates a problem since we are talking about eg. 1000 records and I only show 20 a time on the screen with a nice next page in the bottom to browse the results. Another sollution could be : ALTERNATIVE 2 1. Select the results from table 1 (Which accually is a join select from 2 tables) 2. Select the results from table 2 (Which is a single table) 3. Create new array with needed fields, 4. Pump in results 1 5. Pump in results 2 6. Show and browse the array as if it was the accual query. This sounds practical, on the other hand a large set would be wasted bandwidth from the SQL engine and large arrays. Then again, theese queries arnt done often so I shouldnt care to much about the hardware, there shouldnt be more than 10.000 records either at max. (Sure, you never know but statistically there shouldnt). Finally, another sollution, cache the result set : ALTERNATIVE 3 1. Check to see if we have a fresh cache? We dont so we go to point two 2. Select the results from table 1 (Which accually is a join select from 2 tables) 3. Select the results from table 2 (Which is a single table) 4. Create new cache table, punp in results set 1 and 2 5. Do the queries from cache table Anyone have some points on this? I would maby think alternative 3 would be best, or maby alternative 2? Maby you have some other alternatives? -- Kim Steinhaug - There are 10 types of people when it comes to binary numbers: those who understand them, and those who don't. - www.steinhaug.com - www.easywebshop.no - www.easycms.no www.webkitpro.com - -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Here are some tables to reflect the accual problem : So if you can select the two records in one query I would be very happy, :D What I want is this : users.id = users_info.cid I would like to select from users, usr (which is the email ) as email, aktiv, newsletter, emailblock, htmlmode, none_registered and * from users_info where users.id = users_info.cid At the same time from unregistered_users I would like epost, newsletter, htmlmode, newsletter, emailblock Theese two should be merged together, if at all possible.

[PHP-DB] Re: problem....
Well, your query looked confusing to me, but break it up like this
First :
select
Then, name your coloumns, seperate with commas, or use wildcard for all
*
Define from what table you need to select
FROM database_table
Add some select statements with WHERE
WHERE
and the statements itself
1=1
What did I just write now? Looking at your example I guess :
1. you need the coloumns : Rune, username
2. your table : RuneRunner
3. your select criteria : UserID=3
I would then write your SQL query as this :
$sql = SELECT Rune, username FROM RuneRunner WHERE UserID=3;
Then you could do your code,
$pic = mysql_query($sql,$connection);
$pic = mysql_fetch_array($pic);
You would also want to add a database abstraction layer, as for debugging
purposes this will make your life much easier.
Your original code looks to correct if you rewrite it abit, like this :
SELECT RuneRunner_1.Rune, RuneRunner_1.username FROM RuneRunner RuneRunner_1
WHERE (RuneRunner_1.User_ID=3);
Not tested but it should work fine. On the other hand, the referencename
after the
table name should be a short one to make the statement much easier to read,
somthing like :
SELECT rr.Rune, rr.username FROM RuneRunner rr WHERE (rr.User_ID=3);
Then again, since you only have one table in your statement there is no need
for the reference name,
and since your WHERE clause is a single statement there is no need for the
paranthese either.
So you are still back to :
SELECT Rune, username FROM RuneRunner WHERE User_ID=3;

A simple way to debug your scripts would be like this :
FROM :

WorkerID, ClientID, TimesheetDate, ProspectiveOrRetrospective) VALUES
('$TimeSheetID','$WorkerID','$ClientID','$TimesheetDate','$ProspectiveOrRetr

TO
$sql = (INSERT INTO tblTimesheet (TimesheetID,

ospective');
echo 'Query : ' . $sql . \nbr;
$result_timesheet=mysql_query($sql)or die(Insert Error: .mysql_error());
It would atleast give you a good feeling on the data getting passed to mySQL
if youre not getting any error message.

use the EXPLAIN infront of your select query to see what indexes are in use. If you have a double index it wont hurt you, except that you are wasting twice as much space in your DB.

Re: [PHP-DB] Re: HTTP header information
Another little nift thing ive learned to always do regarding headers, is to always - ALWAYS - after a location have an exit; Example : header(location: somewhere.php); exit; Ive learned that sometimes someting odd happens to the server and PHP delivers notices and errors to the browser. Sometimes something in your code could go wrong leading to a header not working the way intended. Point is, having the exit atleast stops the user from getting alot of stuff which he didnt accually want on the screen. I remember one of my earlier login systems, and if the login wasnt valid the user was sendt to the login page, pretty old fashioned. Problem was I didnt have an exit behind, and the webserver got a hickup. There happened someting wrong with the /tmp folder on the server so PHP issued an error on all pages that there was errors with the sessions, meaning something was printed out before my validation of the login, and the user accually got the content he wasnt allowed to see, :) This is abit off topic, but you never know.

[PHP-DB] Re: Count unique visits in PHP/MySQL
Whatabout creating a table containing online users,
where you log every activity with IP, BrowserSession and Timestamp.
You also create a table to track the accual unique visits.
So my logic to solve it :
Update the online table like this (Some rough coding below, not tested at
all, read the logic).
30 minutes = 60sec*30 = 1800
1delete from online where timestamp . (time() - 1800); // Delete
inactive users / uniqe ghosts or whatever
2Update online set timestamp = ' . time() . ' where ip=' . $ip . '
and browsersession = ' . $browsersession . ';
3If (!mysql_affected_rows()){
// Update the Unique visitor table
// Insert new entry with IP, Browsersession and time() into the
online database
}
As far as my midnight brain would see it this would work nicely.

I am making a PHP/MySQL traffic report page from a table that records some
user activity using PHP referrer information.
I have a table with three rows: IP, page_name, and timestamp. The IP row
records the user's IP address, page_name records the name of the page that
the user loaded, and the timestamp row records in Unix timestamp format the
time of day that the user requested the page.
I want to be able to count unique visits per IP according to Internet
Advertising Bureau standards, which count a Unique Visit as a log in by
the same IP once every thirty minutes.
IAB verbatim definition: Visit - One or more text and/or graphics
downloads from a site qualifying as at least one page, without 30
consecutive minutes of inactivity, which can be reasonably attributed to a
single browser for a single session. A browser must pull text or graphics
content to be considered a visit.
So I need to make a MySQL query that will count how many times an IP
logged a timestamp within a given time period.
For example, the publisher checking traffic could request a date between
May 1 and May 31, and I'd like to be able to return a page that counted
unique users (count distinct IP), pages viewed (list distinct pages) and how
many times they visited in that period. I have the first two down, but not
the unique visits. Any ideas?

[PHP-DB] Re: merging a table from multiple servers
Well,
I would do the following, lets assume some servers here :
Server1 - Your server
Server2 - Someone you want data from
Server3 - Another one you want data from
I would create a script which must be installed on every server you need
data from, call it generate.php for example. This script would pull out
all the data your would want to use on your site, format the the data
however youd like it, as a CSV file, MySQL queries or whatever.
Each generate script will write back to the file : batch.txt for example.
(Or it could spit out the results as you trigger the scrupt, but incase
there
are many servers you would encounter the 30second limit on PHP scripts).
For the case of argument we say that the generate.php script spits out
the results the way you want them.
What your server would need to do then would be the following :
You could use fopen to trigger each generate.php file like this from your
site :
---
function fetchpage($page){
$fd=fopen($page,r);
while ($line=fgets($fd,1000)) { $text.=$line; } fclose ($fd);
return $text;
}
$data2 = fetchpage('http://server2/generate.php');
$data3 = fetchpage('http://server3/generate.php');
---
You now have all you need in $data and $data2, you would then
pull your own stats into $data1 and do whatever you like with this.
You could pump all the results into a new table for statistics, or
do it at once and present the result as a HTML.
You should also create a trigger or something for this script so that
it doesnt run on every pageload, maby once an hour or something.
I hope you got the the hang of it.

I would imagine the best way would be a system that triggers a
script on the different serveres. This script creates a datafile
which you import with fopen and then you create the database
set you need to generate nice stats from.
Else you would need the different servers to accept incoming
connections on their MySQL from your host, which I would think
would be alot of work to accomplish. Preparing datasets on the
different servers with a script sounds much more simple in my
opinion, after all this script will only be updated at given
intervals.

[PHP-DB] Re: Optimize Tables
Another question... Why is it that you feel you need to optimize this? There really isnt any need as far as I can see. The overhead is really small, and will probably go up and down by itself since you have people adding and deleting from the table all the time. If we were talking many MB I could understand you, but a few hundred KB is really silly spending so much time avoiding since it will appear in 5 minutes again when people delete something from your table. Another way to completely remove the overhead is to not let people delete from the table, instead you flag the data as deleted. Gives you larger tables, but no overhead. I guess you have made indexes for your database if you have a lot of select in it, thats far more important than optimizing at the moment. -- -- Kim Steinhaug -- There are 10 types of people when it comes to binary numbers: those who understand them, and those who don't. -- www.steinhaug.com - www.easywebshop.no - www.webkitpro.com -- Ng Hwee Hwee [EMAIL PROTECTED] wrote in message news:[EMAIL PROTECTED] Hi, Is there a way to create a schedule to optimise my MySQL tables automatically?

[PHP-DB] Re: Tree structure - how to show only current branch ??
Well, I did a similar system for my CMS sollution. If I understand you correct you want to sort the main branch, keeping the subs. The sorting was in my case the part that I spent most of the time coding. The other part, selecting the subs I did really simple. As a main rule, I only select the main branch and order them, as a sub query I check if there are pages assigned to this branch. If so - present an icon to open the branch with a link link ?branch=999 Lets loop over this again with some more logic, if the $_GET[branch] corresponds with the branch currently in the result set im looping through ill print out the results, we also include a branch close icon with reverse effect, why this is explained below. Else, I skip this and continue with the next branch. Whats bad with this? Only 1 branch can be opened at a time, so what you do is assign the branch variable to the session. Push the variable into an array, and if the branch from the current result set is in the array open it. This way we can keep track of unlimited branches, opened and closed. Together with the close function they get wiped from the array and therefore closes.

Well, Could be some sort of debugging mode on the PHP running on the server. On the other hand your script is depending on the fact that GLOBALS are turned on, which - you shouldnt. 1) Anywho - you form is using POST, so you should use this syntax : $_POST[variable], if using GET the equivilant is : $_GET[variable] 2) You should try to avoid putting variables inside quotes, unless you have a good reason for is. Meaning Hello $variable; should be written as : Hello . $variable; So the answer to your question would be, on the second page, and I also prefer echo instead of print. echo Hello . $_POST[name] . !; or echo 'Hello ' . $_POST[name] .

You do however need to install the ImageMagick module on the server (windows is easy, hust depack the files and point to migrify.exe, no need to install it its just a bunch of DLLs).

[PHP-DB] Re: Validating a Session value
First you need to alter you else if statements, you write :

I would write :
if(($session_ValueA =100) and ($session_ValueA =499)){
$session_fee=20;
}
And as you see, you cant evaluate $20 since PHP doesnt know
that $20 is 20 dollars. It assumes its a variable with name of 20.
The $ (dollarsign), in your case, is just for show. Same goes for the
fee. You will need to work with the numbers only, knowing their
currency, then when you print it out you can typically :
echo '$' . $session_fee;

You could use PHPs internal functions for this, but Ill recommend you using PHPmailer which is heavily documentet with tons of examples on how to use. The PHPmailer is located at sourceforge and you should find it right away. It has to be the most elegant way I know of sending emails from PHP scripts. And as a bonus, the PHPmailer is under active development so you will most likely never run into problems using it, :) -- Kim Steinhaug --- There are 10 types of people when it comes to binary numbers: those who understand them, and those who don't. --- Redhat [EMAIL PROTECTED] wrote in message news:[EMAIL PROTECTED] I have created a simple form that dumps input information into a mysql database.

[PHP-DB] Quering the mySQL DB for statistics results - best way of doing this
Hello,
Im about to write a script that will generate several reports from
a database which loggs all visits. I see that my script will need
alot of queries against the database whenever a report is generated,
and I would love to get some input from you if my way of solving
this is bad.
Example, I have a database filled with informations stored from
each visit, I will only focus on the IP data just here. What I want to
do is, pull out the visits ald present theese on the screen. This is 1
query, and the result gives me a mile long page. To make it a little
better I want to group all the IP, this will give me a much shorter list.
From what Ive understood the group by statement will solve this,
but then I wont know the exact number of each IP. I therefore
need to do an extra database query for each and every IP, right?
Look at this code :
function query(){ // DB Abstraction layer }
$allrecords = query(select * from stats group by ip);
for ($i = 0; $i mysql_num_rows($allrecords) ; $i++) {
$record=mysql_fetch_object($allrecords);
$temp = mysql_fetch_object(query(select count(*) as count from stats where
ip='.$record-ip.'));
$ipcount = $temp-count;
echo 'Echo out needed $record data, this ip has ' . $ipcount . '
entries.br';
}
echo $i . Records totalbr;
This code will generate a heck of a lot of queries againt the mySQL
database, but is it possible to do this another way? This is just one
problem, other reports may dig further into the database and require
more queries if using the above method.
By the way, if you know of any recourses for report making and such I
would love to see them, :)

[PHP-DB] Re: Quering the mySQL DB for statistics results - best way of doing
Thanks for your ideas, im sitting here drinking beer and drinks, so
Im having a little difficulty grasping the whole idea with this new
SQl statement, but it works! Thanks a lot.
To help the other people reading this who might not get it I did
some benchmarking, my method (mentioned in the beginning in
the thread) :
Time - 0.3663
I altered the routine, from 114 nested queries (my dataset) into
1 single query from Justin Patrin like this :
$sql = select ip, count(*) as ipcount FROM stats Group By ip;
$allrecords = query($sql);
for ($i = 0; $i mysql_num_rows($allrecords) ; $i++) {
$record=mysql_fetch_object($allrecords);
echo $record-ipcount . '-';
}
Time - 0.0101
Remarkable difference indeed! Im just happy that I just made 1 single
report script at the moment using my rather terrible queries... :)
Thanks for the help Justin!

Note that this will not work on Oracle and some other DBs. It will work
in MySQL. Oracle will only let you do:
SELECT COUNT(*) count, ip, FROM stats GROUP BY ip

[PHP-DB] Re: Mail problem
Well, i've developed such a system, MarketMAX.
And ill just give you a little tip here :
1. Dont use BCC field, it look bad and your not able to populate
the emails from your database, eg. Dear %username%
Ofcourse if your bulksend the same message, always, then
BCC could spare your from headache.
2. THE TIMEOUTS!
Be aware, very aware, not only do you need to account for
php timeout, you also should be very aware of standard sendmail
configuration regarding spam. Most installations ive encountered
does not like say. 500 emails dumped at them during a few seconds.
They will probably detect you as spam, and all the mails are deleted.
The best part, all cases Ive encountered, you dont get an error so you
think everyuthing is swell - It isnt!
What you need to do is a) create a cron job that bulk sends. eg. 50
emails each 10 second or such. My sollutions was to create a batch
system that pulls the 50 last entries from the batch list, prints out
the
html page with a 5sec meta refresh. This keeps looping till there is no
emails left.
You might be lucky to be on a system that doesnt care how many emails
sendmail spews out, but this is in fact bad. If this is happening, you
probably
will experience someone taking advantage of the system resulting in the
server IP getting blacklisted - and this is very bad for all users.
But if you do it right, and also create a lot of what if scenarios, you
should
be just fine.
Happy programming!

It might be a good idea to set a cron job to send say, 100 at a time over
the space of a few hours, to avoild killing the mail server or the server
blocking connections from you.
Also - use the BCC field to send the mail, this means only one connection
will need to be made to the mail server per batch of addresses, as opposed
to a connection per address (saves bandwidth and mail server!). The mail
server will then send the messages where they need to go and hide all the
other recipents.

Beware though...if there are too many addresses in the db, you may
encounter
timeouts, or your browser may crash (very likely). Increase the timeout
before you do such a mass-mail job.
Also, my comment: If you do not want your receivers to find out who else
you
sent the mail to, don't use the CC method. Just:
for(until max. users reached){
send out new mail to current user
}
Yours sincerely,

maybe use a for loop and mail command.
should work
Or put all the addresses in a CC/BCC field maybe sending every 100
emails
to
prevent a mail overload/blockage due to to many recipients etc.
Hint: look here: http://www.php.net/manual/en/language.variables.php
and
you
can find a way to append more to an existing variable. Very useful in

Not exactly your answer, but I remember having same problems one time.

Just alter 1 line and everything is online again. mail() function may be more than good enough, but you might want to check out the phpmailer which is quite awesome! -- Kim Steinhaug --- There are 10 types of people when it comes to binary numbers: those who understand them, and those who don't. --- Jerry [EMAIL PROTECTED] wrote in message news:[EMAIL PROTECTED] Hi, I have a MAJOR problem with PHP mail() function, one that is odd and very frustrating as I have no idea what is causing it. I have used the one script to send emails out in the past and they have been sucessfully sent out, but as of a few days ago and now they are bouncing, some are actually being sent and some just simply won't go out. So let me explain. I have an admin area of my site where I have all users in a mysql database. Their email address, names, address, etc. The admin side allows me to do many tasks like send out text-based emails via PHP mail() function and HTML emails. What it does is I type in the field boxes and saves to a mysql table, than I run a cronjob to grab the email data and email addresses and send out using PHP mail(). The script worked fine in the past, no problems but now I get the following message when I attempt to send emails: --- This message was created automatically by mail delivery software. A message that you sent could not be delivered to one or more of its recipients. This is a permanent error. The following address(es) failed: [EMAIL PROTECTED] unrouteable mail domain cashgrace.com --- But that's not all, it comes up as that for all domains, like yahoo.com, hotmail.com, bigpond.com etc... All of them, even though they are reachable via webmail. I can go into webmail via CPANEL and send emails and they actually go to the person, so does not seem like a mail server problem or does it? I beleive, but could be wrong, it is somewhere in the mail() function on the root part of the server. But of course I don't have access to it. But the weird thing is this... Some emails 1/10 do actually get sent and delivered, do not bounce, but the other 9 fail. Why? Well I did some more investigating... Well for what I have access to. The Server Load for the Server was flashing RED in the Server Status area. So I persume this is bad? Maybe due to this maybe it's attempting to send emails but looping and not got enough resources to actually do the job and in the end gives up and produces the bounced email? As I said before I could be way off track but worth suggesting and trying to figure it out. Is there a way to DEBUG my mail() function I call in the cronjob? The joy of the CRONJOB is that it's written in PHP also, so I can view it on a webpage. So if there is a way to DEBUG it I should see where the error is? Or won't I? Any suggestions? I've looked long and hard, emailed my admin and they are optimistic with the problem also so thought I'd post here and see what can be done and if we can get some outside help. As I said before the script for the mail() has NEVER been changed. So it can't be my code as it has worked in the past. Must be server side somewhere... Unless my admin has done an update and something has gone wrong. But I thought someone on here would know what could cause the error, at least we can investigate it instead of having no idea what is causing the problem. All the help is needed here if people can provide it. Thanks in advance, and sorry for the long email. But this problem is really giving me the 'you know what' now.

[PHP-DB] Optimal mySQL query for next prev page system
Ive been using the same way of creating queries for the mySQL
database the last years now, but as my databases keep growing
Its time to start thinking of performance.
My question however, is more if the way im doing this is the best way,
or if I should reprogram all my queries in a more optimal way.
The thing Im wondering about is the way I create my
prev page 1 2 3 4 next page scripts. I will show the way I do it,
and if you know a way that is more optimal or better, or you see any
really dumb stuff here talking prosessing power please let me know.
(And im using some abstraction layers for the accual queries, but they
should not need to be optimized any further)
1. I build the query, and assign it to $sql
$sql = select * from mydatabase;
2. I perform the query against the mySQL database
$result = query($sql);
3. I check to see if I have any results at all, to verify if I will show
content at all
$num=mysql_num_rows($result);
if(!$num){ // tough luck buster page! }
else { // continue with the prev/next page routine }
4. Then I feed my prev/next routine with things as page, limit and such.
$pn_putput=showNavigation($sql,$limit,$page);
The showNavigation then, based on the page, limit and mysql_num_rows()
then
calculates out the correct mySQL limit statement to add to the existing
SQL statement,
for example we have :
page=2, limit=10, mysql_num_rows=50, after computed the $sql is like
this :
$sql = select * from mydatabase limit 20,10;
Then I query the mySQL database again to get the final result set, which
I return together
with the buildt prev/next htmlkode
5. I for($i=0... loop thought the result set...
for($i=0;$imysql_num_rows($result);$i++){
$unit=mysql_fetch_object($result);
// blablabla }
6. If there were any output from the navigation routine, I enter this at the
bottom.
That would be my process of doing this. I do have some questions, and
remember that im
referring to working with large mySQL tables 10.000 records.
a) In point 2 I query out the whole database, and with a wildcard. I would
guess if I
compact this abit, say like select id from..., pulling only 1 field
from the result set.
This would spare alot of processing power for both mySQL and PHP?
b) Maby I could just do a mySQL query that would result the total amount of
entries,
just the accuall number - since all I need is the max number to compute
the final sql.
c) Point 5, I preferr using objects compared with arrays, atleast for
database work. I
find it much more portable, since altering the datbabase structure means
I dont have to
enter all my code aswell $unit-name; will always work even if I
insert a new field
infront of it, $unit[3]; however will fail dramatically since the
array has become larger.
Is it just the same what U use, Object or Array, or are there particular
reasons to
use them for surtain work other than what you preferr yourself?
Why repair things that already work is the thing I say all day long, but I
do think however its
time to start optimizing my work before my machinery are all buildt upon old
rusty cogs, :)

[PHP-DB] Re: Applications using multiple databases
Hello! In my opinion what your conclusion is sounds correct. I would not have a system that creates a new database for each and every client. Why? If the sollution is hosted on a random ISP, most of theese does not allow the creation of new databases. However, surtain ISP have packages where you can have multiple databases, but often not more than 5 in total. This would in most circumstances result in you only having 5 customers in each installation. If you are running the system on your own server, there are no problems with this, as you controll the system and can create as many databases as you would want. On the other hand you could solve this by instead of creating unique databases for each client, prefix the tables inside the database with the clients username. This would result in alot of tables, but again would give you access to every server in the world that has mySQL database available - And it would be easy to backup since you only have just 1 database to backup. It is however, in my opinion, smart to have seperate tables and such for each end every customer. Should there be a corruption somewhere, atleast it wont effect all the clients, but only 1 client. (Aslong as its not the main software that destroys/deletes everything in a faulty SQL statement. My applications are done a little different, as I have solved this by installing a seperate installation for each customer. To protect my code I have purchased IonCube Encoder, which encrypts the code and renders it useless for reverse engineering. :) You might want to do the same.

Re: [PHP-DB] using code for multiple sites
Well, on the webservers I am using this would mean that the current user has read access to this folder aswell. E.g. /home/users/james /home/users/matt /home/users/patrick /home/users/shared Im used to that *james* only have read access in .../james/* Matt has only in .../matt/* and such, which would make it impossible to include anything in the .../shared/* folder. Unless you have root privilegies and can set up special rights. This would also only work as all the files are on the same server, as PHP cant include PHP code via HTTP (atleast in my knowledge). I have another sollution, which isnt quite as good, but I program all my PHP in classess and have a standard class file, that is identical for all customers. Difference is only what classes each client are using. As I develop my classess I see to that they are always backwards compatibel, this way I only have 1 (or more, but same directory) that I have to update.
