First, do a query to find out how many rows. select count(*) from table where (your where clauses for the query); That's your # of records.

IMO It is bad to store lots of data in session variables.
The $_REQUEST var for the post/get should be enough.
URL: search.php?page=10
code:
$conf['maxresultsperpage'] = 10;
$ref = mysql_query("select count(*) as c from table where subject like '%foo%'");
list($cnt) = mysql_fetch_array($ref); // will assoc work here? dunno, didn't test
echo "Displaying ".($conf['maxresultsperpage']*$_REQUEST['page'])-9." through
".($conf['maxresultsperpage']*$_REQUEST['page']).".";
$ref = mysql_query("select subject, data from table where subject like '%foo%'
limit ".$conf['maxresultsperpage'].",
".($conf['maxresultsperpage']*$_REQUEST['page'])-10);
// loop through array returned from mysql
echo "Next";
I think. It might need some tweaking, but you get the idea (I hope).
No need to store variables here.

If you are running it out of a DB, limiting the results to result 1-10 or 91-100 is pretty fast; caching results seems like more of a headache to me, and depending on how loaded your DB is, not worth the effort. If the query takes 3-5 seconds, then either your DB is configured wrong (no indexes), or your SQL is not written well, or you should consider some sort of DB query caching. Look to the manual for that. ------- Peter Beckman Internet Guy [EMAIL PROTECTED] http://www.purplecow.com/ --- -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP-DB] MySQL - separating web and database servers
Change, in the /etc/hosts file, this:

Hopefully this will work. Haven't tested, just a suggestion. Probably
breaks a few other things, but at least mysql will work.

[PHP-DB] Oracle Client Libraries for Linux
Folks -- I've been trying to figure out where the Oracle client libraries live, but I'm confused as hell.

Great -- but which options presented horribly by Oracle do I download?

[PHP-DB] Function that outputs "at line xxx"

[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?

Re: [PHP-DB] Function that outputs "at line xxx"
John, that does work! Thanks. The problem is this: Database calls are in db.inc. The script problem occurs in wine.inc. True, the SQL is called and executed from db.inc, so __LINE__ and __FILE__ are correct in a way. But how do I find out where in the execution of my script the other files are in their execution? index.php --> calls function in wine.inc --> calls function in db.inc --> throws SQL error, calls function in wine.inc --> which prints error to user nicely and exits What I want is when db.inc throws the error and passes the error text to the db_error function in wine.inc to look pretty for the user, I want to know where the function db_query was called in wine.inc (one level up, the script which called the function now running).

Re: [PHP-DB] TOO MANY CONNECTIONS!!
You can also do something like this:
if ($db_link = mysql_pconnect($host, $user, $pass)) {
if (mysql_select_db($db,$db_link)) { return $db_link; }
else die("MySQL Error: Cannot select {$db} database using {$user}@{$host}:
".mysql_error());
} else die("MySQL Error: Cannot connect to {$db}: ".mysql_error());
make $db_link global (if you use this in a function) then you can know that
you are connected if your script is still running.
If you make two connections, just make db_link something different for the
other connection, and do this:
$x = mysql_query("Select * from users",$db_link);
That will force PHP to use the $db_link specified instead of the "last
opened" connection.

This sets $x = 1 before the loop. The first time it goes through the loop
it does something for the first record and sets $x = 0; Every time you

Re: [PHP-DB] localhost versus remote
That's some nasty code
Two things:
1. What is $ton in your query?
2. Change your mysql_query row to this:
$result = mysql_query($query) or die("MySQL Error: ".mysql_error()."SQL:
$query");
So when your query dies, you'll know why.

Re: [PHP-DB] localhost versus remote
It seems to me you have no idea what you are doing. You really need to
learn how to troubleshoot your code, as this is a very simple problem to
fix. It's not your code. The variables you put in your SQL are empty.
Your code:
$query = "SELECT * FROM $table WHERE Field1 LIKE '%$icao%' $ton
Field2 LIKE '%$name%' $ton
Field3 LIKE '%$country%'
ORDER BY $sort";
Problem:
$ton should equal "AND" or "OR" but it doesn't equal anything. In fact,
all of your variables are either empty or not set.
You are trying to get:
Select * from table where field1 like '%something%' AND
field2 like '%something%' AND
field3 like '%something%'
order by field1
But since $ton is empty you are executing this:
select * from airline_a where field1 like '%%'
field2 like '%%'
field3 like '%%'
order by
Which is COMPLETELY INVALID. Notice no "AND" statements between fields?
I won't publicly flog you, but please don't respond. I believe this list
is for help with more advanced issues, not "how to properly write an SQL
command and troubleshoot your code for you."

Re: [PHP-DB] localhost versus remote
Please stop responding to the list. Your problems are far to simple to
bother everyone on the list.
I have no idea what you mean when you say "locally" or "remote."
Basically your problem is that your script does not see any of the
variables. They are empty or not set. They are not getting passed from
the form. Who knows. php.ini configured differently locally than
remotely.
I assume that Server1 is local and server2 is remote. The problem is that
server2 probably hasn't got "register_globals" turned on.
Do this:
Change all your variables that you don't define in your script to this:
$GLOBALS[icao]
$GLOBALS[name]
$GLOBALS[country]
$GLOBALS[sort]
etc. Also, to see if they even exist, use this:
echo "";
print_r($_GET); // or use print_r($_POST) if you are using a POST instead of a GET
method for your form
echo "";
This prints out all the variables stored.
I would also see if the variables are empty (which they are from what you
show). Put this line in your script:
if (empty($ton)) die("variable ton is empty ($ton). Global: ({$GLOBALS[ton]}) POST
({$_POST[ton]}) GET ({$_GET[ton]})");
If it dies there, it will print out the Global, Post and Get variables of
"ton" to see if they exist there. If they do, then you know you have to
change the variables in your script to those variables in order to get this
to work.
Do you know what version of PHP you are using locally and remotely? If
remotely is not above 4.0.0, then there is different values for _POST and
_GET.

Re: [PHP-DB] localhost versus remote
First off, use quotes. If you are going to be a good coder, always use
quotes in your HTML and your PHP.
In PHP:
$table="aviation_a"; // NOT $table=aviation_a;
Sure, they both work, but they can cause problems in the future, and it is
considered BAD CODING. USE QUOTES. Fix all your input tags with quotes.
The problem is that PHP on the remote end probably doesn't have
register_globals set. Change your code according the email I just sent.

RE: [PHP-DB] PHP/MySQL and passing url params
Why'd you use it in the first place? Where does $row_rsID['userID'] get
set? Why is it in your script if you don't know where it is set and what
it is set to?
You set it like this:
$row_rsID['userID'] = "whatever you want here, probably an int like '0'";
Several ways to define arrays:
$array = array(); // set empty array
$hash = array("stuff"=>"foo"); // a hash effectively
$array = array();
array_push($array, "stuff to push onto the array");
$array[] = "foo"; // same as "array_push"
$array[37] = "foo"; // set array index 37 to foo.
$array['stuff'] = "foo"; // set "hash" (array using words) stuff to foo
$array[0][0][stuff] = "foo"; //multidimensional array.
$array[0][1][stuff] = array("stuff"=>"foo");

Re: [PHP-DB] data_seek and fetch_row
One problem: you are using a database wrapper for which you have provided
no information. $db->query is a function of a class $db, but we don't know
what that function does exactly.
Anyway, the $queryid doesn't contain a valid MySQL result resource. So go
back a few steps. Is $various_query a valid MySQL result? Print it. Keep
adding print statements all over the place until you find out when
$various_query is no longer (or if ever) a valid MySQL result resource.
My bet is that $db->query isn't returning a valid MySQL result. Do a print
after your query on $various_query and see what it shows. It should show:
Resource id #2
or something similar when you print it.

Re: [PHP-DB] Interbase BLOB problem
Your SQL query doesn't need that semicolon at the end of the query -- lose
it.
I never used ibase, so here's what I found from the PHP Manual page for
ibase_query:
Using BLOB
Insert BLOB:
/* create blob */
$blob_id = ibase_blob_create();
/* fill blob */
ibase_blob_add($blob_id, $var_datablob);
/* close new blob */
$blob_id_str = ibase_blob_close($blob_id);
/* insert into table */
ibase_query("INSERT INTO BLOB_TABLE (ID, BLOB) VALUES (1, ?)",$blob_id_str);
Open BLOB:
/* query */
$set = ibase_query("SELECT BLOB FROM BLOB_TABLE WHERE ID = 1");
/* fetche a row */
$row = ibase_fetch_object($set);
/* open BLOB for read */
$blob_id = ibase_blob_open($row->BLOB);
/* get BLOB data */
$stringBLOB = ibase_blob_get($blob_id);
/* print BLOB */
echo $stringBLOB;
/* close new blob */

RE: [PHP-DB] Column Defualts
With MySQL you save a bit by declaring a column not null. If it is null, you are using a bit. For performance on high volume and high transaction servers, declaring your columns not null will help, if only slightly.

RE: [PHP-DB] Column Defualts
This should be useful, mysql-wise: http://www.mysql.com/documentation/mysql/bychapter/manual_MySQL_Optimisation.html#Data_size Declare columns to be NOT NULL if possible. It makes everything faster and you save one bit per column. Note that if you really need NULL in your application you should definitely use it. Just avoid having it on all columns by default.

Re: [PHP-DB] new to cookies
First off, cookie documentation:
http://www.php.net/manual/en/function.setcookie.php
Second, since you store your info in the DB, it might be easier and more
scalable to use a "$user" object which contains everything about the user:
userID, username, email, etc. for quick reference:
$user = mysql_fetch_object($result);
$user->id is now (ie) 37.
$user->username is now Seabird
$user->password is now superman
Now register the user variable to the session:
session_start(); // will start the session unless it is already started somewhere
else
session_register("user"); // note, no dollar sign!
Now if you have register_globals on, $user will be defined globally. If
not, $GLOBALS[user]->username or $_SESSION[user]->username will work.
Now go add a column to your user table called "login_cookie." Do something
funky like
$cookie_string = md5($user->username.$user->email.date("r"));
$x = mysql_query("update user set login_cookie='{$cookie_string}' where
id=$user->id");
Then
$encID = rot13(base64_encode($user->id)).
$cookie_contents = "$encID|$cookie_string";
setcookie("MYcookie_string", $cookie_contents, 13); // fix that expire date
to whatever you want, 3 days, 6 months
When the user comes to any page of the site:
if (!empty($_COOKIE[MYcookie_string])) {
list($encid, $str) = split("|",$_COOKIE[MYcookie_string]);
$realid = rot13(base64_decode($encid));
$x = mysql_query("select * from users where login_cookie='{$str}' and
id={$realid}");
if (mysql_num_rows($x) == 1) {
$user = mysql_fetch_object($x);
session_register("user");
} else { // delete the cookie, it's bad
setcookie("MYcookie_string","");
}
}
Now if their cookie string and their user ID matches what you have in the
DB, then you log them in via sessions. If not, you do nothing.

Re: [PHP-DB] Session variables and arrays
Well, can't say I see the same problem:
"bye");
print_r($_SESSION['foo']);
echo "\n\n";
print is_array($_SESSION['foo']);
Outputs:
X-Powered-By: PHP/4.2.2
Content-type: text/html
Array
(
[hi] => bye
)
1
Which is what I'd expect it to show.
Now how did you assign categories?
Maybe the var is a scalar and is actually "Array (\n [0] => '1';\n [1] =>
'12';" and you are confused.o
If you are saying:
$_SESSION['categories'] = "Array (
[0] = '1';
";
Then it IS a scalar. Try this:
print ":::{$_SESSION['categories']}:::";
If you get this:
:::Array:::
Then I have no clue what the problem is
If you don't get that, then we know what your problem is.

Re: [PHP-DB] losing my session variables
Put "session_start()" somewhere in your code.
$_SESSION isn't set until you "start" your session.
And don't set session variables by $_SESSION[foo] = bar;
DO this:
$foo = bar;
session_register("foo");
Much better.
However, if anyone can correct me, go for it. I just believe that setting
global variables that the system controls and writes is a bad idea unless
you use the functions that you should.
Get out of the habit of SETTING variables using $_POST or $_SESSION or
$GLOBALS. DO get in the habit of setting globals by just setting your
variables correctly in the right scope.

Re: [PHP-DB] Re: losing my session variables
prepend.php gets called before running any page on a site. Put the
"session_start()" in the prepend.php and you won't have to worry where you
put it.
Learn more about it on the php web site (don't have the url handy).

Try this after that print:
print is_array($_SESSION['categories']);
You should get a 1 -- if you don't, try this:
print gettype($_SESSION['categories']);
You should get "array" but if you don't, there is something strange going
on! If you get "string" though, do this:
print strlen($_SESSION['categories']);
If you get "5", then the variable might be a string with the contents
being the word "Array". Pretty doubtful, but we're being thorough here.

RE: [PHP-DB] Session variables and arrays
After a little more research I found out strlen will return 5 for a real
array too, so throw that out. However, since gettype prints a string not
an array, I just don't know. print_r prints the array, but you can iterate
through it.
Do you do this before your loop?
reset($_SESSION['categories']);
print_r($var) will set the pointer to the end of the array, so you have to
reset it to the beginning before you iterate through it again.
Maybe this is the problem?

Re: [PHP-DB] SESSIONS
Do this instead:
$user = mysql_fetch_object($sql_result);
$_SESSION['user'] = $user;
Then, you can use stuff like:
print "{$_SESSION[user]->name}";
// or if register_globals is on
print "$user->name"; // which is nice because you don't have to {} the var or
".$var[name]."

Re: [PHP-DB] killing cookie
You are doing it wrong then. Are you checking $_SESSION['username'] or
$_COOKIE['user'] to determine if the cookie is being deleted? Or looking
in your cookies.txt (or similar) file/directory to see if they still exist?
What exactly is your PROOF :-) that the cookie is not deleted?

Re: [PHP-DB] Generating readio buttons
Here's your problem:
"acct[]" doesn't equal anything.
$acct[4] might.
So:
echo "";
might give you want you want.
The name='acct[]' is used for PHP form processing, putting the correct
value in the variable. For example, $acct[Yes] might be set if you used
this input and it was checked:

Re: [PHP-DB] sort by date
Hey, there are a lot of new people who are starting with PHP. We all are here to help people learn how to use PHP because we are all PHP fans and want the world to use PHP. register_globals is an issue that us more advanced folk know about and deal with on a regular basis. There are lazy people who don't know how to use a manual. However, we've got the ability here to help people who don't know about or how to use the manual. And honestly, some questions are more difficult than the manual provides, especially if you aren't sure where to look. How's this? Anytime someone posts a potential answer, post the manual page for the function, SQL reference or something related. That way it's in the newsgroup and the archives. People DO search the archives, while some people don't. We can't all expect everyone to be as smart and as knowledgable about PHP as some of the people on this list are. So give them a chance and help them learn how to learn instead of getting mad. And if you get mad, maybe this isn't the right place for you to be! I mean that in the nicest sense; the world is filled with idiots, and this list is here to help both idiots and geniuses get through their stumbling blocks by being an intelligent, helpful and friendly community. At least that's what I hope this is. Peter On 6 Nov 2002, Marco Tabini wrote: > Well, excuse me for being a bit cynical, but it's hard to be > philosophical with a deadline hanging over your head.

This is how you'd find it in the future.

RE: [PHP-DB] Imploding an array?
Well, your code will do this:
if delete[7] == 1, you will print_r($order_index[7]) which contains ???
Now from what you say $order_index[7] == "2627";
That's just weird. Whatever it is you are doing is bad.
Regardless, you could do this:
$foo = preg_split("//",$order_index[7]);
Now $foo is an array of [0]=>2, [1]=>6, [2]=>2, [3]=>7;
Now you do a while loop:
for ($x=0;$x<=count($foo);$x++) {
if (is_odd($x)) { $next = 1; } else { $next = 0; }
$str .= $foo[$x];
if ($next) $str .= ",";
$x++;
}
Or something like that. is_odd may not be a function, but YOU figure out
how to determine if a number is odd.

Re: [PHP-DB] MySQL password protection?
Create a user "nobody" with no password and give that user select, update, delete and insert capabilities in your DB and can only connect from localhost (or a certain host). This way they have to be on localhost in order to gain access to your tables, and only then be able to do what your nobody user can do. Then you need to make sure nobody can gain access to localhost without express permission (i.e. plug all security holes). Why are you showing people your source-code that has your password in it?

Re: [PHP-DB] MySQL password protection?
And make sure you make sure the webserver will not SERVE that file!!! You see the source, see that you are fopening the file, I'll find it on your system and get it from the web server and I have your password! Make sure the file is NOT in the document root that the web server serves from. You could also just use the file ".htpasswd", usually by default web servers will NOT serve any file named that. However, much safer to put it somewhere that the web server cannot see (but your PHP script can). Also, this is just as insecure as the other way to any person with a login on the box your PHP script is in. Usually the script is owned by nobody:nobody or read-write all, in which case all local users can get your password. The nobody method at least keeps no password.

Re: [PHP-DB] Record IDs: Numeric or String??
Always use ints. Also, make sure you actually need an INT before using it: Max Value Unsigned Integer: 4.3 billion or so Unsigned MediumInt: 16.7 million unsigned SmallInt: 65,535 unsigned TinyInt: 255 If you'll only ever have 300,000 rows in a table, use a mediumint. Saves space and sorting time. I use mediumint on almost all tables for primary keys and foreign keys.

Re: [PHP-DB] [Newbie Q] csv file upload via php to mysql tutorialrequest
1. learn how to do a file upload in PHP:
http://www.php.net/manual/en/features.file-upload.php
2. Process the CSV file line by line in a loop. Not posting your CSV file
format, I can only guess that it will be in proper form. If so:
for loop {
$csvline = '"column1","column2","column3"';
$r = mysql_query("insert into table values ($csvline)");
}
This assumes the data in your CSV file is the same as your DB structure.
If not, do this:
$r = mysql_query("insert into table (column1,column2,column3) values ($csvline)");

Re: [PHP-DB] ROugh idea of speed
I was running a site on a dual 800 CPU, 1GB ram, dual mirrored 18GB drives, doing about 16.8GB per day on average, including PHP/HTML code. The system had several tables (~20), some regularly accessed, some not. The biggest table was a log table of about 2.5+ million rows. Ran reports from it without a problem (as long as I wasn't sorting by date!). Was able to run apache + php + mysql doing 1M page views a day, all generated based on info in the DB. Probably ran at about 150+ queries per second all day long. This was on FreeBSD, not Linux. Hopefully this gives you a bit of an idea. As for 500 million records, if they are all in one table, that's something I've never tried to do before!

Re: [PHP-DB] Polls?
Use the dual table questions and answers suggestion before.
Then just use a loop:
$question = mysql_query("select * from questions where id={$this_question}");
while ($r = mysql_fetch_array($question)) {
$answers = mysql_query("select * from answers where qid={$r[id]}");
while ($s = mysql_fetch_array($answers)) {

Re: [PHP-DB] Polls?
Well, you are gonna have to do two queries if you want a dynamic number of
questions in each poll, unless you want to do something limited and have
10 to 20 columns for each poll and leave the questions not questioned
null... IE:
table poll
pollid
name
descr
question1
question2
question3
question4
question...20
Now this assumes that each question has the same set of potential answers,
or this doesn't work.
The two table polls + questions (or even three tables, polls, questions,
answers) wouldn't kill your server:
$x = mysql_query("select * from polls");
$y = mysql_query("select * from questions");
$z = mysql_query("select * from answers");
Then just iterate through them all, put them in an array:
$polls[$row[id]] = $row_from_db;
$questions[$row[id]] = $row_from_db;
$answers[$row[id]] = $row_from_db;
Then just relate them.
while(list($pollid,$row)=each($polls)) {
print $row['name']."".$row['descr']."";
reset($questions);
while(list($qid,$ques)=each($questions)) {
if ($ques[pid] != $pollid) continue;
print "Question. ".$ques['question']."";
reset($answers);
while(list($aid,$ans)=each($answers)) {
if ($ques[pid] != $pollid) continue;
print "{$ans['answer']}";
}
}
}
Now you have done everything you need to display all the polls in PHP and
not in the DB. I have no clue why you'd want to do it this way, but if
your MySQL server is that taxed, then this is how I'd do it -- put the
processing on the web server.

[PHP-DB] Email and HTML Parser Library
Hey Folks: I admit, I haven't searched for this anywhere yet, but I thought I'd ask for opinions first. I'm looking to parse an email. Some emails are HTML, some are not. What I want to do with an email is: 1. Split the headers from the body 2. Remove MIME attachments that aren't txt or html from the body 3. Grab all the HREF urls in the body as well as image SRCes (fully qualified, so if there is a "http://www.purplecow.com/hhs/ img http://purplecow.com/gfx/icons/new.gif Are there any good libraries of functions that would aid me in this effort? The idea is to store the headers in the DB, store the body in another table, and store hrefs and image URLs in another table. The URLs will be used to see if there are redirects to somewhere else and make a "parent" association. Any thoughts, pointers, urls or code would be appreciated!

Re: [PHP-DB] problem with postgres
Well, I don't know specifics of postgresql, but I'll give it a whirl.
http://www.php.net/manual/en/function.pg-last-error.php
This function should give you the error about WHY it was unable to connect.
If not, check stuff like permissions, making sure pgsql.so (or whatever it
is named) is actually compiled in (use phpinfo() to determine, and looks
like you already confirmed that), make sure you are connecting to is
resolving in DNS if not localhost, and the user can connect to the DB set.
$dbconn3 = pg_connect ("host=sheep port=5432 dbname=mary user=lamb password=foo");
Also from the PHP manual site:
A lot of the questions that appear here can be answered by looking at the
PostgreSQL programming documentation (www.postgresql.org). PHP's
PostgreSQL interface appears to be heavily based on the libpq programming
interface.
If you use PostgreSQL users for authenticating into your pg database
rather than using your own authentication, always specify host
directive in pg_connect and edit pg_hba.conf to authenticate from this
host accordingly. Otherwise, PHP will connect as 'local' using UNIX
domain sockets, which is set in pg_hba.conf to 'trust' by default (so
you can connect using psql on console without specifying password) and
everyone can connect to db _without password_ .

Re: [PHP-DB] retrieving data from mysql table
Notice that you are adding $x in the loop. You are getting a row, printing
out index 0 of table_headers, incrementing $x, then moving to the next row.
Basically you are fetching row 1 column 1, row 2 column 2, row 3 column 3,
etc. instead of fetching all rows.
Do this instead:
$query = "SELECT * FROM " .$table. "" ;
$result = mysql_query ( $query ) or die( mysql_error () );
while ( $row = mysql_fetch_assoc ($result)) {
while(list(,$col)=each($row)) {
echo "{$col}";
}
}
This will echo all rows, and for each row will echo all values in order of
your table, which is also the order of $table_headers.

Re: [PHP-DB] Performance for how many columns to update?
Straight from the MySQL Documentation, which is where you should look first
always:
http://www.mysql.com/documentation/mysql/bychapter/manual_MySQL_Optimisation.html#Update_speed
5.2.10 Speed of UPDATE Queries
Update queries are optimised as a SELECT query with the additional
overhead of a write. The speed of the write is dependent on the size of
the data that is being updated and the number of indexes that are
updated. Indexes that are not changed will not be updated.
Also, another way to get fast updates is to delay updates and then do
many updates in a row later. Doing many updates in a row is much
quicker than doing one at a time if you lock the table.
Note that, with dynamic record format, updating a record to a longer
total length may split the record. So if you do this often, it is very
important to OPTIMIZE TABLE sometimes. See section 4.5.1 OPTIMIZE TABLE
Syntax.
If you aren't doing an update of 50K per row, updating 3 columns instead of
1 will be "much quicker" (quoted from the manual). If you are doing 10,000
updates, read more of the manual on the syntax of UPDATE because you can
delay your updates which allows MYSQL to update the table at its leisure
which offers better performance.

Re: [PHP-DB] Performance for how many columns to update?
Update them all. It is easier (and faster) to do that even if none of them
has changed than it is to try and figure out which one changed. MySQL
doesn't do anything if the row/column hasn't changed, so there is only the
overhead of a connection, which is already there since you are doing the
fetch/query.
Being lazy actually has its benefits in this case. Doing the fetch and
then testing if you should update is actually more taxing on the DB (and
the server for that matter if we are talking in CPU cycles) than it would
be to just do an update on all columns with a where clause on an indexed
(or preferably primary keyed) column.

YES! 20,000 records is still a lot of records, and indexing on
commonly/frequently searched, non-primary-key fields (like email address,
last name, or zip code for example) will definitely help speed things up.
ALSO, making sure fulltext indexing is on your text fields if you are
searching your paragraphs of text will significantly help the queries.
When you query your fulltext columns (anything of type TEXT), use this:
select match(column1) against ('myquerytext') as blah,column1,column2,column3 from
table order by blah desc
This will return something like this:
2.393888483| column1 contents | column2 contents | column3 contents
1.938323487| column1 contents | column2 contents | column3 contents
if they match 'myquerytext'. Search mysql.com documentation for fulltext
indexing.
> Also, do you create an index on everything or just 1 item or or or :-)
Depends. If you search on a single column almost always, then make an
index on that one column. If you do "select * from table where col1='x'
and col2='y'" then you'll want to create an index that includes col1 and
col2. Again, read the manual on mysql.com on indexing.

Re: [PHP-DB] php array max value pr. year
First create this array before you do anything:
$max = array(10=>1,
20=>1,
40=>1,
60=>1,
320=>1,
780=>1,
890=>1,
920=>1);
$year[2002] = $max;
$year[2003] = $max;
$i = 0;
while(list($a,$b)=each($v)) {
$year[$y[$i]][$v[$i]] = 0;
}
reset($year);
while(list($a,$b)=each($year)) {
while(list($c,$d)=each($b)) {
if ($d == 1) $next[$a][$c]=1;
}
}
At this point $next will be a two dimensional array IF all the V's in a
year are not used up. If they are, $next[2002] for example will be
!isset($next[2002]).
To get your $Y and $V:
reset($next);
while(list($a,$b)=each($next)) {
$leftoveryears[] = $a;
while(list($c,$d)=each($b)) {
$leftovervalues[] = $c;
}
}
Now $leftoveryears is an array of years and $leftovervalues is an array of
values.
I would highly recommend using a single multi-dimensional array instead of
blind indexing for your year to value pairs. IE:
$pairs[2002][10] = 1; // (if set)

Re: [PHP-DB] payperiods
$nextpayperiod = mktime(0,0,0,$month,$day+14,$year);
$humanreadabledate = date("r",$nextpayperiod);
where $month is numeric month, $day is the last payperiod day (1-31), and
$year is the year of the payperiod.
$nextpayperiod will equal the unix timestamp of 14 days from the last payperiod.

RE: [PHP-DB] payperiods
Put the dates for employees into one table.
In another, put the payperiods.
You could populate the payperiods table for the next 90 years if you wanted
if it is always on a 2 week schedule.
To look at past payperiods:
select start, end from payperiods where start = '$querydate';
Or just date, but you'll have to decide if the date in the payperiod table
will be the start of the payperiod or end of the payperiod. IE:
select date as start,date_add(date,interval 14 day) as end from
payperiods where start = '$querydate';
Then get the employees who put in time between those days, assuming $pp
contains the row found:
select * from timesheets where date>={$pp[start]} and date<{$pp[end]};
Then you'd have all of the hours employees put in. Then just sort by
employee name (add a group by) and/or sum their hours, etc.
Pretty easy.

Re: [PHP-DB] Multiple Inserts with mySQL
Try this: $stack is an array of hashes: $stack[0] = array(0=>tablename, 1=>insertid()); For each insert you do, push an anonymous array on $stack which includes the tablename and insertid of the insert. Then as you continue your inserts, if any of them fail, call a function which takes that array $stack, and iterate through it, deleting the rows you just inserted. (see mysql_insert_id() function to get the insert ID) If none of them do fail, then you are in the clear. Either unset $stack or ignore it.

Re: [PHP-DB] Arrays again again
The problem there is that you've got $a[$year] getting set a bunch of
times. That is busted code. $a[$year] will only contain the LAST value.
Replace that line with this one.
$a[] = array(year=>$year, value=>$value);
OR
$a[$i] = array(year=>$year, value=>$value);
Now $a[0][year] = 2002
Now $a[0][value] = 320
And on and on.

Re: [PHP-DB] Shopping Cart Sessions - Think this is a simple prolem- hopefully
1. Are you 100% sure register_globals is turned on?
2. You session_register your variable before you change it. Replace
$ShoppingCart with $_SESSION[ShoppingCart] every time you use it. This way
you are modifying the session variable actually in the session, not just
the one time.
session_register() copies the named variable into the session space, but
adding or removing items from that variable does NOT change it in the
session if you use _register. If you modify $_SESSION[shoppingcart]
every time, then you are actually reading/writing to the real session
variable and don't have to worry about it.

http://www.php.net/manual/en/function.rename.php
You are just moving files on a file system from one place to another right?
rename("/old/path/to/file/filename.pdf","/new/path/newfilename.pdf") or die("can't
move file");
Can't remember what variable/function holds the last error for rename,
otherwise I'd put it there.

RE: [PHP-DB] Email Encryption?
Why not encrypt the password in the DB? If they lose their password, it cannot be sent to them. They chose it, so it doesn't need to be sent to them in their email. If they lose it, it is changed, and they have to change it again. That way, only if they are stupid do they have an extra step. The passwords in the DB are encrypted, so only if someone gets a hold of the DB can the passwords be cracked by brute force. md5 would work fine for this. It is the same security that FreeBSD uses in their password file.

RE: [PHP-DB] Email Encryption?
At the time of the account setup, you'll have the unencrypted and encrypted password. Send the email before it gets encrypted. Still, this is a little silly, since the email is unencrypted. I guess you could base64 encode the email, but that'd take an extra step. Oooh, what about this? Send an email that takes you to an https: page that only can be viewed by entering a valid code sent in another email? This https page, given the right code, will give you your username and password? The two separate emails provides a bit of obscurity, and the password is always encrypted. On the server side, if these accounts would only be accessed from certain IP blocks, you can block other requests.

Re: [PHP-DB] Query Executes in MySQL Command Line, Not From PHP.
Can you post the "explain levelone" here? One thought is that 1contentID
is a char or varchar instead of an int. Then again, if it were, that exact
code shouldn't have worked.
Are you sure you are doing the query using $sql_element_low and not
something else? You may be echoing it but are you actually using the query
to execute, or did you copy the mysql_query() command from another line and
forget to change the var?
Also, I hate ". and .", makes for messy life. Try this:
$sql_element_low = "UPDATE {$table} set medialow=NULL WHERE
{$_POST['tbl']}contentID={$_POST['id']}";
Also, does medialow have a unique index on it? This could cause it to
fail. Or is medialow defined as NOT NULL?

Re: [PHP-DB] database update question
you could do substring
update table_name set col_name=concat(substring_index(col_name,".pdf",1),".zip") where
col_name like "%.pdf"
What does this do? From the man page:
SUBSTRING_INDEX(str,delim,count)
Returns the substring from string str before count occurrences of the
delimiter delim. If count is positive, everything to the left of the
final delimiter (counting from the left) is returned. If count is
negative, everything to the right of the final delimiter (counting from
the right) is returned:
mysql> SELECT SUBSTRING_INDEX('www.mysql.com', '.', 2);
-> 'www.mysql'
mysql> SELECT SUBSTRING_INDEX('www.mysql.com', '.', -2);
-> 'mysql.com'
This function is multi-byte safe.
What does it do here?
mysql> select concat(substring_index("filename.pdf",".pdf",1),".zip");
+-+
| concat(substring_index("filename.pdf",".pdf",1),".zip") |
+-+
| filename.zip|
+-+
The ONLY problem you will have with this is if the filename is something like this:
filename.pdffile.pdf
This code will rename it filename.zip, not filename.pdffile.zip as expected.

[PHP-DB] Passing by reference
I'm building some software that will be passing a string variable which
could potentially be up to 125K bytes (characters) in size.
I know that passing a reference to the variable will be much more efficient
than copying the variable:
copying, as I understand it:
foo($var)
[...later...]
function foo ($myvar) { $sql = "insert into table (this) values (\"$myvar\")"; }
passing by reference, not copying:
foo($var)
[...later...]
function foo (&$myvar) { $sql = "insert into table (this) values (\"$myvar\")"; }
A few questions:
1. Am I correct that PHP makes a copy of the variable when I call the
function with the variable, since the scope will not 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!
Thanks,
Peter

Re: [PHP-DB] Need Help
A few suggestions.
$show["Time"] doesn't exist; replace the 5 lines after your "while" with
this:
$sms_time=$show["sms_time"];
$smsc=$show["smsc"];
$org_sms=$show["org_sms"];
$dest_sms=$show["dest_sms"];
$msg_content=$show["msg_content"];
Also, so save you some formatting headaches, change your $s_sms to this:
$s_sms="SELECT from_unixtime(unix_timestamp(sms_time)) as
sms_time,smsc,org_sms,dest_sms,msg_content FROM dlr WHERE smsc=('Receive SMS')";
This will format your sms_time from the DB as year-month-day hour:minute:second
select from_unixtime(unix_timestamp(now()));
+--+
| from_unixtime(unix_timestamp(now())) |

[PHP-DB] Inserting things into the DB
Having a little trouble doing some inserts into a db.
The problem is escaping the right characters. Data integrity is important.
Right now, I have taken an email and split it into $body and $header
(containing the respective parts of the email) using my own parsing loop.
Fairly simple, it doesn't really need to be posted.
Before running dcc on it (see http://www.rhyolite.com/anti-spam/dcc/ if you
want to know more), I escape the quotes:
$all2 = preg_replace("/\"/","\\\"",$header."\n".$body);
$cmd = 'echo "'.$all2.'" | dccproc -C';
$output = `$cmd`;
That works great. Does what I want it to do, at least I think it does.
The larger problem comes later -- the insert:
$body = preg_replace("/\/","",$body);
$body = preg_replace("/\"/","\\\"",$body);
$x = db_query("insert into body (submitter,md5,fuz1,fuz2,body) values
(1,'{$dcc['Body']['md5']}','{$dcc['Fuz1']['md5']}','{$dcc['Fuz2']['md5']}',\"{$body}\")");
Now this works great for a good amount of emails. I was just escaping the
double quotes, but then I found a case where an email had in the actual
email a backslash before the quote, so I added the first regex as well.
But then I start running into problems:
Syntax error: EOF in backquote substitution
or
Warning: No ending delimiter '/' found in
/home/beckman/public_html/work/spamtracker/stlib.inc on line 45
line 45: $body = preg_replace("/\/","",$body);
I truly suck at regexs, and for the life of me I haven't been able to teach
them to myself. If anyone can't point me in the right direction, I think
this is easily solved with a better regex than what I have.
Why not just use addslashes()? addslashes will escape the single quote,
and it will persist through the insert, which cannot happen (need to be
able to prove the md5 hashes generated by DCC is accurate, and adding
slashes in the wrong place will screw that up).
What's the answer? addslashes then remove the single-quoted-slashes?
Thanks for the help.

Re: [PHP-DB] Sorting in numerical order, and then randomly
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.

Whoops, the $GLOBALS[acdb] was legacy code for the site I was using.
Ignore it. Sorry! Your SessionTableName is set in php.ini -- if
$sessiontablename is empty, there is an issue that will prevent sessions
from being written/read from!

Re: [PHP-DB] Sessions Vs DB Access
Don't forget that you can use the DB to store PHP Sessions as well, which is faster than storing the sessions in /tmp on the file system. If you have well written SQL, you can have 5-30 queries per page, most of which should return the data in under 1/100 of a second. I was running a site doing 150 queries per second, serving 1M page views a day. That's about 13M DB queries per day at a rate of about 11-12 page views per second. All on a dual 800mhz and 1gb of memory on FreeBSD, Apache, PHP and MySQL. It can be done!

[PHP-DB] imap_search problems
I'm writing a command line script to go through a mailbox on the file system. PHP the binary is compiled with imap, I've confirmed by using imap_headers to get the array of the 10,051 messages and printed the array out. Here's my code: #!/usr/local/bin/php -q Here's what I get when searching for a variety of different possibilities (no results being returned in $matches): Finding 'ALL fat' (Executing imap_search(Resource id #1,'ALL fat')) Finding 'ALL "fat"' (Executing imap_search(Resource id #1,'ALL "fat"')) Finding 'BODY "fat"' (Executing imap_search(Resource id #1,'BODY "fat"')) Then I put SE_UID as the last option in imap_search: Finding 'BODY "fat"' (Executing imap_search(Resource id #1,'BODY "fat"',SE_UID)) Finding 'TO "[EMAIL PROTECTED]"' (Executing imap_search(Resource id #1,'TO "[EMAIL PROTECTED]"',SE_UID)) I get nothing in $matches ever. What is going on? Am I doing it wrong? I've read the documentation and the contributed notes and copied and pasted replacing the search strings and continue to fail. Argh. I know the word "fat" is in the body of more than 50 messages, as well as in the headers, as there are 10,051 pieces of spam I'm trying to parse.

Re: [PHP-DB] imap_search problems
Don't you hate it when, right after you post to the list, you figure out
your problem? :-)
I removed the quotes around $id after using:
$err = imap_errors();
print_r($err);
to determine what the problem was.
Anyway, Happy Thanksgiving all, happy troubleshooting and never forget to use
the debugging tools the nice people at PHP gave you for Christmas.

[PHP-DB] Fulltext matching
Is there any way in PHP and MySQL to find out the most used words in a full
text index? Is there access to the index? In the index I want to show the
words that occur the most in descending order limit 50.
In addition, is there any way to search for, without boolean (using
3.23.??), words in a row? I've tried searching for "print pal" (which I
know exists) but only get print and pal returned as two separate words, and
since pal is 3 letters or less, it isn't indexed.
This doesn't work:
select id, match(body) against ('"print pal"') from body where match(body) against
('"print pal"');

[PHP-DB] Processing HTML forms
I have a form handler that I use that I wrote. It works great, but I have
a problem. I want it to save all the values from the forms when used with
PHP. For example, I have a text box that is named "data[phone][1][number]"
and I want the form to be automatically filled in for me. It works for the
first [] (ie data[stuff] gets filled in properly in my code).
Here's the code:
function displayText($name, $default = '',
$size = HTML_FORM_TEXT_SIZE, $maxlength = '')
{
if (preg_match("/^(.*)\[+(.*)\]+$/",$name,$x)) $setvalue =
$GLOBALS[$x[1]][$x[2]]; else $setvalue = $GLOBALS[$name];
$default = stripslashes((empty($setvalue))?$default:$setvalue);
if (!$maxlength) {
print "";
}
How would I write this to support multiple brackets? Basically it is the
preg_match line that does the "magic."

Re: [PHP-DB] Index on email or ID?
Something I used was this:
id | username | password | cookie_string
$foo = the id was rot13'ed then base64-encoded
$str = the cookie_string was an md5 hash generated at the time of registration
then a cookie was set:
setcookie("cookie_string",$foo."|".$str);
When the user returns, we checked for the cookie, and if it existed, split
on the "|", de-"crypted" (haha) the ID, looked up the cookie_string in the
DB and saw if it matched. If it did, it was pretty unlikely that it was
"hacked" so we logged them in.
