$c = ($num % 1000) / 100; //$c will be equal to 1.55
$x = ($num % 100) / 10; //$x will be equal to 5.5
$i = $num % 10; //$i will be equal to 5

$m = (int) ($num * 0.001); $num -= $m*1000;
$c = (int) ($num * 0.01); $num -= $c*100;
$x = (int) ($num * 0.1);$num -= $x*10;
$i = (int) ($num);
// echo m = $m, c = $c, x = $x, i = $i ;

. RomanDigit($c, 'C', 'D', 'M')
. RomanDigit($x, 'X', 'L', 'C')
. RomanDigit($i, 'I', 'V', 'X')
);
}
?
and my test script:
?php
include(to_roman.php);
$test = array( 8, 19, 155, 980, 9.8, -3, 3999, 4000, abc, , array() );

I dont know if this is possible in PHP (Newbie) im working on a project where each product has 3 diffierent prices depending on the amount sold so say for example 1- 100 price A 101-299 price B and above 300 Price C. What I need to be able to do is increment an mysql database field each time an item is sold then look at that field to decide which price variable to write to the price field of the database. Could someone point me in the right direction where I could solve this or to someone who could First, how are you storing the price points? I would consider a separate pricing table linked to the item table like so: table ItemForSale id integer auto_increment name varchar(30) descr varchar(200) table PricePoint id integer auto_increment item integer ordersize integer priceper float then for a given item and number of items ordered, you can retrieve the applicable price-per by SELECT priceper FROM PricePoint WHERE item=$itemID AND ordersize=$number ORDER BY ordersize DESC LIMIT 1 Each item can have an arbitrary number of price points at any number-of-items. Note that this assumes the priceper always decreases with increasing ordersize for a given item. Second, I don't understand why you reset the cumulative price-point every time you process an order; for selling, surely the price- point only applies to a single order rather than cumulatively, and for purchasing or reporting, I would expect to calculate it dynamically at the time the report is generated.

I need to create some kind of 10 digits serial number where I can generate

How many unique values do you need, and how hard-to-fake?
I would consider something like 7+3 digits - the first seven digits
are generated more or less randomly, and the last three are
checksums... this gives you 10 million valid combinations, and
a one-in-a-thousand chance of any random number being valid.
Obviously, the quickest way to increase security is to increase
the number of digits.
Each checksum can be any formula you can imagine, for example
// Expects:
// d (digits) - array [0..6] of integer in [0..9]
function checksum1($d) {
// scrambler array
$s = array( 24, 78, 63, 501, 88, 89, 53, 14, 34, 266 );

I will assume it removed from tbl_student_history_answers. There are two ways of factoring this, depending on exactly how you plan to use it. If you will always only want questions 19 and 20, you can hard-code those into a per-student query, like so: SELECT tbl_student_details.student_id, tbl_student_details.name, tbl_q19.p_answer AS a19, tbl_q20.p_answer AS a20 FROM ( tbl_student_details JOIN tbl_study_mode ON tbl_student_details.study_mode=tbl_study_mode.id) JOIN tbl_student_history_info AS q19_info ON tbl_student_details.id=tbl_student_history_info.student_id) JOIN tbl_student_history_answers AS tbl_q19 ON q19_info.answer_id=tbl_q19.id) JOIN tbl_student_history_info AS q20_info ON tbl_student_details.id=tbl_student_history_info.student_id) JOIN tbl_student_history_answers AS tbl_q20 ON q20_info.answer_id=tbl_q20.id) WHERE tbl_study_mode.txt_study_mode='Full Time' AND q19_info.question_id=19 AND q20_info.question_id=20 This is actually a poor way of doing things, but it makes your final PHP code much simpler. If you will ever want to use this query to look at answers to a different number of questions - say, questions 19, 20 and 21 - you would be better to do a per-student/per-question query, like so: SELECT tbl_student_details.student_id, tbl_student_details.name, tbl_student_history_info.question_id, tbl_student_history_answers.p_answer FROM ((( tbl_student_details JOIN tbl_study_mode ON tbl_student_details.study_mode=tbl_study_mode.id) JOIN tbl_student_history_info ON tbl_student_details.id=tbl_student_history_info.student_id) JOIN tbl_student_history_answers ON tbl_student_history_info.question_id=tbl_student_history_answers.id) WHERE tbl_study_mode.txt_study_mode='Full Time' AND tbl_student_history_info.question_id IN ( 19, 20 ) ORDER BY tbl_student_details.student_id ASC, tbl_student_history_info.question_id ASC This will return several records per student, one for each question you want to know about; the ORDER BY is useful to make all records for a single student consecutive so your PHP code can process it easily.

[PHP-DB] Re: Newbie attack...
Everything is working great except the fact that when I put some php code into the 'text' field, in order to run en extra sql command in the page, it hangs and just prints the code as if it was just text. (shrug) so far as the database is concerned, it *is* just text. If you want returned code evaluated, you will have to explicitly evaluate it. Possible approaches: 1. Search for php code in your content: split the string appropriately and evaluate as needed. I would avoid this because it's a lot of extra work, and because it's quite possible to write 'interleaved' PHP code that requires several blocks working together; evaluating a single block at a time will just get you errors. 2. Evaluate all your content. You would have to be very careful about letting people contribute content, and it might be a bit slower; but it's very very simple. 3. Have markers in your content, referring to PHP code from another table. Would be a bit slower (have to do multiple queries to retrieve code as needed), but more secure - people can safely contribute to the HTML content table, you can let them reference standardized PHP fragments. 4. Half-way between #2 and #3: add a flag field to your database table, if the flag is set the content must be evaluated, otherwise it is plain HTML and can just be echoed. People can contribute content, but the flag stays off until you double-check any PHP code for safety. -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP-DB] Re: viewing records
he will have access to the first record, which I'm displaying in a form. My question is: can another user view the same record at the same time? It depends entirely on where and how you get the data. Of itself, there is nothing to prevent the same record being displayed to any number of users. if the answer is yes, is there any way to prevent this? It is possible, but I am not at all certain it is the right thing to do... I would be more concerned about data corruption, and a better way to prevent that is to keep a copy of the original data and compare it to the 'official' version before updating. This way, any number of people can view the record, but only one can update it; anyone who tries updating it after that can be warned and prompted to modify their own data appropriately. This also avoids problems with people locking records and then leaving, or leaving their browser at the page for 6 or 8 hours during which time no-one else can access that record. -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Here's an easy one that I can't find laid out for me anywhere:

i need this result:
1 2

2 3
3 2
3 1
clear enough?
Uh... haven't tested it, but seems likely:
SELECT a.id, b.id FROM mytable AS a JOIN mytable AS b ON a.id != b.id
1. this could easily return a very VERY
large result.
2. are {1,3} and {3,1} really different,
or should you use ...ON a.id b.id ?
This would cut the size of your returned

3. there are probably much better

[PHP-DB] Re: Database search question
How can I accomplish the following? I have a table called search, I have 3 fields, city, country, type I also have an imput box where you can type in a search word. What I need is, say you type in hotels germany, I need the search to break up the sentence and then search each 3 fields in the DB looking for a match. So, for example: it would find hotels in type and germany in country, see that they belong together and then display those results - how can I do this? I know I need to splitup my search phrase into individual words to search, but i'm stuck. Two possible approaches spring to mind: 1. Search all three categories for each keyword, ie 'hotel germany' would turn into SELECT * FROM mytable WHERE (country='hotel' OR type='hotel' OR city='hotel') AND (country='germany' OR type='germany' OR city='germany') 2. A translator table: two text fields, 'phrase' and 'search', filled with something like: phrase | search 'germany' | 'country=\'de\'' 'states' | 'country=\'us\'' 'brazil' | 'country=\'br\'' 'hotel' | 'type=2' 'bed' | 'type=1' 'b\b' | 'type=3' 'london' | 'city=31854' 'paris' | 'city=22059' ... you can then use a search through the translator table to build the select statement that actually does the query. Both of these have drawbacks, mainly that the tables they nominally reference are severely non-normalized; I suspect the proper approach should be a series of queries for each term among a set of normalized tables, followed by a final constructed query... but you get the idea. Another point: single-word searches could be a problem, stumbling over 'New York' or 'bed breakfast'; it might be worth amending the search to also try consecutive-word pairs. -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

So your PHP should do something like

You would have to parse the HTML file, extract the names of all the images (and CSS files, applets/ActiveX components, and javascript/vbscript inclusions) called, fully qualify the names, remove duplications (which would be served from the client's cache), request the files and check their sizes, then add it all up with some additional time for each request. Alternatively, you could wave your hands and come up with some sort of fudge factor; if you want to be a bit more accurate, set your super-complete-script to try a couple thousand random URLS and scatter-plot the results, HTML-only page size vs. total page size - less reliable but far simpler and faster. If the result is within 20% for 80% of the time, I would be happy.

// The FALSE is a dummy term so I don't

I don't like the sample code given because it just

depending on what you're replacing with what, a solution is eregi_replace.
I
do not advice to upper nor lowercase the source as it will change parts of
data unwantedly.
Yes, I agree; another solution is as follows:
function alt_str_replace($search, $replace, $subject) {
// Temporary copies of search string and subject string;
// both shifted to lowercase to make the search case insensitive.
$t_search = strtolower($search);
$t_subject = strtolower($subject);
// Initialize result string
$res = ;
// Initialize search vars
$search_offs = 0;
$shift = strlen($search);
// As long as another match is found...
while (($t = strpos($t_subject, $t_search, $search_offs)) !== false) {
// Copy non-matching portion of string
$res .= substr($subject, $search_offs, $t-$search_offs);
// Add replacement value
$res .= $replace;
// Update search offset
$search_offs = $t + $shift;
}
// Add trailing end of string
$res .= substr($subject, $search_offs);

Just reload the page using the header function:
Once submit has been hit in one frame, pass a hidden value from Frame1
to frame2:
input type=\hidden\ name=\refresh\
Then detect for it in the 2nd frame and refresh the page using the
header() function:

When the form is submitted, it calls the target

Cato Larsen [EMAIL PROTECTED] wrote in message
[EMAIL PROTECTED]">news:[EMAIL PROTECTED]...
Just to have said it... Im green in both PHP4 and MySQL.
Can anyone say what I've been doing wrong here, and how to fix it, or even
better. Debug the whole shit! =)
First, make sure PHP is actually running.
Try this:
?php
$str = PHP is not running!;
echo substr($str, 0, 7) . substr($str, 11);
?
For one thing, trying to echo unescaped double-quotes
won't work, ie
echo table leftmargin = 0;// no good!
Use ' or \ instead.
Second, all this variable-renaming seems like a waste
of effort; just use the array directly.
$cid = mysql_connect($host,$usr,$pwd);
if (!$cid) { echo(ERROR: . mysql_error() . \n); }
If the connection fails, your script prints an
error message, then continues trying to query...
if (!$cid) {
echo Error: .mysql_error();
exit;
}
... or redirect them back to a different page.
# setup SQL statement
$SQL = SELECT * FROM memberinfo ;
$SQL = $SQL . WHERE prof = '$prof' ;
$sql = SELECT * FROM memberingo
.WHERE prof='$prof' ;
echo (PDTBMembers who are $prof s/BBR\n);
dt should only occur in dl.../dl
$apperiance = $row[apperiance];
'appearance'
$prof = $row[prof];
? you already know prof; why query for it?
First thing to do is write a couple of
functions to take care of the formatting
for you:
// Generic tag-formatting routine
// Ensures all tags are closed properly;
// Also forces you to think about tag-clause formatting
//so the final result is readable.
function clause($preopen, $tag, $opts, $pretext, $text, $preclose) {
return $preopen$tag $opts$pretext$text$preclose/$tag;
}
function table($contents) {
return clause(\n, table, style='margin-left: 80px;', ,
$contents, \n);
}
function row($contents) {
return clause(\n\t, tr, style='margin-top: 30px;', ,
$contents, \n\t);
}
function cell($text, $width=0) {
if ($text == )// check for empty str
$text = nbsp;;
$opts = ($width 0 ? style='width: $widthpx;' : );
return clause(\n\t\t, td, $opts, , $text, );
}
function bold($text) {
return clause(, b, , , $text, );
}
I would simplify your table, too, at least until
you get it working; play with it after that.
$contents = row(cell(, 150) . cell(, 200) . cell(, 200));
while ($row = mysql_fetch_array($retid))
$contents .= row(
cell(img src='{$row[picurl]}')
.cell(
bold(
{$row[tit]} {$row[charname]}
.quot;{$row[charnick]}quot;
.{$row[charsname]}
).br
.bold(Contact: ).$row[email].br
.bold(Level: ).$row[lvl].br
.bold(Breed: ).$row[breed].br
.bold(Profession: ).$prof.br
.bold(Location: ).$row[loc].br
.bold(AIM: ).$row[aim].br
.bold(ICQ: ).$row[icq].br
.bold(MSN: ).$row[msn].br
.bold(Yahoo!: ).$row[yahoo].br
)
.cell(
br
.bold(Born: ).$row[born].br
.bold(Appearance: ).$row[appearance].br
.bold(Position: ).$row[posn].br
.bold(Characteristics: ).$row[charac].br
.bold(Strengths/weaknesses: ).$row[streng].br
.bold(Bio: ).$row[bio].br
)
);
echo table($contents);
(Note: this approach builds the whole table in memory, in order
to print it out using the clause() function; it might be worth breaking
that out and printing the table a row at a time if there are
many rows in the table.)

Koutsogiannopoulos Karolos [EMAIL PROTECTED] wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... I wan't your opinion regarding a program i am constructing. It is about an image bank for graphic studios or anyone else who needs a program that can insert his pictures or descriptions of it and be able to make a fast and reliable search. http://www.hotscripts.com/PHP/Scripts_and_Programs/Image_Galleries/more2.htm l What would be best.? Inserting the pictures in the DB or in the file system I would keep the image name in the database; save the original image in a dedicated directory with a numeric name like 4920185.jpg and then the thumbnail either with a suffix (like 4920185b.jpg) or with the same name in a thumbnails directory; store the number as the picture ID. The numbers should be large and pseudorandom, ie you don't want to make it easy for someone to write a script to leech all your pictures (it'll still be possible, but harder). Maybe use the database ID to seed a random number generator, and use the Nth generated number? Have a text field for keywords, a text field for description, a price field?, the author's name, email, and homepage. If you put the image directory below the web root directory, then the images can only be accessed via a script, and you can restore the original name at download (this solves the problem of name collisions). If you're going to sell the pictures, you should allow a buyer more than one download, in case they screw up or accidentally delete it on their system; I would have a table for 'current purchases' with a buyer ID and picture ID, and allow them something like access for a week, up to 20 downloads of that image. ? Also notice that it is a reference db and not an actual bank. I mean that there will be only photos of low quality and not the full picture which could be very large.

Your query is mixed up; 'test' is the field name, not the table name, and I
think you want to put the values into three separate records, not one...
Try
INSERT INTO tablename ( test ) VALUES ( 'a' ), ( 'b'), ('c'), ('');
This should get you four records, with 'test' values of a, b, c, and null.
If you want to store more than one value in the same record, you should be
looking at sets, not enums.

Noah Spitzer-Williams [EMAIL PROTECTED] wrote in message news:[EMAIL PROTECTED]... i have two tables each with a same field and i would like to find which table has the bigger value in this field.. is there a way to do this with one select statement? i've tried things like: select max(t1.bannerid) as b, max(t2.bannerid) as a, IF(t1.banneridt2.bannerid,t1.bannerid,t2.bannerid) FROM user_banners as t1, user_banners_approve as t2 ORDER BY t1.bannerid DESC GROUP BY t1.bannerid but im not having much luck. Uh... either do a separate select for each table, or find a way to JOIN the tables? Better than that, if you're doing what it looks like you're doing - keeping two separate tables, one for approved banners and one for non-approved one? - make a single banners table with an 'approved' field... then it's simple. -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]
Re: [PHP-DB] most efficient weighting system? URGENT
How many rows are you likely to have, and how dynamic are the weights? I think I'd add a cumulative sum column to your table, ie idweightcum_weight 11010 25 15 3318 42038 5240 then $query = SELECT id FROM table WHERE cum_weight = .rand(1,40). ORDER BY cum_weight LIMIT 1; Note that if you delete or update any row, the cumulative values become incorrect. It would be better to calculate cum_weight dynamically, but I'm not sure how; also, this could be computationally expensive. Another way to do this would be to repeat each row the appropriate number of times, ie id value 11 21 31 ... 101 112 122 ... 152 163 173 183 194 204 ... 374 384 etc. Then you could use $query = SELECT value FROM table ORDER BY RAND() LIMIT 1; Noah Spitzer-Williams [EMAIL PROTECTED] wrote in message 9hilnk$9pp$[EMAIL PROTECTED]">news:9hilnk$9pp$[EMAIL PROTECTED]... if i have several rows in a table and i want some to have certain weights what is the best way to pick a random row based on its weight? ex of table: idweight 1 10 25 33 420 52 therefore, since there is a total weight of 40, id 1 should be picked 25% (10/40) of the time, id 4 50% (20/40), etc... what is the best way to do this? -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]

Subject: Re: [PHP-DB] Passing XML
Is this what you have in mind?
$url = 'http://website.com/document.xml';
$str = implode('', file($url));
$str = contains the xml doc and retains formatting
$url could be a doc on the local server as well.
Sure, that would be one way to implement option #1; or, as in the XML entry
in the PHP manual, paging through the file in 4k chunks (better if you're
parsing large files); but passing the url as a parameter instead of defining
it explicitly, ie
http://myserver/script.php?url=http%3A%2F%2Fwebsite.com%2Fdocument.xml
Or you could post the whole XML source to the script (this could be useful
for interactive testing of an XML-generating script); or you could upload an
XML file and have the script parse it (I'm really not sure how this would be
useful, but you could :-)
Also note, if you want to get XML back again, maybe you should look at the
XSLT functions.
--- Hugh Bothwell [EMAIL PROTECTED] wrote:
I'm not sure how you mean; it depends on where the
data is coming from.
I count three ways you can do this:
1. pass the XML filename (or URL) to the script via
GET or POST
2. pass the XML source to the script via POST
3. upload the file via POST and call the script
More details on what you're trying to accomplish
would help.

Hi there
Is there anyway of passing a xml document to a php
page as raw data.
What I want to do is eg.
send a page a xml document and recieve a response
( in xml ) from that page.

Re: [PHP-DB] Executing several PHP scripts simultaneously??
Consider using set_time_limit() before each sub-script executes; this will time out on any individual script, but let you extend the limit on the master script. Lisa Elita [EMAIL PROTECTED] wrote in message 004901c0ffd5$90c63680$a6fc2bca@telkomnetnstan">news:004901c0ffd5$90c63680$a6fc2bca@telkomnetnstan... How can we execute several PHP scripts simultaneously inside a single PHP script? For example, let's say master.php has 10 tasks in different PHP scripts: 1.php, 2.php, ..., 10.php. Each task is independent (the input of each task is not determined by other tasks) so we can do the tasks in any order. But if 2.php is initiated after 1.php is done, and 3.php is initiated after 2.php is done, and so on, the master.php can be expired, causing the remaining tasks not executed. So how can we execute these PHP scripts simultaneously?

Re: [PHP-DB] Which state and country?
Um... you could look at REMOTE_HOST to get their IP address and use that to look up the address of their server. If you assume they won't log in long-distance, that should give you their country and state, and maybe a useful approximation of their city.
