PHP - Random Prize Assign Based On Percentage Win Rate
Hi all,
I am building a random prize assigner function based on weighted percentages.
I am able to assign a basic true/false weighting but am struggling to form a way of selecting an array based prize based on the win rate.
Heres my current code:
function selectPrize() {
$prizes = array(
0 => array(
'name' => 'Top Prize',
'rate' => 50
),
1 => array(
'name' => 'Middle Prize',
'rate' => 30
),
2 => array(
'name' => 'Bottom Prize',
'rate' => 20
),
);
// oops
}
selectPrize();
Could somebody please give me pointers on how i could approach this?
Thanks.
Edited by biggieuk, 19 June 2014 - 05:14 AM. Similar TutorialsHi My website is a Wordpress WooCommerce. I modified the PHP function that worked well before I added the multiple customer roles. I have regular customers and regular and tier-level wholesalers. I live in Canada and with have two taxes to apply (GST & PST). We also have customers/wholesalers that get exempted from one tax (PST) only or both taxes. I have one regular wholesale role with two tax exemption roles: 'wholesale_customer', 'wholesale_pst_exempt', 'wholesale_tax_exempt'. I have 4 tier levels wholesale roles with each their own tax exemption roles: 'wholesale_silvia_silver', 'wholesale_silvia_gold', 'wholesale_silvia_premium', 'wholesale_silvia_union' 'wholesale_silvia_silver_pst_exempt', 'wholesale_silvia_gold_pst_exempt', 'wholesale_silvia_premium_pst_exempt', 'wholesale_silvia_union_pst_exempt' 'wholesale_silvia_silver_tax_exempt', 'wholesale_silvia_gold_tax_exempt', 'wholesale_silvia_premium_tax_exempt', 'wholesale_silvia_union_tax_exempt' The tier levels are new and I'm trying to update my existing function that applies different tax rates based on customer user roles. I also have filters to alter the shipping tax for the different tax class based on the customer role. Here are the function and filter that I have updated to add the additional tier level wholesale roles. The changes I've made are not working because I don't see the tax exemptions. Both taxes are always being applied. Can someone help me figure out what I've done wrong to the code that stopped it from working? I'm not proficient in PHP, so was trying my best to make this work.

Hello guyz, Well i am storing some files on my server, i want only members to be able to download files. these are what i want to do : I should have an initial URL like this : "http://mysite/file/{file_id}/filename.mov so i will be checking to see if member is logged in, if yes then it should generate a temporary id which will expire within 1 day and start the download automatically! I have coded the user class which checks if its logged in, and i am generating the id, but the problem is how to show the final file url like this : http://mysite/file/{sha1 or something very random}/filename.mov and let it to be downloaded. thanks Hello. I have written this script where user restaurant owner can add his place to the database of all local restaurants. (insert basic information into database, add up to 3 images, thumbnail creation, insert image information to database). It works well on localhost, but i would like some suggestions for improvement. Im not very sure of its structure, it may not execute well once it is online. And i also think there are too many "IF's". But i really have no idea how to do it any other way. Thanks for all the suggestions.

How do you establish a tax rate in a MySQL database to use in a form calculation, then be able to change the value to a new constant value from the form? Php Folks, I started learning php originally from 2015. On & off. Part time. Started getting into it seriously around 2017. From home. No classes. From forums and php manual and tutorial sites. Still at oop & mysqli. Had ups & downs as first learnt a lot of old stuffs then found out they been deprecated. For example, if I had originally known pdo is modern over mysqli then I would started on pdo from beginning. Got no real guidance anywhere. Just learnt things the hard way, coming across obstacles and bugging forums. Half-way learning mysqli I come across pdo. So you see, if I had taken school classes then they would have started me on the new stuffs. But because I learning from home, I came across a lot of old tutorials and started from there without knowing they are sort of outdated stuffs. Anyway, I don't like quitting half-way and so did not quit mysqli for pdo when a lot of programmers advised me to dump mysqli for pdo. Thought, since I "wasted time" on mysqli then might aswell build a few sites with it before ditching it. Part time study. Full time working on projects for 3yrs now. projects are own "hobby sites" so to speak and not for clients. I am not the freelancer type or professional type. layman type. Never really have launched any sites. I finish one site/project then move onto another project for learning purpose. So I learn very little then moving onto building sites based on what little I learnt. When I learnt how to use the SELECT, INSERT. DELETE, UPDATE in sql, I jumped into learning to build my own membership site (reg, log-in, logout, etc. pages) to deal with mysql db. So far, built membership parts (login, logout, account homepage, pagination). All by copying codes from tutorials and forums from people like you and changing here and there according to my needs. And when I get stuck. I bug programmers like you. I do have a conscious and do not like plagiarism even while learning and so everytime I copy paste codes from tutorials or forums (where I get help), I retype every line and then delete the copy-pasted lines and leave my typed lines in the file. that way, I feel good I atleast made some effort to build the site rather than copy & paste. Then, I change the codes here and there to suit my purpose. Don't you like me ? ;). You probably chuckling inside reading this. Here's an example of how I copy-paste then re-write the lines.

One thing I gain from this type of re-writings is that, typing the same thing over and over again sort of gets codes sink into my subconscious. Helps to memorise the codes. Ok. So now you know a little about me. As you can see, I always start on somebody else's skeleton, be it from a tutorial forum or a tutorial site or php manual. I have completed 3 websites, so to speak, in that way. 2 days ago I thought, I been doing this for 3yrs now. Let's test and see how well I can code without working on somebody else's skeleton. No copy-pasting from forums or tutorial sites or php manual. And so, look what I did. I coded all the following from my own memory. let me know how well I did. That repetition of lines re-writing has done me some good to memorise codes. I did make 2 mistakes. Note the comments in the code. You will notice "MY CODE ..." and then a correction "WHAT IT SHOULD BE ...". Compare the 2 and see how close or far away I was from the correction. And then give me score from 1-10 (where 10 is best) how well I did as a home study middle aged guy. Hard learning things at middle age. I think, if I had toild you I started learning a month ago then you'd give 9/10 but because it's been 3 yrs, you'll give 1/9 or 0. Just bear in mind it's not easy to learn things at middle age and remember them without forgetting. I learn fast but forget double fast. Lol! One thing though. My codes are not working. They do not INSERT data into db nor extract & display data from db. What is wrong ? TEST NUMBER 1: On this one, I first tried displaying data rows from mysql using mysqli_stmt_get_result(). That failed and so I tried with mysqli_stmt_bind_result() afterwards and so bear that in mind and don't ask me why I used both instead of one. Clicking the "search" button gives no response. Nothing happens on page. I did search for a ketywords that exist in each mysql tbl columns.

Hi, am trying without much luck, (I am new), to define an exchange rate on the page and then mutiplying it by a value I am extracting from a mysql db. I write the value as below normally but having trouble writing this entry and multiplying it by my defined exchanged rate of say 2.22. <?php if(!empty($row['Band_1_Price'])) {echo "<div class=pricing_box_right2>£".$row['Band_1_Price']."</div></div>"; } ?> Thanks so much. Hello guys, I am new to PHP programming. I am trying to figure out how to use PHP language to transmit/write characters to a USB port device at 9600 baud rate 8-N-1. Basically I just need the PHP coding to allow me to send stuff to the USB device but I have no idea how I can interface this. I did some researching but most were for RS-232 COM Port. I can't find the proper one for USB. If someone can help me out, that would be awesome. Thank you! As above, I have a lottery style site that picks a random number between 1-8 but my users complain for some reason that this is not enough. So i was told to look into using fopen and random.org to generate a random number. Anyone have experience of this and perhaps a code snippet for me to look at and possibly use? help will be appreciated. I have made a 'health bar' for a simple browser game i have been working on.
I want to use a background image to fill the health bar, so if for example, the player had full health, the health bar image width would be 100%
is it possible to say set, the characters max health and the characters actual health and work it out as a percentage so i can stretch the image width as far as it needs to go?
sorry if i haven't been too clear, my understanding of maths is not so good.
Thanks for any tips.
hey guys is it possible to have an output that will echo a percentage between 2 tables? like students vs detentions would give like 45%.. I have a scratch ticket system I made, and this code generates if a user will win or not. Code: [Select] $card1 = rand(1,5); $card2 = rand(1,5); if($card1 == "1" && $card2 == "1"){ //I WON!!! do my queries here/etc }else{ //Failed } Okay, now how can I make it so I can set it up so I can change it to 5% of winning, 10% of winning, 15% of winning, 20% of winning/etc so on? instead of just a random count function? Hi,
I basically want a function that takes a parameter which is a percentage chance of the functioning returning true.
A user can move from tier 1->10 and at tier 1 there's a 70% chance to move to tier 2, from tier 2 there's a slightly less chance to move up, and so on.
I tried with the following piece of code:
public function rollTheDice($winnerPercentage)
{
$number = rand(1, 100);
if ($number <= $winnerPercentage)
return true;
return false;
}
The above code makes logical sense to me:
1. Pick a random number between 1 and 100.
2. If that number is less than or equal to the percentage, then we passed (example, if the random number is less than or equal to 70.. there must be a 70% chance of this?)
This however does not seem to work, in fact it appears that when simulating a roll, 70% fails at the very first step (where there is a 70% chance of winning..)
To actually make it to tier 10, has yet to be accomplished, so by simulating this with unlimited attempts for 120 seconds straight doesn't seem to "win".
I tried (just for fun) and change the if-statement so:
if ($number >= $winnerPercentage)
This seems to be working quite well, as the simulator quickly reaches tier 10 this way.
Any suggestions to code changes, or can someone explain why it is working way better when exchanging less than with greater than?
Hello In my query i have x activities, then i have the count of how many still to be executed, i need to get the percentage of the total executed I mean i have 200 activities, 20 have been executed, so i want to have 10% done My query is this one but missing the percentage field
SELECT COUNT(*) AS total,
IFNULL(SUM(CASE WHEN (t1.dataPrevista >= CURDATE() OR ae.Fim <= CURDATE()) THEN 1 ELSE 0 END),0) AS exec
FROM atividades AS t1
INNER JOIN anosescolares AS ae ON (t1.`idAnoEscolar` = ae.idAnoEscolar)
WHERE ae.Estado = 1;
any help? |
