Help with my daily 4 lottery game

[Monkuar]

Okay, users can select numbers:

 

0000 to 9999

 

I already finished to check inputs serverside.

 

 

The problem is let's say I have:

 

1413,1812,2325,2326,2623,3236,3738,3932,5156,6169

 

 

 

Now,  that is USER JOE.  If USER Joe picks those numbers, I will need to find out the following:

 

 

*Match 4 numbers in the correct order win <b>100%</b> of the jackpot. (Odds: 1 in 10,000)<br>
*Match 2 numbers in the correct order win <b>40%</b> of the jackpot. (Odds: 1 in 833)<br>
*Match 4 numbers in the wrong order win <b>20%</b> of the jackpot. (Odds: 1 in 417)<br>

 

And the correct number, let's say is "8521";

 

 

 

So what kind of php functions should i be dealing with here? I will need to foreach seperate them

 

$numbers = "1413,1812,2325,2326,2623,3236,3738,3932,5156,6169";

foreach(explode(',', $numbers) as $num_set)
{


//Need to find how to match my 8521 with the numbers here



}

 

Long story short, I will be extracting this data from my MYSQL table called "daily4_tickets" and it will have rows of data for all my users with their chosen numbers.  Hope I am going in the right place,

 

I know i need to use some type of array_key matching, need some help to move me into the right direction,

 

thank you

Hey, i never really touched php classes/etc so it's honestly like a whole new ball game, hehe.

 

I really look at that code like a new life cuz I don't really understand the top half of it all, im more of a old fashion php kid, so i apologize.

 

guess it's time to learn though right?

 

 

Thanks for it and i'll use it to the best of my knowledge, lol

 

im currently extracting this:

 

 

$query = $db->query("SELECT l.*,m.id,m.username,m.star FROM daily4_tickets as l
							LEFT JOIN users m ON (m.id=l.user_id) ORDER BY date ASC") or error('Unable to send the message.', __FILE__, __LINE__, $db->error());

$winning_number = 1992;

			while($dailycheck = $db->fetch_assoc($query)) {

$tickets[$dailycheck['user_id']] = explode(',', $dailycheck['numbers']);



		var_dump($tickets);
		//Check if a user matched a Ticket
		if (in_array(1992, $tickets[$dailycheck['user_id']])) {
		$winninguser_ids[] = $dailycheck['user_id'];
		}

//Check if a user matched 2 numbers in order
//???

//Check if a user matched all 4 numbers but not in order??
//??? 

}
echo implode(",", $winninguser_ids);

 

 

I will incorporate your code or try too once iget around with it,

 

my var_dump is

array
  271 => 
    array
      0 => string '1413' (length=4)
      1 => string '1812' (length=4)
      2 => string '2325' (length=4)
      3 => string '2326' (length=4)
      4 => string '2623' (length=4)
      5 => string '3236' (length=4)
      6 => string '3738' (length=4)
      7 => string '3932' (length=4)
      8 => string '5156' (length=4)
      9 => string '6169' (length=4)
      10 => string '6264' (length=4)
      11 => string '7873' (length=4)
      12 => string '8586' (length=4)
      13 => string '9497' (length=4)
      14 => string '1992' (length=4)
array
  271 => 
    array
      0 => string '1312' (length=4)
      1 => string '2527' (length=4)
      2 => string '5451' (length=4)
array
  271 =>

      0 => string '7071' (length=4)
      1 => string '8184' (length=4)
array
  271 => 
    array
      0 => string '2528' (length=4)
      1 => string '8089' (length=4)
array
  271 => 
    array
      0 => string '6789' (length=4)
array
  271 => 
    array
      0 => string '6789' (length=4)
      1 => string '8987' (length=4)
array
  271 => 
    array
      0 => string '6789' (length=4)
array
  271 => 
    array
      0 => string '7654' (length=4)
array
  271 => 
    array
      0 => string '7654' (length=4)
  106 => 
    array
      0 => string '2421' (length=4)
      1 => string '1992' (length=4)
271,106

 

so im kinda on the other road as your script atm, but like I said, i will save it and use it once I get setted in on php CLASSES and stuff.

 

right now, I just need to know how to differentiate between matching only 2 numbers in order and 4 all correct but in the wrong order.. hehe
