php - Check through an array and identify matching numbers -

-

i working on scratch card game user purchases scratch card me/my store , can redeem said card scratching off numbers , matching 3 pictures win prize

like physical scratch cards want prizes pre configured know when prize won, users dont, can limit prizes, not true random, random in terms of wins prize..

i know how setup prizes need check each data value in array ensure there not 3 matching numbers, unless have won..

so far have (i neaten , shorten code down soon)

$numbers = array(     0 => rand(0,9),     1 => rand(0,9),     2 => rand(0,9),     3 => rand(0,9),     4 => rand(0,9),     5 => rand(0,9),     6 => rand(0,9),     7 => rand(0,9),     8 => rand(0,9)     );

which randomly generates 9 numbers , 

echo "<table>";     $i=0;     for($x=0;$x<3;$x++){     echo "<tr>";        for($y=0;$y<3;$y++){            echo "<td>" . $numbers[$i] . "</td>";            $i++;        }     echo "</tr>";     }

sorts them 3x3 table

i know there command in_array() sort through array looking values dont want run endless loop checking each value see if match, because it's labor intensive , messy well.

i'm looking suggestion might have can sort through array , see if 3 numbers exist, if do, , they're not suppost (ie user hasn't won prize) 1 should changed new number.

so thank in advance guys forward suggestions

+more info

to pick winners use database query such this

$stock = $conn -> query("select distinct * codes available = 1 , 0 = floor(rand()*chance) order rand()");

each code have set chance win , if matches shown, depending on code won prize show 

$stock = $conn -> query("select distinct * codes available = 1 , win = 1);

'win' table in database each time plays game goes down 1

so each code have table win when hits 1 pop out in next game

these 2 ways can think of doing think work, both ways allow me control when , if wins second solution more accurate way of doing

how not changing number if triple 1 occurs, preventing triple 1 occurs.

function createscratchrange() {     $result = array();     $options = array_merge(range(0,9), range(0,9));      ($i = 0; $i < 9; $i++)     {         $key =  array_rand($options, 1);         $result[] = $options[$key];         unset($options[$key]);     }      return $result; }

and might want able create winners:

function createwinner() {     $winningnumber = rand(0,9);      $result = array();     $possiblenumbers = range(0,9);     unset($possiblenumbers[$winningnumber]);     $options = array_merge($possiblenumbers,$possiblenumbers);      ($i = 0; $i < 9; $i++)     {         $key =  array_rand($options, 1);         $result[] = $options[$key];         unset($options[$key]);     }      // looks random now.. no winning numbers... lets stick them in there.     $keys = array_rand($result, 3);     foreach($keys $key)     {         $result[$key] = $winningnumber;     }      return $result; }

and testing:

var_dump(createscratchrange());  // never give 3 identical numbers in array. var_dump(createwinner());  // give 3 identical numbers, never 2 sets of 3 identical numbers

How to calculate SNR of signals in MATLAB? -

-
i've encountered simple, yet fundamental problem on calculating snr: there several signals : s1 = original , pure clean signal without noise. n1 = white gaussian noise going added s1. s2 = s1 + n1 (the noisy signal before performing noise-reduction algorithm) s3 = noise-reduced signal (after performing noise reduction algorithm) n2 = s3 - s1 (the amount of noise after performing noise-reduction algorithm) now want compare snr before , after performing noise-reduction algorithm. which signals should consider snr_before!? s1/n1 or s2/n1 ? which signals should consider snr_after!? s3/n1 or s3/n2 ? which commands or functions should use in matlab in order compute snr_before , snr_after? thanks billion putting time on helping me. what know calculating snr before : snrbeforenoise = mean( signal .^ 2 ) / mean( noise .^ 2 ); and snr after : residual_noise = signal - noise_reduced_signal; snr_after = mean( signal .^ 2 ) / mean( residual_noise .^ 2...
