Hello,

I'm making a slot machine script, and I've done the simple part of seeing if each random spin matches eachother.

PHP Code:

if($spin_1 == 1 and $spin_2 == 1 and $spin_3 == 1){
$win_amount = 3;
} 


But now I want to see if $spin 1, 2 and 3 are equal to either 1, 2 or 3.
and set the win amount.

I have tried many things, including this:

PHP Code:

if ($spin_1 == 1 || $spin_1 == 2 || $spin_1 == 3 && $spin_2.. ect. 


Anybody help?

Lol, problem solved by a friend:

PHP Code:

$winnums = array(1,2,3);
    if(in_array($spin_1,$winnums) == true && in_array($spin_2,$winnums) == true && in_array($spin_3,$winnums) == true) { $win_amount = 500; } 


Just a thought...

As you probably already know the in_array() function will return a boolean value, so it can be used as a expression itself, instead of actually checking if it equals true. Of course, either way works just as good, but it may be a bit simpler to read this way.

PHP Code:

if (in_array($spin_1, $winnums) && in_array($spin_2, $winnums) && in_array($spin_3, $winnums)) {
   // ...
} 


And presuming that zero and negative numbers doesn't have a special meaning here, you could also just check if they're less than or equal to 3, like below. Again, either way works just as good, but perhaps this is evan simpler.

PHP Code:

if ($spin_1 <= 3 && $spin_2 <= 3 && $spin_3 <= 3) {
   // ...
} 


Nice post lizciz. As an added suggestion, this generalizes the whole routine and provides a bit more information:

PHP Code:

<?php
$winning_numbers = array(2,3,4);
$spins = array(2,3,4);

$num_spins = count($spins);
$num_wins = 0;
for ($i=0;$i < $num_spins;$i++) {
  $num_wins += (int)in_array($spins[$i],$winning_numbers);
}
echo '<p>'.$num_wins.' out of '.$num_spins.' matched</p>';
if ($num_wins == $num_spins) {
  echo "<h1>YOU'RE A WINNER!</h1>";
}
?>
