Question

I’m making a simple yahtzee script in PHP, I’ve got up the final point where it checks the 5 dice for a result at the end.

The 5 dice sides are stored in an array, example $dice (2,5,2,7,8)

I’m not that experienced in working with arrays, but is there easier ways to compare each number, to like find instances of 2 the same, 3 the same, all the same etc?

array_search() ?

Answer 1

array_count_values() might be a function that’s worth looking at. It will count the number of instances of a value in an array.

Example:

$dice = array(2,5,2,7,7);
$count = array_count_values($dice);

if($n = array_keys($count, 2))
{
    // 2 of a kind
    // $n = array(2, 7)
}

if(array_keys($count, 4))
{
    // 4 of a kind
}

if(array_keys($count, 2) && array_keys($count, 3))
{
    // Full House
}
