Calculate Poker Hand - php

Question

My charity does "Poker Runs" motorcycle runs where player go to each stop and pick a card. We are looking to make this an easier way to track the winners without having to manually sort through each card.
I believe I have all other functions done, I just am unsure how to check for the full house with the method I am using. And also how to score just for a high card hand.
<?php
$card_one_suit = $_POST['card_one_suit'];
$card_two_suit = $_POST['card_two_suit'];

$card_two = $_POST['card_two'];
$card_three = $_POST['card_three'];
$card_four = $_POST['card_four'];
$card_five = $_POST['card_five'];
$player = $_POST['name'];

$rank = 0;
foreach($card_list as $card)
{
$count_values[$card]++;
}
foreach($card_suits as $cards)
{
$count_suit_values[$cards]++;
}
//echo "$count_suit_values[$card_one_suit]";

For the hand to be a full house, the array count_values must contain two entries, one of those entries must have a value of 3.
else if (count($count_values) == 2 && (array_values($count_values)[0] == 3 || array_values($count_values)[1] == 3)) {
echo 'FULL HOUSE';
}
