Here's how you can implement the logic in PHP:
### **PHP Code Implementation:**
```php
<?php
// Sample results array
$results = ["JS", "JC", "JD", "JH", "QS", "QC", "QD", "QH", "KS", "KC", "KD", "KH"];
// Function to simulate getting result based on gameId (for demo purposes)
function getResultBasedOnGameId($gameId) {
// This is just a placeholder. Replace with actual logic.
$gameResultMap = [
101 => "JS",
102 => "QC",
103 => "KD"
];
return isset($gameResultMap[$gameId]) ? $gameResultMap[$gameId] : null;
}
// Function to get the minimum bid amount result (for demo purposes)
function getMinimumBidResult($gameId, $jodiBids) {
$filteredBids = array_filter($jodiBids, function($bid) use ($gameId) {
return $bid[0] == $gameId;
});
if (!empty($filteredBids)) {
$minBid = array_reduce($filteredBids, function($carry, $item) {
return ($carry === null || $item[1] < $carry[1]) ? $item : $carry;
});
return $minBid[2]; // Return the result associated with the minimum bid
}
return null;
}
// Function to generate a random unique result based on last 2 results
function getRandomUniqueResult($lastTwoResults, $results) {
$possibleResults = array_diff($results, $lastTwoResults);
return $possibleResults[array_rand($possibleResults)];
}
// Main function
function determineResult($gameId, $jodiBids, $lastTwoResults) {
global $results;
// Step 1: Check if there is a specific result for the gameId
$result = getResultBasedOnGameId($gameId);
if ($result !== null) {
return $result;
}
// Step 2: Check if there is any Jodi bid for the gameId
$result = getMinimumBidResult($gameId, $jodiBids);
if ($result !== null) {
return $result;
}
// Step 3: Return a random unique result based on last 2 results
return getRandomUniqueResult($lastTwoResults, $results);
}
// Example Usage
$gameId = 104;
$jodiBids = [
[104, 100, "JC"],
[104, 50, "QC"],
[104, 150, "KS"]
];
$lastTwoResults = ["JS", "KC"];
$result = determineResult($gameId, $jodiBids, $lastTwoResults);
echo "Determined Result: " . $result;
```
### **Explanation:**
1. **getResultBasedOnGameId($gameId):**
- This function simulates fetching a specific result based on the `gameId`. You'd replace the `$gameResultMap` array with actual logic that fetches results from a database or other source.
2. **getMinimumBidResult($gameId, $jodiBids):**
- Filters the bids to those matching the `gameId` and returns the result with the lowest bid amount.
3. **getRandomUniqueResult($lastTwoResults, $results):**
- Excludes the last two results and picks a random result from the remaining possible results.
4. **determineResult($gameId, $jodiBids, $lastTwoResults):**
- This is the main function that checks the conditions in sequence and returns the appropriate result.
### **How It Works:**
- If there's a direct result tied to `gameId`, it's returned.
- If not, it checks if any bids exist and returns the one with the lowest amount.
- If neither condition is met, a random result is chosen, ensuring it's not one of the last two results.
This PHP function mirrors the logic you requested, providing a structured approach to determine the result based on the given conditions.
Code Adjustment for First-Time Scenario:
function determineResult($gameId, $jodiBids, $lastTwoResults) {
global $results;
// Step 1: Check if there is a specific result for the gameId
$result = getResultBasedOnGameId($gameId);
if ($result !== null) {
return $result;
}
// Step 2: Check if there is any Jodi bid for the gameId
$result = getMinimumBidResult($gameId, $jodiBids);
if ($result !== null) {
return $result;
}
// Step 3: Return a random unique result based on last 2 results
// If it's the first time and lastTwoResults is empty, pick any random result
if (empty($lastTwoResults)) {
return $results[array_rand($results)];
} else {
return getRandomUniqueResult($lastTwoResults
, $results);
}
}
$gameId = 104;
$jodiBids = []; // No bids
$lastTwoResults = []; // No previous results
$result = determineResult($gameId, $jodiBids, $lastTwoResults);
echo "Determined Result: " . $resu
