How can PHP be used to weight different results based on user responses?

To weight different results based on user responses in PHP, you can assign a weight value to each result and calculate a weighted average based on the user's input. This can be achieved by multiplying each result's weight by the user's response for that result, summing up these weighted values, and then dividing by the total weight. 

// Define results and their weights
$results = [
    'Result A' => 0.5,
    'Result B' => 0.3,
    'Result C' => 0.2
];

// User responses for each result
$userResponses = [
    'Result A' => 4,
    'Result B' => 3,
    'Result C' => 5
];

// Calculate weighted average
$totalWeight = array_sum($results);
$weightedSum = 0;
foreach ($results as $result => $weight) {
    $weightedSum += $weight * $userResponses[$result];
}
$weightedAverage = $weightedSum / $totalWeight;

echo "Weighted Average: " . $weightedAverage;
