How can PHP code be optimized to improve performance when handling large amounts of user data for statistical analysis?

To optimize PHP code for handling large amounts of user data for statistical analysis, consider using efficient data structures like arrays or associative arrays, minimizing database queries, and utilizing caching mechanisms to reduce redundant computations. 

// Example code snippet using arrays to optimize performance
$userData = []; // Initialize an empty array to store user data
// Loop through user data and populate the array
foreach ($users as $user) {
    $userData[$user['id']] = $user;
}

// Perform statistical analysis on the $userData array
// Example: Calculate the average age of users
$totalAge = 0;
foreach ($userData as $user) {
    $totalAge += $user['age'];
}
$averageAge = $totalAge / count($userData);
