How can PHP functions be optimized to efficiently process arrays with complex structures and multiple conditions?

To optimize PHP functions for efficiently processing arrays with complex structures and multiple conditions, consider using array functions like array_filter, array_map, and array_reduce. These functions can help streamline the code and improve performance by handling array manipulation tasks more efficiently. 

// Example code snippet demonstrating optimization of processing arrays with complex structures and multiple conditions

// Sample array with complex structure
$users = [
    ['name' => 'Alice', 'age' => 25, 'active' => true],
    ['name' => 'Bob', 'age' => 30, 'active' => false],
    ['name' => 'Charlie', 'age' => 20, 'active' => true],
];

// Filter users based on multiple conditions
$filteredUsers = array_filter($users, function($user) {
    return $user['age'] > 20 && $user['active'] === true;
});

// Map the filtered users to a new format
$mappedUsers = array_map(function($user) {
    return ['name' => strtoupper($user['name']), 'age' => $user['age']];
}, $filteredUsers);

// Reduce the mapped users to calculate the average age
$totalAge = array_reduce($mappedUsers, function($carry, $user) {
    return $carry + $user['age'];
}, 0);
$averageAge = $totalAge / count($mappedUsers);

echo "Average age of active users above 20: " . $averageAge;
