如何通过php函数来优化数据统计和报表生成？

$data = [1, -2, 3, -4, 5];
$filteredData = array_filter($data, function($value) {
    return $value > 0;
});

$data = [1, 2, 3, 4, 5];
$sum = array_sum($data);

$users = [
    ['name' => 'Alice', 'gender' => 'female', 'age' => 25],
    ['name' => 'Bob', 'gender' => 'male', 'age' => 32],
    ['name' => 'Cindy', 'gender' => 'female', 'age' => 28],
    ['name' => 'David', 'gender' => 'male', 'age' => 21]
];

$result = array_reduce($users, function($carry, $user) {
    $gender = $user['gender'];
    if (!isset($carry[$gender])) {
        $carry[$gender] = [];
    }
    $carry[$gender][] = $user['name'];
    return $carry;
});

$data = [
    ['name' => 'Alice', 'age' => 25],
    ['name' => 'Bob', 'age' => 32],
    ['name' => 'Cindy', 'age' => 28],
    ['name' => 'David', 'age' => 21]
];

echo '<table>';
echo '<tr><th>Name</th><th>Age</th></tr>';

foreach ($data as $row) {
    echo '<tr>';
    echo '<td>' . $row['name'] . '</td>';
    echo '<td>' . $row['age'] . '</td>';
    echo '</tr>';
}

echo '</table>';

$data = [10, 20, 30, 40, 50];
