How can restructuring data structures improve the code efficiency in this scenario?

Restructuring data structures can improve code efficiency by organizing data in a more logical and efficient way, making it easier to access and manipulate. By using appropriate data structures such as arrays, objects, or maps, we can optimize the code for better performance and readability. 

// Before restructuring data structures
$users = [
    ['id' => 1, 'name' => 'Alice', 'age' => 25],
    ['id' => 2, 'name' => 'Bob', 'age' => 30],
    ['id' => 3, 'name' => 'Charlie', 'age' => 35],
];

foreach ($users as $user) {
    echo $user['name'] . ' is ' . $user['age'] . ' years old. <br>';
}

// After restructuring data structures
$users = [
    1 => ['name' => 'Alice', 'age' => 25],
    2 => ['name' => 'Bob', 'age' => 30],
    3 => ['name' => 'Charlie', 'age' => 35],
];

foreach ($users as $id => $user) {
    echo $user['name'] . ' is ' . $user['age'] . ' years old. <br>';
}
