What are some strategies for following the array structure correctly in PHP to access specific attributes within multidimensional arrays?

When working with multidimensional arrays in PHP, it is important to follow the array structure correctly to access specific attributes within the arrays. One strategy is to use nested foreach loops to iterate through the arrays and access the desired attributes. Another approach is to use array keys to directly access the nested arrays. Additionally, you can use functions like array_column() or array_map() to extract specific attributes from multidimensional arrays. 

// Example of accessing specific attributes within multidimensional arrays
$users = [
    ['name' => 'John', 'age' => 30],
    ['name' => 'Jane', 'age' => 25],
    ['name' => 'Alice', 'age' => 35]
];

// Using nested foreach loops
foreach ($users as $user) {
    echo $user['name'] . ' is ' . $user['age'] . ' years old.' . PHP_EOL;
}

// Directly accessing nested arrays using array keys
echo $users[0]['name']; // Output: John

// Using array_column() to extract specific attributes
$names = array_column($users, 'name');
print_r($names); // Output: Array ( [0] => John [1] => Jane [2] => Alice )
