What are the best practices for debugging PHP code when trying to access specific attributes within multidimensional arrays?

When trying to access specific attributes within multidimensional arrays in PHP, it's important to use proper debugging techniques to ensure you are targeting the correct keys and values. One common practice is to use var_dump() or print_r() functions to inspect the structure of the array and pinpoint the exact path to the attribute you want to access. Additionally, using nested foreach loops or array access methods can help traverse the multidimensional array efficiently. 

// Example of debugging and accessing specific attributes within a multidimensional array

// Sample multidimensional array
$users = [
    [
        'id' => 1,
        'name' => 'John Doe',
        'email' => 'john@example.com',
        'address' => [
            'street' => '123 Main St',
            'city' => 'Anytown',
            'country' => 'USA'
        ]
    ],
    [
        'id' => 2,
        'name' => 'Jane Smith',
        'email' => 'jane@example.com',
        'address' => [
            'street' => '456 Elm St',
            'city' => 'Othertown',
            'country' => 'Canada'
        ]
    ]
];

// Debugging the array structure
var_dump($users);

// Accessing specific attributes
foreach ($users as $user) {
    echo "User ID: " . $user['id'] . "<br>";
    echo "User Name: " . $user['name'] . "<br>";
    echo "User Email: " . $user['email'] . "<br>";
    echo "User Address: " . $user['address']['street'] . ", " . $user['address']['city'] . ", " . $user['address']['country'] . "<br>";
}
