How can arrays be properly closed and structured in PHP code?

To properly close and structure arrays in PHP code, you can use the array() function to create an array with key-value pairs or values. This function allows you to organize data in a structured way within the array. Additionally, you can use square brackets [] to access or modify array elements. 

// Creating an array with key-value pairs
$person = array(
    'name' => 'John Doe',
    'age' => 30,
    'city' => 'New York'
);

// Accessing array elements
echo $person['name']; // Output: John Doe

// Modifying array elements
$person['age'] = 35;
