What are the advantages of using associative keys in PHP arrays?

When using associative keys in PHP arrays, we can easily access values by specifying a specific key, making it more intuitive and readable compared to indexed arrays. Associative keys also allow us to store data in a more structured and organized manner, which can improve code maintainability and readability. Additionally, associative keys provide flexibility in terms of adding, updating, and removing elements from the array without worrying about the order of elements. 

// Using associative keys in PHP arrays
$person = array(
    'name' => 'John Doe',
    'age' => 30,
    'email' => 'john.doe@example.com'
);

echo $person['name']; // Output: John Doe
echo $person['age']; // Output: 30
echo $person['email']; // Output: john.doe@example.com
