Are there any specific considerations to keep in mind when working with associative arrays in PHP to maintain code readability and efficiency?

When working with associative arrays in PHP, it is important to maintain code readability and efficiency by using meaningful keys and avoiding nested arrays whenever possible. Additionally, consider using built-in array functions like array_key_exists() and foreach loops for better performance. 

// Example of using meaningful keys and foreach loop for better readability and efficiency
$person = [
    'name' => 'John Doe',
    'age' => 30,
    'email' => 'johndoe@example.com'
];

foreach ($person as $key => $value) {
    echo "$key: $value\n";
}
