What are the key considerations to keep in mind when using associative arrays in PHP to handle complex data structures?

When using associative arrays in PHP to handle complex data structures, it is important to consider the keys you are using to access the data. Make sure the keys are unique and meaningful to easily retrieve the values later on. Additionally, consider the performance implications of using associative arrays for large datasets, as accessing elements by keys can be slower compared to indexed arrays. 

// Example of using associative arrays to handle complex data structures
$person = [
    'name' => 'John Doe',
    'age' => 30,
    'email' => 'johndoe@example.com'
];

// Accessing values using keys
echo $person['name']; // Output: John Doe
echo $person['age']; // Output: 30
echo $person['email']; // Output: johndoe@example.com
