How does using arrays compare to variable variables for storing and accessing data in PHP?

Using arrays is generally a more efficient and organized way to store and access data in PHP compared to variable variables. Arrays allow you to group related data together and access it using keys or indexes, making it easier to manage and manipulate. Variable variables, on the other hand, can lead to confusion and make the code harder to read and maintain. 

// Using arrays to store and access data
$person = [
    'name' => 'John',
    'age' => 30,
    'city' => 'New York'
];

echo $person['name']; // Output: John

// Using variable variables to store and access data
$name = 'John';
$age = 30;
$city = 'New York';

$variableName = 'name';
echo $$variableName; // Output: John
