How can the use of arrays in PHP be a more efficient and structured alternative to variable variables?

Using arrays in PHP can be a more efficient and structured alternative to variable variables because it allows you to store related data in a single variable rather than creating multiple variables. This can make your code more organized and easier to manage, especially when dealing with large amounts of data. Additionally, arrays provide built-in functions for sorting, searching, and manipulating data, which can help streamline your code and improve performance.

// Using arrays instead of variable variables
$person = [
    'name' => 'John',
    'age' => 30,
    'email' => 'john@example.com'
];

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