What is a more efficient way to extract data from an array without relying on specific index values in PHP?

When extracting data from an array in PHP, relying on specific index values can be inefficient and error-prone, especially if the array structure changes. A more efficient way to extract data is by using array functions like `array_values()` or `array_keys()` to retrieve values without relying on specific index positions. 

$data = ['apple', 'banana', 'cherry'];

// Extract data without relying on specific index values
$values = array_values($data);
$keys = array_keys($data);

print_r($values);
print_r($keys);
