Are there any best practices or recommendations for managing arrays with mixed numerical indexes and associative keys in PHP?

When managing arrays with mixed numerical indexes and associative keys in PHP, it is important to maintain consistency in accessing and manipulating array elements. One recommended approach is to use the array functions provided by PHP, such as array_values() and array_keys(), to work with the array elements effectively. Additionally, documenting the structure of the array and following a consistent naming convention for keys can help improve code readability and maintainability.

// Example code snippet demonstrating best practices for managing arrays with mixed numerical indexes and associative keys in PHP

// Define an array with mixed numerical indexes and associative keys
$array = [
    'name' => 'John',
    0 => 'apple',
    1 => 'banana',
    'age' => 30,
];

// Access array elements using array_values() and array_keys()
$values = array_values($array);
$keys = array_keys($array);

// Output array values and keys
print_r($values);
print_r($keys);
