Are there any best practices for efficiently handling array manipulation in PHP, specifically when dealing with nested arrays?

When dealing with nested arrays in PHP, it is important to use built-in array functions like array_map, array_walk_recursive, and recursion to efficiently manipulate the arrays. These functions help in iterating through nested arrays and performing operations on each element without the need for complex loops or manual traversal. 

// Example of efficiently handling array manipulation with nested arrays using array_walk_recursive

$data = [
    'name' => 'John',
    'age' => 30,
    'children' => [
        ['name' => 'Alice', 'age' => 5],
        ['name' => 'Bob', 'age' => 8]
    ]
];

// Function to double the age of children
function doubleAge(&$item, $key) {
    if ($key === 'age') {
        $item *= 2;
    }
}

array_walk_recursive($data, 'doubleAge');

print_r($data);
