Are there any specific PHP functions or methods that can help in efficiently working with multidimensional arrays?

Working with multidimensional arrays in PHP can sometimes be challenging, especially when it comes to efficiently accessing, manipulating, or iterating over the nested arrays. To address this, PHP provides several built-in functions and methods that can help simplify working with multidimensional arrays. Some of these functions include array_map(), array_walk_recursive(), array_column(), and array_reduce(). 

// Example of using array_column() to efficiently extract values from a multidimensional array
$students = [
    ['name' => 'Alice', 'age' => 21],
    ['name' => 'Bob', 'age' => 22],
    ['name' => 'Charlie', 'age' => 23]
];

$names = array_column($students, 'name');
print_r($names);
