How can the use of array_multisort and array_column improve the efficiency and readability of code when sorting arrays in PHP?

When sorting arrays in PHP, using array_multisort along with array_column can improve efficiency and readability. This combination allows you to sort a multidimensional array based on a specific column value without needing complex loops or custom sorting functions. By utilizing these built-in functions, you can achieve the desired sorting result with fewer lines of code and better readability. 

// Sample multidimensional array
$data = [
    ['name' => 'John', 'age' => 30],
    ['name' => 'Alice', 'age' => 25],
    ['name' => 'Bob', 'age' => 35]
];

// Sort the array based on the 'age' column
array_multisort(array_column($data, 'age'), SORT_ASC, $data);

// Output the sorted array
print_r($data);
