How can PHP array functions like array_multisort be utilized to sort data efficiently?

When dealing with arrays in PHP, it is often necessary to sort the data efficiently. PHP provides array functions like array_multisort that can be utilized to sort arrays based on multiple criteria. By using array_multisort, you can easily sort arrays in ascending or descending order based on one or more columns. 

// Sample array to be sorted
$data = array(
    array('id' => 1, 'name' => 'John', 'age' => 25),
    array('id' => 2, 'name' => 'Jane', 'age' => 30),
    array('id' => 3, 'name' => 'Alice', 'age' => 20),
);

// Sort the array by 'age' column in ascending order
array_multisort(array_column($data, 'age'), SORT_ASC, $data);

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