How can you sort a two-dimensional array in PHP in ascending or descending order based on a specific column?

When sorting a two-dimensional array in PHP based on a specific column, you can use the `array_multisort()` function. This function allows you to sort multiple arrays or a multi-dimensional array based on one or more related columns. By specifying the column you want to sort on and the sorting order (ascending or descending), you can easily rearrange the elements in the array according to your requirements.

// Sample two-dimensional array
$array = array(
    array('name' => 'John', 'age' => 25),
    array('name' => 'Alice', 'age' => 30),
    array('name' => 'Bob', 'age' => 20)
);

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

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