What is the best way to sort a multidimensional array in PHP based on a specific column?

When sorting a multidimensional array in PHP based on a specific column, you can use the `array_multisort()` function along with array_column() to extract the values of the specified column for sorting. This function allows you to sort the array based on the values of a specific column while maintaining the association between the keys and values of the array elements. 

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

// Extract the 'age' column values
$ages = array_column($data, 'age');

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

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