What is the best practice for sorting an associative array in PHP based on a specific column value?

When sorting an associative array in PHP based on a specific column value, 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 columns. You can specify the column you want to sort on and the sorting order (ascending or descending). 

// Sample associative array
$users = array(
    array('id' => 1, 'name' => 'Alice', 'age' => 30),
    array('id' => 2, 'name' => 'Bob', 'age' => 25),
    array('id' => 3, 'name' => 'Charlie', 'age' => 35)
);

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

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