How can developers ensure that sorting in PHP queries is done accurately for multi-digit numbers?

When sorting multi-digit numbers in PHP queries, developers should ensure that the sorting is done accurately by using the `SORT_NUMERIC` flag in the `array_multisort()` function. This flag tells PHP to compare items numerically rather than as strings, which can lead to incorrect sorting of multi-digit numbers.

// Sample array of multi-digit numbers
$numbers = [10, 5, 100, 20, 3];

// Sort the array numerically
array_multisort($numbers, SORT_NUMERIC);

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