Are there any best practices for rounding numbers in PHP to whole thousands?

When rounding numbers in PHP to whole thousands, you can use the ceil() function to round up to the nearest thousand. This function takes a number as input and returns the next highest integer value. To round a number to the nearest thousand, divide the number by 1000, apply the ceil() function, and then multiply by 1000 again to get the rounded value.

$number = 4567;
$rounded = ceil($number / 1000) * 1000;
echo $rounded; // Output: 5000
