My Answer:
- Round a number up to the nearest multiple of 5 in PHP
- PHP round up to 2 decimal places

You can use the `ceil()` function in PHP to round a number up to the nearest integer. To round a number up to three decimal places, you can multiply the number by 1000, use `ceil()` to round it to the nearest integer, and then divide by 1000 to get the rounded number with three decimal places. Here's an example:

php

$number = 12.3456;

$roundedNumber = ceil($number * 1000) / 1000;

echo $roundedNumber; // Output: 12.346
