round a number to the nearest tenth in php

To round a number to the nearest tenth, you can use the built-in round function in PHP. You'll need to specify the number of decimal places you want to round to using the second parameter of the function.

Here's an example of how to round a number to the nearest tenth in PHP:

main.php
$num = 12.3456;
$rounded_num = round($num, 1); // 12.3

In this example, we're rounding the number $num to one decimal place, which will round it to the nearest tenth. The resulting value, stored in $rounded_num, will be 12.3.
