Approximate count in PHP

Question

I have a website that contains a list of articles. I want to include a line that says how many articles there are in the DB, however I don't want it to show the exact count.

I would like it to round down to the nearest 10, so for example for 105 articles I would like it to say "100+", etc.

How would I go about doing this?

Answer 1

Quite simple:

floor($num / 10) * 10

Answer 2

To do something similar you have to use the logarithm with base = 10 and round it

$exp= floor(log($num)/log(10));
$num = pow(10,$exp)."+";

This works with 10, 100, 1000 ecc, i think it better do what you asked.
