Truncate Number (or something like it)

[marcusd687]

I'm developing a script and need some help figuring out this code.

I will provide the script with a number in the url called $i (index.php?i=20048)

I need the script to multiply the number by 300 then echo the first four digits of the result.

Ex 200048*300 = 60014400
The script should echo 6001

Any ideas?
Thanks!

Multiply by 300 using normal math operators, and use [man]substr/man to retrieve the first 4 characters.

$total = $_GET['id'] * 300;
echo substr($total, 0, 4);

Thanks! It works great. I know it would be something incredibly simple 🙂

Yeah, but isn't that good as well? The simpler the code, the better? :p
