php rounding number

I need to round off a number (non-float) to the next 10, not the closest 10. I have been trying for a long time and cant figure out how to do it.

Here is a simple function. I've tested it and it works.

This will output: 6

You can add a preg_match() to the function to make sure that only numbers will work. (i.e. Text.text won't be turned through the function)

Just use modulus and get the remainder when dividing by ten. If the remainder is 5 or greater, add 10-remainder to it.

Edit: Wait, the next ten? Ok. Modulus 10. Do 10-remainder and add it to the number.

I'm assuming I misunderstood your first post. Otherwise, it's a fairly simple algorithm. I'll post the code if you need it.

Good luck

original number is $number, rounded up is $round.

$num = substr(floor($number), 0, -1);
$round = ++$num*10;

ends up that wasent what I needed to do for the problem I had. thanks anyway

An even simplier function - ceil() :P

Yea, ceil will do it but that's not what he's asking for. My solution would work.
